+		    GNU GENERAL PUBLIC LICENSE
+		       Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+     59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+		    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+			    NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+	    How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) 19yy  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program; if not, write to the Free Software
+    Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
+
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) 19yy name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989
+  Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+	partitions to harddrives(in builtins.c). Fixed a bug that causes

+	failure when `find --set-root' on a CD-ROM device(in builtins.c). Added

+	a new feature of directly chainloading ntldr and some dos kernels.

+

+2005-11-14 version 0.4.1pre32

+	Added ram disk device (rd) to access, typically, the initrd image.

+	Added many new command-line options for bootlace.com to install GRLDR

+	boot record onto the boot sector of a floppy. A few bugs about

+	"map --mem" were fixed. Another bug about finding grldr in NTFS was

+	also fixed. It may cause the machine to hang up when there is no ntfs

+	boot record in the boot area of the NTFS partition.

+

+2005-09-25 version 0.4.1pre28

+	Commandline option --config-file="FILENAME_OR_RAW_COMMANDS" was added

+2005-05-17 version 0.4.1pre3

+	Search for cdrom_drive from drive 0x88 to drive 0xff

+

+2005-05-11 version 0.4.1pre2

+	Our base is now upgraded to GNU GRUB 0.97.

+

+2005-04-25 version 0.4.1pre

+	Fixed a bug reported by Gilles van Ruymbeke

+	<gvr_no_spam_123@ruymbeke.com> <gvr_grub4dos123@ruymbeke.ch>:

+	

+	The map_func improperly opened the emulation image for 3 times, that

+	might slow down the load speed heavily, especially for gzipped files.

+

+2005-04-15 version 0.4.0

+	Add /boot/grub/menu.lst in preset menu. This is final.

+

+2005-04-07 version 0.4.0pre7

+	config_file takes precedence over preset_menu.

+

+2005-04-06 version 0.4.0pre6

+	GRLDR can be used with no-emulation-mode bootable CD-ROM.

+

+2005-03-09 version 0.4.0pre4

+	Now preset menu find /menu.lst, no longer support /boot/grub/menu.lst

+

+	Partition images can emulate a partition (hd?,0) with --mem option.

+

+2005-03-02 version 0.4.0pre3

+	chainloader can boot images larger than 512 bytes, and can load image

+	to a different location than 0000:7C00.

+

+2005-02-06 version 0.4.0pre

+	Switched to GNU GRUB 0.96

+	The --mem option of MAP command was added for memdrive emulation.

+

+	Also announced 0.2.0 final.

+

+	GRUB.EXE runs in DOSBOX.

+	GRUB4LIN is introduced to boot off LINUX.

+	Fixed a bug reported by windrv: NTFS check contiguity failure

+	Rearranged the patches.

+

+2004-08-31 version 0.2.0pre12

+	Fixed a bug reported by szwp: cannot load GRLDR on partition that is

+	not CHS-accessible.

+

+	Fixed a bug reported by windrv: take too much time to check contiguity

+

+2004-08-15 version 0.2.0pre11

+	Mark the scdrom module as experimental.

+

+2004-07-13 version 0.2.0pre9

+	Merged GNU GRUB 0.95

+

+	BOOTGRUB removed. Use BOOT.INI line C:\GRLDR="Start GRUB" instead.

+

+	Patches from Gandalf: NTFS and ATAPI CDROM support(also thanks to

+	Tobias Svensson <tobiassvensson@home.se>)

+

+	Patches from Chris Semler <csemler@mail.com>: findroot

+

+2004-04-12 version 0.2.0pre6

+	Now GRUB.EXE can be used in CONFIG.SYS this way:

+

+	shell=C:\some\where\grub.exe --config-file=(hd0,0)/boot/grub/menu.lst

+

+	or

+

+	shell=C:\some\where\grub.exe

+

+	No other changes.

+

+2004-04-09 version 0.2.0pre5

+	Now BOOTGRUB contains 4 sectors, i.e., 2048 bytes. Optionally, you may

+	copy the 2nd, 3rd and 4th sectors of BOOTGRUB to the three sectors that

+	immediately follow the MBR. Also Optionally, you may copy 446 bytes

+	from the very beginning of BOOTGRUB to the very beginning of MBR. In

+	this way, the GRLDR can be started out of MBR, without the presence of

+	NTLDR.

+

+	CAUTION: Don't copy 512 bytes to MBR. The partition table should not

+	be overwritten. The partition table is in the end of MBR. If you make

+	a mistake, you will lose your whole system!!

+

+2004-02-18 version 0.2.0pre4

+	Arbitrary-size floppy and hard disk emulation finally implemented.

+	GRUB for NTLDR is included. See README file.

+	Splash image version is available in the SPLASH directory.

+	

+2003-09-23 version 0.1.4 -- development unstable release

+	Unfortunately 0.1.3 has an ugly bug. Fixed.

+

+2003-09-01 version 0.1.3 -- development unstable release

+	Rewrite the code for guessing FreeDOS int vectors. Hopefully it works

+	for all the future versions of FreeDOS :-)

+

+2003-08-25 version 0.1.2 -- development unstable release

+	Fixed a small bug that affects the read of the emulated floppy sectors.

+	

+	Added some files (including the menu.lst file) for installing GRUB to

+	MBR from DOS. Usage:

+

+	Copy the boot directory to C:\ ; You must do this on Windows, NOT dos,

+	because DOS cannot deal with the long filenames.

+

+	Run grub to access the menu.lst file in C:\boot\grub ; Of cause on DOS.

+

+	When menu occurs, select a proper menu item for installing GRUB to MBR.

+

+	If the menu does not appear, you should get the "grub>" prompt. At the

+	prompt, type the following commands:

+

+	grub> configfile (hd0,1)/boot/grub/menu.lst

+	grub> configfile (hd0,2)/boot/grub/menu.lst

+	grub> configfile (hd0,3)/boot/grub/menu.lst

+

+	Then, the menu should occur.

+	

+2003-06-29 version 0.1.0.1 -- development unstable release

+	Do some cleanups on 0.1.0, no important changes.

+	BTW, it seems that the 0.1.0 is quite stable :-)

+	

+2003-06-29 version 0.0.8

+	Restore mapped int13 to the unmapped state while grub is invoked

+	after a previously performed drive map operation.

+

+2003-05-29 version 0.1.0 -- development unstable release

+	Floppy 1.44M drive emulation are OK. GOOD!!!! Usage:

+	

+	# boot Windows 98 SE

+	map (hd1,0)/dos98se.img (fd0)

+	chainloader (hd1,0)/dos98se.img

+	rootnoverify (fd0)

+	boot

+	

+	Another example:

+

+	# boot Mandrake hard disk installer

+	map (hd0,0)/hd.img (fd0)

+	chainloader (hd0,0)/hd.img

+	rootnoverify (fd0)

+	boot

+

+	Note that the floppy image file must size 1440KB, i.e., 1474560 bytes.

+	_AND_ also, the file must consist of one contiguous disk area, no

+	holes, no fragments. Use GRUB's blocklist command to determine whether

+	or not an image file is contiguous. It is known that a 1440KB-file is

+	always non-contiguous if it resides in an ext2 filesystem. But you may

+	get a 1440KB contiguous file with an FAT32 partition(vfat filesystem).

+

+	Floppy(and hard disk) with arbitrary sizes will be emulated in the

+	future.

+

+2003-05-06 version 0.0.7

+

+		Fixed a huge bug!! Read the following carefully!

+	

+	Using the drive map command(just as many distributions currently do)

+	

+			map TO_DRIVE FROM_DRIVE

+	

+	to boot your system could seriously _damage_ your hard disk data,

+	

+	totally and thoroughly!! This bug has just been fixed in 0.0.7 :-)

+	

+	This bug is not specific to grub_for_dos, but caused by the original

+	

+	grub-0.93 release. So do _NOT_ use map command any more until my fix is

+

+	accepted by GRUB maintainers or a similar fix is made by other

+	

+	people. For now, do _NOT_ use map command in any kind of Linux

+	

+	distributions such as Red Hat or Mandrake or any others.

+

+		Because GRUB_FOR_DOS-0.0.7 already applied the fix, so it

+	

+	should be safe to use the map command.

+

+		Another small bug was also fixed in grub_for_dos-0.0.7 :-)

+

+2003-04-29 version 0.0.6

+	Runs also on MS-DOS 3.30. No other changes.

+

+2003-04-26 version 0.0.5

+	Runs on MS-DOS 4.0, 5.0, 6.0, 6.20, 6.21, 6.22, 7.0, 7.10, 8.0 and

+	FreeDOS(build 2029). GOOD!!

+

+2003-04-20 version 0.0.4

+	Running on FreeDOS(build 2029), GOOD!! (But currently GRUB.EXE only

+	has limited FreeDOS support, maybe unstable.)

+

+	Add a "Guess DOS Version" feature. The program now exit to DOS when

+	guess failed. The previous versions of GRUB.EXE always hang when

+	running on an unsupported DOS version.

+	

+2003-04-13 version 0.0.3

+	The option "--config-file=FILE" was added.

+	

+2003-04-11 version 0.0.2

+	Also runs on MS-DOS 8.0 (i.e., the DOS with WinMe/2000/XP), GOOD!!

+	The GRUB.PIF file included, so GRUB.EXE can be started from Windows 9x

+

+2003-04-10 version 0.0.1

+	Runs on MS-DOS 7.10(Win98)

+

+------------------------------------------------------------------------------

+

+Usage:

+		GRUB [--bypass] [--time-out=T] [--hot-key=K] [--config-file=FILE]

+		

+		The FILE, for example, can be (hd0,0)/menu.lst

+		

+		In CONFIG.SYS, the line looks like:

+		

+			install=c:\some\where\grub.exe --config-file=FILE

+		

+		If no options present, GRUB.EXE simply uses

+		

+			(hd0,0)/menu.lst

+		

+		as the configure file, if it exists. (Notice! We finally

+		changed the default file from (hd0,0)/boot/grub/menu.lst to

+		(hd0,0)/menu.lst) (Changed 2006-12-23. See Update 3 below.)

+		

+		The partition (hd0,0) can be of a Windows partition or a Linux

+		partition, or any other partition type supported by GRUB.

+

+		Only GRUB-style filename is acceptable here for FILE. A DOS

+		filename won't work(it is certain we should use GRUB-style

+		filenames because DOS-filenames won't access a file in a

+		Linux ext2 partition for example).(See Update 2 below)

+

+		Update: FILE can be the contents of a menu. Use semi-colon

+		to delimitate the embedded commands here in FILE. The FILE

+		can be enclosed with a pair of double-quotes. For example:

+

+			GRUB --config-file="root (hd0,0);chainloader +1"

+

+		This command will boot the system in (hd0,0).

+

+		Another example:

+

+			GRUB --config-file="reboot"

+

+		This command will reboot the machine.

+

+		One more example:

+

+			GRUB --config-file="halt"

+

+		This command will halt the machine.

+

+		if --bypass is specified, GRUB will exit to DOS when

+		timeout reached.

+

+		The option `--time-out=T' specifies the timeout value in

+		seconds. T defaults to 5 if --bypass is specified and defaults

+		to 0 if --bypass is not specified.

+

+		The default hot key value is 0x3920(for space bar). If this

+		key is pressed, GRUB will boot normally. If another key is

+		pressed, GRUB will terminate immediately and return back to

+		DOS. See "int 16 keyboard scan codes" below.

+

+		Each option can be specified only once at most.

+

+		Update 2: DOS filenames have been supported(patched by John

+		Cobb). If the beginning two characters of FILE are "#@", then

+		the rest of FILE is taken as a DOS filename. Example:

+

+			GRUB --config-file="#@c:\menu.lst"

+

+		Only the beginning 4KB of the DOS file will be used. The file

+		should be an uncompressed text file.

+

+		Note: You may also use the `direct DOS file access' with the

+		SHELL or INSTALL line in CONFIG.SYS, but should not use it

+		with the DEVICE line. The DOS document said that a DOS device

+		driver should not call the `open file' DOS call.

+

+		Update 3(2006-12-23): By default, GRUB.EXE will locate its

+		config file in the following order:

+

+			(DOS file) .\menu.lst, the MENU.LST in the current dir.

+

+			(DOS file) \menu.lst, the MENU.LST in the root dir of

+						the current drive.

+			(GRUB file) /menu.lst, the MENU.LST in the root dir of

+						the boot device.

+

+		The default boot device is still (hd0,0).

+

+

+--------------------------------------------------------

+

+Update 1:	Version 0.2.0 also brings out a new thing, GRUB for NTLDR,

+		which could be used to boot into GRUB from the boot menu

+		of Windows NT/2000/XP. Copy GRLDR to the root directory of

+		drive C: of Windows NT/2000/XP and append to C:\BOOT.INI

+		this line:

+

+			C:\GRLDR="Start GRUB"

+

+		That will be done. The GRLDR should be in the same directory

+		as BOOT.INI and NTLDR. Note that BOOT.INI is usually hidden

+		and you must unhide it before you can see it. The filename

+		GRLDR shouldn't be changed. If GRLDR is in a NTFS partition,

+		it should be copied to the root directory of another non-NTFS

+		partition(and likewise should the menu.lst file be). If GRLDR

+		is compressed, e.g., in a NTFS partition, it will not work.

+

+		Even if the drive letter of this disk has been changed to

+		other than C by the Windows device manager, it seems you still

+		have to use the letter C here in BOOT.INI, otherwise, NTLDR

+		will fail to locate the GRLDR file.

+

+		And what's more, if you are booting NTLDR from a floppy, you

+		will have to write the GRLDR line in A:\BOOT.INI like this:

+

+			C:\GRLDR="Start GRUB"

+

+		and shouldn't use the letter A like this:

+

+			A:\GRLDR="Start GRUB"

+

+		(Note that in the case when BOOT.INI is on floppy A, the

+		notation "C:\GRLDR" actually refer to the file A:\GRLDR).

+

+

+Update 2:	GRUB for Linux is also introduced along with 0.2.0. You can

+		boot grub using a linux loader KEXEC, LILO, SYSLINUX or another

+		GRUB. (GRUB4LIN has merged into GRUB.EXE)

+

+		To boot GRUB off Linux, use this pair of commands:

+

+			kexec -l grub.exe

+			kexec -e

+

+		To boot GRUB via GRUB, use commands like the following:

+

+			kernel (hd0,0)/grub.exe

+			boot

+

+		To boot GRUB via LILO, use these lines in lilo.conf:

+

+			image=/boot/grub.exe

+			label=grub.exe

+

+		To boot GRUB via SYSLINUX, use these lines in syslinux.cfg:

+

+			label grub.exe

+				kernel grub.exe

+

+		LOADLIN may encounter problems when loading grub.exe, because

+		grub.exe requires some unchanged original BIOS interrupt

+		vectors, but DOS has destroyed them, and loadlin does not

+		recover them before it transfers control to grub.exe.

+		

+Update 3:	Beginning at version 0.4.0, GRUB for DOS supports memdrives.

+		Example:

+

+			# boot into a floppy image

+			map --mem (hd0,0)/floppy.img (fd0)

+			map --hook

+			chainloader (fd0)+1

+			rootnoverify (fd0)

+			map --floppies=1

+			boot

+

+		Because the image will be copied to a memory area, the image

+		itself can be non-contiguous and even gzipped.

+

+		Another Example:

+

+			map --mem=-2880 (hd0,0)/floppy.img (fd0)

+

+		This memdrive (fd0) will occupy at least 1440 KB of memory.

+		This is useful when the size of a 1.44M-floppy image is less

+		than 1440 KB.

+

+		One more example:

+

+			map --mem --read-only (hd0,0)/hd.img (hd1)

+

+		This memdrive is a hard drive, and read-only. That means you

+		will not be able to write data to the memdrive (hd1).

+

+		You can use many memdrives and many ordinary virtual emulated

+		disk-based drives at the same time.

+

+		If the BIOS does not support int15/EAX=e820h, you will not be

+		able to use any memdrives.

+

+Update 4:	For memdrive emulation, a single-partition image can be used

+		instead of a whole-harddrive image. Example:

+

+			map --mem (hd0,7)/win98.img (hd0)

+			map --hook

+			chainloader (hd0)+1

+			rootnoverify (hd0)

+			map --harddrives=1

+			boot

+

+		Here win98.img is a partition image without the leading MBR

+		and partition table in it. Surely GRUB for DOS will build an

+		MBR and partition table for the memdrive (hd0).

+

+Update 5:	Now GRLDR can be used as a no-emulation-mode bootable CD-ROM

+		boot image. Example for Linux users:

+

+			mkdir iso_root

+			cp grldr iso_root

+			mkisofs -R -b grldr -no-emul-boot -boot-load-seg 0x1000 -o bootable.iso iso_root

+

+		As an alternative, grldr can also be used the same way as

+		stage2_eltorito. The -boot-info-table option is allowed but you

+		can omit it:

+

+			mkdir iso_root

+			cp grldr iso_root

+			mkisofs -R -b grldr -no-emul-boot -boot-load-size 4 -o grldr.iso iso_root

+

+		Also note that the bootable.iso above must be created with the

+		-boot-load-seg 0xHHHH option where HHHH is greater than or

+		equal to 1000(hex). If HHHH < 1000(hex), QEMU will hang. This

+		is a bug in QEMU. The grldr.iso can be created with or without

+		-boot-load-seg 0xHHHH option.

+

+		The menu.lst file should be placed in the root dir of the CD.

+

+Update 6:	The Chinese special build is in the "chinese" subdirectory.

+		(patched by Gandalf, 2005-06-27)

+

+		The Chinese special build also has scdrom builtin.

+		(update: scdrom has been dropped since 2006-07-20)

+

+Update 7:	Added memory drive (md). Like (nd) for network drive and (cd)

+		for CD-ROM drive, a new drive (md) is implemented for accessing

+		the whole memory as a disk drive. (md) only works for systems

+		with BIOS int15/EAX=E820h support.

+

+		The cat command now has a few new options: --hex for hexdump,

+		and --locate=STRING for string search in file.

+

+		Typical examples:

+

+			cat --hex (hd0)+1

+

+		It will display the MBR sector in hex form.

+

+			cat --hex (md)+2

+

+		It will display 1KB of your memory(in fact, it is the real-mode

+		IDT table), also in hexdump form.

+		

+			cat --hex (md)0x800+1

+

+		It will display 1 sector of your extended memory.

+

+			cat --hex (hd0,0)+1

+

+		It will display the first sector of partition (hd0,0). Usually

+		this sector contains the boot record of an operating system.

+

+Update 8:	Added ram drive (rd). The (md) device accesses the memory

+		starting at physical address 0. But (rd) accesses memory

+		starting at any base address. The base and length of the ram

+		drive can be specified through the map command. "help map" for

+		details. You can even specify the BIOS drive number used for

+		the (rd) drive, e.g., map --ram-drive=0xf0. The default drive

+		number for (rd) is 0x7F which is a floppy. If (rd) is a hard

+		drive image, you should change the drive number to a value

+		greater than or equal to 0x80(but should avoid using 0xffff,

+		because 0xffff is for the (md) device).

+

+		The notation (rd)+1 always represents the file which contains

+		all the bytes stored in (rd).

+

+Update 9:	Directly boot NTLDR of WinNT/2K/XP and IO.SYS of Win9x/ME and

+		KERNEL.SYS of FreeDOS. Examples:

+

+			chainloader --edx=0xPPYY (hd0,0)/ntldr

+			boot

+

+			chainloader --edx=0xYY (hd0,0)/io.sys

+			boot

+

+			chainloader --ebx=0xYY (hd0,0)/kernel.sys

+			boot

+

+		Hex YY specifies the boot drive number, and hex PP specifies

+		the boot partition number of NTLDR. If the boot drive is

+		floppy, PP should be the hex value ff, i.e., decimal 255.

+

+		For KERNEL.SYS of FreeDOS, the --edx won't work,

+		use --ebx please.

+

+		The option --edx ( --ebx ) can be omitted if the file is in

+		its normal place. But in some cases, those options are needed.

+

+		If, e.g., the ntldr file is in an ext2 partition called

+		(hd2,8) while you want it to think of the Windows partition

+		(hd0,7) as the boot partition, then --edx is required:

+

+			chainloader --edx=0x0780 (hd2,8)/ntldr

+

+		For DOS kernels(i.e., IO.SYS and KERNEL.SYS), the boot

+		partition number is meaningless, so you only need to specify

+		the correct boot drive number YY(but specifying the boot

+		partition number is harmless).

+

+		The above PPYY can also be specified by using a root or

+		rootnoverify command after the chainloader command. Examples:

+

+			chainloader (hd2,6)/kernel.sys

+			rootnoverify (hd0)	<-------- YY=80

+			boot

+

+			chainloader (hd0,0)/ntldr

+			rootnoverify (hd0,5)	<-------- YY=80, PP=05

+			boot

+

+		Tip: CMLDR (the ComMand LoaDeR, which is used to load the

+		Windows Fault Recovery Console) can be chainloaded as well

+		as NTLDR.

+

+		Bean has successfully decompressed and booted IO.SYS of WinME.

+		Thanks for the great job!

+

+Update 10:	isolinux.bin (version 3.73) can be chainloaded as with build

+		2009-02-09.

+

+			chainloader (cd)/isolinux.bin

+

+		isolinux.bin must reside in a real or virtual cdrom.

+

+Update 11:	stage2 of Grub Legacy can be chainloaded in this way:

+

+			chainloader --force --load-segment=0 --load-offset=0x8000 --boot-cs=0 --boot-ip=0x8200 (...)/.../stage2

+

+--------------------------------------------------------

+

+	There is no full documentation in English at present. Here are some

+	examples showing the usage of disk emulation commands:

+

+1.	Emulates HD partition C: as floppy drive A: and boot win98 from C:

+

+		map --read-only (hd0,0)+1 (fd0)

+		chainloader (hd0,0)+1

+		rootnoverify (hd0)

+		boot

+

+	In the above example, (hd0,0) is drive C: with win98 on it. After win98

+	boot complete, you will find that A: contains all files of C:, and if

+	you delete files in A:, the files in C: will also disappear.

+

+	At the map command line, the notation (hdm,n)+1 is interpreted to

+	represent the whole partition (hdm,n), not just the first sector of the

+	partition.

+

+2.	Emulates HD partition C: as floppy drive A: and boot win98 from A:

+

+		map --read-only (hd0,0)+1 (fd0)

+		map --hook

+		chainloader (fd0)+1

+		rootnoverify (fd0)

+		map --floppies=1

+		boot

+

+	After the "map --hook" command, the emulation takes effect instantly

+	even in the GRUB command line.

+	

+	Note that the (fd0) in "chainloader (fd0)+1" is the emulated virtual

+	floppy A:, not the real floppy diskette(because map is hooked now).

+

+

+3.	Emulates an image file as floppy drive A: and boot win98 from C:

+

+		map --read-only (hd0,0)/floppy.img (fd0)

+		chainloader (hd0,0)+1

+		rootnoverify (hd0)

+		map --floppies=1

+		map --harddrives=1

+		boot

+

+4.	Emulates an HD partition as the first hard disk and boot DOS from it:

+

+		map --read-only (hd2,6)+1 (hd0)

+		map --hook

+		chainloader (hd0,0)+1

+		rootnoverify (hd0)

+		map --harddrives=1

+		boot

+

+	In this example, (hd2,6)+1 represents an extended logical DOS partition

+	of the third BIOS hard disk (hd2).

+

+	If a DOS partition is used to emulate a hard disk, GRUB for DOS will

+	first try to locate the partition table, usually 63 sectors ahead of

+	the DOS partition. GRUB for DOS will refuse the emulation if the

+	partition table is not there.

+

+5.	Emulates an image file as the first hard disk and boot DOS from it:

+

+		map --read-only (hd0,0)/harddisk.img (hd0)

+		chainloader --load-length=512 (hd0,0)/harddisk.img

+		rootnoverify (hd0)

+		map --harddrives=1

+		boot

+

+	If an image file is used to emulate a hard disk, the image file must

+	contain an MBR. In other word, the first sector of HARDDISK.IMG must

+	contain the partition table of the emulated virtual hard disk.

+

+Note:	Counters for floppies and harddrives in the BIOS Data Area remain

+	unchanged during the mapping. You should manually set them to proper

+	values with `map --floppies=' and/or `map --harddrives=', especially,

+	e.g., when there is no real floppy drive attached to the mother board.

+	If not doing so, DOS might fail to start.

+

+	`map --status' can report the values. Note also that `map --floppies='

+	and `map --harddrives=' can be used independently without the

+	appearance of mappings.

+

+	0.4.2 has introduced a new variable, memdisk_raw, to simulate the

+	memdisk-like raw mode. If the BIOS has no int15/87h, or if it has

+	buggy int15/87h support, you should set this variable before any

+	memdrives are used. Here is an example:

+

+		map --memdisk-raw=1

+		map --mem (hd0,0)/floppy.img (fd0)

+		map --hook

+		chainloader (fd0)+1

+		rootnoverify (fd0)

+		boot

+

+	If you encountered a memdrive failure without using

+	map --memdisk-raw=1, you should have a try with `map --memdisk-raw=1'.

+

+	If you `map --memdisk-raw=0' later, you should afterwards do a

+	`map --unhook'(and followed by a `map --hook' if needed).

+

+	Update: memdisk_raw now defaults to 1. You should `map --memdisk-raw=0'

+	if you want to use int15/87h to access memdrives.

+

+--------------------------------------------------------

+	

+	Floppies/harddisks of any size can be emulated with GRUB for DOS 0.2.0.

+	

+	Image file must be contiguous, or else GRUB for DOS will refuse it.

+

+	The `blocklist' command can list fragments or pieces of a file.

+

+	Type "help map" at the GRUB prompt to get a brief description of the

+	command.

+

+	The form 

+	

+		map ... (fd?)

+	

+	is a floppy emulation, and the form

+	

+		map ... (hd?)

+	

+	is a hard disk emulation.

+

+	When a HARD DISK emulation is used, better not start Windows for

+	security reasons. Windows may even destroy all data and all information

+	on all your real hard disks!!!!!!!!

+	

+	Update for --mem: when --mem is used, it seems rather safe even after

+	entering Windows. Win98 can operate the memdrive normally.

+

+	Windows NT/2000/XP does not recognize the emulated drives no matter

+	whether the --mem option is present.

+******************************************************************************

+

+1. Ext2 Boot Sector/Boot Record Layout (for loading grldr)

+------------------------------------------------------------------------------

+An EXT2/EXT3 volume can be GRUB-bootable. Copy grldr and an optional menu.lst

+to the root dir of the EXT2/EXT3 volume, and build the boot sector based on the

+fifth sector of grldr(some fields need to be changed as detailed in the

+following table). And then the EXT2/EXT3 volume is GRUB-bootable.

+

+Update:	bootlace.com is a DOS/Linux utility that can install the GRLDR boot

+record onto the first sector of an EXT2/EXT3 volume.

+

+Offset	Length	Description

+======	======	==============================================================

+00h	2	Machine code for short jump over the data.

+

+02h	1	LBA indicator. Valid values are 0x02 for CHS mode, or 0x42 for

+		LBA mode.

+

+		If the BIOS int13 supports LBA, this byte can be safely set to

+		0x42.

+

+		Some USB BIOSes might have bugs when using CHS mode, so the

+		format program should set this byte to 0x42. It seems that

+		(generally) all USB BIOSes have LBA support.

+

+		If the format program does not know whether the BIOS has LBA

+		support, it may operate this way:

+

+		if (partition_start + total_sectors_in_partition) exceeds the

+		CHS addressing ability(especially when it is greater than

+		1024*256*63), the caller should set this byte to 0x42,

+		otherwise, set to 0x02.

+

+		Note that Windows98 uses the value 0x0e as the LBA indicator.

+

+		Update: this byte of LBA indicator is ignored. The boot

+		record can probe the LBA support of BIOS.

+

+03h	10	OEM name string (of OS which formatted the disk).

+		Update: this field is now used for error message of "I/O error"

+

+0Dh	1	Sectors per block. Valid values are 2, 4, 8, 16 and 32.

+

+0Eh	2	Bytes per block. Valid values are 0x400, 0x800, 0x1000, 0x2000

+		and 0x4000.

+

+10h	4	Pointers in pointers-per-block blocks, that is, number of

+		blocks covered by a double-indirect block.

+

+		Valid values are 0x10000, 0x40000, 0x100000, 0x400000 and

+		0x1000000.

+

+14h	4	Pointers per block, that is, number of blocks covered by an

+		indirect block.

+

+		Valid values are 0x100, 0x200, 0x400, 0x800, 0x1000.

+

+18h	2	Sectors per track.

+

+1Ah	2	Number of heads/sides.

+

+1Ch	4	Number of hidden sectors (those preceding the boot sector).

+

+		Also referred to as the starting sector of the partition.

+

+		For floppies, it should be 0.

+

+20h	4	Total number of sectors in the filesystem(or in the partition).

+

+24h	1	BIOS drive number of the boot device.

+

+		Actually this byte is ignored for read. The boot code will

+		write DL onto this byte. The BIOS or the caller should set

+		drive number in DL.

+

+		We assume all BIOSes pass correct drive number in DL.

+		Buggy BIOSes are not supported!!

+

+25h	1	Partition number of this partition on the boot drive.

+

+		0, 1, 2, 3 are primary partitions.

+		4, 5, 6, ... are logical partitions in the extended partition.

+

+		0xff is for whole drive. So for floppies, it should be 0xff.

+

+26h	2	inode size in bytes. (Notice! We use the formerly reserved

+		word here for inode size!)

+

+28h	4	Number of inodes per group.

+

+		Normally a 1.44M floppy has only one group, and the total

+		number of inodes is 184. So the value should be	184 or

+		greater.

+

+2Ch	4	The block number for group descriptors.

+

+		Valid values are 2 for 1024-byte blocks, and 1 otherwise.

+

+		The value here is equal to (s_first_data_block + 1).

+

+30h	1	code for "cld"(0xFC).

+

+31h	2	code for "xor ax,ax"(0x31, 0xC0).

+

+33h	1	code for "nop"(0x90) or "cwd"(0x99)

+

+34h	458	The rest of the machine code.

+

+1FEh	2	Boot Signature AA55h.

+

+2. FAT12/FAT16 Boot Sector/Boot Record Layout (for loading grldr)

+------------------------------------------------------------------------------

+A FAT12/16 volume can be GRUB-bootable. Copy grldr and an optional menu.lst to

+the root dir of the FAT12/16 volume, and build the boot sector based on the

+fourth sector of grldr(some fields need to be changed as detailed in the

+following table). And then the FAT12/16 volume is GRUB-bootable.

+

+Update:	bootlace.com is a DOS/Linux utility that can install the GRLDR boot

+record onto the boot sector of an FAT12/16 volume.

+

+Offset	Length	Description

+======	======	==============================================================

+00h	2	Machine code for short jump over the data.

+

+02h	1	LBA indicator. Valid values are 0x90 for CHS mode, or 0x0e for

+		LBA mode.

+

+		If the BIOS int13 supports LBA, this byte can be safely set to

+		0x0e.

+

+		Some USB BIOSes might have bugs when using CHS mode, so the

+		format program should set this byte to 0x0e. It seems that

+		(generally) all USB BIOSes have LBA support.

+

+		If the format program does not know whether the BIOS has LBA

+		support, it may operate this way:

+

+		if (partition_start + total_sectors_in_partition) exceeds the

+		CHS addressing ability(especially when it is greater than

+		1024*256*63), the caller should set this byte to 0x0e,

+		otherwise, set to 0x90.

+

+		Update: this byte of LBA indicator is ignored. The boot

+		record can probe the LBA support of BIOS.

+

+		Update(2006-07-31): Though GRLDR won't use this LBA-indicator

+		byte, Windows 98 uses it. Usually this byte should be 0x90 for

+		CHS mode(especially for floppies). If this byte is not set

+		properly, Windows 98 will not recognize the floppy or

+		partition. This problem was reported by neiljoy. Many thanks!

+

+03h	8	OEM name string (of OS which formatted the disk).

+

+0Bh	2	Bytes per sector. Must be 512.

+

+0Dh	1	Sectors per cluster. Valid values are 1, 2, 4, 8, 16, 32, 64

+		and 128. But a cluster size larger than 32K should not occur.

+

+0Eh	2	Reserved sectors(number of sectors before the first FAT,

+		including the boot sector), usually 1.

+

+10h	1	Number of FATs(nearly always 2).

+

+11h	2	Maximum number of root directory entries.

+

+13h	2	Total number of sectors (for small disks only, if the disk is

+		too big this is set to 0 and offset 20h is used instead).

+

+15h	1	Media descriptor byte, pretty meaningless now (see below).

+

+16h	2	Sectors per FAT.

+

+18h	2	Sectors per track.

+

+1Ah	2	Total number of heads/sides.

+

+1Ch	4	Number of hidden sectors (those preceding the boot sector).

+

+		Also referred to as the starting sector of the partition.

+

+		For floppies, it should be 0.

+

+20h	4	Total number of sectors for large disks.

+

+24h	1	BIOS drive number of the boot device.

+

+		Actually this byte is ignored for read. The boot code will

+		write DL onto this byte. The BIOS or the caller should set

+		drive number in DL.

+

+		We assume all BIOSes pass correct drive number in DL.

+		Buggy BIOSes are not supported!!

+

+25h	1	Partition number of this filesystem in the boot drive.

+

+		This byte is ignored for read. The boot code will write

+		partition number onto this byte. See offset 41h below.

+

+26h	1	Signature (must be 28h or 29h to be recognised by NT).

+

+27h	4	Volume serial number.

+

+2Bh	11	Volume label.

+

+36h	8	File system ID. "FAT12   ", "FAT16   " or "FAT     ".

+

+3Eh	1	code for "cli".

+

+3Fh	1	code for "cld".

+

+40h	1	code for "mov dh, imm8".

+

+41h	1	Partition number of this partition on the boot drive.

+

+		0, 1, 2, 3 are primary partitions.

+		4, 5, 6, ... are logical partitions in the extended partition.

+

+		0xff is for whole drive. So for floppies, it should be 0xff.

+

+42h	442	The rest of the machine code.

+

+1FCh	4	Boot Signature AA550000h. (Win9x uses 4 bytes as magic value)

+

+

+3. FAT32 Boot Sector/Boot Record Layout (for loading grldr)

+------------------------------------------------------------------------------

+***   grldr.mbr - How to write it to Master Boot Track of the hard disk    ***

+******************************************************************************

+

+grldr.mbr contains code that can be used as Master Boot Record. The code is

+responsible for searching all partitions for grldr and when found, loading it.

+Currently supported partition types are: FAT12/FAT16/FAT32, NTFS, EXT2/EXT3.

+Logical partitions in the extended partition are supported, provided that the

+extended partition type is Microsoft-compatible. In fact, the Linux extended

+partition type(0x85) is not fully tested for the search mechanism.

+

+How to write GRLDR.MBR to the Master Boot Track of a hard disk?

+

+First, read the Windows disk signature and partition information bytes

+(72 bytes in total, from offset 0x01b8 to 0x01ff of the MBR sector), and put

+them on the same range from offset 0x01b8 to 0x01ff of the beginning sector of

+GRLDR.MBR.

+

+Optionally, if the MBR in the hard disk is a single sector MBR created by

+Microsoft FDISK, it may be copied onto the second sector of GRLDR.MBR.

+

+The second sector of GRLDR.MBR is called "previous MBR". When GRLDR not found,

+"previous MBR" will be started.

+

+No other steps needed, after all necessary changes stated above have been made,

+now simply write GRLDR.MBR on to the Master Boot Track. That's all.

+

+Note: The Master Boot Track means the first track of the hard drive.

+

+Note: The bootstrap code of GRLDR.MBR only finds GRLDR file in the root dir of

+a partition. You'd better place menu.lst file accompanying with GRLDR(i.e., in

+the same root dir of the same partition as GRLDR).

+

+The filename "grldr" in an ext2 partition must be in lower case letters, and

+the file type of grldr must be plain regular. Other types, e.g., a symbolic

+link, won't work.

+

+Update:	bootlace.com is a DOS/Linux utility for installing grldr.mbr to MBR.

+The whole grldr.mbr is embedded in the body of the bootlace.com utility, so

+bootlace.com can be used independently. See below.

+

+

+06h	1	preferred boot drive number, 0xff for no-drive

+07h	1	preferred partition number, 0xff for whole drive

+

+			(fd0)

+

+		otherwise, if the preferred boot drive number is Y(not equal to

+		0xff) and the preferred partition number is K, then the order of

+		the search for GRLDR will be:

+

+			(Y) if K=0xff; or (Y,K) otherwise

+			(hd0,0), (hd0,1), ..., (hd0,L),(L=max partition number)

+						       (X=max harddrive number)

+			(fd0)

+

+		Note: if Y < 0x80, then (Y) is floppy, else (Y) is harddrive,

+		      and (Y,K) is partition number K on harddrive (Y).

+***        bootlace.com - Install GRLDR.MBR bootstrap code to MBR          ***

+******************************************************************************

+

+BOOTLACE.COM installs GRLDR.MBR boot record to the MBR of a harddrive or of a

+harddrive image file, or to the boot sector of a floppy or a floppy image.

+

+Usage:

+

+	bootlace.com  [OPTIONS]  DEVICE_OR_FILE

+

+OPTIONS:

+

+	--read-only		do everything except the actual write to the

+				specified DEVICE_OR_FILE.

+

+	--restore-mbr		restore the previous mbr.

+

+	--mbr-no-bpb		do not copy BPB in the boot sector of the

+				leading FAT partition to MBR.

+

+	--no-backup-mbr		do not copy the old MBR to the second sector of

+				DEVICE_OR_FILE.

+

+	--force-backup-mbr	force the copy of old MBR to the second sector

+				of DEVICE_OR_FILE.

+

+	--mbr-enable-floppy	enable the search for GRLDR on floppy.

+

+	--mbr-disable-floppy	disable the search for GRLDR on floppy.

+

+	--mbr-enable-osbr	enable the boot of PREVIOUS MBR with invalid

+				partition table(usually an OS boot sector).

+

+	--mbr-disable-osbr	disable the boot of PREVIOUS MBR with invalid

+				partition table(usually an OS boot sector).

+

+	--duce			disable the feature of unconditional entrance

+	                        to the command-line.

+

+				Normally one can unconditionally get the

+				command-line console by a keypress of `C',

+				bypassing all config-files(including the

+				preset-menu). This is a security hole. So we

+				need this option to disable the feature.

+

+				DUCE is for Disable Unconditional Command-line

+				Entrance.

+

+	--chs-no-tune		disable the feature of geometry tune.

+

+	--boot-prevmbr-first	try to boot PREVIOUS MBR before the search for

+				GRLDR.

+

+	--boot-prevmbr-last	try to boot PREVIOUS MBR after the search for

+				GRLDR.

+

+	--preferred-drive=D	preferred boot drive number, 0 <= D < 255.

+

+	--preferred-partition=P	preferred partition number, 0 <= P < 255.

+

+	--serial-number=SN	setup a new serial number for the hard drive.

+				SN must be non-zero.

+

+	--time-out=T		wait T seconds before booting PREVIOUS MBR. if

+				T is 0xff, wait forever. The default is 5.

+	

+	--hot-key=K		if the desired key K is pressed, start GRUB

+				before booting PREVIOUS MBR. K is a word

+				value, just as the value in AX register

+				returned from int16/AH=1. The high byte is the

+				scan code and the low byte is ASCII code. The

+				default is 0x3920 for space bar. See "int 16

+				keyboard scan codes" below.

+

+	--floppy		if DEVICE_OR_FILE is floppy, use this option.

+

+	--floppy=N		if DEVICE_OR_FILE is a partition on a hard

+				drive, use this option. N is used to specify

+				the partition number: 0,1,2 and 3 for the

+				primary partitions, and 4,5,6,... for the

+				logical partitions.

+

+	--sectors-per-track=S	specifies sectors per track for --floppy.

+				1 <= S <= 63, default is 63.

+

+	--heads=H		specifies number of heads for --floppy.

+				1 <= H <= 256, default is 255.

+

+	--start-sector=B	specifies hidden sectors for --floppy=N.

+

+	--total-sectors=C	specifies total sectors for --floppy.

+				default is 0.

+

+	--lba			use lba mode for --floppy. If the floppy BIOS

+				has LBA support, you can specify --lba here.

+				It is assumed that all floppy BIOSes have CHS

+				support. So you would rather specify --chs.

+				If neither --chs nor --lba is specified, then

+				the LBA indicator(i.e., the third byte of the

+				boot sector) will not be touched.

+

+	--chs			use chs mode for --floppy. You should specify

+				--chs if the floppy BIOS does not support LBA.

+				We assume all floppy BIOSes have CHS support.

+				So it is likely you want to specify --chs.

+				If neither --chs nor --lba is specified, then

+				the LBA indicator(i.e., the third byte of the

+				boot sector) will not be touched.

+

+	--fat12			FAT12 is allowed to be installed for --floppy.

+

+	--fat16			FAT16 is allowed to be installed for --floppy.

+

+	--fat32			FAT32 is allowed to be installed for --floppy.

+

+	--vfat			FAT12/16/32 are allowed to be installed for

+				--floppy.

+

+	--ntfs			NTFS is allowed to be installed for --floppy.

+

+	--ext2			EXT2 is allowed to be installed for --floppy.

+

+	--install-partition=I	Install the boot record onto the boot area of

+				partition number I of the specified hard drive

+				or harddrive image DEVICE_OR_FILE.

+

+DEVICE_OR_FILE:	Filename of the device or the image file. For DOS, a BIOS drive

+number(hex 0xHH or decimal DDD) can be used to access the drive. BIOS drive

+number 0 is for the first floppy, 1 is for the second floppy; 0x80 is for the

+first hard drive, 0x81 is for the second hard drive, etc.

+

+Note: BOOTLACE.COM writes only the boot code to MBR. The boot code needs to

+load GRLDR as the second(and last) stage of the GRUB boot process. Therefore

+GRLDR should be copied to the root directory of one of the supported

+partitions, either before or after a successful execution of BOOTLACE.COM.

+Currently only partitions with filesystem type of FAT12, FAT16, FAT32, NTFS,

+EXT2 or EXT3 are supported.

+

+Note 2: If DEVICE_OR_FILE is a harddisk device or a harddisk image file, it

+must contain a valid partition table, otherwise, BOOTLACE.COM will fail. If

+DEVICE_OR_FILE is a floppy device or a floppy image file, then it must contain

+a supported filesystem(i.e., either of FAT12/FAT16/FAT32/NTFS/EXT2/EXT3).

+

+Note 3: If DEVICE_OR_FILE is a floppy device or a floppy image file, and it

+was formated EXT2/EXT3, then you should specify --sectors-per-track and

+--heads explicitly.

+

+

+Important!! If you install GRLDR Boot Record to a floppy or a partition, the

+floppy or partition will boot solely grldr, and your original

+IO.SYS(DOS/Win9x/Me) and NTLDR(WinNT/2K/XP) will become unbootable. This is

+because the original boot record of the floppy or partition was overwritten.

+There is no such problem when installing GRLDR Boot Record onto the MBR.

+Update: Some NTLDR/IO.SYS/KERNEL.SYS files can be directly chainloaded in the

+latest GRUB4DOS.

+

+Tip: If the filename begins in a dash(-) or a digit, you may prefix a dirname

+(./) or (.\) to it.

+

+Examples:

+

+	Installing GRLDR boot code to MBR under Linux:

+

+		bootlace.com  /dev/hda

+kexec -l grub.exe --initrd=WIN98.IMG --command-line="--config-file=map (rd) (hd0); map --hook; chainloader (hd0)+1; rootnoverify (hd0)"

+

+kexec -e

+

+If DOS.IMG is a bootable floppy image, do this way:

+

+kexec -l grub.exe --initrd=DOS.IMG --command-line="--config-file=map (rd) (fd0); map --hook; chainloader (fd0)+1; rootnoverify (fd0)"

+

+kexec -e

+

+Note that in this manner, we can boot DOS/Win9x without using a real DOS/Win9x

+disk. We need no FAT partition but an image file.

+

+We have noticed that Linux itself can act as a big boot manager by using kexec

+and grub.exe. This may be convenient to developers who write installation or

+bootstrap or initialization programs.

+

+Certainly, grub.exe and the bootable disk image can also be loaded by a running

+GRUB or LILO or syslinux. Examples:

+

+1. Loaded by GRUB:

+

+	kernel (hd0,0)/grub.exe --config-file="map (rd) (fd0); map --hook; chainloader (fd0)+1; rootnoverify (fd0)"

+	initrd (hd0,0)/DOS.IMG

+	boot

+

+2. Loaded by LILO:

+

+	image=/boot/grub.exe

+		label=grub.exe

+		initrd=/boot/DOS.IMG

+		append="--config-file=map (rd) (fd0); map --hook; chainloader (fd0)+1; rootnoverify (fd0)"

+

+3. Loaded by SYSLINUX:

+

+	label grub.exe

+		kernel grub.exe

+		append initrd=DOS.IMG --config-file="map (rd) (fd0); map --hook; chainloader (fd0)+1; rootnoverify (fd0)"

+

+Note: If the above `map (rd) (...)' failed, you may use `map (rd)+1 (...)'

+instead and try again.

+        [1]   In the United States, the 101/102-key keyboard is shipped

+              with 101 keys. Overseas versions have an additional key

+              sandwiched between the left Shift key and the Z key. This

+              additional key is identified by IBM (and in this table) as

+              "Key 45."

+

+        [**]  Keys and key combinations marked ** are used by the ROM BIOS

+              but do not put values into the keyboard buffer.

+

+	- The PS/2 models have three make/break scan code sets.  The first

+	  set matches the PC & XT make/break scan code set and is the one

+	  listed here.	Scan code sets are selected by writing the value F0

+	  to the keyboard via the 8042 (port 60h).  The following is a brief

+	  description of the scan code sets (see the PS/2 Technical Reference

+	  manuals for more information on scan code sets 2 and 3):

+

+	/  set 1, each key has a base scan code.  Some keys generate

+	   extra scan codes to generate artificial shift states.  This

+	   is similar to the standard scan code set used on the PC and XT.

+	/  set 2, each key sends one make scan code and two break scan

+	   codes bytes (F0 followed by the make code).	This scan code

+	   set is available on the IBM AT also.

+	/  set 3, each key sends one make scan code and two break scan

+	   codes bytes (F0 followed by the make code) and no keys are

+	   altered by Shift/Alt/Ctrl keys.

+	/  typematic scan codes are the same as the make scan code

+

+	- Some Tandy 1000's do not handle Alt key combinations when multiple

+	  shift keys are pressed.  The Alt-Shift-H combination loses the Alt.

+	- extended keys like (F11, F12) can only be read with systems that

+	  have extended keyboard BIOS support (or INT 9 extensions);  to

+	  read these special keys on these systems INT 16,10 must be used

+

+***                         GRLDR  Error messages                          ***

+******************************************************************************

+

+1. Missing MBR-helper.

+

+	The helper function in the sectors that immediately follow the MBR is

+	not present, or it has been erased by a virus or by Windows XP/Vista.

+

+	Run the bootlace.com utility to fix the problem.

+

+2. Buggy BIOS!

+

+	Your BIOS is too buggy. It even has no support for INT13/AH=8.

+

+	No solution except flashing your BIOS. Buggy BIOSes will encounter

+	more and more problems with grub4dos in the future.

+

+3. This partition is NTFS but with unknown boot record. Please install

+Microsoft NTFS boot sectors to this partition correctly, or create an

+FAT12/16/32 partition and place the same copy of GRLDR and MENU.LST there.

+

+	The boot record was changed or erased by Microsoft Windows XP Service

+	Pack 2.

+

+	You may install the old boot record introduced with the	original clean

+	Windows 2K/XP. As another solution, you may create an FAT partition

+	for your system, and copy GRLDR and your MENU.LST to its root dir.

+

+	While the startup code of grldr might fail to load GRLDR in NTFS

+	partitions, it always successfully loads GRLDR in FAT partitions(and

+	even in ext2/ext3 partitions).

+

+	Note that NTLDR only loads the startup code of grldr(i.e., the leading

+	16 sectors of grldr), not the whole grldr file.

+

+	Thus, C:\GRLDR must exist(here C: can be NTFS), since it is used for

+	BOOT.INI and NTLDR. If C: is NTFS, X:\GRLDR should exist as well,

+	where X: stands for a certain FAT partition.

+******************************************************************************

+

+1. Some newer Dell machines have no int13/AH=43h support. You may encounter

+	failure when trying to write-access an emulated disk.

+

+	Note: This bug is serious! The old "root+setup" installation method

+	(in real mode grub environment) uses INT13 to write the first sector

+	of stage2. It will fail for the buggy DELL machine when stage2 is

+	accessed with LBA mode.

+

+2. Some buggy BIOSes won't boot bootable.iso(See above).(qemu can boot it fine)

+

+3. Some newer Dell machines violently destroyed the interrupt vectors for

+	hardware IRQs and will hang the machine when running GRUB.EXE

+	from DOS. You may try again with BADGRUB.EXE.

+

+4. Reports say some BIOSes will function abnormally after GRUB.EXE is started

+	by kexec of Linux. Some machines reportedly hang. Some others

+	reportedly cannot access USB drives.

+***                             Known Problems                             ***

+******************************************************************************

+

+1.	Running GRUB.EXE from a DOS box of Windows 9x/Me could hang the

+	machine, especially for some systems with USB support. You may

+	encounter the same problem when running GRUB.EXE through KEXEC under

+	Linux.

+

+Note:	You don't have to run GRUB.EXE from protected mode of Win9x, which

+	could hang the machine; Instead, you usually want to run GRUB.EXE

+	after you have done a "Restart the computer in MS-DOS mode", which

+	is safe enough.

+

+2.	The default chainloader action will keep A20 on. Some buggy DOS XMS

+	memory managers could hang the machine. You may use the --disable-a20

+	option in the chainloader line and try again. Anyway, you should avoid

+	using those buggy memory managers.

+

+3.	THTF BIOS L4S5M Ver 1.1a(dated 2002-1-10) has a buggy int15 which

+	causes hang at the boot of a multi boot kernel(memdisk for example).

+

+4.	A Chinese DOS system software, the TechWay SCS, will not work with

+	newer versions of GRUB.EXE. In general, TSRs that take antitracking

+	measures will not work with GRUB.EXE any more.

+

+Note: The GRUB file(WITHOUT .EXE suffix) is a static-linked ELF executable

+program for Linux, normally called the GRUB Shell. The GRUB Shell is a boot-

+manager, but not a boot-loader(the "boot" command won't work in GRUB Shell). 

+GRUB.EXE(with KEXEC) can be used as a bootloader running directly under Linux.

+

+******************************************************************************

+***             Memory Layout for Quiting to DOS from GRUB.EXE             ***

+******************************************************************************

+

+The quit command is implemented to return to DOS in the instance that GRUB.EXE

+is started off DOS.

+

+1. Before GRUB.EXE transfers control to pre_stage2, it will copy 640KB of

+conventional memory to physical address 0x200000(i.e., 2MB), and write 4 long

+integers immediately follows the backup copy of the conventional memory:

+	At 0x2A0000:	0x50554B42, it is the "BKUP" signature.

+

+	At 0x2A0004:	Gate A20 status under DOS: non-zero means A20 on;

+			zero means A20 off. Update: A20 always on, see below.

+

+	At 0x2A0008:	high word is boot-CS, low word is boot-IP. The quit

+			command uses this entry point to return to DOS.

+

+	At 0x2A000C:	CheckSum: the sum of all long integers in the memory

+			range from 0x200000 to 0x2A000F is 0.

+

+2. If the above memory structure is corrupted by a grub command, the quit

+command will issue an error message and refuse to exit from grub.

+

+3. Because GRUB may corrupt extended memory, you should better avoid using

+extended memory under DOS before running GRUB.EXE.

+

+4. Gate A20 will be enabled by GRUB.EXE. Hopefully this would hurt nothing.

+***                Command-line Length about GRUB.EXE                      ***

+******************************************************************************

+

+GRUB.EXE now can be started in CONFIG.SYS with the **DEVICE** command:

+

+	DEVICE=grub.exe [--config-file="FILENAME_OR_COMMANDS"]

+

+1. If GRUB.EXE is invoked with DEVICE command and FILENAME_OR_COMMANDS is a

+collection of some GRUB commands separated by semi-colon, then the length of

+FILENAME_OR_COMMANDS can be nearly 4KB ----Supprise? But true!  MS-DOS 7+

+even allows a much longer line, but 4KB seems enough for our use of GRUB.EXE.

+This is very useful when we want to embed a big menu into the command line.

+Note that GRLDR hasn't yet supported any command-line arguments.

+

+2. If GRUB.EXE is invoked with INSTALL command, the option length has a limit

+of 80 characters(including the leading "--config-file=" part). An overflow may

+hang up MS-DOS immediately.

+

+3. If GRUB.EXE is invoked with SHELL command, the option length has a limit of

+126 characters(including the leading "--config-file=" part). Overflow won't

+hang up MS-DOS, but the line will be cut short. This limit is the same as that

+in the console-DOS-prompt or in a BAT file.

+

+4. The DOS editor EDIT does not allow to create a line of 4KB long. So use

+another editor, for example, vi for Linux, please.

+

+5. The DEVICE=GRUB.EXE line can be used together with other DEVICE commands

+such as DEVICE=HIMEM.SYS and DEVICE=EMM386.EXE. The GRUB.EXE line should

+occur before the EMM386.EXE line in order to avoid the rejection by EMM386.

+Update: Since 0.4.2, GRUB.EXE works well even after EMM386.EXE is loaded.

+

+6. In any case mentioned above, you can return back to DOS by quit command.

+

+7. Memory usage about command-line menu: The 4KB command-line menu starts at

+physical address 0x0800 and ends at 0x17FF.

+

+******************************************************************************

+***          New Syntax for the DEFAULT/SAVEDEFAULT Commands               ***

+******************************************************************************

+

+In addition to the original usage of "default NUM" and "default saved", now

+there is a new usage of "default FILE", like this:

+

+		default (hd0,0)/default

+

+Note that FILE must have a valid DEFAULT file format. A sample DEFAULT file

+is included in the release. You may copy it to wherever you like, but you

+should avoid modifying its content manually. The DEFAULT file may be used

+in this way:

+

+(1) First, you should copy a default file with valid format to somewhere in

+your operating system.

+

+(2) Secondly, you should use the "default FILE" command of GRUB to announce

+the use of FILE as our new default file for being written by "savedefault".

+

+(3) Then, you may use "savedefault" command to save the desired entry number

+into this new default file.

+

+(4) OK, at next boot, you may read the saved entry number by using the same

+"default FILE" command as mentioned in above (2).

+

+And the SAVEDEFAULT command now accept an options `--wait=T', like this:

+

+		savedefault --wait=5

+

+If `--wait=T' is specified and T is non-zero, savedefault will prompt

+the user with a message just before it writes to disk. The write operation

+will be cancelled in T seconds if the `Y' key was not pressed.

+

+Here is a sample menu.lst file:

+

+Note 1:	The file DEFAULT must exist and have a proper format as stated above.

+	Or else, the default/savedefault commands won't function well.

+

+Note 2:	The file DEFAULT which is in the same dir as a certain MENU.LST file

+	is called associated with the MENU.LST file.

+

+Note 3:	The associated DEFAULT file will take effect automatically if there

+	are no `default' commands present.

+

+Note 4:	Just before a menu file gains control(e.g., it is the associated

+	MENU.LST of a GRLDR file, or it was specified via

+	`grub.exe --config-file=(DEVICE)/PATH/YOUR_MENU_FILE', or it was

+	specified by the `configfile' command of grub), its associated

+	DEFAULT file will be used if present, until an explicit `default'

+	command is encountered.

+***                   The New `cdrom' Command Syntax                       ***

+******************************************************************************

+

+1. Initialize the ATAPI CDROM devices:

+

+	grub> cdrom --init

+

+   This will display the number of atapi cdroms found: atapi_dev_count

+

+2. Stop the ATAPI CDROM devices:

+

+	grub> cdrom --stop

+

+   This will set atapi_dev_count to 0.

+

+3. Add IO ports for searching the atapi cdrom devices. For example:

+

+	grub> cdrom --add-io-ports=0x03F601F0

+

+After running `cdrom --init' and `map --hook', the cdroms can be accessed

+through devices (cd0), (cd1), ...

+

+Note 1: If the system does not fully support the ATAPI CD-ROM specifications,

+	you will encounter failure when trying to access the (cdX) devices.

+

+Note 2: After doing a `cdrom --stop', you should do a `map --unhook'. Of

+	course you may `map --hook' again if there are mapped drives.

+

+Note 3: After adding IO ports, you should do a `map --unhook' followed by a

+	`cdrom --init' and then followed by a `map --hook'.

+

+	By default, these ports are used for searching cdroms(so they needn't

+	be added):

+

+		0x03F601F0, 0x03760170, 0x02F600F0,

+		0x03860180, 0x6F006B00, 0x77007300.

+

+Note 4: The BIOS might have offered a cdrom interface. It would be (cd). After

+	`cdrom --init' and `map --hook', we might have our (cd0), (cd1), ...

+	available. It is likely that one of them could access the same media

+	as the BIOS-offered (cd).

+

+Note 5: You may access the (cd) and (cdX)'es in the blocklist way. Example:

+

+		cat --hex (cd0)16+2

+

+	The cdrom sectors are big sectors with a size of 2048 bytes.

+

+Note 6:	The iso9660 filesystem driver has Rock-Ridge extension support, but

+	has no Joliet extension support. So you may encounter failure when

+	you attempt to read files on a Joliet CD.

+

+Note 7: The (cd) or (cdX)'es can be booted now. Examples:

+

+		chainloader (cd)

+		boot

+

+		chainloader (cd0)

+		boot

+

+		chainloader (cd1)

+		boot

+

+	You should already have access to the CD sectors before you can

+	chainload it.

+***                   About the New `setvbe' Command                       ***

+******************************************************************************

+

+Gerardo Richarte contributed the `setvbe' code and the following comment:

+

+	New command is `setvbe', and can be used to change the video mode

+	before executing the kernel.

+

+	For example, you can do

+

+		setvbe 1024x768x32

+

+	this will scan the list of available modes and set it, and

+	automatically append a `video=' option to each subsequent kernel

+	command-line. The appended `video=' option is like this:

+

+		video=1024x768x32@0xf0000000,4096

+

+	where 0xf0000000 is the video framebuffer address as reported by vbe,

+	and 4096 is the size of a scanline in bytes (also as reported by vbe).

+

+	This is really useful if you want to give some graphics support to your

+	OS, but you don't want to implement any video functionality other than

+	writing a pixel to video memory.

+***                   About the DOS utility `hmload'                       ***

+******************************************************************************

+

+This program was written by John Cobb (Queen Mary, University of London).

+

+John Cobb's note:

+

+	To make use of the ram drive feature I wrote a program `hmload' to load

+	an arbitrary file to an arbitrary address in high memory. The program

+	is not very sophisticated and relies on XMS to turn on the A20 line.

+	(Also one must be very careful to steer clear of any areas of memory

+	already in use).

+

+	Under Linux we generated a disk image `dskimg' (with the kernel and

+	Initrd and a partition table).

+

+	Using this our boot procedure looked something like this:

+

+	hmload -fdskimg -a128

+	fixrb

+	<unload network drivers>

+	grub

+

+		map --ram-drive=0x81

+		map --rd-base=0x8000000

+		map --rd-size=0x400000

+		root (rd,0)

+		kernel /kernel root=/dev/ram0 rw ip=bootp ramdisk_size=32768 ...

+		initrd /initrd

+		boot

+

+See http://sysdocs.stu.qmul.ac.uk/sysdocs/Comment/GrubForDOS/ for details.

+

+Update 2007-12-05:

+

+	Now the MAP command can handle gzipped (rd) image. One can use this

+	feature with the hmload utility. For example,

+

+	step 1. Load the gzipped image under DOS at a relatively low address:

+

+		hmload -fdskimg.gz -a16

+

+	step 2. Unload network drivers.

+

+	step 3. Run GRUB.EXE.

+

+	step 4. At the grub prompt, run these commands:

+

+		map --rd-base=0x1000000	# set rd-base address to be 16M

+		map --rd-size=<the accurate size of dskimg.gz in bytes>

+		map (rd)+1 (hd0)	# This will decompress (rd) and place

+					# the decompressed image at the top end

+					# of the extended memory. The (rd)+1

+					# here has special meaning and stands

+					# for the whole (rd) device. You must

+					# use (rd)+1 instead of (rd).

+		map --hook

+		root (hd0,0)

+		kernel /kernel root=/dev/ram0 rw ip=bootp ramdisk_size=32768 ...

+		initrd /initrd

+		map --unhook

+		map (hd0) (hd0)		# Delete the map; this is needed.

+		boot

+***                      Notes on the use of stack                         ***

+******************************************************************************

+

+The protected-mode and real-mode stack are merged at physical address 0x2000.

+

+All functions should use at most 2K stack space(0x1800-0x2000). So each

+subfunction should use as little stack as possible to avoid stack-overflow.

+

+Don't use recursive functions because they could expend too much stack space.

+

+The original protected mode stack at 0x68000(expand-down) is free now and can

+be reused for any purposes.

+

+

+******************************************************************************

+***                  A bug was found in the CDROM driver                   ***

+******************************************************************************

+

+It seems the cdrom must be connected as the master device of an IDE controller.

+

+If cdrom is slave, the driver will fail to read the cdrom sectors. Hope someone

+

+could fix this problem.

+***                        BIOS and the (cd) drive                         ***

+******************************************************************************

+

+When BIOS boots a no-emulation-mode bootable CD-ROM, it allocates a BIOS drive

+number to the CD. If the boot image of the CD-ROM is grldr or stage2_eltorito,

+then GRUB can access the CD-ROM media through the drive number allocated by

+BIOS. The device name of the CD-ROM is (cd).

+

+BIOS can allocate a BIOS drive number to a no-emulation-mode CDROM even when

+the CDROM is not bootable. QEMU has done so. At boot time, GRUB4DOS will

+search drives 0x80-0xFF for a possible no-emulation-mode CDROM drive allocated

+by BIOS. So if BIOS offered a CDROM interface of int13 EBIOS functions 41h-4Eh,

+then the (cd) device will be automatically available in GRUB4DOS.

+

+

+******************************************************************************

+***              The way of disk emulation changed greatly                 ***

+******************************************************************************

+

+The way of disk emulation has changed greatly since 0.4.2 final. Please don't

+mix newer versions with older versions when disk emulation features are used.

+

+The newer versions won't automatically unhook emulations established in a

+previous grub4dos environment. The GRUB.EXE of an older version will

+automatically dismiss emulations established earlier, before transferring

+control to the main grub program(i.e., pre_stage2).

+******************************************************************************

+

+The VCPI function "AX=DE0Ch - Switch From Protected Mode to V86 Mode" of

+FreeDOS EMM386 v2.26 was not implemented properly(it always hangs). As an

+alternative, you can use Microsoft's EMM386 instead.

+

+Even while emm386 is running, grub.exe can be started. But if you try to quit

+to DOS from grub4dos by using the `quit' command, the VCPI function DE0C will

+be called. If EMM386 is of Microsoft, everything goes ok. If EMM386 is of

+FreeDOS, the machine will hang.

+

+

+******************************************************************************

+***                 New options for map were added                         ***

+******************************************************************************

+

+Along with 0.4.2 final, there are two new options for the map command. They

+are --safe-mbr-hook=SMH and --int13-scheme=SCH. Both are related with disk

+emulation for use(as smoothly as possible) in the Win9x environment.

+

+SMH can take either of the two values 0 and 1. By default, SMH is 1. If you

+encountered problems of disk emulation under Win9x, you may insert a line of

+

+	map --safe-mbr-hook=0

+

+before the `boot' command and try again.

+

+Also SCH may take either 0 or 1 at present. By default, SCH is 1. If you

+encountered disk emulation problems under Win9x, you may insert a line of

+

+	map --int13-scheme=0

+

+before the `boot' command and try again.

+

+Note by the way. Like --safe-mbr-hook and --int13-scheme, the MAP command has

+a few other options that are used for setting global variables. They are here:

+

+	map --floppies=M

+

+M can be 0, 1, or 2. MAP will set a proper value at 0040:0010 by using M.

+

+	map --harddrives=N

+

+N can be between 0 and 127(inclusive). MAP will set 0040:0075 to N.

+

+	map --memdisk-raw=RAW

+

+RAW default to 1. If RAW=0, `int15/ah=87h' will be used to access memdrives.

+

+	map --ram-drive=RD

+

+RD default to 0x7F which is a floppy. If the RAM DRIVE is a hard drive image

+(with partition table in the first sector), you should set RD >= 0x80 and RD

+< 0xFF.

+

+	map --rd-base=ADDR

+

+	map --rd-size=SIZE

+

+ADDR specifies the physical base address of the ramdisk image. SIZE specifies

+the size in bytes of the ramdisk image. ADDR default to 0. SIZE is also default

+to 0, but a size of 0 means 4GB, not a zero-long disk. The RAM DRIVE can be

+accessed in the GRUB environment using the (rd) device.

+

+***                   About the new map option --in-situ                   ***

+******************************************************************************

+

+--in-situ is used with hard drive images or hardrive partitions. With an

+in-situ map, we can typically use a logical partition as a primary partition.

+

+In-situ map is a whole drive map. It only virtualize the partition table and

+the number of hidden sectors in the BPB of the DOS Boot Record.

+

+While disk emulation may encounter various problems with win9x, the in-situ map

+works fine with win9x.

+

+Note that --in-situ will not change the real partition table.

+

+Example:

+

+	map --in-situ (hd0,4)+1 (hd0)

+

+

+******************************************************************************

+***                      The PARTNEW Command Syntax                        ***

+******************************************************************************

+

+Besides the mappings in the above section, you may instead choose to create a

+new primary partition with the PARTNEW command. PARTNEW can generate a primary

+partition entry (in the partition table) for a logical partition.

+

+For example,

+

+	partnew (hd0,3) 0x07 (hd0,4)+1

+

+where the file (hd0,4)+1 stands for the whole partition (hd0,4). This command

+will create a new primary partition (hd0,3) whose type is 0x07 and whose

+contents/data is the same as that of the logical partition (hd0,4).

+

+Just like a whole logical partition, a contiguous partition image file can

+also be used with PARTNEW:

+

+	partnew (hd0,3) 0x00 (hd0,0)/my_partition.img

+

+The type 0x00 indicates a type-auto-detection of the image MY_PARTITION.IMG.

+The above command will create a new primary partition (hd0,3) with a proper

+type and with contents/data being exactly that of the contiguous file

+(hd0,0)/my_partition.img.

+

+PARTNEW will automatically correct the "hidden sectors" in the BPB and the

+modification will be permanent. And PARTNEW modifies the partition table

+permanently.

+

+In addition to creating new partition entries, PARTNEW can also be used to

+delete(erase, or wipe) a primary partition entry. For example,

+

+	partnew (hd0,3) 0 0 0

+

+which will empty the last entry in the partition table in MBR. Generally,

+you should use the form of "partnew PARTITION 0 0 0" to erase the entry.

+Note that only the entry would be erased, and the data stored in the partition

+will not be touched.

+***              Newly implemented operators `&&' and `||'                 ***

+******************************************************************************

+

+This implementation is very simple. It does not handle operator nesting.

+

+Usage of `&&':

+

+	command1 && command2

+

+Description:

+

+	If command1 returns true, then command2 will be executed.

+

+Usage of `||':

+

+	command1 || command2

+

+Description:

+

+	If command1 returns false, then command2 will be executed.

+

+Examples:

+

+	is64bit && default 0

+	is64bit || default 1

+

+******************************************************************************

+***          Three new commands is64bit, errnum and errorcheck             ***

+******************************************************************************

+

+is64bit and errnum retrieve the value of is64bit and errnum respectively.

+

+errorcheck controls whether or not the error will be handled. By default,

+errorcheck is on, and menu script execution will stop on error. If errorcheck

+is off, the script will continue to execute upto a boot command. A boot command

+will turn the errorcheck on.

+

+

+******************************************************************************

+***              Use numeric keys to select a menu entry                   ***

+******************************************************************************

+

+If, for example, you intend to goto entry #25, you may press 2 followed by 5.

+

+

+******************************************************************************

+***           Use the INSERT key to debug step by step at startup          ***

+******************************************************************************

+

+Some buggy machines could fail to enter grub4dos environment. They might hang

+or reboot unexpectedly. Press INSERT as quickly as possible on startup, and

+you can get a chance to single-step the boot process and see how far it can

+go, and then report bugs.

+

+

+******************************************************************************

+***             The debug command syntax has been changed                  ***

+******************************************************************************

+

+The DEBUG command now can be used to control the verbosity of command output:

+

+		debug [ on | off | normal | status | INTEGER ]

+

+0 or off for silent

+1 or normal for normal

+2 to 0x7FFFFFFF or on for verbose

+

+******************************************************************************

+***                     GRUB4DOS and Windows Vista                         ***

+******************************************************************************

+

+First, use the following command to create a boot entry:

+

+	bcdedit /create /d "GRUB for DOS" /application bootsector

+

+The result will look like this:

+

+The entry {05d33150-3fde-11dc-a457-00021cf82fb0} was successfully created.

+

+The long string {05d33150-3fde-11dc-a457-00021cf82fb0} is the id for this

+entry.

+

+Then, use the following commands to set boot parameters:

+

+	bcdedit /set {id} device boot

+	bcdedit /set {id} path \grldr.mbr

+	bcdedit /displayorder {id} /addlast

+

+Please replace {id} with the actual id returned from the previous command.

+

+Finally, copy GRLDR.MBR to C:\ or wherever your boot drive is, and copy GRLDR

+and menu.lst to the root directory of any FAT16/FAT32/EXT2/NTFS partition.

+

+Note: A boot partition should be the active primary partition with BOOTMGR

+      inside. The `device boot' indicates grldr.mbr should be in the boot

+      partition.

+

+Lianjiang has written down a script to automate the tasks:

+

+	@echo off

+	rem by lianjiang

+	cls

+	echo.

+	echo   Please run as administrator

+	echo.

+	pause

+	set gname=GRUB for DOS

+	set vid=

+	set timeout=5

+	bcdedit >bcdtemp.txt

+	type bcdtemp.txt | find "\grldr.mbr" >nul && echo. && echo  BCD entry existing, no need to install. && pause && goto exit

+	bcdedit  /create /d "%gname%" /application bootsector >vid.ini

+	for,/f,"tokens=2 delims={",%%i,In (vid.ini) Do (

+                  set vida=%%i

+	echo.

+	echo   Please copy grldr.mbr to %systemdrive%\

+	echo.

+	pause

+	:exit

+	del bcdtemp.txt >nul

+-------------------------------------------------------------------

+Update: Fujianabc pointed out that

+

+	bcdedit  /set %vid% device boot >nul

+

+should be changed to

+

+	bcdedit  /set %vid% device partition=%SystemDrive% >nul

+-------------------------------------------------------------------

+

+You still need to copy grldr yourself.

+

+Notice: It's possible to modify the BCD entry from a different OS, you just

+need to specify the location of BCD:

+

+	bcdedit /store D:\boot\BCD ...

+

+Notice: These commands need elevated privileges, they should be used inside

+cmd.exe which is started with "Run as administrator".

+

+Notice: People has reported that some version of Vista doesn't support

+creating file in C:\ with no extension, even with administrator privileges.

+This means grldr can't be placed in C:\. You can solve this by either copy

+grldr to another partition, or rename grldr to something like grub.bin. Please

+see the following section on how to do this.

+

+

+******************************************************************************

+***                      How to rename grldr                               ***

+******************************************************************************

+

+grldr and grldr.mbr use internal boot file name to decide which file to load,

+so if you want to change the name, you must also change the embeded setting.

+You can do this with the help of grubinst, which can be downloaded at:

+

+http://download.gna.org/grubutil/

+

+grubinst can generate customized grldr.mbr:

+

+	grubinst -o -b=mygrldr C:\mygrldr.mbr

+

+grubinst can also edit existing grldr/grldr.mbr:

+

+	grubinst -e -b=mygrldr C:\mygrldr

+

+	grubinst -e -b=mygrldr C:\mygrldr.mbr

+

+In this case, you must use a grubinst that is compatible with the version of

+grub4dos, otherwise the edit will fail.

+

+So, in order to load mygrldr instead of grldr, you can use one of the

+following methods:

+

+1. Use customized grldr.mbr to load mygrldr. In this case, you need to change

+the embeded boot file name in grldr.mbr. The name of grldr.mbr can be changed

+at will.

+

+2. Use mygrldr directly. In this case, you need to change the embeded boot

+file name in mygrldr to match its new name.

+

+Notice: The boot file name must conform to the 8.3 naming convention.

+***                          PXE device                                    ***

+******************************************************************************

+

+If PXE service is found at startup, GRUB4DOS will create a virtual device

+(pd), through which files from the tftp server can be accessed. You can setup

+a diskless boot environment using the following steps:

+

+Client side

+

+You need to boot from PXE ROM.

+

+Server side

+

+You need to configure a dhcp server and a tftp server. In the dhcp server, use

+grldr as boot file.

+

+You may also want to load a different menu.lst for different client. GRUB4DOS

+will scan the following location for configuration file:

+

+	[/mybootdir]/menu.lst/01-88-99-AA-BB-CC-DD

+	[/mybootdir]/menu.lst/C000025B

+	[/mybootdir]/menu.lst/C000025

+	[/mybootdir]/menu.lst/C00002

+	[/mybootdir]/menu.lst/C0000

+	[/mybootdir]/menu.lst/C000

+	[/mybootdir]/menu.lst/C00

+	[/mybootdir]/menu.lst/C0

+	[/mybootdir]/menu.lst/C

+	[/mybootdir]/menu.lst/default

+

+Here, we assume the network card mac for the client machine is

+88:99:AA:BB:CC:DD, and the ip address is 192.0.2.91 (C000025B). /mybootdir is

+the directory of the boot file, for example, if boot file is /tftp/grldr, then

+mybootdir=tftp.

+

+If none of the above files is present, grldr will use its embeded menu.lst.

+

+This is a menu.lst to illstrate how to use files from the tftp server.

+

+	title Create ramdisk using map

+	map --mem (pd)/floppy.img (fd0)

+	map --hook

+	rootnoverify (fd0)

+	chainloader (fd0)+1

+

+	title Create ramdisk using memdisk

+	kernel (pd)/memdisk

+	initrd (pd)/floppy.img

+

+You can see that the menu.lst is very similar to normal disk boot, you just

+need to replace device like (hd0,0) with (pd).

+

+There are some differences between disk device and pxe device:

+

+1. You can't list files in the pxe device.

+

+2. The blocklist command will not work with a file in the pxe device.

+

+3. You must use --mem option if you want to map a file in the pxe device.

+

+When you use chainloader to load file from the pxe device, there is a option

+you can use:

+

+	chainloader --raw (pd)/BOOT_FILE

+

+Option --raw works just like --force, but it load file in one go. This can

+improve performance in some situation.

+

+You can use the pxe command to control the pxe device.

+

+1. pxe

+

+	If used without any parameter, pxe command will display current

+	settings.

+

+2. pxe blksize N

+

+	Set the packet size for tftp transmission. Minimum value is 512,

+	maximum value is 1432. This parameter is used primarily for very old

+	tftp server where packet larger than 512 byte is not supported.

+

+3. pxe basedir /dir

+

+	Set the base directory for files in the tftp server. If

+

+		pxe basedir /tftp

+

+	then all files in the pxe device is related to directory /tftp, for

+	example, (pd)/aa.img correspond to /tftp/aa.img in the server.

+

+	The default value of base directory is the directory of the boot file,

+	for example, if boot file is /tftp/grldr, then default base directory

+	is /tftp.

+

+4. pxe keep

+

+	Keep the PXE stack. The default behaviour of GRUB4DOS is to unload

+	the PXE stack just before it exits.

+

+5. pxe unload

+

+	Unload the PXE stack immediately.

+******************************************************************************

+

+Use the `root' or `rootnoverify' command to specify the `working directory'.

+

+For example:

+

+		root  (hd0,0)/boot/grub

+

+This specifies that the working dir is (hd0,0)/boot/grub. So all subsequent

+filenames of the form "/..." will actually refer to (hd0,0)/boot/grub/...

+

+That is to say:

+

+		cat  /menu.lst

+

+will be equivalent to

+

+		cat  (hd0,0)/boot/grub/menu.lst

+

+

+

+******************************************************************************

+***                 Notation For The Current Root Device                   ***

+******************************************************************************

+

+

+The notation `()' can be used to access the current root device. You may use

+`find --set-root ...' to set the current root device, but the find command

+does not set the `working dir' of the root device. In this case you should

+use `()' to set the working dir after the find command:

+

+		root  ()/boot/grub

+

+Update 2008-05-01:

+

+	FIND can also set the `working directory' now. For example:

+

+		find  --set-root=/tmp  /boot/grub/menu.lst

+

+	It is equivalent to this pair of commands:

+

+		find  --set-root  /boot/grub/menu.lst

+		root  ()/tmp

+******************************************************************************

+

+

+Along with 0.4.3 final, map has a new option --a20-keep-on which is related to

+A20 control after a memdrive sector access. Usage:

+

+	map --a20-keep-on=0

+

+It should be used before the "map --hook" command.

+

+By default, A20 will be always on after an RAM INT13 sector access. If

+"map --a20-keep-on=0" is used, the A20 status after the INT13 call will be the

+same as that before the INT13 call.

+***                  The CDROM emulation (virtualization)                  ***

+******************************************************************************

+

+The CDROM emulation is sometimes called ISO emulation. Here is an example:

+

+	map  (hd0,0)/myiso.iso  (hd32)

+	map  --hook

+	chainloader  (hd32)

+	boot

+

+if myiso.iso is not contiguous and you have enough memory, add a --mem option:

+

+	map  --mem  (hd0,0)/myiso.iso  (hd32)

+	map  --hook

+	chainloader  (hd32)

+	boot

+

+Note: (hd32) is a grub drive number equivalent to (0xA0). If a virtual drive is

+specified with a drive number greater than or equal to 0xA0, then it will be

+treated as a cdrom (i.e., with 2048-byte big sectors).

+

+Like normal disk emulations, the CDROM emulation also (mainly) works with

+real-mode OSes. After a protected-mode OS kernel (such as

+WinNT/2K/XP/VISTA/LINUX) gains control, the OS would have no ability to access

+the virtual CDROM through BIOS int13.

+

+DOS/Win9x users may google for ELTORITO.SYS and use it in CONFIG.SYS as a

+device driver for the virtual cdrom.

+

+Example usage of eltorito.sys in CONFIG.SYS:

+

+	device=eltorito.sys /D:oemcd001

+

+Corresponding MSCDEX command which can be placed in AUTOEXEC.BAT:

+

+	MSCDEX /D:oemcd001 /L:D

+

+

+Due to some bugs found in eltorito.sys, the driver could fail to load. If you

+encounter such problems, then you may replace (hd32) with (0xFF) for the

+virtual cdrom drive number and try again.

+***                  The New Command CHECKRANGE                            ***

+******************************************************************************

+

+Checkrange checks whether or not the return value of a command is in the

+specified range or ranges.

+

+Usage:		checkrange  RANGE  COMMAND

+

+Here are some examples for RANGE:

+

+	3 is a range containing only the number 3

+	3:3 is equivalent to 3

+	3:8 is a range containing the numbers 3, 4, 5, 6, 7, 8

+	3,4,5,6,7,8 is equivalent to 3:8

+	3:5,6:8 is also equivalent to 3:8

+	3,4:7,8 is also equivalent to 3:8

+

+Note: You should not insert spaces into a range.

+

+Here is an example showing where the checkrange can be used:

+

+	checkrange 0x05,0x0F,0x85 parttype (hd0,1) || hide (hd0,1)

+

+which means: if (hd0,1) is not an extended partition, then hide it.

+

+The "tpm --init" uses 512-byte data at 0000:7C00 as buffer to initialise TPM.

+

+Before you boot VISTA's BOOTMGR, you might have to use the "tpm --init"

+***               Delimitors or comments between titles                    ***

+******************************************************************************

+

+It is possible to use titles as delimitors or comments. A title(or menu item)

+is called unbootable if all of its menu commands are not boot-sensitive.

+

+The following commands are boot-sensitive(and others are not boot-sensitive):

+

+	boot

+	bootp

+	chainloader

+	configfile

+	embed

+	commandline

+	halt

+	install

+	kernel

+	pxe

+	quit

+	reboot

+	setup

+

+An unbootable title will be skipped when the user presses the Up Arrow or Down

+Arrow keys. Even the unbootable menu item can get accessed(and executed) by

+using the Left Arrow and/or Right Arrow keys. Examples:

+

+	title This is an UNBOOTABLE entry(so this line is also a comment)

+		pause --wait=0 This title is a comment. Nothing to do.

+		pause --wait=0 You can use non-boot-sensitive commands here

+		pause --wait=0 of any kind and as many as you would like.

+		help

+		help root

+		help chainloader

+		help parttype

+		clear

+***                           Bifurcate drives                             ***

+******************************************************************************

+

+Some machines apply different actions to a drive between CHS and LBA mode.

+When you read sectors using standard BIOS call int13/AH=02h, you might find

+out the drive is a floppy. But when you read sectors using extended BIOS

+call(EBIOS) int13/AH=42h, you could know the drive is a cdrom. Such a drive

+is called bifurcate.

+

+A bifurcate drive can have two drive numbers: one is the normal BIOS drive

+number between 00 and FF in hexa, and this drive uses only CHS mode disk

+access(standard BIOS int13/AH=02h); the other is the normal BIOS drive number

+(Bitwise) OR'ed by 0x100(i.e., 256 in decimal), and this drive uses only

+LBA mode disk access(EBIOS int13/AH=42h). For example, if the drive 0x00

+(i.e., the first floppy) is bifurcate, then the drive (0x00) uses CHS mode

+to access its sectors, and the drive (0x100) uses LBA (meaning EBIOS) mode

+to access its sectors.

+

+The geometry command can report the disk access mode for bifurcate drives as

+BIF instead of the conventional CHS or LBA.

+

+Known bifurcate drives. Virtual PC and some real machines are found to create

+a bifurcate floppy drive when they boot from a floppy-emulation mode bootable

+cdrom. The "geometry (fd0)" will show

+

+	drive 0x00(BIF): C/H/S=...Sector Count/Size=.../512

+

+and "geometry (0x100)" will show

+

+	drive 0x100(BIF): C/H/S=...Sector Count/Size=.../2048

+

+Actually (0x100) can access the whole cdrom, you may "ls (0x100)/" and find

+your files on the cdrom(not the files inside the booted floppy image). Of

+course "ls (fd0)/" will list the files inside the booted floppy image.

+

+Note that only some (real or virtual) machines have this action, others

+will not produce bifurcate drives.

+***                       GRLDR as PXE boot file                           ***

+******************************************************************************

+

+GRLDR can be used as the PXE boot file on a remote/network server. The (pd)

+device is used to access files on the server. When GRLDR is booted through

+network, it will use its preset menu as the config file. However, you may use

+a "pxe detect" command, which acts the same way as PXELINUX:

+

+    * First, it will search for the config file using the hardware type (using

+      its ARP type code) and address, all in hexadecimal with dash separators;

+      for example, for an Ethernet (ARP type 1) with address 88:99:AA:BB:CC:DD

+      it would search for the filename 01-88-99-AA-BB-CC-DD. 

+

+    * Next, it will search for the config file using its own IP address in

+      upper case hexadecimal, e.g. 192.0.2.91 -> C000025B. If that file is not

+      found, it will remove one hex digit and try again. At last, it will try

+      looking for a file named default (in lower case). As an example, if the

+      boot file name is /mybootdir/grldr, the Ethernet MAC address is

+      88:99:AA:BB:CC:DD and the IP address 192.0.2.91, it will try following

+      files (in that order): 

+

+       /mybootdir/menu.lst/01-88-99-AA-BB-CC-DD

+       /mybootdir/menu.lst/C000025B

+       /mybootdir/menu.lst/C000025

+       /mybootdir/menu.lst/C00002

+       /mybootdir/menu.lst/C0000

+       /mybootdir/menu.lst/C000

+       /mybootdir/menu.lst/C00

+       /mybootdir/menu.lst/C0

+       /mybootdir/menu.lst/C

+       /mybootdir/menu.lst/default

+

+You cannot directly map an image file on (pd). You must map it in memory using

+the --mem option. For example,

+

+	map --mem (pd)/images/floppy.img (fd0)

+	map --hook

+	chainloader (fd0)+1

+	rootnoverify (fd0)

+	boot

+

+One more example,

+

+	map --mem (pd)/images/cdimage.iso (0xff)

+	map --hook

+	chainloader (0xff)

+	boot

+***           Use bootlace.com to install partition boot record            ***

+******************************************************************************

+

+Since bootlace.com has not implemented the --install-partition option, you

+need to use the already implemented --floppy=PartitionNumber option instead.

+

+Hear is a way you might want to follow:

+

+Step 1. Get the boot sectors of the partition and save to a file MYPART.TMP.

+	For NTFS, you need to get the beginning 16 sectors. For other type of

+	filesystems, you only need to get one sector, but getting more sectors

+	is also ok.

+

+Step 2. Run this:

+

+	bootlace.com --floppy=Y --sectors-per-track=S --heads=H --start-sector=B --total-sectors=C --vfat --ext2 --ntfs MYPART.TMP

+

+	where we suppose MYPART.TMP is for (hdX,Y) and the partition number Y

+	should be specified as in the --floppy=Y option.

+

+	Note that for FAT12/16/32/NTFS partitions, you can omit these options:

+

+		 --sectors-per-track, --heads, --start-sector, --total-sectors,

+		 --vfat and --ext2.

+

+	For NTFS partitions, you must specify --ntfs option.

+

+	For ext2 partitions, you can omit --vfat, --ntfs and --ext2 options,

+	but other options should be specified.

+

+Step 3. Put MYPART.TMP back on to the boot sector(s) of your original partition

+	(hdX,Y).

+

+

+Note: Only a few file systems(FAT12/16/32/NTFS/ext2/ext3) are supported by now.

+

+Note2: Under Linux you may directly write the partition. That is to say, Step

+	1 and Step 3 are not needed. Simply use its device name instead of

+	MYPART.TMP.

+

+Note3: grubinst has the feature of installing grldr boot code onto a

+	partition boot area.

+***                Use a single key to select menu item                    ***

+******************************************************************************

+

+Some machines have a simplified keyboard. The keyborad might have only the

+number keys 0 .. 9 plus a few other keys. When the menu displayed, the user

+can strike a key for 8 times. When the menu handler detects the continuous

+single keypress, it will assume the user want to use this key to select a menu

+item and boot. This single key will act as the RIGHT-ARROW key for the user to

+select a menu item. And 5 seconds later after the user stops the keypress,

+the selected menu item will automatically boot. Any normal keys can be used as

+a single key for this purpose, except for a few functional keys like b, e,

+Enter, etc. Once another key is pressed, the feature of Single-Key-Selection

+will disappear immediately.

+******************************************************************************

+

+You may move all or part of the command-line arguments into a file. The file

+can have multi lines. Just like SPACEs and TABs, the CRs and LFs can also

+delimit the commandline arguments in the parameter file.

+

+Example:

+

+		bootlace < my_parafile

+		bootlace --read-only my_mbr < my_other_options

+

+Note:	Pipes do not work. You have to use the input-redirection operator(<).

+

+

+******************************************************************************

+***                  Use bootlace to create a triple MBR                   ***

+******************************************************************************

+

+This is typically used for USB drives, though it also works with hard drives.

+

+Steps to create triple MBR:

+

+1. Do a fresh FDISK to create a FAT12/16/32 partition starting at sector 95

+(in LBA, that is, the begginning sector(MBR) is sector 0).

+

+2. Install grldr boot sector onto the boot sector of this partition. See

+section "Use bootlace.com to install partition boot record" above.

+

+3. Get 96 sectors of the drive starting at sector 0(MBR), and save to file

+MYMBR96.TMP.

+

+4. Run bootlace.com:

+

+	bootlace.com MYMBR96.TMP

+

+5. Put MYMBR96.TMP back onto the drive starting at MBR(sector 0).

+

+Note: If the drive already has a triple MBR, then bootlace will cancel it

+and restore the original partition layout.

+

+

+******************************************************************************

+***                    Use 'pxe detect' in preset-menu                     ***

+******************************************************************************

+

+Now the "pxe" command has a new subcommand "detect":

+

+		pxe detect [BLOCK_SIZE] [MENU_FILE]

+

+BLOCK_SIZE specifies the block size for PXE. If it is not specified or it is

+0, then grub4dos will go through a probing process and get a proper value

+for data transfer.

+

+MENU_FILE specifies the config file on the PXE server. If omitted, a standard

+config file in the menu.lst sub-dir will gain control. For a description on

+the config files in the menu.lst sub-dir, please refer to the section

+"GRLDR as PXE boot file" above.

+If MENU_FILE starts in a "/", then the MENU_FILE on the PXE server will gain

+control, else(if MENU_FILE does not start in a "/") no menu will be executed.

+

+Normally you want to use a "pxe blksize ..." or a "pxe detect ..." command

+before you access the (pd) device, since the default blocksize of 512 might

+not work on your system.

+

+

+******************************************************************************

+***                    Use 'configfile' in preset-menu                     ***

+******************************************************************************

+

+Now the preset menu holds the highest priority. It will gain control prior to

+the menu.lst on the boot device. If a 'configfile' command(without specifying

+any file as the parameter) occurs in the menu init command group of the preset

+menu, then control will go to the menu.lst on the boot device.

+

+Note: You should better not use "configfile ANOTHER_MENU" frequently in your

+menu.lst file, because it could create infinite loop and thus hang your

+computer.

+***                    New command 'dd' to copy files                      ***

+******************************************************************************

+

+Usage:

+

+dd if=IF of=OF [bs=BS] [count=C] [skip=IN] [seek=OUT] [buf=ADDR] [buflen=SIZE]

+

+Copy file IF to OF. BS is blocksize in bytes, default to 512. C is blocks to

+copy, default is total blocks in IF. IN specifies number of blocks to skip

+when read, default is 0. OUT specifies number of blocks to skip when write,

+default is 0. Skipped blocks are not touched. Both IF and OF must exist.

+

+Both IF and OF must have a leading device name, i.e.,  of the form `(...)'.

+You may use `()' for the current root device.

+

+dd can neither enlarge nor reduce the size of OF, the leftover tail of IF

+will be discarded. OF cannot be a gzipped file. If IF is a gzipped file,

+it will be decompressed automatically when copying.

+

+dd is dangerous, use at your own risk. To be on the safe side, you should

+only use dd to write a file in memory.

+

+In some cases when writing a file in a NTFS volume, dd might fail.

+

+If you attempt to write a device or a block file that is not in memory by

+starting dd in a menu, you will safely be refused :-) (Update: no restrictions

+now)

+

+Update: New options are implemented for user defined buffer. By default,

+the buffer is at address 0x50000, and length is 0x10000(=64KB). You cannot

+specify ADDR to be lower than 0x100000(=1MB). Besides, you must specify SIZE

+larger than 0x10000(=64KB). Normally you want ADDR >= 0x1000000(=16MB), and

+SIZE also >= 16MB. A large SIZE could speed up the progression of dd.

+which will find a partition with uuid=7f95820f-5e33-4e6c-8f50-0760bf06d79c

+and set the partition as root if found.

+

+Example 2:

+

+	uuid ()

+

+which will print the uuid of the current root device.

+***                     gfxmenu support in grub4dos                        ***

+******************************************************************************

+

+Gfxmenu support has been added to grub4dos. To use it, you must first find the

+message file you need, then load it in menu.lst with command like this:

+

+	gfxmenu /message

+

+This should be a gloabl command, that is, not inside any menu item. Also, it

+can only be used in configure file, running it in console mode does not work.

+

+gfxmenu does not work in conjunction with the password feature.

+

+There are two major format of message file. Old format is created with gfxboot

+3.2.* or older (size of message file is normally about 150K), while new format

+is created with gfxboot 3.3.* and later (size of message file is normally above

+300K). Both format are supported in grub4dos.

+

+

+******************************************************************************

+***           Use 'write' to write a string into a device or file          ***

+******************************************************************************

+

+Usage:

+

+	write [--offset=SKIP] ADDR_OR_FILE INTEGER_OR_STRING

+

+SKIP is an integer and defaults to 0.

+

+If ADDR_OR_FILE is an integer, then it is treated as a memory address, and

+INTEGER_OR_STRING must be an integer value. The integer INTEGER_OR_STRING

+will be written to address (ADDR_OR_FILE + SKIP).

+

+If ADDR_OR_FILE is a device or a file, then INTEGER_OR_STRING is treated as

+a string which will be written to ADDR_OR_FILE at offset SKIP (in bytes).

+

+The string is quoted with nothing, that is, neither with the single quote

+char(') nor with the double quote char(").

+

+Space char must be quoted with back slash(\). (Update: need not now)

+

+Single quote char(') and double quote char(") are not interpreted specially

+and can be used directly in the string.

+

+Some C-style quote sequences are interpreted as follows:

+

+	\NNN	character with octal value NNN (1 to 3 digits)

+

+	\\	backslash

+

+	\a	alert (BEL)

+

+	\b	backspace

+

+	\f	form feed

+

+	\n	new line

+

+	\r	carriage return

+

+	\t	horizontal tab

+

+	\v	vertical tab

+

+	\xHH	byte with hexadecimal value HH (1 to 2 digits)

+

+Just like dd, the write can neither enlarge nor reduce the size of the

+destination file, the leftover tail of the string will be discarded.

+The destination file cannot be a gzipped file.

+

+Again like dd, the write command is also dangerous, use at your own risk.

+And to be on the safe side, you should only write to memory files.

+

+In some cases when writing a file in a NTFS volume, the write might fail.

+

+If you attempt to write a device or a block file that is not in memory by

+using write in a menu, you will safely be refused :-) (Update: no restrictions

+now)

+

+

+!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

+!!!!~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~!!!!

+!!!!    Caution! The file to write can be a device name which stands      !!!!

+!!!!    for all the sectors on the device. Take utmost care!              !!!!

+!!!!______________________________________________________________________!!!!

+******************************************************************************

+***                 Item-by-item help text for menu entries                ***

+******************************************************************************

+

+

+The help message at the bottom of the screen will vary as you choose the menu.

+

+You may append your help text to the title line. The help text must begin

+with "\n", for example:

+

+	title This is the title\nThis is the help text.\nAnd this is the 2nd line of the help text.

+

+Some C-style quote sequences are interpreted as stated in the section above.

+***        initrd can load multiple cpio files for Linux 2.6 kernels       ***

+******************************************************************************

+

+Usage:

+

+	initrd FILE [FILE ...]

+

+Note 1: You should not load more than one oldstyle disk images in this way,

+because this is not supported by Linux kernel.

+

+Note 2: The FILEs should be specified in the same order as with syslinux.

+***            access some internel variables at a fixed location          ***

+******************************************************************************

+

+Address		Length		Description

+=========	========	==============================================

+0000:8208	4 (DWORD)	install_partition (the boot partition)

+0000:8280	4 (DWORD)	boot_drive (the boot drive)

+0000:8284	4 (DWORD)	pxe_yip (your ip)

+0000:8288	4 (DWORD)	pxe_sip (server ip)

+0000:828C	4 (DWORD)	pxe_gip (gateway ip)

+0000:8290	8 (QWORD)	filesize (file size by last "cat --length=0")

+0000:8298	4 (DWORD)	saved_mem_upper (extended memory size in KB)

+0000:829C	4 (DWORD)	saved_partition (current root partition)

+0000:82A0	4 (DWORD)	saved_drive (current root drive)

+0000:82A4	4 (DWORD)	no_decompression (no auto gunzip)

+

+Note 1: Filesize can be initialised/modified by using "cat --length=0 FILE".

+Note 2: You should not write these variables by hand(should read only).

+Note 3: You may use 1K at 6000:0000 for your own varibles(See note 4).

+Note 4: The read command now returns the integer value at the given address.

+Note 5: Grub4dos does not have the variable expansion feature. You can only

+	use integer variables. You need not declare them, but use the memory

+	address directly. Usually you want to use variables as a logical

+	value or in a command for conditional test, e.g., of this form:

+		 "checkrange RANGE read ADDR"

+Note 6: no_decompression, saved_drive and saved_partition are writable.

+

+

+******************************************************************************

+***            possibility to run another menu.lst after gfxmenu           ***

+******************************************************************************

+

+Notice the use of CONFIGFILE after GFXMENU in the following example:

+

+	# The menu.lst file for gfxmenu

+	default=0

+	timeout=5

+	gfxmenu /message

+	configfile /another.lst

+	title 0..........

+	................

+	title 1..........

+	................

+	title 2..........

+	................

+	# End of menu.lst

+

+	# Begin another.lst

+	default=0

+	timeout=5

+	title 0..........

+	................

+	title 1..........

+	................

+	title 2..........

+	................

+	# End of another.lst

+

+This will try gfxmenu command first. On exit(or on failure) control will go

+to another.lst file.

+

+

+******************************************************************************

+***                   a range of drives can be unmapped                    ***

+******************************************************************************

+

+Usage:

+

+	map --unmap=RANGE

+

+RANGE is a range of BIOS drive numbers to be unmapped. BIOS drive number 0

+is for the first floppy, 1 is for the second floppy; 0x80 is for the first

+hard drive, 0x81 is for the second hard drive, etc; virtual cdrom (hd32)

+corresponds to BIOS drive number 0xA0, (hd33) corresponds to 0xA1, etc.

+

+For description on RANGE, please refer to section `The New Command CHECKRANGE'

+above.

+

+Example 1:

+

+	map --unmap=0,0x80,0xff

+

+This will unmap virtual floppy (fd0), virtual hard drive (hd0) and virtual

+cdrom (0xff).

+

+Example 2:

+

+	map --unmap=0:0xff

+

+This will unmap all virtual floppies, all virtual hard drives and all virtual

+cdroms.

+

+Note 1: Normally a `map' command will add an item in the drive map table for

+	a virtual drive. But `--unmap' means items in the drive map table

+	(for the specified virtual drives) will be deleted.

+Note 2:	The --unhook option only breaks the INT13 hook(to the inerrupt

+	vector table). It will not affect the drive map table. And later on

+	execution of a `boot' command, the INT13 disk emulation routine will

+	automatically get hooked(to the interrupt vector table) when needed

+	(e.g., the drive map table is non-empty) even if it has been unhooked.

+Note 3: Usually you want to do a `map --rehook' after you have changed the

+	drive map table.

+

+

+******************************************************************************

+***                         geometry tune and sync                         ***

+******************************************************************************

+

+When a USB storage device is connected to a (or another) machine, the geometry

+in the partition table or in the BPB of the volume could be invalid, and the

+machine could hang at boot time. So you need to find out the correct geometry

+for the drive (use `geometry --tune'), and then update the geometry in

+partition table and BPB of the drive(use `geometry --sync').

+

+The above steps are required if you are going to boot DOS, because DOS

+requires the right geometry in the partition table and BPB. Windows/Linux may

+also require it, since the boot process could run in real-mode.

+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+		    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+			    NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+	    How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) 19yy  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program; if not, write to the Free Software
+    Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
+
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) 19yy name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.

+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+Starting with 1.47, changes marked with SYSLINUX, PXELINUX, ISOLINUX
+or EXTLINUX apply to that specific program only; other changes apply
+to all derivatives.
+
+Changes in 4.02:
+	* SYSLINUX: correctly handle the case where the -d option is
+	  specified with a non-absolute path, i.e. "syslinux -d
+	  syslinux" instead of "syslinux -d /syslinux".
+	* ISOLINUX: recognize the directory names /boot/syslinux and
+	  /syslinux, and the filename syslinux.cfg in addition to the
+	  isolinux-specific names.  Thus, "syslinux.cfg" is now a
+	  generic name, whereas "isolinux.cfg" or "extlinux.conf" is
+	  specific to different derivative.
+	* chain.c32: support setting alternate config filename for
+	  stage2 of GRUB Legacy (Gert Hulselmans).
+	* whichsys.c32: execute specific command, based on Syslinux
+	  bootloader variant (Gert Hulselmans).
+	* lua.c32: a lot of new bindings added to the "syslinux"
+	  namespace: VESA, PCI, DMI, kernel loading (Marcel Ritter).
+	* btrfs: print a comprehensive error message if compressed or
+	  encrypted files are encountered (neither is currently
+	  supported.)
+	* SYSLINUX: mtools installer: honor TMPDIR, error out on disk
+	  full.
+	* Handle fallbacks from EDD to CHS, to deal with systems which
+	  announce EDD support but don't actually have it.
+	* SYSLINUX: the mtools, DOS and win32 installers now use the new
+	  command line options.
+	* PXELINUX: fix the use of IP addresses in TFTP :: or tftp://
+	  host syntax.
+	* SYSLINUX: experimental Win64 installer (syslinux64.exe).
+
+Changes in 4.01:
+	* ISOLINUX: fix initialization on systems which don't zero
+	  low memory.
+	* SYSLINUX/EXTLINUX: fix handing of disk read retries in
+	  EDD mode.
+	* ISOLINUX: change the initialization sequence to avoid
+	  problems with certain (old) BIOSes.  Special thanks to
+	  Helmut Hullen for invaluable debugging support.
+	* ifplop.c32: new module which detects if the PLoP Boot Loader
+	  already has booted a CDROM or USB drive (Gert Hulselmans).
+	* Correct a severe memory overwrite bug, triggered primarily
+	  when selecting a very long command line in the menu system.
+	* lua.c32: Lua script interpreter, currently experimental
+	  (Alexey Zaytsev, Marcel Ritter, Geert Stappers).
+	* PXELINUX: new option IPAPPEND 4 to append the system UUID to
+	  the kernel command line.
+	* PXELINUX: display BOOTIF and SYSUUID at startup time, and
+	  when Ctrl-N is pressed on the command line.
+
+Changes in 4.00:
+	* Major code base changes; all filesystem rewritten in C.
+	  This work was done primarily by Liu Aleaxander (Yuanhan Liu).
+	* EXTLINUX: btrfs and ext4 support.  btrfs support was done by
+	  Alek Du of Intel.
+	* EXTLINUX is no longer a separate derivative; extlinux and
+	  syslinux both install the same loader (ldlinux.sys); for the
+	  Linux-based installers the extlinux binary is used for a
+	  mounted filesystem; the syslinux binary for an unmounted
+	  filesystem.
+	* When loading a new configuration file with the CONFIG
+	  command, one can now also specify a new current directory
+	  with an APPEND statement.
+	* Full ADV support for Syslinux, to boot-once and MENU SAVE
+	  works.
+	* Full support of GPT-partitioned disks, including disks
+	  and/or parititions larger than 2 TiB (if supported by BIOS.)
+	* The GPT handover protocol adjusted to the current T13
+	  committee draft; see doc/gpt.txt.
+	* HDT: code cleanup, small bugfixes
+	* The "linux" syslinux installer (syslinux-nomtools) now has a
+	  command-line syntax closer to the extlinux installer.  The
+	  mtools, dos and win32 installers will get this new syntax
+	  eventually, but it is not implemented yet.
+	* chain.c32: support booting GPT partitions by index, GUID, label.
+	* chain.c32: support booting the Syslinux partition with "fs".
+	* chain.c32: implement gpt.txt hand-over protocol.
+	* chain.c32: support for chainloading Grub stage 2.
+	* PXELINUX: TFTP URL syntax (tftp://) supported even when not
+	  running gPXE/gpxelinux.
+	* New ls.c32 module to display the contents of the disk from
+	  the command line, and pwd.c32 to display the current
+	  directory.
+	* rosh.c32 (read only shell) updated and hopefully usable.
+	* PXELINUX: Support "localboot -1", just like the other
+	  derivatives.
+	* gfxboot.com removed in favor of gfxboot.c32.
+	* New MENU HELP statement to display fullscreen help text as a
+	  result of a menu selection.
+	* memdiskfind utility that can be used with the phram driver
+	  in the Linux kernel to mount a memdisk.
+        * ifcpu.c32: Adding usage when no parameters are given, 
+          adding PAE support.
+	* ifcpu.c32, ifcpu64.c32: handle more than one argument per
+	  target.
+	* isohybrid: C version which does not require Perl.
+	* New command MENU IMMEDIATE to permit hotkeys to activate
+	  immediately without needing Enter.
+	* mdiskchk.com supports a --no-sequential (or -n) option to
+	  suppress the classic all-drive-probing heuristic.  Useful
+	  on BIOSes who crash/hang when certain drive numbers are
+	  probed.
+	* ElTorito.Sys DOS driver now scans drive numbers upwards
+	  instead of downwards, in order to avoid a fairly common
+	  bug on some BIOSes where probing drive 0xFF causes a
+	  failure.
+	* NASM 2.03 or later required to build.  2.07 or later
+          recommended.
+
+Changes in 3.86:
+	* chain.c32: fix chainloading the MBR of a hard disk (broken
+	  in 3.85).
+	* mboot.c32: report the boot loader name in the information
+	  structure.
+	* com32: set argv[0] in a com32 module.
+	* core: add a workaround for a bug in Xen HVM older than
+	  version 3.3: disable halt on those platforms.
+	* Fix problems where certain operations in com32 modules would
+	  cause the core to believe the system was idle.
+	* MEMDISK: fix MBR detection when used with a DOSEMU header or
+	  an offset.
+	* MEMDISK: generate the mBFT checksum correctly.
+
+Changes in 3.85:
+	* gPXELINUX: updated to gPXE 1.0.0.  gPXELINUX can now do NBP
+	  chainloading, and does not require a second DHCP.
+	* vesamenu.c32: unbreak the default "grey hole" background.
+	* We no longer have a built-in default of "linux auto".
+	  Instead, if no DEFAULT or UI statement is found, or the
+	  configuration file is missing entirely, we drop to the boot:
+	  prompt with an error message (if NOESCAPE is set, we stop
+	  with a "boot failed" message; this is also the case for
+	  PXELINUX if the configuration file is not found.)
+	* chain.c32: support chainloading Grub4DOS; patch by Gert
+	  Hulselmans.
+	* New tool: sysdump.c32, can be used to produce system
+	  information for debugging via tftp or ymodem (serial port).
+	* "vga=current" on the Linux command line is now supported.
+	* chain.c32: support for Windows Recovery Console, via the
+	  "cmldr=" option.
+	* chain.c32: should now support loading NTLDR from different
+	  type media than loaded from.
+	* chain.c32: support chainloading to a FAT/NTFS partition with
+	  invalid "hidden sectors" via the "sethidden" option.
+	* memdisk: fix the mBFT ACPI table.
+	* vesamenu.c32: if the image is smaller than the screen, tile
+	  it across the whole screen.
+	* mkdiskimage: -s option for producing a sparse image.
+	* vesamenu.c32: support arbitrary resolution setting (beyond
+	  BIOS support) on some Intel-based video chipsets.  This code
+	  is a modified version of the "915resolution" tool by
+	  Steve Tomljenovic; your mileage might vary.
+	  
+Changes in 3.84:
+	* SYSLINUX: make the DOS installer work for MS-DOS 7.x/8.x
+	  (Win9x/ME) again.
+	* HDT: updated to version 0.3.6 (numerous changes.)
+	* mboot.c32: now supports video mode setting if requested by
+	  the image.
+	* MEMDISK: Fix floppy images of PC-DOS.
+	* MEMDISK: Add support for emulation of CD-ROM images; patch
+	  by Shao Miller.
+	* MEMDISK: Comply with the Win9x "safe hook" standard,
+	  allowing a protected-mode driver.
+	* MEMDISK: New "mBFT" ACPI table, by analogy with the iSCSI
+	  iBFT table.  This allows detection from a protected-mode
+	  operating system without EDD support.
+	* 32-bit version of the gfxboot loader (gfxboot.c32), so far
+	  experimental.  This will replace gfxboot.com in the future.
+	* vesamenu.c32: new MENU RESOLUTION directive to set a screen
+	  resolution other than 640x480.
+	* chain.c32: add support for loading isolinux.bin.
+	* chain.c32: make sure to always return to text mode.
+	* eltorito.sys: DOS driver for generic CD-ROMs; by Gary Tong
+	  and Bart Lagerweij.
+
+Changes in 3.83:
+	* PXELINUX: clear memory before handing over to a chainloaded
+	  NBP.  This may help avoid a bug in Windows RIS.
+	* PXELINUX: fix localboot after NBP chainloading on certain
+	  BIOSes (including ASUS A8N-E, but possibly others.)
+	* chain.c32: support chainloaded bootloaders on ISOLINUX.
+	* PXELINUX: allow filenames up to 251 characters.
+	* MEMDISK: fix problems booting from USB on Thinkpads, and
+	  possibly other machines or hardware combinations.
+	* isohybrid: fix the -id option.
+	* HDT: updated to version 0.3.4.
+	* MEMDISK: the stack size is now configurable, with the stack=
+	  option.
+	* Simple menu: fix Ctrl-W (word erase) in command-line edit.
+	* Simple menu: fix crash on some platforms.
+	* Gfxboot: fixes to the configuration file parsing.
+	* PXELINUX: add a tool to override specific DHCP options via
+	  values hardcoded in the pxelinux.0 file.  These hardcoded
+	  values can be either "before DHCP" (defaults if DHCP do not
+	  provide values), or "after DHCP" (overrides DHCP).  The tool
+	  pxelinux-options can be used to set these options.  This
+	  feature does not apply to gpxelinux.0; when used with gPXE
+	  this is better handled by modifying the embedded script.
+
+Changes in 3.82:
+	* isohybrid: fix the -partok logic for loading from a partition.
+	* ISOLINUX: deal with systems which return from INT 13h with
+	  interrupts disabled.
+	* Do not invoke the idle handler during large file loads.
+	* Simple menu: make ONTIMEOUT work with MENU HIDDEN.
+	* PXELINUX: handle TFTP servers which have extra NULs at the
+	  end of an OACK packet.
+
+Changes in 3.81:
+	* Shuffler: fix bug in real-mode entry.  This affected a
+	  number of modules, probably in relatively unimportant ways,
+	  but it completely broke linux.c32.
+	* Improved performance.
+	* Attempt to halt the processor while idle.  This can cause
+	  bad reponsiveness when using a serial console especially for
+	  automated input; if that ends up being a problem, use the
+	  new "NOHALT 1" configuration command.
+	* linux.c32 now suppresses all messages if the "quiet" flag is
+	  specified.
+	* isohybrid: add a variety of options, and a help message.
+	* ISOLINUX: fix booting in hybrid mode when CBIOS is used.
+	  This unfortunately means that the isohybrid handoff protocol
+	  has changed, so the isohybrid utility must version-match
+	  isolinux.bin.
+	* Drop support for ACPI 3 extended memory flags.
+	* Menu system: don't set the autocr flag on the serial
+	  console.
+	* altmbr: fix handling of logical partitions.
+	* altmbr: cap at 439 bytes so the partition select byte isn't
+	  part of the file.
+
+Changes in 3.80:
+	* New shuffler mechanism and API.
+	* Rewritten mboot.c32 module.
+	* The syslinux_boot_linux() function has been simplified.
+	* Don't hang trying to boot a "menu quit" label from the CLI.
+	* Fix problem with boot-once "sticking" on some BIOSes.
+	* isohybrid: fix problem with images over 2 GB in size.
+	* APM poweroff module (poweroff.com) by Sebastian Herbszt.
+	* ISOLINUX: fix the handling of large directories.  Bug found
+	  and fixed by Steffen Winterfeldt.
+
+Changes in 3.75:
+	* PXELINUX: fix the "keeppxe" option, which was broken in
+	  3.74.
+	* MEMDISK: correct the extraction of geometry information from
+	  the MBR of a hard disk image, again broken in 3.74.
+	* extlinux(1) man page from Brian Pellin.
+	* Simple menu: MENU SAVE is now controllable on a menu-by-menu
+	  or entry-by-entry basis.
+	* gPXELINUX: fix interrupt-disabling bug.
+	* HDT: fix lockup on machines with certain PCI configurations.
+
+Changes in 3.74:
+	* New UI directive, which allows a more natural way to specify
+	  a menu system (or not.)  With the UI directive specifying
+	  the menu system, the DEFAULT directive can be used to select
+	  the default entry inside the menus.
+	* kbdmap.c32: new module to load a new keyboard map
+	  dynamically.
+	* isohybrid: workaround bug in some versions of binutils.
+	* Fix issue with the placement of the initrd on some machines.
+	* ifcpu64: fix handling of less than three arguments.
+	* Fix bug in the shuffle library when dealing with a very
+	  large number of fragments.
+	* Documentation fixes by Vicente Jimenez Aguilar.
+	* gPXE updated to version 0.9.7.
+	* hdt.c32: Hardware Detection Tool, an interactive hardware
+	  analyzer module by Erwan Velu.
+	* MEMDISK: enable automatic determination of the disk geometry
+	  for a large floppy disk image if (and only if) it is
+	  formatted with a FAT filesystem.
+	* SYSLINUX: fix the handling of .bss files on FAT12/16.
+	* Suppress the Loading ... message if "quiet" is specified on
+	  the kernel command line.
+	* Fix the use of "CONSOLE 0" with menu.c32.
+	* Allow COM32 modules to be aware of all memory even in the
+	  presence of a memory hole.  The "linux.c32" module can be
+	  used to load a kernel (or memdisk) plus large initrd on
+	  such a system.
+	* MBR: produce alternate MBR variants which force the drive
+	  number to hd0 (_f variants), or force the drive number to
+	  hd0 if the Ctrl key is pressed (_c variants.)  Furthermore,
+	  add an MBR variant (altmbr*.bin) which ignores the active
+	  flag and instead boots the partition number specified in the
+	  byte at offset 439 decimal.
+	* Add IPAPPEND strings to com32 modules, especially needed for
+	  linux.c32.
+	* New MENU SAVE directive which saves the latest menu
+	  selection until the next boot.  Currently only implemented for
+	  EXTLINUX.
+	* gfxboot.com: *experimental* interface module to Steffen
+	  Winterfeldt's "gfxboot" graphical front end
+	  (http://gfxboot.sourceforge.net/).  Module by Sebastian Herbszt.
+
+Changes in 3.73:
+	* Upgrade gPXE to release version 0.9.5.
+	* Fix a number of build errors on various platforms.
+	* Handle systems with E820 "extended attributes" per ACPI 3.
+	  Someone "cleverly" decided to change the E820 spec in a
+	  backwards-incompatible manner!
+	* MEMDISK: default to "safeint".
+	* Adopt the moniker "The Syslinux Project", standard proper
+	  noun capitalization, to refer to the project as a whole.
+	  Thus, reserve the all-caps "SYSLINUX" to refer to the FAT
+	  loader.
+	* mboot.c32: add "-solaris" option to pass DHCP information to
+	  the Solaris kernel; required for automatic Solaris boot
+	  without using Solaris' pxeboot program.
+	* config.c32: trivial COM32 module to restart Syslinux with
+	  another configuration file from the command line (equivalent
+	  to the CONFIG command in the configuratin file.)
+
+Changes in 3.72:
+	* Include the pxechain.com module from Jeffery Hutzelman at
+	  Carnegie Mellon University.  This allows chaining another
+	  PXE boot program while changing the DHCP packet passed to
+	  it.
+	* Reorganize the Makefile system.
+	* Major PCI core cleanups and other source cleanup.
+	* gPXE code updated.
+	* Try to avoid memory-snooping attacks on passwords.  Note
+	  that if someone has root on the box, they generally don't
+	  need to compromise the boot loader...
+	* ISOLINUX: fix crash when given a zero-length file.
+	* sdi.c32: support gzipped SDI images.
+	* ISOLINUX: support generating images which can be either
+	  a CD-ROM or a hard disk (USB disk, etc.)  See
+	  doc/isolinux.txt for more information.
+	* Remote gdb support for COM32 modules; patch from Stefan
+	  Hajnoczi.
+	* Support beeps in F-key help in the simple menu system.
+	* Tab display of labels, based on a patch from Sebastian
+	  Herbszt.  Can be disabled with the NOCOMPLETE configuration
+	  command.
+	* "menu default" can now be specified after "menu begin", to
+	  indicate that a specific submenu should be the default entry.
+
+Changes in 3.71:
+	* Workaround for a VESA BIOS which tries to make DOS system
+	  calls(!!)
+	* Simple menu: fix navigation around disabled entries
+	  (or at least try to...)
+	* EXTLINUX: proper error message when confused about mount
+	  point.
+	* MEMDISK: be smarter about incompletely disabled floppies in
+	  the BIOS and about being the only floppy.
+	* Optionally allow initrd to be specified on a separate line
+	  rather than as part of the "append" line.  This is not
+	  recommended, but apparently makes life easier for some
+	  tools.
+	* SYSLINUX: if no config file is present, set the current
+	  directory to the root directory (Sebastian Herbszt).
+	* chain.c32: option "hide" to support hiding and unhiding of
+	  primary partitions on the boot drive with DOS, Win, or OS/2
+	  partition types (01, 04, 06, 07, 0b, 0c, 0e).
+	* Unbreak the KBDMAP command (broken in 3.70).
+	* EXTLINUX: fix the handling of the ADV when using CBIOS.
+	* ifcpu64.c32: simple COM32 module to select a 32- or 64-bit
+	  kernel (and optionally 32-bit kernels with or without PAE.)
+	  Eventually we want a scripting language for this
+	  kind of stuff; a Lua module is under development.
+	* Fix parsing of the SERIAL command without a baud rate
+	  specified.
+	* chain.c32: error out when try to boot an unbootable
+	  partition.
+	* SYSLINUX: when building the Win32 installer, search for
+	  MinGW under a large number of possible names.
+
+Changes in 3.70:
+	* PXELINUX: Support enhanced capabilities when running on top
+	  of gPXE (http://www.etherboot.org/).  In particular, support
+	  URL-style syntax for filenames, and any protocol that gPXE
+	  supports (except, currently, iSCSI and AoE.)  This feature
+	  is currently highly experimental.
+	* Substantial infrastructure changes to support files whose
+	  length aren't known at open time (typically network
+	  connections.)  Please note that the semantics of some of the
+	  comboot APIs have changed slightly; please see doc/comboot.txt.
+	* PXELINUX: We no longer require a TFTP server which supports
+	  the tsize option for all transfers.
+	* PXELINUX: Integrate with the gPXE source base; unified image
+	  now included as "gpxelinux.0".
+	* The source tree has been restructured; files that were
+	  previously in the root have moved into the core, dos, gpxe,
+	  and utils directories.
+	* "make install", "make netinstall", and "make extbootinstall"
+	  have been updated massively.  "make install-all" now installs
+	  all three.
+	* Change default dir for auxiliary files from
+	  /usr/lib/syslinux to /usr/share/syslinux.
+	* SYSLINUX: VFAT long filename support.
+	* MEMDISK: Any image less than 4096K (4 MB) is treated as a
+	  floppy disk.  The geometry-guessing code will recognize all
+	  common extended formats, but it is still possible some very
+	  exotic formats need geometry specification.  Large floppies
+	  and very small harddisks still need explicit specification.
+	* chain.c32: option "swap" to support swapping of BIOS drive
+	  numbers.  This is necessary to boot certain operating systems
+	  (DOS, Windows) from a secondary drive.
+	* chain.c32: option "file=" to support loading a boot file from
+	  the SYSLINUX filesystem instead of loading the boot sector
+	  from the drive.
+	* chain.c32: option "seg=" to control the load location.
+	* chain.c32: option "ntldr=" as a shorthand for "seg=0x2000
+	  file="; use this to load one of WinNT's loaders:
+
+	  chain.c32 hd0 1 ntldr=/MiniNT/setupldr.bin
+
+	  Note that the file needs to be in the SYSLINUX filesystem.
+	* chain.32: options "freedos=" and "msdos="/"pcdos=" as
+	  shorthands for "seg=0x60 file=" and "seg=0x70 file="
+	  respectively; use this to load FreeDOS's kernel.sys, MS-DOS's
+	  io.sys or PC-DOS's ibmbio.sys.
+	* Change to the A20 algorithm which *MIGHT* help systems that
+	  have systems which freeze when Syslinux is used with USB
+	  keyboards.  Note that this has been hard do verify, so I
+	  would greatly appreciate feedback on it.
+	* Complex menu system: unbreak menus which has unnamed
+	  submenus, like complex.c.
+	* Fix newline on the serial port for some com32 modules.
+	* chain.c32: support "boot" as the drive specification,
+	  indicating the drive from which it was booted
+	  (for syslinux/extlinux).
+	* SYSLINUX/EXTLINUX: support "localboot" with the same feature
+	  set as ISOLINUX.
+	* Add an experimental MBR for GPT partition tables.
+	* Use $(CC) when determining compile flags.
+	* chain.c32: fix booting from logical partitions (Sergey
+	  Vlasov.)
+
+Changes in 3.63:
+	* Fix errors in the PCI and DMI detection modules (Erwan Velu,
+	  Sebastian Herbszt).
+	* Fix host dependencies and other issues in the build system.
+	* PXELINUX: Allow class E addresses as unicast.
+	* sdi.c32: module to load Microsoft System Deployment Images.
+	  For additional information, please see:
+	    http://msdn2.microsoft.com/en-us/library/ms838543.aspx
+	* EXTLINUX: Correct reading directories with deleted entries.
+	* Shuffle library: correct the handling of certain geometries
+	  (an upward move with source material blocking the move); as
+	  required by sdi.c32 but theoretically possible for other
+	  formats as well.
+	* Add "make netinstall" to install /tftpboot.
+	* Fix some documentation files that didn't get moved/renamed.
+
+Changes in 3.62:
+	* Clean up garbage after "aborted." message.
+	* Clean up memdump.com filenames.
+	* Support SHA256 and SHA512 encrypted passwords.
+	* The shuffle library now can generate chained descriptors,
+	  thus allowing pretty much arbitrarily complex memory maps.
+	* Handle command lines up to 2047 characters, the current
+	  Linux kernel limit.
+	* vesamenu: support systems without linear framebuffer support
+	  (sigh, what is this, 1993?) and 15-bit RGB modes.
+	* Move the label storage (for the command-line interface) to
+	  high memory, removing the size limit and freeing up 64K of
+	  low memory.
+	* Get rid of 4096-entry limit in the simple menu system.
+	* New hierarchial submenu support: see MENU BEGIN, MENU END,
+	  MENU GOTO in doc/menu.txt.
+	* MENU QUIT allows creating a menu entry for returning to the
+	  command line.
+	* ISOLINUX: Work around bug in certain Adaptec BIOSes,
+	  patch by Bruce Robson.
+	* pngtopnm dependency removed from samples/ directory.
+	* Text documentation files (in doc/) renamed *.doc -> *.txt.
+
+Changes in 3.61:
+	* EXTLINUX: fix crash when accessing an empty file.
+	* elf.c32: If a PHDR segment is present, load it.
+	* Fix SHA-1 and MD5 passwords.
+	* ISOLINUX: fix booting when mastered without
+	  mkisofs -boot-info-table (broken since 3.50, sigh...)
+	* Handle BIOSes which emit multiple contiguous valid
+	  memory regions in the e820 map.
+
+Changes in 3.60:
+	* Support for "auxilliary data vector", a small amount of
+	  writable storage.  Currently only supported for EXTLINUX,
+	  but the infrastructure is there for the other derivatives,
+	  assuming a suitable storage location can be found.
+	* EXTLINUX: boot-once support (--once, --clear-once, and
+	  --reset-adv).
+	* A command is now required to the EXTLINUX installer, i.e. at
+	  least one of --install, --update, --once, --clear-once, or
+	  --reset-adv.
+
+Changes in 3.55:
+	* PXELINUX: as per RFC 5071, PXELINUX no longer requires the
+	  use of the magic cookie option (208) for unencapsulated
+	  options.  Currently it does not require it for
+	  vendor-encapsulated options (vendor-option-space) either,
+	  but that MAY be reverted in the future if it causes
+	  problems.
+	* Documentation text files moved to a common "doc" directory;
+	  man pages from the Debian project added to the "man"
+	  directory.
+	* Correct bug with self-overlapping memory areas when using
+	  the shuffle interface.
+
+Changes in 3.54:
+	* Add "menu separator", "menu indent", "menu disabled"
+	  (see README.menu).
+	* vesamenu: fix handing of VESA modes with noncontiguous
+	  memory buffers.  In particular, Qemu/KVM sets up such a mode
+	  when Cirrus Logic emulation is enabled (which is the
+	  default.)
+	* Support for calling real mode functions using far calls,
+	  with argument on the stack.  This was implemented to support
+	  the BIOS BBS specification, but subsequent experiments show
+	  that the at least one of the most common BIOS cores, Award,
+	  passes the presence check but doesn't actually implement the
+	  functionality.
+
+Changes in 3.53:
+	* Fix bugs related to the $PnP BIOS functionality on some
+	  platforms.
+	* PXELINUX: Fix the "naked" version of :: (suppress prefix.)
+	* elf.c32: better error messages.
+	* Faster operation under Intel VT virtualization.
+	* PXELINUX: Fix DHCP bootfile option.
+	* mkdiskimage: Support more than 1024 cylinders.
+	* (Hopefully) fix installer on non-x86 platforms.
+	* Fix shuffle_and_boot_rm, used by linux.c32.
+	* Fix shuffle_and_boot_pm on 386/486.
+	* ISOLINUX (at least): fix bss memory overwrite hang.
+	* MBR: Fix booting from logical partitions.
+	* Code cleanups.
+
+Changes in 3.52:
+	* Handle capitalized F-key commands in the menu system.
+	* Fix padding error when loading multiple ramdisks.
+	* Workaround for VMware crashing when trying to print a
+	  message during early kernel boot (does not seem to work,
+	  consider deleting.)
+	* chain.c32: add the ability to search for a specific MBR
+	  signature at runtime.
+	* Fall back to the server identity option if the siaddr field
+	  in the DHCP header isn't set.  This seems to match the
+	  behaviour of most PXE stacks.
+	* mkdiskimage: give the generated disk image an MBR signature.
+	* MEMDISK: Fix failures on some BIOSes.
+	* Simple menu system: new "MENU HIDDEN" option to not display
+	  the menu unless the user presses a key.
+	* Simple menu system: support MD5-encrypted passwords (modern
+	  Unix standard style, with "$1$" prefixes.)
+	* pcitest.c32: now functions as a full "lspci".  Thanks to
+	  Erwan Velu for this work.
+	* MEMDISK: Make EDD actually work.
+	* ISOLINUX: Fix for certain broken CD-ROM BIOSes which
+	  randomly corrupted register FS.
+	* Simple menu system: fix memory overwrite bug that caused
+	  some systems to lock up or behave weirdly.
+	* Fix building on 64-bit systems without a 32-bit libc installed.
+
+Changes in 3.51:
+	* EXTLINUX: Fix failure to find the configuration file.
+
+Changes in 3.50:
+	* New keywords allow the type of file to be specified in the
+	  configuration file.
+	* It is now supported to load a different configuration file
+	  with the CONFIG keyword.
+	* Fix API call 0x0019 (Read Disk.)
+	* MENU AUTOBOOT, MENU TABMSG, MENU PASSPROMPT allows
+	  internationalization of menu messages.
+	* A new feature, TEXT HELP, allows the administrator to set
+	  a multi-line help message for individual selections.
+	* Fix API call 0x0012 (Cleanup, shuffle and boot.)
+	* New API call "Cleanup, shuffle and boot to flat protected mode"
+	* New API call "Cleanup, shuffle and boot to real mode",
+	  similar to API call 0x0012 but allows arbitrary register setting.
+	* Introduce a library interface for loading arbitrary binary
+	  formats with relatively easily understood code.  See
+	  the elf.c32 module for an example on how to use it.
+	* New module "elf.c32", to load a protected-mode ELF kernel.
+	* MBR (old and new): Fix bug in CHS mode when LBA >
+	  65535*sectors.
+	* vesamenu: fix decoding of palettized PNG images.
+	* Update the Linux kernel boot protocol.
+	* PXELINUX: Press Ctrl-N at the boot prompt to read out the
+	  network info.
+	* Instead of the (non-existent) MAC, use the client identifier
+	  for networks like Infiniband and Firewire/1394.
+	* Add a new INCLUDE command to the core syslinux parser.
+	* Allow binding help text to F11 and F12.
+	* F-key help now available in the simple menu system.
+	* Disabled the polling for ARP during idle.  It is simply too
+	  slow on some (broken!) PXE stacks.
+	* PXELINUX: also try to fetch the config file based on UUID.
+	* SYSLINUX/EXTLINUX: New RAID mode (-r) which calls the BIOS
+	  to load the next device (typically the next drive) on boot
+	  failure.
+
+Changes in 3.36:
+	* MEMDISK: Disable EDD by default on floppy disks.  EDD can be
+	  enabled with the "edd" option and disabled with "noedd".
+	  This (hopefully) should make Ghost work again.
+	* SYSLINUX: "unix" installer now uses Linux ioctls instead of
+	  using libfat.
+	* New MBR which can boot from logical partitions.
+	* SYSLINUX: Fix bug in detecting special extensions which was
+	  introduced in 3.35 :(
+	* PXELINUX: Unbreak chainbooting FreeBSD (and possibly others.)
+
+Changes in 3.35:
+	* MEMDISK: New "safeint" mode.
+	* MEMDISK: Be more compliant with the PnP BIOS spec.
+	* MEMDISK: Turn on EDD support by default.
+	* MEMDISK: Try to work on some machines on which it would not
+	  work when there was no floppy drive in the system.
+	* Simple menu system: fix serial console support (broken in
+	  3.30).
+	* SYSLINUX: Support subdirectories.  Like ISOLINUX, the
+	  "current directory" is the directory in which syslinux.cfg
+	  is found; this is searched for in the sequence
+	  /boot/syslinux, /syslinux, /.  As a side benefit, label names
+	  like "linux-2.6.18" and "linux-2.6.19" are now supported.
+
+	  To install ldlinux.sys in a subdirectory, pass the -d
+	  directory option to the SYSLINUX installer.
+
+	  This work was sponsored by slax.org (thanks, Tomas!)
+	* New API call: read disk.
+	* Invoke ONERROR on initrd load failure.
+
+Changes in 3.31:
+	* The simple menu system (menu.c32 and vesamenu.c32) now
+	  support loading more than one configuration file at a time,
+	  using MENU INCLUDE or by specifying multiple filenames.
+	* The MENU COLOR statement can now control the shadowing mode.
+
+Changes in 3.30:
+	* libcom32 extended to support graphics mode and graphical console.
+	* vesamenu.c32, new graphical version of the Simple
+	  Menu System, see README.menu.
+	* New com32 modules by Erwan Velu do selection based on CPUID
+	  or PCI devices present.
+	* RPM spec: add syslinux-tftpboot module; move syslinux by
+	  default to the /usr/share/syslinux directory.
+	* RPM spec: extlinux is now a separate package.
+
+Changes in 3.20:
+	* EXTLINUX: New options --install (-i) and --update (-U), to
+	  make it clear if a boot loader should be installed or
+	  updated.  For now, defaults to --install for compatibility;
+	  a future version will require one of these options.
+	* New library functions to load and place files in memory.
+	* mboot.c32 bug fixes.
+	* Remove 8 MB kernel size restriction.
+	* Add "klibc" target for building unix/syslinux and
+	  extlinux/extlinux with klcc (klibc-1.4.27 or later.)
+	* PXELINUX: Fail (and eventually reboot) if no configuration
+	  file was found.
+	* COM32 module by Erwan Velu to make decisions based on DMI
+	  info.
+	* Fix issue where going back and forth between menus a lot
+	  would cause a hang.
+	* ISOLINUX: Fix bug which made "cd boot sectors" not work.
+
+Changes in 3.11:
+	* MEMDISK: Fix bug by which accessing the real floppy disk
+	  as B: in MS-DOS was broken.
+	* Simple menu system: allow tweaking of the screen layout.
+	* Simple menu system: better command-line editing, correctly
+	  handle command lines above 256 characters.
+	* PXELINUX: revert memory allocation change that caused
+	  problems on some network cards.
+	* MEMDISK: Try work around a bug on some BIOSes when no
+	  physical floppy disk is present in the system.
+	* Enable the 16550A FIFOs, if present, when doing serial
+	  console.
+	* New "totaltimeout" command establishes a timeout without
+	  regard for any user input.
+	* Simple menu system: timeout behaviour now more in line with
+	  user expectations.
+	* Simple menu system: "ontimeout" should now work correctly.
+
+Changes in 3.10:
+	* gcc 4.0.1 compilation fixes.
+	* Add support for querying the PCI BIOS in libcom32
+	  (used by ethersel et al.)
+	* Fix PCI handing (ethersel etc) on several old chipsets (and
+	  VMWare.)
+	* Try to deal with systems with broken EBIOS.
+	* New API call to do "localboot".
+	* New API call to query features.
+	* New API call to run kernel image, a lower-level call than
+	  "run command".  See comboot.doc.
+	* Fix for bug in EBIOS code discovered by Arwin Vosselman.
+	* NOESCAPE security fix.
+	* Comments are now recognized even without a space following #.
+	* Fix incorrect handling of mixes of entries with and without
+	  MENU PASSWD.
+	* The idle API call now harmlessly returns failure if it is a
+	  no-op.  That way the caller can decide whether or not to
+	  bother invoking it again.
+	* Temporarily disable the idle API call on PXELINUX, due to
+	  some platforms on which the idle API call seems to hang; this
+	  problem has not yet been debugged.
+	* MEMDISK: the handling of DOSEMU-headered images was broken;
+	  fix it.
+	* EXTLINUX: symlinks are now supported.
+	* Simple menu system: N and P now work correctly as hotkeys.
+	* MEMDISK: more BIOS bug workarounds.
+
+Changes in 3.09:
+	* gcc4 compilation fix.
+	* <BEL> (Ctrl-G) in message files now causes a beep.
+	* Reduce the command line to 511 characters; 1023 caused
+	  memory overflows.
+
+Changes in 3.08:
+	* SYSLINUX: Fix performance regression (-s mode always
+	  enabled.)
+	* Add API function for idle loop.
+	* libutil: Add do_idle() function for idle loop, make
+	  get_key() use it.
+	* libutil: Add SHA-1 and base64 functions.
+	* Simple menu system: add password support.
+	* EXTLINUX: Sparse files now handled correctly.
+	* EXTLINUX: Large directories now handled correctly.
+	* ALL: At the prompt, Ctrl-X now forces text mode.
+	* Fix configuration file parsing error, that could cause
+	  hangs.
+	* Rewritten advanced menuing system from Murali Ganapathy.
+	* MEMDISK: New "bigraw" mode to work around certain broken
+	  BIOS flash programs.
+	* COM32 module to boot Multiboot systems, including Xen.  See
+	  com32/modules/mboot.doc.
+	* Max command line changed to 1023 characters.  Note that the
+	  kernel proper still can only handle 255 characters without
+	  patching, and COM16 binaries can only handle 125 characters.
+
+Changes in 3.07:
+	* Fix chainloading (chain.c32).
+	* Fix zlib build problem.
+	* Use a private copy of <linux/ext2_fs.h>.
+
+Changes in 3.06:
+	* Fix typo that caused the ramdisk to load in the wrong place.
+
+Changes in 3.05:
+	* New API function "shuffle and boot"; allows COM32 modules to
+	  load or construct (almost) arbitrarily complex objects,
+	  e.g. a kernel and its initrd/initramfs in pieces, and have
+	  the API core reorganize memory for booting.  (A library API
+	  for this function will be introduced in a later version.)
+	* The initrd= option now supports multiple filenames separated
+	  by commas.  This is mostly useful for initramfs, which can
+	  be composed of multiple separate cpio or cpio.gz archives.
+	  (Note: all files except the last one are zero-padded to a 4K
+	  page boundary.  This should not affect initramfs.)
+	* EXTLINUX: Fix API function 000Ah (get derivative-specific
+	  info).
+	* libcom32/ethersel: Support PCI Config Mechanism #2 on
+	  machines still infested with that hideous old hack.
+	* SYSLINUX: Fix directory-parsing bug.
+
+Changes in 3.02:
+	* SYSLINUX: The "unix" installer now sets the MS-DOS
+	  attributes (hidden, system, readonly.)
+	* COM32 library: build the .lnx (test modules for running
+	  under Linux) as architecture native modules, in case
+	  i386 devel libraries aren't installed.
+	* EXTLINUX: Hack for systems which don't have BLKGETSIZE64
+	  defined in the standard header files.
+	* Simple menu system: minor aestetic improvements, and try to
+	  work better over a serial console (speed, and readability on
+	  monochrome terminal emulators.)
+	* New CONSOLE directive to control output on the video console
+	  (useful for dealing with some broken serial-forwarding
+	  BIOSes.)
+	* New com32 module "ethersel" for searching for an Ethernet
+	  card and selecting the proper version of Etherboot.
+	* EXTLINUX: Allow the user to override the detected geometry.
+	  Add help.
+
+Changes in 3.01:
+	* EXTLINUX, SYSLINUX: Fix compile errors on some systems.
+	* EXTLINUX: Default to zipdrive geometry (64 heads, 32
+	  sectors) if no other geometry can be detected.
+
+Changes in 3.00:
+	* SYSLINUX: Support FAT32 and EDD.  As an unfortunate
+	  consequence, LDLINUX.SYS is no longer an ordinary file; it
+	  is block-mapped at install time, which means it can only be
+	  written using the syslinux installers.
+	* SYSLINUX: Reorganize the source code for the installers;
+          each one of the installers (dos, win32, unix, mtools) is now
+          built in its own subdirectory.  In particular, "mtools" is
+	  the unprivileged installer which uses mtools; "unix" is the
+	  privileged installer which uses system calls.
+	* SYSLINUX: Completely rewritten DOS installer in C.
+	* ALL: "label" statement information is now stored in a
+	  compressed format, which means that a lot more labels are
+	  permitted (500-1000 in a typical configuration, but depends
+	  on the complexity.)
+	* EXTLINUX: New derivative, which boots from an ext2/ext3
+	  filesystem.
+	* SYSLINUX: The DOS and Win32 installers can now optionally
+	  write the boot sector to a file instead of the real boot
+	  sector.  This is not supported in the Linux installers,
+	  however.
+	* ALL: New NOESCAPE command, disables the "hold down the Shift
+	  key to display the prompt" behaviour.
+	* New simple menu system, as an alternative to the advanced
+	  menu system already present.  See README.menu for details.
+	* PXELINUX: Filenames can now be prefixed with an IP address
+	  or DNS name plus :: (e.g. 192.0.2.1::filename or
+	  server.domain.com::filename), which downloads a file from an
+	  alternate TFTP server, or just a :: (e.g. ::filename), which
+	  suppresses the common pathname prefix.  See pxelinux.doc.
+	* SYSLINUX: Add an -m option to the DOS and Win32 installers
+	  to write an MBR and -a to mark the partition SYSLINUX is
+	  being installed on active.
+	* MEMDISK: Give a way to query the boot loader type while
+	  running MEMDISK; see memdisk/memdisk.doc and
+	  sample/mdiskchk.c.
+	* mkdiskimage: substantially improved mkdiskimage which, among
+	  other things, can now be used to initialize USB keys as
+	  zipdrives; see README.usbkey for more information.
+
+Changes in 2.13:
+	* MEMDISK: Fix command-line parsing "brown paper bag" class
+	  bug.
+	* MEMDISK: Add "raw" mode to support the DOS boot disk from
+	  WinME/XP, which seems to deliberately crash the system
+	  when someone uses the "INT 15h mover" highmem API.
+	* Make "make install" do something sane for the com32
+	  development environment.
+	* In the spec file, create a separate -devel RPM for the com32
+	  development environment.
+
+Changes in 2.12:
+	* Simple C library, based on klibc, for writing COM32
+	  programs.
+	* Fix the handling of file length in loading of COM32
+	  programs.
+	* MEMDISK: Work around a linker bug by rearranging the code to
+	  not use the linker for the 16-bit code.
+	* SYSLINUX: If we're building on a machine without a Win32
+	  (mingw) compiler, just skip building syslinux.exe.
+	* ISOLINUX: Support non-mkisofs mastering programs, at least
+	  as long as the image is single-session.  For best results,
+	  ISOLINUX should be the only boot loader installed.
+	* MEMDISK: Allow the user to specify that the simulated disk
+	  should be write-protected.
+
+Changes in 2.11:
+	* ALL: Add an API call to get the configuration file name.
+	* SYSLINUX: Fix bug in 2.10 that prevented it from working
+	  correctly for a lot of people.
+	* SYSLINUX: In the installer, make mtools a bit less fussy.
+	* Make the menu system compile with newer gcc's.
+
+Changes in 2.10:
+	* MEMDISK: Handle images compressed with zip as well as with
+	  gzip.  Some Windows-based image tools apparently generate
+	  these kinds of images by default.  Patch by Patrick
+	  LoPresti.
+	* Major menu improvement from Murali Ganapathy.
+	* ISOLINUX: Wonderfully sick and brilliant workaround for
+	  severe bugs in certain Award BIOSes; from Knut Petersen.
+	* SYSLINUX: Fix for the nomtools installed, from Frederic
+	  Pasteleurs.
+	* PXELINUX: Fix handling of IP numbers in the ranges
+	  100-109 and 200-209.
+	* ALL: New option "allowoptions" (defaults to 1), which
+	  controls if options are allowed on the command line or not.
+	* SYSLINUX: Support building under klibc (see the klibc
+	  distribution for details.)
+
+Changes in 2.09:
+	* SYSLINUX: Remove residual setuid crap from
+	  syslinux-nomtools.
+	* Handle video pages correctly when using the API functions.
+	* Handle compiling on an x86-64 platform correctly.
+	* Menu system from Murali Krishnan Ganapathy; see the menu
+	  directory for information.
+	* COMBOOT: Allow COMBOOT programs to change screen text mode.
+	* COMBOOT: Correct the documentation of how to detect
+	  SYSLINUX from COMBOOT!!!!
+	* COMBOOT: Fix "get key without echo" API function.
+	* SYSLINUX: Fix bug that affected the API open function.
+	* ALL: Improve the E820 memory parser, to work around some
+	  buggy BIOSes.
+
+Changes in 2.08:
+	* Add new configuration command "ontimeout" to allow timeout
+	  to have a different action than just pressing Enter.
+	* Add new configuration command "onerror" to allow a custom
+	  command to be executed in case the kernel image is not found.
+	* Fix bugs in the COMBOOT/COM32 command-line parsing.  APPEND
+	  now works with COMBOOT/COM32 images.
+	* PXELINUX: Poll for ARP requests while sitting at the
+	  prompt.  This makes some boot servers a lot less unhappy.
+	* PXELINUX: Actually free sockets when we get a failure
+	  (including file not found.)  This bug would cause us to run
+	  out of sockets and thus "go deaf" after a while.
+	* MEMDISK: Add an API to query for the existence of MEMDISK.
+	* SYSLINUX: Fix loading boot sectors (.bs/.bss) from floppy
+	  disk.
+	* .c32 is now one of the extensions searched for
+	  automatically.
+	* PXELINUX: RFBG.exe seems to randomly overwrite memory
+	  location 0x5700.  Thus, don't use it!
+	* PXELINUX: Change pathname length max from 63 to 127; change
+	  max vkernels from 128 to 64.
+	* Support Ctrl-U -> kill entire command line input.
+	* The "samples" directory contains a (barely at all tested)
+	  chain loading example, chain.c32, which may be used to
+	  chainload local floppy disks and hard disks.  Use with
+	  "chain fdN" or "chain hdN [partition]"; N = 0 for the first
+	  drive of each type.
+
+Changes in 2.07:
+	* MEMDISK: Workaround for BIOSes which go into a snit when
+	  they get a RESET command for the floppy system when there is
+	  no floppy in the system.
+	* PXELINUX: Add "ipappend 2", which passes the hardware
+	  address of the boot interface to the kernel as a
+	  command-line option.
+	* mkdiskimage: fix the generation of the end limit.
+	* PXELINUX: Fix multiple bugs in chainloading of other NBPs.
+	* MEMDISK: Fix bug that would occationally cause "ran out of
+	  input data" when using compressed disk images.
+	* SYSLINUX: Updates for the win32 installer (from Lars Munch.)
+	* PXELINUX: PXELINUX-specific options are now recognized both
+	  in a vendor-option-space (a.k.a. type 43 encapsulated) as
+	  well as in a site-option-space (unencapsulated.)
+	* COM32: Don't crash when DS != 0.
+	* COMBOOT/COM32: Make file reading work correctly.  Thanks to
+	  Phung Chi Kien for submitting a test program.
+
+Changes in 2.06:
+	* ALL: Fix problem that would occationally cause a
+	  boot failure, depending on the length of the kernel.
+	* ISOLINUX: Fix problem that would occationally cause a
+	  boot failure, depending on the length of directories.
+	* SYSLINUX: Win32 installer now flushes buffers.
+	* ppmtolss16: Be fully compliant with the PNM spec;
+	  actually process comments in the header and odd
+	  alignments of the various parameters, as well as
+	  "plain" (not raw) files and PBM and PGM files.
+	* PXELINUX: Lower the default MTU to 1472 in order to deal
+	  with systems with slightly nonstandard MTUs, and PXE
+	  stacks which don't defragment correctly.  Unfortunately this
+	  is very hard to test dynamically.
+
+Changes in 2.05:
+	* PXELINUX: Add a default query based on the hardware address
+	  of the boot device.  This is in lower case hexadecimal form
+	  separated by dashes and including the hardware type, for
+	  example, the Ethernet (type 1) address 88:99:AA:BB:CC:DD
+	  would query the file pxelinux.cfg/01-88-99-aa-bb-cc-dd.
+        * PXELINUX: Fix bug involving non-IP-based config file names.
+	* SYSLINUX: New installer for WinNT-based systems, from Lars
+	  Munch.
+	* MEMDISK: Fix handling of memory region overlap when
+	  decompressing.  Thanks to Mikhail Kupchik for identifying
+	  the problem.
+
+Changes in 2.04:
+	* ALL: Reclaim even more low memory by observing that
+	  comboot_seg == real_mode_seg is perfectly fine, and by the
+	  fact that the 1000h segment managed to get unused in all
+	  derivatives...
+	* PXELINUX: Attempt to negotiate full Ethernet-sized blocks
+	  (1468 bytes) using the blksize option.
+	* SYSLINUX: Resurrect the old no-mtools version of the
+	  installer, although as a root-only tool.  Some distributors
+	  have indicated that they need a small standalone installer.
+	* MEMDISK: Fix a memory offset computation error when
+	  installing compressed disks which generally would cause
+	  1 MB of memory to be wasted.
+	* MEMDISK: Fix installing the E820 memory map.  Calling
+	  INT 15h AX=0E820h with MEMDISK 2.03 loaded would give a
+	  completely corrupt memory map.
+	* SYSLINUX: Make libsyslinux a dynamic library, so that it can
+	  be updated separately from client programs.  The whole idea,
+	  after all, is to enable alternate programs to become
+	  syslinux installers.
+	* Include an rpm spec file in the distribution, so rpmbuild
+	  -ta works.
+
+Changes in 2.03:
+	* Actually support comment lines in the configuration file.
+	* PXELINUX: Try to resolve some problems with stack switches.
+	* PXELINUX: Handle PXE stacks with broken routing.
+	  With these workarounds, the remote install PXE boot floppy
+	  (rbfg.exe) from Argon Technologies should work correctly.
+	* Fix problems with Perl scripts in UTF-8 locales.
+	* You probably need NASM 0.98.34 or later to compile this
+	  version.  0.98.36 is recommended.
+	* MEMDISK: Now supports gzip compressed images.
+
+Changes in 2.02:
+	* SYSLINUX: Security flaws have been found in the SYSLINUX
+	  installer when running setuid root.  Rewrite the SYSLINUX
+	  installer so it uses mtools instead.  It therefore now
+	  requires mtools (specifically mcopy and mattrib) to exist on
+	  your system, but it will not require root privileges and
+	  SHOULD NOT be setuid.
+
+Changes in 2.01:
+	* MEMDISK: Fix memory sizing bug when the ramdisk crosses the
+	  16 MB boundary.
+	* MEMDISK: Add a "pause" option to stop immediately before
+	  booting, to read off the messages.
+	* MEMDISK: Support disk images with DOSEMU headers.
+	* Update the mkdiskimage script to handle newer mtools
+	  versions, and be able to generate disk images with DOSEMU
+	  headers (controlled by the -d option).
+	* Fix the COM32 sample program.
+	* PXELINUX, ISOLINUX: Fix some COMBOOT API calls.
+	* PXELINUX: Doc fix.
+	* Build SYSLINUX into a small library for encapsulation into
+	  other programs (however, please keep in mind this is a GPL'd
+	  library.)
+	* SYSLINUX: Make installer work with "owner" in /etc/fstab.
+	* SYSLINUX: Fix issue with working on nonpartitioned hard disk
+	  devices.  THIS CONFIGURATION IS NOT RECOMMENDED.
+
+Changes in 2.00:
+	* ALL: Add support for "COM32" (32-bit COMBOOT) images.
+	* ALL: Add an API for COMBOOT/COM32 images.  See comboot.doc
+	  for details.  There is a C development environment for
+	  COM32 being created; it should be ready at some point in
+	  the future.
+	* Fix mbr.asm so that it actually works.
+	* SYSLINUX: The syslinux installer *SHOULD* now be safe to
+	  run setuid root.
+	* PXELINUX: Fix bug where PXELINUX would override random
+	  chunks of the UNDI code segment!  Thanks to Kevin Tran for
+	  finding this bug.
+	* ISOLINUX: Fix a bug related to slashes in pathnames.
+	* ISOLINUX: Fix a bug in handling initrds over 128 MB.
+	* ALL: Make the <Ctrl-V> key print out the version; this is
+	  to help debugging.
+	* Add a small script, mkdiskimage, to create a DOS-formatted
+	  hard disk image using mtools.  This may be useful in
+	  conjunction with MEMDISK.
+	* ISOLINUX: Search for a /boot/isolinux directory as well as
+	  /isolinux.
+	* ALL: Fix a bug related to very long configuration files.
+	* PXELINUX: Work around a NASM bug which would result in no
+	  delay before reset if an error occurs.
+
+Changes in 1.76:
+	* ISOLINUX: Remove code no longer used which caused hangs on
+	  some Toshiba laptops.
+
+Changes in 1.75:
+	* ALL: NASM 0.98.32 or later is now required to build
+	  SYSLINUX from sources.
+	* SYSLINUX: put back in the workaround for the BIOS floppy
+	  table.  This seems to be a requirement for "extended" floppy
+	  formats to work correctly.
+	* SYSLINUX: No longer warn if one is trying to boot on a 286
+	  or older.  The above BIOS workaround no longer fits if the
+	  requirement to use only 8086-compatible code in the early
+	  boot is maintained.  It made sense in 1994, but in 2002 a
+	  286 or older is a museum object.
+	* SYSLINUX: Use a downright bizarre, stateful algorithm to try
+	  to guess the maximum transfer size.  I am *hoping* this will
+	  cut down on the number of systems for which -s is required
+	  to work at any acceptable speed.
+	* ISOLINUX: Add a few more workarounds for various broken El
+	  Torito BIOSes.
+	* Make sure .depend files aren't accidentally packed...
+	* ALL: Fix bugs in the extension-detect code; this caused
+	  files like COMBOOT images and CD boot sectors to be
+	  mis-identified as Linux kernels and rejected.
+	* ALL: Fix the return from COMBOOT.
+	* ALL: Do some of the early groundwork for supporting DOS
+	  system calls in COMBOOT.
+	* Get rid of unnecessary "near" directives, making the code
+	  bigger.
+	* PXELINUX: Put the PXE stack back in the init state before
+	  invoking a chain-loaded NBP.
+	* PXELINUX: Actually found the combination of calls that
+	  allows some (most?) PXE 2+ stacks to be unloaded from memory
+	  properly.
+	* PXELINUX: Add "keeppxe" command-line option to disable
+	  the standard unloading of the PXE stack.
+
+Changes in 1.74:
+	* SYSLINUX: fix bug that would cause valid kernel images to be
+	  labelled "invalid".
+
+Changes in 1.73:
+	* Work on removing gratuitous differences between modules.
+	* Break up the source in common and module-specific files.
+	* PXELINUX: Allow chaining of other PXE NBPs.
+	* ISOLINUX: Allow loading "CD-ROM boot sectors".
+	* ALL: generalize the definition of a boot sector/NBP.
+
+Changes in 1.72:
+	* PXELINUX, ISOLINUX: Fix bugs in the new core code.
+
+Changes in 1.71:
+	* Fix a "brown paper bag" class bug in the new core code.
+
+Changes in 1.70:
+	* Major code restructuring.
+	* Relax the conventional memory limits somewhat.
+	* MEMDISK: Set up the "version number string" pointer in the
+	  header correctly.
+        * SYSLINUX: Fix, again, "the bug that won't die": the use of
+          the offset parameter with the SYSLINUX installer.
+	* SYSLINUX: Fix possible superblock corruption problem in the
+	  SYSLINUX installer.
+
+Changes in 1.67:
+	* Handle bug in the location of initrd.
+
+Changes in 1.66:
+	* MEMDISK: Make compile with newer versions of gcc.
+
+Changes in 1.65:
+	* ISOLINUX: Support booting disk image files (to boot DOS or
+	  other non-Linux operating systems), *IF* the BIOS works
+	  correctly; unfortunately many BIOSes apparently don't.
+	* Support Linux boot protocol version 2.03 (explicitly
+	  specify the initrd address limit.)
+	* Handle small "pseudo-kernels"; images that use the Linux
+	  kernel boot protocols but are less than 64K in size.
+	* MEMDISK: New subsystem; this is a driver which allows
+	  legacy OSes to boot using an in-memory simulated disk.
+	  See memdisk/memdisk.doc for more info.
+	* PXELINUX, ISOLINUX: Correctly handle files larger than 65535
+	  blocks (32 MB for PXELINUX, 128 MB for ISOLINUX.)
+	* PXELINUX: Make a best-effort attempt at freeing all memory
+	  claimed.  From the looks of it, it will fail on most PXE
+	  stacks.
+
+Changes in 1.64:
+	* Limited support for hardware flow control when using a
+	  serial port console.
+	* Support specifying the serial port I/O address explicitly.
+	* Make DOS installer hopefully behave more nicely when used on
+	  recent Windows versions.
+	* Fix returning to text mode when a font has been specified.
+	* Attempt to detect missing serial port hardware and disable
+	  the serial port if there is nothing there.
+
+Changes in 1.63:
+	* Make the ppmtolss16 program handle color conversion more
+	  correctly.
+	* Clean up "make install" target, honour INSTALLROOT if it
+	  exists.
+	* SYSLINUX: Fix stack-smash bug identified by Steffen
+	  Winterfeldt.
+	* Hopefully fix return-to-text-mode on some graphics cards.
+	* ISOLINUX: Bug workaround for Award BIOS 4.51, and perhaps
+	  other buggy BIOSes as well.
+
+Changes in 1.62:
+	* PXELINUX: Allow the DHCP server to override the
+	  configuration file name and pathname prefix, using
+	  "site-specific" DHCP options.
+	* PXELINUX: Documentation fixes.
+	* PXELINUX: Fix the "ipappend" option; the last two values
+	  were reversed vs. what the kernel expected.
+	* Introduce a way to return to text mode once we are already
+	  in graphics mode.  This may be useful for F-key help
+	  screens.
+	* Fix several bugs in the way return to text mode was handled.
+
+Changes in 1.61:
+	* ISOLINUX: Support full pathname searches.  Max length for a
+	  pathname is 255 characters.  As a result, only 64 "label"
+	  statements are supported in ISOLINUX.
+	* PXELINUX: Max filename length extended to 63 characters.
+
+Changes in 1.60:
+	* Add support for graphical splash screens.
+	* Add mode control characters, which allows you to control
+	  message display output depending on output mode (text,
+	  graphics, or serial port.)
+	* ISOLINUX: New program, which boots Linux from a CD-ROM
+	  without using floppy emulation mode.  See isolinux.doc for
+	  more details.
+	* PXELINUX: Don't search for boot sector file types, since
+	  they don't work anyway.
+	* SYSLINUX: Document the LOCK command for Win9x, and the error
+	  dialog box for WinNT/2K.
+
+Changes in 1.54:
+	* PXELINUX: Fix code for finding !PXE from PXENV+.  This was
+	  due to a spec bug; match the most recent spec since that
+	  seems to be what implementations actually do.
+	* SYSLINUX: Add some smarts to the boot sector, which
+	  hopefully should reduce the number of systems which require
+	  stupid mode ("syslinux -s").
+	* PXELINUX: Document further some of the pathologies with old
+	  PXE stacks.
+	* When specifying a "default" command line, no longer
+	  automatically appent "auto".  See the "DEFAULT" command in
+	  syslinux.doc for more information.
+	* PXELINUX: Clean up the allocation of local socket numbers.
+
+Changes in 1.53:
+	* PXELINUX: Rename pxelinux.bin to pxelinux.0, to match what
+	  most PXE servers seem to expect.
+	* PXELINUX: Update the DHCP/boot server setup documentation.
+	* PXELINUX: Support new "localboot" option for "label"
+	  sections.
+	* PXELINUX: More robust parsing of DHCP/boot server packets.
+	* PXELINUX: Include a small utility program "gethostip" to
+	  compute hexadecimal IP addresses.
+
+Changes in 1.52:
+	* PXELINUX: Fix bugs introduced by new A20 code.  (SYSLINUX
+	  has also been changed for code consistency reasons, but I'm
+	  pretty sure the changes are don't care on SYSLINUX.)
+	* Documentation updates.
+	* PXELINUX: Add "ipappend" option to generate an ip= option to
+	  the kernel.
+
+Changes in 1.51:
+	* PXELINUX: Not all PXE stacks fill in the IP address for a
+	  type 3 cached info query.  Use a type 2 cached info query
+	  for this information (only.)
+	* Yet another attempt at A20 coding.  Now support BIOS call
+	  15:2401 as well, and handle machines which always have A20
+	  on separately.
+	* Support memory detection using INT 15h, AX=0E820h.  BIOS
+	  manufacturers have apparently gotten sloppy about keeping
+	  INT 15h, AX=0E801h working properly.
+	* Don't issue <CR><LF> onto the serial port when we're doing
+	  screen wraparound.
+
+Changes in 1.50:
+	* Yet another A20-code update.  It seems some "legacy-free"
+	  machines and embedded gear simply don't have a KBC to talk
+	  to, and that waiting for one will wait forever.  Sigh.
+
+Changes in 1.49:
+	* SYSLINUX: Implement a hack for BIOS drivers which hog significant
+	  chunks of low memory during boot.  (Note: PXELINUX already
+	  had this modification.  SYSLINUX does still require that the
+	  low 512K is available; PXELINUX requires 384K.  Machines
+	  with a physical memory hole in the low 640K cannot boot
+	  Linux no matter what.)  Depending what the reason is for the
+	  memory hole, a new kernel (2.4.0-test3-pre3 or later) may be
+	  required.
+	* SYSLINUX: Default installer binary now compiled against
+	  glibc 2.1.  If this is inappropriate for your system and you
+	  still want to use the offical version of SYSLINUX, please
+	  follow the instructions in "distrib.doc" to rebuild the
+	  installer.
+	* SYSLINUX: Linux installer program now supports -o <offset>
+	  option which does a loopback mount with the
+	  -o loop,offset=<> option.  Useful to run SYSLINUX on an
+	  individual partition of a whole-harddisk image.
+	* Include the source code to a Master Boot Record (MBR)
+	  functionally equivalent to the one installed DOS except it
+	  includes EBIOS support, and should be resistant to geometry
+	  changes.  The MBR code is public domain.
+	* PXELINUX: Fix "double p" bug: if the tftp prefix was null,
+	  all filenames would get a "p" preprended, e.g.
+	  "ppxelinux.cfg" and "pvmlinux".
+
+Changes in 1.48:
+	* PXELINUX: Workaround for PXE ROMs based on the Intel PXE PDK
+	  3.0 build 071 and earlier: missing !PXE structure pointer.
+	* PXELINUX: Handle larger BOOTP/DHCP packages.
+	* PXELINUX: The command line passing was broken; fix.
+	* PXELINUX: Make COMBOOT images work.
+	* PXELINUX: Documentation on how to make booting work using
+	  the PDK 3.0-derived clients, which aren't so generous as to
+	  allow booting with only "PXEClient" specified.
+
+Changes in 1.47:
+	* PXELINUX: RFC 1123 states that a TFTP implementation MUST
+	  use adaptive timeout, "at least an exponential backoff of
+          retransmission timeout is necessary."  Implement a very
+	  simple exponential backoff for retransmits.
+	* PXELINUX: Updated documentation, including pointer to new
+	  TFTP server.
+	* PXELINUX: When sending ERROR due to bad OACK, use the proper
+	  destination port number (why are TFTP port numbers so odd?)
+	* PXELINUX: If the boot dies in the middle somewhere,
+	  eventually give up and reset the machine (unattended
+	  operation.)
+
+Changes in 1.46:
+	* New program PXELINUX to do network booting using a
+	  PXE-compliant (Pre-Execution Environment) network booting
+	  PROM.  See pxelinux.doc for details.
+
+Changes in 1.45:
+	* Serial console support.  See syslinux.doc for details.
+
+Changes in 1.44:
+	* Change HIGHMEM_MAX to 38000000h to (hopefully) avoid the
+	  kernel stepping on it; 3f000000h was apparently a higher
+	  limit than the kernel used!
+
+Changes in 1.43:
+	* Add sys2ansi.pl script to display the contents of a
+	  colorized SYSLINUX file.
+	* Changed the io_delay once again, after a report that the
+	  old delay port causes hangs on some systems.
+
+Changes in 1.42:
+	* Frob the "fast A20 gate" port as well as the keyboard
+	  controller; will this help systems with problems?
+	* Be even more paranoid about A20, unfortunately even this
+	  seems to be not paranoid enough... what I don't understand
+	  is that if there is hardware out there *this broken*, how
+	  can it run Linux at all?  Report an error message rather
+	  than hang forever if A20 is stuck.
+	* Include some intermediate files in the distribution, plus
+	  provide a "make installer" target for distributors to relink
+	  the install programs only.  I would prefer the syslinux boot
+	  loader proper to be "binary clean" for debuggablity -- use
+	  "make clean ; make installer" to rebuild the installers only.
+
+Changes in 1.41:
+	* Don't get confused by directories, volume labels, or VFAT
+	  long names.
+	* Use INT 15h, AX=0E801h to query memory size before trying
+	  INT 15h, AH=88h.  This not only provides more headroom
+	  between the kernel and the initrd on large-memory machines,
+	  but it appears some recent BIOSes actually have started
+	  returning garbage for the AH=88h (older) call.
+	* Trust high memory beyond the 15 MB mark if the user has
+	  specified it, or if obtained with INT 15h, AH=0E801h (with
+	  no memory holes above 1 MB.)
+
+Changes in 1.40:
+	* Increase A20M delay and put in a test to avoid problems on
+	  certain IBM Thinkpads (thanks to Donnie Barnes of RedHat
+	  for vital info on this one.)
+	* Support COMBOOT style boot command images.
+	* Support chain loading (foreign operating systems, e.g. DOS).
+	* Include a new "copybs" DOS utility to copy a boot sector to
+	  a file (under Linux, use "dd".)
+	* Fix the DOS installer to work for disks over 32 MB.
+	* SYSLINUX should now handle disks with more than 65536 tracks.
+
+Changes in 1.37:
+	* Fix a bug that caused "label" statements in syslinux.cfg to
+	  not be handled properly.
+	* Updated the documentation.  Among other things, we now allow
+	  up to 128 "label" statements.
+
+Changes in 1.36:
+	* Fix for booting old (pre-initrd) kernels.
+	* It seems at least some versions of OS/2 doesn't set up all
+	  the fields in the superblock correctly.  Account for that.
+	* Fix bug that caused boot failure when using the mem= option.
+
+Changes in 1.35:
+	* Loading from partitions now should work properly.  (Actually
+	  tested, this time.  You should even be able to dd a floppy
+	  to a partition and boot from it.)
+	* Removed large workaround code for an alleged ancient BIOS
+	  bug I have never actually seen.  The -s option should work
+	  on those machines, anyway.
+	* Support for simple keyboard remappings, same as used by
+	  LILO (once again to support localization.)  The program
+	  keytab-lilo.pl from the LILO distribution included to
+	  generate such maps.
+	* Added a "safe, slow and stupid" (-s) option to the
+	  installers.  This option will lobotomize the boot sector to
+	  hopefully work on even very buggy BIOSes.
+
+Changes in 1.34:
+	* Ability to load a VGA font on bootup (for localized Linux
+	  distributions.)
+
+Changes in 1.33:
+	* Bug fix in the Linux installer.
+	* Added a workaround for a bug in certain AMI/Intel BIOSes
+	  when booting from CD-ROM.
+	* Documentation changes.
+
+Changes in 1.32:
+	* FAT16 filesystems are now supported.
+
+Changes in 1.31:
+	* Now compiles under Linux, using NASM, rather than using
+	  Turbo Assembler under DOS.  See http://www.cryogen.com/Nasm
+	  for information about NASM.
+	* Linux-hosted SYSLINUX installer, as well as a
+	  rewritten DOS installer (now is written in assembler, so we
+	  don't need Turbo C.)
+
+Changes in 1.30:
+	* Added support for loading bzImage and initrd loading, and made
+	  SYSLINUX new-setup-code aware (SYSLINUX 1.30 id=0x31).
+	* Added LILO-style kernel labels; see the LABEL and IMPLICIT
+	  keywords in README file.
+	* Added support for colorization of intro and help screens.
+	* The vga= option is now handled correctly.
+	* Massive rewrite of large chunks of the code in order to
+	  support the first two new features.
+
+Changes in 1.20:
+	* Added simple online help at the "boot:" prompt.
+	* Removed 2880K image as I no longer have access to such a
+	  floppy drive.	 (Donations accepted!!)
+	* Decided to distribute the source in a subdirectory rather
+	  than in a nested zipfile.
+
+Changes in 1.11:
+	* Removed a sanity check which would cause booting to fail on
+	  Phoenix BIOS version 4.03.  Apparently this BIOS is buggy.
+
+Changes in 1.10:
+	* Added configuration file SYSLINUX.CFG.  This file contains all
+	  configurable options, and can be edited from any OS which can
+	  access an MS-DOS filesystem; there is no longer a need to run
+	  SYSLINUX.EXE except to write the boot sector.
+	* Default command line now given by "default" line in config
+	  file.
+	* LINUXMSG.TXT and BOOTMSG.TXT hard-coded file names replaced by
+	  "display" and "prompt" lines in config file.
+	* LILO-style option appending now supported ("append" line in
+	  config file).
+	* Prompt timeout is now supported ("timeout" line in config
+	  file).  The timeout is cancelled when anything is typed on the
+	  command line.
+	* Pressing <ESC> or <Ctrl-C> at the Loading... stage now aborts
+	  the kernel loading in progress and returns the user to the
+	  boot: prompt.
+	* The installer now automatically sets the READONLY flag on
+	  LDLINUX.SYS.
+	* Added 2880K disk image.
+
+Changes in 1.03:
+	* Fixed bug that would prevent booting from double-density
+	  floppies and other DOS filesystems with multiple sectors per
+	  cluster.
+	* Added 720K disk image.
+	* Changed default kernel name on disk images to LINUX.
+
+Changes in 1.02:
+	* Fixed bug that would garble the command line on recent kernels
+	  with more than 4 sectors of setup code (this wasn't really a
+	  *bug*; rather, a kernel change broke the code.  Unfortunately
+	  the Linux boot interface is still sorely undocumented).
+	* Added BOOTMSG.TXT file support (message file which does not
+	  force display of the boot prompt).
+
+Changes in 1.01:
+	* Fixed bug on some (most?) 386 BIOSes would require two boot
+	  attempts.

+#
+#	General notes:
+#
+#	This table contains the data the Unicode Consortium has on how
+#       ISO 8859-7:2003 characters map into Unicode.
+#
+#	ISO 8859-7:1987 is equivalent to ISO-IR-126, ELOT 928,
+#	and ECMA 118. ISO 8859-7:2003 adds two currency signs 
+#	and one other character not in the earlier standard.
+#
+#	Format:  Three tab-separated columns
+#		 Column #1 is the ISO 8859-7 code (in hex as 0xXX)
+#		 Column #2 is the Unicode (in hex as 0xXXXX)
+#		 Column #3 the Unicode name (follows a comment sign, '#')
+#
+#	The entries are in ISO 8859-7 order.
+#
+#	Version history
+#	1.0 version updates 0.1 version by adding mappings for all
+#	control characters.
+#	Remap 0xA1 to U+2018 (instead of 0x02BD) to match text of 8859-7
+#	Remap 0xA2 to U+2019 (instead of 0x02BC) to match text of 8859-7
+#
+#	2.0 version updates 1.0 version by adding mappings for the
+#	three newly added characters 0xA4, 0xA5, 0xAA.
+#
+#	Updated versions of this file may be found in:

+Changes in v1.2
+---------------
+* Allowed menu's to have names. Submenu's can be referred to by names
+  instead of their index in the menu system. This allows user to refer
+  to submenus which are not yet part of the menusystem.
+* help pages can be longer than one screen
+* menugen.py: Python script for converting .menu files to C source code
+  .menu files can be used to descibe most static uses of menu system,
+  including SubMenus, Checkboxes, RadioButtons, User Authentication and
+  Context sensitive help. You can also restrict use of certain items
+  to users with certain credentials.
+
+  See MENU_FORMAT for the format of .menu files
+
+* display.c32: Takes the name of the text file to display and displays it
+  allowing user to scroll through the text.
+
+  USAGE: display.c32 <filename>
+
+  <filename> must be an absolute filename (including the /isolinux part)
+
+Changes in v1.1
+---------------
+* Additional handler type: Keys handler
+* Menuitem handlers now have a return value of type t_handler_return.
+  For all simple cases, you just return ACTION_VALID or ACTION_INVALID
+  (For some types of menu items, handlers are ignored, and for
+   others the return value is ignored)
+* add_menu takes an extra argument (to better control memory footprint)
+  You can just set it to -1 to choose the default value
+* Now the menu system support long menu's using scroll bars.
+* Support for passwords and context sensitive help is added.

+GCC & 32-bit code
+-----------------
+Due to the limitations of the COM file format,
+(64KB limit on memory footprint) the code has been changed
+so that the code compiles to a 32-bit COMBOOT program.
+Since the code makes use of BIOS calls, this code cannot be
+compiled into a format which can execute under Linux. As a
+side effect, there is no nice way to debug this code. In order
+to debug this code, you will have to run the code under syslinux.
+
+GCC & 16-bit code
+-----------------
+The code was ported to GCC by Peter Anvin.
+
+OpenWatcom & 16-bit code
+------------------------
+Originally this code was written for the Openwatcom compiler
+and generated .COM files, which could execute under DOS as well as
+SYSLINUX.

+          Overview of writing code using the menu system
+          ----------------------------------------------
+
+This file contains implementation and developer documentation.
+For simple cases, you should start by using simple.c as a template.
+complex.c illustrates most of the features available in the menu system.
+
+Menu Features currently supported are:
+* menu items,
+* submenus,
+* disabled items,
+* checkboxes,
+* invisible items (useful for dynamic menus), and
+* Radio menus,
+* Context sensitive help
+* Authenticated users
+
+The keys used are:
+
+* Arrow Keys, PgUp, PgDn, Home, End Keys
+* Space to switch state of a checkbox
+* Enter to choose the item
+* Escape to exit from it
+* Shortcut keys
+
+1. Overview
+-----------
+
+The code usually consists of many stages.
+
+ * Configuring the menusytem
+ * Installing global handlers [optional]
+ * Populating the menusystem
+ * Executing the menusystem
+ * Processing the result
+
+1.1 Configuring the menusystem
+------------------------------
+This includes setting the window the menu system should use,
+the choice of colors, the title of the menu etc. In most functions
+calls, a value of -1 indicates that the default value be used.
+For details about what the arguments are look at function
+declarations in menu.h
+
+<code>
+  // Choose the default title and setup default values for all attributes....
+  init_menusystem(NULL);
+  set_window_size(1,1,23,78); // Leave one row/col border all around
+
+  // Choose the default values for all attributes and char's
+  // -1 means choose defaults (Actually the next 4 lines are not needed)
+  set_normal_attr (-1,-1,-1,-1);
+  set_status_info (-1,-1);
+  set_title_info  (-1,-1);
+  set_misc_info(-1,-1,-1,-1);
+</code>
+
+1.2 Populating the menusystem
+-----------------------------
+This involves adding a menu to the system, and the options which
+should appear in the menu. An example is given below.
+
+<code>
+  MAINMENU = add_menu(" Menu Title ",-1);
+  CHECKED = 1;
+  add_item("option1","Status 1",OPT_RUN,"kernel1 arg1=val1",0);
+  add_item("selfloop","Status 2",OPT_SUBMENU,NULL,MAINMENU);
+  add_item("othermenu","Status 3",OPT_SUBMENU,"menuname",0);
+  add_sep();
+  add_item("checkbox,"Checkbox Info",OPT_CHECKBOX,NULL,CHECKED);
+  add_item("Exit ","Status String",OPT_EXITMENU,NULL,0);
+</code>
+
+The call to add_menu has two arguments, the first being the title of
+the menu and the second an upper bound on the number of items in the menu.
+Putting a -1, will use the default (see MENUSIZE in menu.h). If you try
+to add more items than specified, the extra items will not appear in
+the menu. The accuracy of this number affects the memory required
+to run the system.
+
+If you do not want to keep track of the return values, you can also use
+the following variant of add_menu
+
+<code>
+add_named_menu("main"," Menu Title ",-1)
+</code>
+
+This creates a new menu as before and gives it a name "main". When using named
+menus, you get an alternate way for adding submenu's. See below for details.
+
+The call to add_item has five arguments.
+The first argument is the text which appears in the menu itself.
+The second argument is the text displayed in the status line.
+The third argument indicates the type of this menuitem. It is one of
+the following
+
+ * OPT_RUN : executable content
+ * OPT_EXITMENU : exits menu to parent
+ * OPT_SUBMENU : if selected, displays a submenu
+ * OPT_CHECKBOX : associates a boolean with this item which can be toggled
+ * OPT_RADIOMENU: associates this with a radio menu.
+      After execution, the data field of this item will point
+      to the option selected.
+ * OPT_SEP : A menu seperator (visually divide menu into parts)
+ * OPT_RADIOITEM: this item is one of the options in a RADIOMENU
+ * OPT_INACTIVE : A disabled item (user cannot select this)
+ * OPT_INVISIBLE: This item will not be displayed.
+
+The fourth argument is the value of the data field always a string.
+Usually this string is just copied and nothing is done with it. Two
+cases, where it is used.
+
+In case of a radiomenu the input string is ignored and the "data" field
+points to the menuitem chosen (Dont forget to typecast this pointer to
+(t_menuitem *) when reading this info).
+
+In case of a submenu, this string if non-trivial is interpreted as the
+name of the submenu which should be linked there. This interpretation
+happens when the menu is first run and not when the menu system is being
+created. This allows the user to create the menusystem in an arbitrary
+order.
+
+
+The fifth argument is a number whose meaning depends on the type of the
+item. For a CHECKBOX it should be 0/1 setting the initial state of the
+checkbox. For a SUBMENU it should be the index of the menu which should
+be displayed if this option is chosen. Incase the data field is non-trivial,
+this number is ignored and computed later. For a RADIOMENU it should be the
+index of the menu which contains all the options (All items in that menu
+not of type RADIOITEM are ignored). For all other types, this
+argument has no meaning at all.
+
+A call to add_sep is a convenient shorthand for calling add_item
+with the type set to OPT_SEP.
+
+1.3 Executing the menusystem
+----------------------------
+This is the simplest of all. Just call showmenus, with the index
+of the main menu as its argument. It returns a pointer to the menu
+item which was selected by the user.
+
+<code>
+   choice = showmenus(MAIN); // Initial menu is the one with index MAIN
+   // or choice = showmenus(find_menu_num("main")); // Initial menu is the one named "main"
+</code>
+
+1.4 Processing the result
+-------------------------
+This pointer will either be NULL (user hit Escape) or always point
+to a menuitem which can be "executed", i.e. it will be of type OPT_RUN.
+Usually at this point, all we need to do is to ask syslinux to run
+the command associated with this menuitem. The following code executes
+the command stored in choice->data (there is no other use for the data
+field, except for radiomenu's)
+
+<code>
+  if (choice)
+  {
+        if (choice->action == OPT_RUN)
+        {
+            if (syslinux) runcommand(choice->data);
+            else csprint(choice->data,0x07);
+            return 1;
+        }
+        csprint("Error in programming!",0x07);
+  }
+</code>
+
+2. Advanced features
+--------------------
+Everycall to add_item actually returns a pointer to the menuitem
+created. This can be useful when using any of the advanced features.
+
+2.1 extra_data
+--------------
+For example, every menuitem has an "extra_data" field (a pointer)
+which the user can use to point any data he/she pleases. The menusystem
+itself does not use this field in anyway.
+
+2.2 helpid
+----------
+Every item also has a field called "helpid". It is meant to hold some
+kind of identifier which can be referenced and used to generate
+a context sensitive help system. This can be set after a call to
+add_item as follows
+<code>
+  add_item("selfloop","Status 2",OPT_SUBMENU,NULL,MAINMENU);
+  set_item_options('A',4516);
+</code>
+
+The first is the shortcut key for this entry. You can put -1 to ensure
+that the shortcut key is not reset. The second is some unsigned integer.
+If this value is 0xFFFF, then the helpid is not changed.
+
+2.3 Installing global handlers
+------------------------------
+It is possible to register handlers for the menu system. These are
+user functions which are called by the menusystem in certain
+situations. Usually the handlers get a pointer to the menusystem
+datastructure as well as a pointer to the current item selected.
+Some handlers may get additional information. Some handlers are
+required to return values while others are not required to do so.
+
+Currently the menusystem support three types of global handlers
+* timeout handler
+* screen handler
+* keys handler
+
+2.3.1 timeout handler
+---------------------
+This is installed using a call to "reg_ontimeout(fn,numsteps,stepsize)"
+function. fn is a pointer to a function which takes no arguments and
+returns one of CODE_WAIT, CODE_ENTER, CODE_ESCAPE. This function is
+called when numsteps*stepsize Centiseconds have gone by without any
+user input. If the function returns CODE_WAIT then the menusystem
+waits for user input (for another numsteps*stepsize Centiseconds). If
+CODE_ENTER or CODE_ESCAPE is returned, then the system pretends that
+the user hit ENTER or ESCAPE on the keyboard and acts accordingly.
+
+2.3.2 Screen handler
+--------------------
+This is installed using a call to "reg_handler(HDLR_SCREEN,fn)". fn is
+a pointer to a function which takes a pointer to the menusystem
+datastructure and the current item selected and returns nothing.
+This is called everytime a menu is drawn (i.e. everytime user changes
+the current selection). This is meant for displaying any additional
+information which reflects the current state of the system.
+
+2.3.3 Keys handler
+------------------
+This is installed using a call to "reg_handler(HDLR_KEYS,fn)". fn is
+a pointer to a function which takes a pointer to the menusystem
+datastructure, the current item and the scan code of a key and returns
+nothing. This function is called when the user presses a key which
+the menusystem does not know to dealwith. In any case, when this call
+returns the screen should not have changed in any way. Usually,
+one can change the active page and display any output needed and
+reset the active page when you return from this call.
+
+complex.c implements a key_handler, which implements a simple
+context sensitive help system, by displaying the contents of a
+file whose name is based on the helpid of the active item.
+
+Also, complex.c's handler allows certain users to make changes
+to edit the commands associated with a menu item.
+
+2.4 Installing item level handlers
+----------------------------------
+In addition to global handlers, one can also install handlers for each
+individual item. A handler for an individual item is a function which
+takes a pointer to the menusystem datastructure and a pointer to the
+current item and return a structure of type t_handler_return. Currently
+it has two bit fields "valid" and "refresh".
+
+This handler is called when the user hits "enter" on a RUN item, or
+changes the status of a CHECKBOX, or called *after* a radio menu choice
+has been set. In all other cases, installing a handler has no effect.
+
+The handler can change any of the internal datastructures it pleases.
+For e.g. in a radiomenu handler, one can change the text displayed
+on the menuitem depending on which choice was selected (see complex.c
+for an example). The return values are ignored for RADIOMENU's.
+
+In case of RUN items: the return values are used as follows. If the
+return value of "valid" was false, then this user choice is ignored.
+This is useful if the handler has useful side effects. For e.g.
+complex.c has a Login item, whose handler always return INVALID. It
+sets a global variable to the name of the user logged in, and enables
+some menu items, and makes some invisible items visible.
+
+* If the handler does not change the visibility status of any items,
+  the handler should set "refresh" to 0.
+* If the handler changes the visibility status of items in the current
+  menu set "refresh" to 1.
+* If you are changing the visibility status of items in menu's currently
+  not displayed, then you can set "refresh" to 0.
+* Changing the visibility status of items in another menu
+  which is currently displayed, is not supported. If you do it,
+  the screen contents may not reflect the change until you get to the
+  menu which was changed. When you do get to that menu, you may notice
+  pieces of the old menu still on the screen.
+
+In case of CHECKBOXES: the return value of "valid" is ignored. Because,
+the handler can change the value of checkbox if the user selected value
+is not appropriate. only the value of "refresh" is honored. In this case
+all the caveats in the previous paragraph apply.
+
+menu.h defines two instances of t_handler_return
+ACTION_VALID and ACTION_INVALID for common use. These set the valid flag
+to 1 and 0 respectively and the refresh flag to 0.
+
+3. Things to look out for
+-------------------------
+When you define the menu system, always declare it in the opposite
+order, i.e. all lower level menu's should be defined before the higher
+level menus. This is because in order to define the MAINMENU, you need
+to know the index assigned to all its submenus.
+
+4. Additional Modules
+---------------------
+You can make use of the following additional modules, in writing your
+handlers.
+
+* Passwords
+* Help
+
+4.1 Passwords
+-------------
+This module was written by Th. Gebhardt. This is basically a modification
+of the DES crypt function obtained by removing the dependence of the
+original crypt function on C libraries. The following functions are
+defined
+
+  init_passwords(PWDFILE)
+      // Read in the password database from the file
+  authenticate_user(user,pwd)
+      // Checks if user,pwd is valid
+  isallowed(user,perm)
+      // Checks if the user has a specified permission
+  close_passwords()
+      // Unloads password database from memory
+
+  See the sample password file for more details about the file format
+  and the implementation of permissions.
+
+See complex.c for a example of how to use this.
+
+4.2 Help
+--------
+This can be used to set up a context sensitive help system. The following
+functions are defined
+
+   init_help(HELPBASEDIR)
+       // Initialises the help system. All help files will be loaded
+       // from the directory specified.
+   runhelpsystem(context)
+       // Displays the contents of HELPBASEDIR/hlp<context>.txt
+
+In order to have a functioning help system, you just need to create
+the hlp<NNNNN>.txt files and initialize the help system by specifying
+the base directory.
+
+The first line of this file assumed to be the title of the help screen.
+You can use ^N and ^O to change attributes absolutely and relatively,
+i.e. [^O]46 (i.e. Ctrl-O followed by chars 4 and 6) will set the
+attribute to 46, while [^N]08 will XOR the current attribute with
+specified number, thus in this case the first [^N]08 will turn on
+highlighting and the second one will turn it off.

+A .menu file can be used to describe basic menu structures which can be converted

+The format of a .menu file is similar to an ini file, but with important
+differences.
+
+Lines starting with # and ; are treated as comments. Blank lines are used to
+separate the attributes of one menu item from another. Multiple blank lines are
+equivalent to a single one.  In other contexts Blank lines are not significant.
+
+Menus
+-----
+Each menu declaration starts with a line containing the name of menu in [ ].
+This is the "nickname" of the menu and should be different for different menus.
+This is not visible to the user of the menu system. The initial menu must
+be called "main"
+
+The menu declaration is followed by lines which set the attributes of the menu.
+This is followed by a blank line and followed by declaration of menu items in
+that menu.
+
+All lines which occur before the first menu declaration is considered as
+a global declaration.
+
+Abstract Format
+---------------
+
+The overall format should look like this
+
+--------------------------------------------------------
+<GLOBAL SETTINGS>
+
+[menuname1]
+
+<MENU SETTINGS>
+
+<ITEM 1>
+
+...
+
+<ITEM N>
+
+[menuname2]
+
+<MENU SETTINGS>
+
+<ITEM A>
+
+<ITEM B>
+
+----------------------------------------------------------
+
+GLOBAL SETTINGS
+---------------
+The following global settings are now supported. Many of the keywords
+accept what we call a "DOT COMMAND" as argument. Simply put they are
+instructions to the menu system to perform certain actions.
+The syntax and semantics of DOT COMMANDS are given later in the section
+titled "DOT COMMANDS".
+
+videomode: (default 0xFF)  [Use with care]
+   The textmode in which the whole menu system should operate.
+   Must be a number (use 0x notation for hexadecimal).
+   Lookup Ralph Brown Interrupt List and search for Video Mode
+   to find a number to put here.
+
+   setting to 0xFF will mean, menu system will use the current
+   video mode.
+
+title:
+   The title of the whole menu system
+
+top, left, bot, right: (default 0,0,21,79)
+   The area of the screen used by the menu system. The remaining
+   part of the screen can be used by the user for anything.
+
+helpdir: (default /isolinux/help)
+   Location of the directory where help information is stored. The
+   help files must be called "hlpNNNNN.txt" where NNNNN is the helpid.
+
+pwdfile: (default /isolinux/passwd)
+   The name of the password file which contains user, password and permissions
+   See "passwd" file for details regarding format of this file
+
+editrow: (default 23)
+   the row on the screen where one can edit the command line. This must
+   be outside the menu area. Set this to a negative number to disable
+   editing the command line. In case of authenticated users, the current
+   user must have "editcmd" permissions to edit the command line
+
+pwdrow: (default 23)
+   The row on the screen used for user authentication. Must be outside
+   menu area (can be same as editrow). Set to negative to disable
+   user authentication
+
+skipif: (default 0)
+   The OR of the bits in the Shift-flags any of which can cause the menu system
+   to be skipped all together (0 means menu system always runs). It can also
+   be a combination of "Alt","Ctrl","Shift","Caps","Ins","Scroll".
+   When menu system starts it checks if any of the specified keys are On/pressed.
+   If true, the system exits immediately and executes the skipcmd.
+
+   e.g. setting it to "shift-alt-caps" means menu will be skipped if alt OR shift
+   is pressed OR caps is on. setting to "0" means menu will always run.
+
+skipcmd: (default .exit)
+   valid terminal commands: .exit .ignore or any syslinux command
+   command to execute if menu system is skipped. This must be a non-trivial
+   syslinux command if skipcondn is not "0". ".exit" means menu system
+   quits back to the boot prompt.
+
+startfile: (default "")
+   if non-empty the system will display the contents of this file before launching
+   the menusystem. This happens only if the menusystem is not skipped. Can be used
+   to display licensing, usage or welcome messages. A file with given name
+   is expected to be found in the helpdir directory.
+
+exitcmd: (default .exit)
+   valid terminal commands: .exit .repeat or any syslinux command
+   The default command to execute when user quits the menu system.
+
+exitcmdroot: (default =exitcmd)
+   Same as exitcmd except applies when current user has "root" privileges. If not
+   specified, it is assumed to be the same as exitcmd
+
+timeout: (default 3000)
+   The amount of time (in multiple of 0.1 seconds) to wait for user keypress. If no
+   key pressed for specified duration then the timeoutcmd is executed.
+
+totaltimeout: (default 0)
+   The total amount of time (in multiples of 0.1 seconds) the system will wait for
+   user to make a decision. If no decision has been made in the specified duration
+   totaltimeoutcmd will be executed
+
+   NOTE: This does not include the time spent browsing the help system or
+   the time taken for the user to enter his/her authentication credentials.
+
+timeoutcmd: (default .beep)
+   valid terminal commands: .wait .enter .escape or any syslinux command
+   command to execute when we timeout waiting for user input. The commands
+   .enter and .escape tell the menu system to pretend the user typed ENTER or
+   ESCAPE on the keyboard, while .wait tells the menusystem to wait for one
+   more time period
+
+totaltimeoutcmd: (default .wait)
+   choices are the same as for timeoutcmd
+
+MENU SETTINGS
+-------------
+
+title: (must be specified)
+   Title of this menu
+
+row,col: [Usage not recomended]
+   position in screen where this menu should be placed. By default the
+   system will choose an appropriate location.
+
+ITEM ATTRIBUTES
+---------------
+
+item:
+      The string displayed to the user. Characters enclosed in < > are highlighted.
+
+shortcut: (default -1) valid values A-Za-z0-9 or -1 [Usage not recommended]
+      Sets the shortcut key for this item. If set to -1, the system scans for the first
+      highlighted letter in the given range and sets that as the shortcut key.
+
+info: (default same as data)
+      Additional textual information displayed in the status bar
+
+type:
+      the type of entry this item represents. This is one of the following:
+
+      run:       choosing this will run something in SYSLINUX
+                 use data to specify the actual command to execute
+      exitmenu:  exit to parent menu
+      submenu:   choosing will open up submenu
+                 use data to specify the "nickname" of the menu
+                 which should come here
+      sep:       Position a separator here
+      inactive:  menu item is disabled
+      checkbox:  this is a checkbox
+                 use state to set initial state
+      invisible: User does not see this item
+      radioitem: One choice in a radiomenu
+      radiomenu: Allow user to choose one of many choices
+                 (initial choice is always NULL)
+      login:     Selecting this will allow user to login to system
+
+data:
+      for run items, the syslinux command to execute
+      for submenus and radiomenus, nickname of menu
+      for checkboxes, string to be added to kernel command line (if set)
+      for radioitems, string to be added to kernel command line (if chosen)
+
+ipappend:
+      ipappend flag to pass to PXELINUX (harmless for other variants of SYSLINUX)
+      See syslinux documentation for meaning of the FLAGS
+
+helpid: (default 65535 which is not a valid id)
+      associates a context for the help system.
+
+state: (default 0)
+      Initial state of a checkbox (for other items this has no meaning)
+
+perms: (default "")
+      string containing the name of the permission which user must
+      have to activate this item. For eg. if this item is a submenu
+      then user needs the permission in order to open the submenu
+
+argsmenu: (default "")
+      Name of the menu to be scanned for setting additional arguments to
+      pass to command line when this item is chosen for execution. Submenus
+      of specified menu are also scanned. Only checkboxes and radiomenu's
+      are scanned. Items of other type in this menu is silently ignored.
+
+
+DOT COMMANDS
+------------
+Dot commands are basically instructions to the menu system to do certain things.
+
+A "single command" is one of the following
+
+[NT] A syslinux command (any DOT command not starting with a "." is assumed to be this)
+[NT] .beep [n]
+[NT] .help <file>
+[NT] .nop
+[T]  .exit or .quit (equivalent)
+[T]  .repeat or .wait or .ignore (all three are equivalent)
+
+A dot command is a sequence of "single commands" separated by a "%". When a dot command
+is executed the system executes all the given "single commands" in the specified order.
+All the commands marked "[T]" are terminal commands, i.e. when the system encounters
+such a command it stops processing the dot command and returns the terminal command
+which caused the termination to the caller (who usually interprets the command
+appropriately).
+
+All commands marked with [NT] are non-terminal commands, i.e. once these commands are
+processed the system continues to process the remaining "single commands" specified in
+the "DOT COMMAND".
+
+Note: The case of a syslinux command is tricky. When executed, the command should never return
+(if the specified kernel exists) so the fact that we consider it a [NT] should be taken with
+a pinch of salt. However, if the syslinux command does return (in case of no kernel), then
+remaining "single commands" are processed. In particular "ker1 arg1 % ker2 arg2 % ker3 args"
+has the effect of executing the first kernel which exists
+
+.nop:
+   Does nothing.
+.beep:
+   .beep [n] produces a beep n times. n must be between 0 and 9. If not specified n=1.
+   (hence .beep 0 is equivalent to .nop)
+.help:
+   .help <file>
+   Displays the help file <file> which is assumed to be in the "help" directory. Its name
+   does not have to be in the form "hlpNNNNN.txt" (as required by the context sensitive help).
+   Executing this command will mean the appropriate help screen is displayed till the user hits
+   ESCAPE
+
+The meaning of the Terminal commands can vary with the context in which it is used. For example,
+a ".enter" or ".escape" does not have any meaning in the "onerrorcmd" context but it has a meaning
+in the "ontimeout" context. In case the user gives a Terminal command which does not make sense, it
+is upto the code (in this case adv_menu.tpl) to do what it pleases.

+          Text User Interface using comboot
+          ---------------------------------
+
+This is a menu system written by Murali Krishnan Ganapathy and ported
+from OpenWatcom to gcc by HPA. It is currently being maintained by the
+original author.
+
+To configure the menus, you need to set up a menu configuration file
+to have the menu items you desire, then build the menu system using
+make.  You can use either simple.c or complex.c as a starting point
+for your own menu configuration file; If your menu system is only going
+to have entries corresponding to things which can be executed directly,
+then you can create a file in ".menu" format instead of the C code.
+
+See MENU_FORMAT for the syntax of .menu files
+
+The resulting code is a 32-bit COMBOOT code, and hence can be executed
+only under syslinux. You can use tools like bochs to help debug your
+code.
+
+Menu Features currently supported are:
+* menu items,
+* submenus,
+* disabled items,
+* checkboxes,
+* invisible items (useful for dynamic menus), and
+* Radio menus,
+* Context sensitive help
+* Authenticated users
+* Editing commands associated with items
+
+The keys used are:
+
+* Arrow Keys, PgUp, PgDn, Home, End Keys
+* Space to switch state of a checkbox
+* Enter to choose the item
+* Escape to exit from it
+* Shortcut keys
+
+Features
+--------
+This is a general purpose menu system implemented using only BIOS calls,
+so it can be executed in a COMBOOT environment as well. It is highly
+customizable. Some features include:
+
+* Status line
+    Display any help information associated with each menu item.
+* Window
+    Specify a window within which the menu system draws all its menu's.
+    It is upto the user to ensure that the menu's fit within the window.
+* Positioning submenus
+    By default, each submenu is positioned just below the corresponding
+    entry of the parent menu. However, the user may position each menu
+    at a specific location of his choice. This is useful, when the menu's
+    have lots of options.
+* Registering handlers for each menu item
+    This is mainly used for checkboxes and radiomenu's, where a selection may
+    result in disabling other menu items/checkboxes
+* Global Screen Handler
+    This is called every time the menu is redrawn. The user can display
+    additional information (usually outside the window where the menu is
+    being displayed). See the complex.c for an example, where the global
+    handler is used to display the choices made so far.
+* Global Keys Handler
+    This is called every time the user presses a key which the menu
+    system does not understand. This can be used to display context
+    sensitive help. See complex.c for how to use this hook to implement
+    a context sensitive help system as well as "On the fly" editing
+    of commands associated with menus.
+* Shortcut Keys
+    With each item one can register a shortcut key from [A-Za-z0-9].
+    Pressing a key within that range, will take you to the next item
+    with that shortcut key (so you can have multiple items with the
+    same shortcut key). The default shortcut key for each item, is
+    the lower case version of the first char of the item in the range
+    [A-Za-z0-9].
+* Escape Keys
+    Each item entry can have a substring enclosed in < and >. This part
+    is highlighted. Can be used to highlight the shortcut keys. By default
+    if an item has a <, then the first char inside < and > in the range
+    [A-Za-z0-9] is converted to lower case and set as the shortcut key.
+* Ontimeout handler
+    The user can register an ontimeout handler, which gets called if
+    no key has been pressed for a user specific amount of time (default 5 min).
+    For an example see the complex.c file.

+All the lines in this file not in between --something BEGINS-- and --something ENDS--
+is ignored completely and will not make it into the generated C file
+
+This file has sections of C code each section delimited by --secname BEGINS--
+and --secname ENDS--. In the generated C code certain section may be used multiple
+times. Currently the different section which must be defined are
+
+header, system, item, login and footer
+
+Any additional sections you define will be processed but will probably not make it
+to the C code if you do not modify menugen.py to use it.
+
+header and footer go through unmolested. The remaining are % substituted using
+python rules. Basically it means %(var)s gets replaced by the value of the variable
+"var" which is a processed form of what is read from the .menu file
+
+NOTE: There is absolutely no C code in the python script, so you are free to
+modify this template to suit your needs

+ * An excellent reference on the underlying algorithm (and related

+ *	B. Schneier, Applied Cryptography: protocols, algorithms,
+ *	and source code in C, John Wiley & Sons, 1994.
+ *
+ * Note that in that book's description of DES the lookups for the initial,

+ *	It is assumed that the 8-byte arrays passed by reference can be
+ *	addressed as arrays of u_int32_t's (ie. the CPU is not picky about

+/* If no key is pressed within TIMEOUTNUMSTEPS * TIMEOUTSTEPSIZE milliseconds
+   and if a timeout handler is registered, then that will be called.
+   The handler should either either take control from there on, or return without
+   producing any change in the current video settings.
+
+   For e.g. the handler could
+   * Could just quit the menu program
+   * beep and return.
+
+   TIMEOUTSTEPSIZE is the interval for which the program sleeps without checking for
+   any keystroke. So increasing this will make the response of the system slow.
+   Decreasing this will make a lot of interrupt calls using up your CPU. Default
+   value of TIMEOUTSTEPSIZE of 0.1 seconds should be right in most cases.
+
+   TIMEOUTNUMSTEPS of 3000 corresponds to a wait time of 300 seconds or 5 minutes

+To build HDT, you just have to do a "make" call in this directory.
+
+---------------------------
+Creating a bootable floppy
+--------------------------
+To build a bootable HDT floppy image, you can do a "make hdt.img" call.
+This will requires the mtools (http://mtools.linux.lu) to be installed.
+The script will try to pick several files from your system :
+- /lib/modules/`uname -r`/modules.alias
+- /lib/modules/`uname -r`/modules.pcimap
+- /usr/share/pci.ids or /usr/share/hwdata/pci.ids
+
+This paths can be overrided with the following command line:
+make MODULES_ALIAS_FILE=$(PWD)/floppy/modules.alias MODULES_PCIMAP_FILE=$(PWD)/floppy/modules.pcimap PCI_IDS_FILE=$(PWD)/floppy/pci.ids hdt.img
+
+If your system doesn't have pci.ids, please download it from http://pciids.sourceforge.net/ and put it into the floppy/ directory.

+ *    Henceforth the source version will match the shared-library major

+ *    used for changes in backward compatibility, as it is intended.  The
+ *    PNG_LIBPNG_VER macro, which is not used within libpng but is available
+ *    for applications, is an unsigned integer of the form xyyzz corresponding
+ *    to the source version x.y.z (leading zeros in y and z).  Beta versions
+ *    were given the previous public release number plus a letter, until
+ *    version 1.0.6j; from then on they were given the upcoming public
+ *    release number plus "betaNN" or "rcNN".
+ *
+ *    Binary incompatibility exists only when applications make direct access
+ *    to the info_ptr or png_ptr members through png.h, and the compiled
+ *    application is loaded with a different version of the library.
+ *
+ *    DLLNUM will change each time there are forward or backward changes
+ *    in binary compatibility (e.g., when a new feature is added).
+ *
+ * See libpng.txt or libpng.3 for more information.  The PNG specification
+ * is available as a W3C Recommendation and as an ISO Specification,
+ * <http://www.w3.org/TR/2003/REC-PNG-20031110/

+ * Y2K compliance in libpng:
+ * =========================
+ *
+ *    June 26, 2010
+ *
+ *    Since the PNG Development group is an ad-hoc body, we can't make
+ *    an official declaration.
+ *
+ *    This is your unofficial assurance that libpng from version 0.71 and
+ *    upward through 1.2.44 are Y2K compliant.  It is my belief that earlier
+ *    versions were also Y2K compliant.
+ *
+ *    Libpng only has three year fields.  One is a 2-byte unsigned integer
+ *    that will hold years up to 65535.  The other two hold the date in text
+ *    format, and will hold years up to 9999.
+ *
+ *    The integer is
+ *        "png_uint_16 year" in png_time_struct.
+ *
+ *    The strings are
+ *        "png_charp time_buffer" in png_struct and
+ *        "near_time_buffer", which is a local character string in png.c.
+ *
+ *    There are seven time-related functions:
+ *        png.c: png_convert_to_rfc_1123() in png.c
+ *          (formerly png_convert_to_rfc_1152() in error)
+ *        png_convert_from_struct_tm() in pngwrite.c, called in pngwrite.c
+ *        png_convert_from_time_t() in pngwrite.c
+ *        png_get_tIME() in pngget.c
+ *        png_handle_tIME() in pngrutil.c, called in pngread.c
+ *        png_set_tIME() in pngset.c
+ *        png_write_tIME() in pngwutil.c, called in pngwrite.c
+ *
+ *    All handle dates properly in a Y2K environment.  The
+ *    png_convert_from_time_t() function calls gmtime() to convert from system
+ *    clock time, which returns (year - 1900), which we properly convert to
+ *    the full 4-digit year.  There is a possibility that applications using
+ *    libpng are not passing 4-digit years into the png_convert_to_rfc_1123()
+ *    function, or that they are incorrectly passing only a 2-digit year
+ *    instead of "year - 1900" into the png_convert_from_struct_tm() function,
+ *    but this is not under our control.  The libpng documentation has always
+ *    stated that it works with 4-digit years, and the APIs have been
+ *    documented as such.
+ *
+ *    The tIME chunk itself is also Y2K compliant.  It uses a 2-byte unsigned
+ *    integer to hold the year, and can hold years as large as 65535.
+ *
+ *    zlib, upon which libpng depends, is also Y2K compliant.  It contains
+ *    no date-related code.

+    The 'zlib' compression library provides in-memory compression and
+  decompression functions, including integrity checks of the uncompressed data.
+  This version of the library supports only one compression method (deflation)
+  but other algorithms will be added later and will have the same stream
+  interface.
+
+    Compression can be done in a single step if the buffers are large enough,
+  or can be done by repeated calls of the compression function.  In the latter
+  case, the application must provide more input and/or consume the output
+  (providing more output space) before each call.
+
+    The compressed data format used by default by the in-memory functions is
+  the zlib format, which is a zlib wrapper documented in RFC 1950, wrapped
+  around a deflate stream, which is itself documented in RFC 1951.
+
+    The library also supports reading and writing files in gzip (.gz) format
+  with an interface similar to that of stdio using the functions that start
+  with "gz".  The gzip format is different from the zlib format.  gzip is a
+  gzip wrapper, documented in RFC 1952, wrapped around a deflate stream.
+
+    This library can optionally read and write gzip streams in memory as well.
+
+    The zlib format was designed to be compact and fast for use in memory
+  and on communications channels.  The gzip format was designed for single-
+  file compression on file systems, has a larger header than zlib to maintain
+  directory information, and uses a different, slower check method than zlib.
+
+    The library does not install any signal handler.  The decoder checks
+  the consistency of the compressed data, so the library should never crash
+  even in case of corrupted input.

+/*
+    deflate compresses as much data as possible, and stops when the input
+  buffer becomes empty or the output buffer becomes full.  It may introduce
+  some output latency (reading input without producing any output) except when
+  forced to flush.
+
+    The detailed semantics are as follows.  deflate performs one or both of the
+  following actions:
+
+  - Compress more input starting at next_in and update next_in and avail_in
+    accordingly.  If not all input can be processed (because there is not
+    enough room in the output buffer), next_in and avail_in are updated and
+    processing will resume at this point for the next call of deflate().
+
+  - Provide more output starting at next_out and update next_out and avail_out
+    accordingly.  This action is forced if the parameter flush is non zero.
+    Forcing flush frequently degrades the compression ratio, so this parameter
+    should be set only when necessary (in interactive applications).  Some
+    output may be provided even if flush is not set.
+
+    Before the call of deflate(), the application should ensure that at least
+  one of the actions is possible, by providing more input and/or consuming more
+  output, and updating avail_in or avail_out accordingly; avail_out should
+  never be zero before the call.  The application can consume the compressed
+  output when it wants, for example when the output buffer is full (avail_out
+  == 0), or after each call of deflate().  If deflate returns Z_OK and with
+  zero avail_out, it must be called again after making room in the output
+  buffer because there might be more output pending.
+
+    Normally the parameter flush is set to Z_NO_FLUSH, which allows deflate to
+  decide how much data to accumulate before producing output, in order to
+  maximize compression.
+
+    If the parameter flush is set to Z_SYNC_FLUSH, all pending output is
+  flushed to the output buffer and the output is aligned on a byte boundary, so
+  that the decompressor can get all input data available so far.  (In
+  particular avail_in is zero after the call if enough output space has been
+  provided before the call.) Flushing may degrade compression for some
+  compression algorithms and so it should be used only when necessary.  This
+  completes the current deflate block and follows it with an empty stored block
+  that is three bits plus filler bits to the next byte, followed by four bytes
+  (00 00 ff ff).
+
+    If flush is set to Z_PARTIAL_FLUSH, all pending output is flushed to the
+  output buffer, but the output is not aligned to a byte boundary.  All of the
+  input data so far will be available to the decompressor, as for Z_SYNC_FLUSH.
+  This completes the current deflate block and follows it with an empty fixed
+  codes block that is 10 bits long.  This assures that enough bytes are output
+  in order for the decompressor to finish the block before the empty fixed code
+  block.
+
+    If flush is set to Z_BLOCK, a deflate block is completed and emitted, as
+  for Z_SYNC_FLUSH, but the output is not aligned on a byte boundary, and up to
+  seven bits of the current block are held to be written as the next byte after
+  the next deflate block is completed.  In this case, the decompressor may not
+  be provided enough bits at this point in order to complete decompression of
+  the data provided so far to the compressor.  It may need to wait for the next
+  block to be emitted.  This is for advanced applications that need to control
+  the emission of deflate blocks.
+
+    If flush is set to Z_FULL_FLUSH, all output is flushed as with
+  Z_SYNC_FLUSH, and the compression state is reset so that decompression can
+  restart from this point if previous compressed data has been damaged or if
+  random access is desired.  Using Z_FULL_FLUSH too often can seriously degrade
+  compression.
+
+    If deflate returns with avail_out == 0, this function must be called again
+  with the same value of the flush parameter and more output space (updated
+  avail_out), until the flush is complete (deflate returns with non-zero
+  avail_out).  In the case of a Z_FULL_FLUSH or Z_SYNC_FLUSH, make sure that
+  avail_out is greater than six to avoid repeated flush markers due to
+  avail_out == 0 on return.
+
+    If the parameter flush is set to Z_FINISH, pending input is processed,
+  pending output is flushed and deflate returns with Z_STREAM_END if there was
+  enough output space; if deflate returns with Z_OK, this function must be
+  called again with Z_FINISH and more output space (updated avail_out) but no
+  more input data, until it returns with Z_STREAM_END or an error.  After
+  deflate has returned Z_STREAM_END, the only possible operations on the stream
+  are deflateReset or deflateEnd.
+
+    Z_FINISH can be used immediately after deflateInit if all the compression
+  is to be done in a single step.  In this case, avail_out must be at least the
+  value returned by deflateBound (see below).  If deflate does not return
+  Z_STREAM_END, then it must be called again as described above.
+
+    deflate() sets strm->adler to the adler32 checksum of all input read
+  so far (that is, total_in bytes).
+

+ZEXTERN int ZEXPORT inflate OF((z_streamp strm, int flush));
+/*
+    inflate decompresses as much data as possible, and stops when the input
+  buffer becomes empty or the output buffer becomes full.  It may introduce
+  some output latency (reading input without producing any output) except when
+  forced to flush.
+
+  The detailed semantics are as follows.  inflate performs one or both of the
+  following actions:
+
+  - Decompress more input starting at next_in and update next_in and avail_in
+    accordingly.  If not all input can be processed (because there is not
+    enough room in the output buffer), next_in is updated and processing will
+    resume at this point for the next call of inflate().
+
+  - Provide more output starting at next_out and update next_out and avail_out
+    accordingly.  inflate() provides as much output as possible, until there is
+    no more input data or no more space in the output buffer (see below about
+    the flush parameter).
+
+    Before the call of inflate(), the application should ensure that at least
+  one of the actions is possible, by providing more input and/or consuming more
+  output, and updating the next_* and avail_* values accordingly.  The
+  application can consume the uncompressed output when it wants, for example
+  when the output buffer is full (avail_out == 0), or after each call of
+  inflate().  If inflate returns Z_OK and with zero avail_out, it must be
+  called again after making room in the output buffer because there might be
+  more output pending.
+
+    The flush parameter of inflate() can be Z_NO_FLUSH, Z_SYNC_FLUSH, Z_FINISH,
+  Z_BLOCK, or Z_TREES.  Z_SYNC_FLUSH requests that inflate() flush as much
+  output as possible to the output buffer.  Z_BLOCK requests that inflate()
+  stop if and when it gets to the next deflate block boundary.  When decoding
+  the zlib or gzip format, this will cause inflate() to return immediately
+  after the header and before the first block.  When doing a raw inflate,
+  inflate() will go ahead and process the first block, and will return when it
+  gets to the end of that block, or when it runs out of data.
+
+    The Z_BLOCK option assists in appending to or combining deflate streams.
+  Also to assist in this, on return inflate() will set strm->data_type to the
+  number of unused bits in the last byte taken from strm->next_in, plus 64 if
+  inflate() is currently decoding the last block in the deflate stream, plus
+  128 if inflate() returned immediately after decoding an end-of-block code or
+  decoding the complete header up to just before the first byte of the deflate
+  stream.  The end-of-block will not be indicated until all of the uncompressed
+  data from that block has been written to strm->next_out.  The number of
+  unused bits may in general be greater than seven, except when bit 7 of
+  data_type is set, in which case the number of unused bits will be less than
+  eight.  data_type is set as noted here every time inflate() returns for all
+  flush options, and so can be used to determine the amount of currently
+  consumed input in bits.
+
+    The Z_TREES option behaves as Z_BLOCK does, but it also returns when the
+  end of each deflate block header is reached, before any actual data in that
+  block is decoded.  This allows the caller to determine the length of the
+  deflate block header for later use in random access within a deflate block.
+  256 is added to the value of strm->data_type when inflate() returns
+  immediately after reaching the end of the deflate block header.
+
+    inflate() should normally be called until it returns Z_STREAM_END or an
+  error.  However if all decompression is to be performed in a single step (a
+  single call of inflate), the parameter flush should be set to Z_FINISH.  In
+  this case all pending input is processed and all pending output is flushed;
+  avail_out must be large enough to hold all the uncompressed data.  (The size
+  of the uncompressed data may have been saved by the compressor for this
+  purpose.) The next operation on this stream must be inflateEnd to deallocate
+  the decompression state.  The use of Z_FINISH is never required, but can be
+  used to inform inflate that a faster approach may be used for the single
+  inflate() call.
+
+     In this implementation, inflate() always flushes as much output as
+  possible to the output buffer, and always uses the faster approach on the
+  first call.  So the only effect of the flush parameter in this implementation
+  is on the return value of inflate(), as noted below, or when it returns early
+  because Z_BLOCK or Z_TREES is used.
+
+     If a preset dictionary is needed after this call (see inflateSetDictionary
+  below), inflate sets strm->adler to the adler32 checksum of the dictionary
+  chosen by the compressor and returns Z_NEED_DICT; otherwise it sets
+  strm->adler to the adler32 checksum of all output produced so far (that is,
+  total_out bytes) and returns Z_OK, Z_STREAM_END or an error code as described
+  below.  At the end of the stream, inflate() checks that its computed adler32
+  checksum is equal to that saved by the compressor and returns Z_STREAM_END
+  only if the checksum is correct.
+
+    inflate() can decompress and check either zlib-wrapped or gzip-wrapped
+  deflate data.  The header type is detected automatically, if requested when
+  initializing with inflateInit2().  Any information contained in the gzip
+  header is not retained, so applications that need that information should
+  instead use raw inflate, see inflateInit2() below, or inflateBack() and
+  perform their own processing of the gzip header and trailer.
+
+    inflate() returns Z_OK if some progress has been made (more input processed
+  or more output produced), Z_STREAM_END if the end of the compressed data has
+  been reached and all uncompressed output has been produced, Z_NEED_DICT if a
+  preset dictionary is needed at this point, Z_DATA_ERROR if the input data was
+  corrupted (input stream not conforming to the zlib format or incorrect check
+  value), Z_STREAM_ERROR if the stream structure was inconsistent (for example
+  next_in or next_out was Z_NULL), Z_MEM_ERROR if there was not enough memory,
+  Z_BUF_ERROR if no progress is possible or if there was not enough room in the
+  output buffer when Z_FINISH is used.  Note that Z_BUF_ERROR is not fatal, and
+  inflate() can be called again with more input and more output space to
+  continue decompressing.  If Z_DATA_ERROR is returned, the application may
+  then call inflateSync() to look for a good compression block if a partial
+  recovery of the data is desired.

+
+     This is another version of deflateInit with more compression options.  The
+   fields next_in, zalloc, zfree and opaque must be initialized before by the
+   caller.
+
+     The method parameter is the compression method.  It must be Z_DEFLATED in
+   this version of the library.
+
+     The windowBits parameter is the base two logarithm of the window size
+   (the size of the history buffer).  It should be in the range 8..15 for this
+   version of the library.  Larger values of this parameter result in better
+   compression at the expense of memory usage.  The default value is 15 if
+   deflateInit is used instead.
+
+     windowBits can also be -8..-15 for raw deflate.  In this case, -windowBits
+   determines the window size.  deflate() will then generate raw deflate data
+   with no zlib header or trailer, and will not compute an adler32 check value.
+
+     windowBits can also be greater than 15 for optional gzip encoding.  Add
+   16 to windowBits to write a simple gzip header and trailer around the
+   compressed data instead of a zlib wrapper.  The gzip header will have no
+   file name, no extra data, no comment, no modification time (set to zero), no
+   header crc, and the operating system will be set to 255 (unknown).  If a
+   gzip stream is being written, strm->adler is a crc32 instead of an adler32.
+
+     The memLevel parameter specifies how much memory should be allocated
+   for the internal compression state.  memLevel=1 uses minimum memory but is
+   slow and reduces compression ratio; memLevel=9 uses maximum memory for
+   optimal speed.  The default value is 8.  See zconf.h for total memory usage
+   as a function of windowBits and memLevel.
+
+     The strategy parameter is used to tune the compression algorithm.  Use the
+   value Z_DEFAULT_STRATEGY for normal data, Z_FILTERED for data produced by a
+   filter (or predictor), Z_HUFFMAN_ONLY to force Huffman encoding only (no
+   string match), or Z_RLE to limit match distances to one (run-length
+   encoding).  Filtered data consists mostly of small values with a somewhat
+   random distribution.  In this case, the compression algorithm is tuned to
+   compress them better.  The effect of Z_FILTERED is to force more Huffman
+   coding and less string matching; it is somewhat intermediate between
+   Z_DEFAULT_STRATEGY and Z_HUFFMAN_ONLY.  Z_RLE is designed to be almost as
+   fast as Z_HUFFMAN_ONLY, but give better compression for PNG image data.  The
+   strategy parameter only affects the compression ratio but not the
+   correctness of the compressed output even if it is not set appropriately.
+   Z_FIXED prevents the use of dynamic Huffman codes, allowing for a simpler
+   decoder for special applications.
+
+     deflateInit2 returns Z_OK if success, Z_MEM_ERROR if there was not enough
+   memory, Z_STREAM_ERROR if any parameter is invalid (such as an invalid

+     inflateBack() does a raw inflate with a single call using a call-back
+   interface for input and output.  This is more efficient than inflate() for
+   file i/o applications in that it avoids copying between the output and the
+   sliding window by simply making the window itself the output buffer.  This
+   function trusts the application to not change the output buffer passed by
+   the output function, at least until inflateBack() returns.
+
+     inflateBackInit() must be called first to allocate the internal state
+   and to initialize the state with the user-provided window buffer.
+   inflateBack() may then be used multiple times to inflate a complete, raw
+   deflate stream with each call.  inflateBackEnd() is then called to free the
+   allocated state.
+
+     A raw deflate stream is one with no zlib or gzip header or trailer.
+   This routine would normally be used in a utility that reads zip or gzip
+   files and writes out uncompressed files.  The utility would decode the
+   header and process the trailer on its own, hence this routine expects only
+   the raw deflate stream to decompress.  This is different from the normal
+   behavior of inflate(), which expects either a zlib or gzip header and
+   trailer around the deflate stream.
+
+     inflateBack() uses two subroutines supplied by the caller that are then
+   called by inflateBack() for input and output.  inflateBack() calls those
+   routines until it reads a complete deflate stream and writes out all of the
+   uncompressed data, or until it encounters an error.  The function's
+   parameters and return types are defined above in the in_func and out_func
+   typedefs.  inflateBack() will call in(in_desc, &buf) which should return the
+   number of bytes of provided input, and a pointer to that input in buf.  If
+   there is no input available, in() must return zero--buf is ignored in that
+   case--and inflateBack() will return a buffer error.  inflateBack() will call
+   out(out_desc, buf, len) to write the uncompressed data buf[0..len-1].  out()
+   should return zero on success, or non-zero on failure.  If out() returns
+   non-zero, inflateBack() will return with an error.  Neither in() nor out()
+   are permitted to change the contents of the window provided to
+   inflateBackInit(), which is also the buffer that out() uses to write from.
+   The length written by out() will be at most the window size.  Any non-zero
+   amount of input may be provided by in().
+
+     For convenience, inflateBack() can be provided input on the first call by
+   setting strm->next_in and strm->avail_in.  If that input is exhausted, then
+   in() will be called.  Therefore strm->next_in must be initialized before
+   calling inflateBack().  If strm->next_in is Z_NULL, then in() will be called
+   immediately for input.  If strm->next_in is not Z_NULL, then strm->avail_in
+   must also be initialized, and then if strm->avail_in is not zero, input will
+   initially be taken from strm->next_in[0 ..  strm->avail_in - 1].
+
+     The in_desc and out_desc parameters of inflateBack() is passed as the
+   first parameter of in() and out() respectively when they are called.  These
+   descriptors can be optionally used to pass any information that the caller-
+   supplied in() and out() functions need to do their job.
+
+     On return, inflateBack() will set strm->next_in and strm->avail_in to
+   pass back any unused input that was provided by the last in() call.  The
+   return values of inflateBack() can be Z_STREAM_END on success, Z_BUF_ERROR
+   if in() or out() returned an error, Z_DATA_ERROR if there was a format error
+   in the deflate stream (in which case strm->msg is set to indicate the nature
+   of the error), or Z_STREAM_ERROR if the stream was not properly initialized.
+   In the case of Z_BUF_ERROR, an input or output error can be distinguished
+   using strm->next_in which will be Z_NULL only if in() returned an error.  If
+   strm->next_in is not Z_NULL, then the Z_BUF_ERROR was due to out() returning
+   non-zero.  (in() will always be called before out(), so strm->next_in is
+   assured to be defined if out() returns non-zero.) Note that inflateBack()

+ *
+ * This file contains a floating-point implementation of the
+ * inverse DCT (Discrete Cosine Transform).  In the IJG code, this routine
+ * must also perform dequantization of the input coefficients.
+ *
+ * This implementation should be more accurate than either of the integer
+ * IDCT implementations.  However, it may not give the same results on all
+ * machines because of differences in roundoff behavior.  Speed will depend
+ * on the hardware's floating point capacity.
+ *
+ * A 2-D IDCT can be done by 1-D IDCT on each column followed by 1-D IDCT
+ * on each row (or vice versa, but it's more convenient to emit a row at
+ * a time).  Direct algorithms are also available, but they are much more
+ * complex and seem not to be any faster when reduced to code.
+ *
+ * This implementation is based on Arai, Agui, and Nakajima's algorithm for
+ * scaled DCT.  Their original paper (Trans. IEICE E-71(11):1095) is in
+ * Japanese, but the algorithm is described in the Pennebaker & Mitchell
+ * JPEG textbook (see REFERENCES section in file README).  The following code
+ * is based directly on figure 4-8 in P&M.
+ * While an 8-point DCT cannot be done in less than 11 multiplies, it is
+ * possible to arrange the computation so that many of the multiplies are
+ * simple scalings of the final outputs.  These multiplies can then be
+ * folded into the multiplications or divisions by the JPEG quantization
+ * table entries.  The AA&N method leaves only 5 multiplies and 29 adds
+ * to be done in the DCT itself.
+ * The primary disadvantage of this method is that with a fixed-point
+ * implementation, accuracy is lost due to imprecise representation of the
+ * scaled quantization values.  However, that problem does not arise if
+ * we use floating point arithmetic.

+
+version 0.81 [August, 1995]
+  incorporated Tim Wegner's medium model code (thanks, Tim)
+
+version 0.82 [September, 1995]
+  [unspecified changes]
+
+version 0.85 [December, 1995]
+  added more medium model code (almost everything's a far)
+  added i/o, error, and memory callback functions
+  fixed some bugs (16 bit, 4 bit interlaced, etc.)
+  added first run progressive reader (barely tested)
+
+version 0.86 [January, 1996]
+  fixed bugs
+  improved documentation
+
+version 0.87 [January, 1996]
+  fixed medium model bugs
+  fixed other bugs introduced in 0.85 and 0.86
+  added some minor documentation
+
+version 0.88 [January, 1996]
+  fixed progressive bugs
+  replaced tabs with spaces
+  cleaned up documentation
+  added callbacks for read/write and warning/error functions
+
+version 0.89 [July, 1996]
+  added new initialization API to make libpng work better with shared libs
+     we now have png_create_read_struct(), png_create_write_struct(),
+     png_create_info_struct(), png_destroy_read_struct(), and
+     png_destroy_write_struct() instead of the separate calls to
+     malloc and png_read_init(), png_info_init(), and png_write_init()
+  changed warning/error callback functions to fix bug - this means you
+     should use the new initialization API if you were using the old
+     png_set_message_fn() calls, and that the old API no longer exists
+     so that people are aware that they need to change their code
+  changed filter selection API to allow selection of multiple filters
+     since it didn't work in previous versions of libpng anyways
+  optimized filter selection code
+  fixed png_set_background() to allow using an arbitrary RGB color for
+     paletted images
+  fixed gamma and background correction for paletted images, so
+     png_correct_palette is not needed unless you are correcting an
+     external palette (you will need to #define PNG_CORRECT_PALETTE_SUPPORTED
+     in pngconf.h) - if nobody uses this, it may disappear in the future.
+  fixed bug with Borland 64K memory allocation (Alexander Lehmann)
+  fixed bug in interlace handling (Smarasderagd, I think)
+  added more error checking for writing and image to reduce invalid files
+  separated read and write functions so that they won't both be linked
+     into a binary when only reading or writing functionality is used
+  new pngtest image also has interlacing and zTXt
+  updated documentation to reflect new API
+
+version 0.90 [January, 1997]
+  made CRC errors/warnings on critical and ancillary chunks configurable
+  libpng will use the zlib CRC routines by (compile-time) default
+  changed DOS small/medium model memory support - needs zlib 1.04 (Tim Wegner)
+  added external C++ wrapper statements to png.h (Gilles Dauphin)
+  allow PNG file to be read when some or all of file signature has already
+     been read from the beginning of the stream.  ****This affects the size
+     of info_struct and invalidates all programs that use a shared libpng****
+  fixed png_filler() declarations
+  fixed? background color conversions
+  fixed order of error function pointers to match documentation
+  current chunk name is now available in png_struct to reduce the number
+     of nearly identical error messages (will simplify multi-lingual
+     support when available)
+  try to get ready for unknown-chunk callback functions:
+     - previously read critical chunks are flagged, so the chunk handling
+       routines can determine if the chunk is in the right place
+     - all chunk handling routines have the same prototypes, so we will
+       be able to handle all chunks via a callback mechanism
+  try to fix Linux "setjmp" buffer size problems
+  removed png_large_malloc, png_large_free, and png_realloc functions.
+
+version 0.95 [March, 1997]
+  fixed bug in pngwutil.c allocating "up_row" twice and "avg_row" never
+  fixed bug in PNG file signature compares when start != 0
+  changed parameter type of png_set_filler(...filler...) from png_byte
+     to png_uint_32
+  added test for MACOS to ensure that both math.h and fp.h are not #included
+  added macros for libpng to be compiled as a Windows DLL (Andreas Kupries)
+  added "packswap" transformation, which changes the endianness of
+     packed-pixel bytes (Kevin Bracey)
+  added "strip_alpha" transformation, which removes the alpha channel of
+     input images without using it (not necessarily a good idea)
+  added "swap_alpha" transformation, which puts the alpha channel in front
+     of the color bytes instead of after
+  removed all implicit variable tests which assume NULL == 0 (I think)
+  changed several variables to "png_size_t" to show 16/32-bit limitations
+  added new pCAL chunk read/write support
+  added experimental filter selection weighting (Greg Roelofs)
+  removed old png_set_rgbx() and png_set_xrgb() functions that have been
+     obsolete for about 2 years now (use png_set_filler() instead)
+  added macros to read 16- and 32-bit ints directly from buffer, to be
+     used only on those systems that support it (namely PowerPC and 680x0)
+     With some testing, this may become the default for MACOS/PPC systems.
+  only calculate CRC on data if we are going to use it
+  added macros for zTXt compression type PNG_zTXt_COMPRESSION_???
+  added macros for simple libpng debugging output selectable at compile time
+  removed PNG_READ_END_MODE in progressive reader (Smarasderagd)
+  more description of info_struct in libpng.txt and png.h
+  more instructions in example.c
+  more chunk types tested in pngtest.c
+  renamed pngrcb.c to pngset.c, and all png_read_<chunk> functions to be
+     png_set_<chunk>.  We now have corresponding png_get_<chunk>
+     functions in pngget.c to get information in info_ptr.  This isolates
+     the application from the internal organization of png_info_struct
+     (good for shared library implementations).

+  tested NODIV support and made it default behaviour (Greg Roelofs)
+  added "-m" option and PNGTEST_DEBUG_MEMORY to pngtest (John Bowler)

+  free info_ptr->text instead of end_info_ptr->text in pngread.c (John Bowler)
+  fixed a longstanding "packswap" bug in pngtrans.c
+  fixed some inconsistencies in pngconf.h that prevented compiling with
+     PNG_READ_GAMMA_SUPPORTED and PNG_READ_hIST_SUPPORTED undefined
+  fixed some typos and made other minor rearrangement of libpng.txt (Andreas)
+  changed recommendation about file_gamma for PC images to .50 from .51 in

+    a helpful compiler error if an old png.h is found in the search path.
+  Changed type of png_user_transform_depth|channels from int to png_byte.
+version 1.0.4d [October 6, 1999]

+  Further optimization and bugfix of pngvcrd.c
+  Revised pngset.c so that it does not allocate or free memory in the user's
+    text_ptr structure.  Instead, it makes its own copy.
+  Created separate write_end_info_struct in pngtest.c for a more severe test.
+  Added code in pngwrite.c to free info_ptr->text[i].key to stop a memory leak.
+version 1.0.5b [November 23, 1999]
+  Moved PNG_FLAG_HAVE_CHUNK_HEADER, PNG_FLAG_BACKGROUND_IS_GRAY and

+    eliminated use of png_sig in pngwutil.c.  Moved the various png_CHNK arrays
+    into pngtypes.h.  Eliminated use of global png_pass arrays.  Declared the
+    png_CHNK and png_pass arrays to be "const".  Made the global arrays
+    available to applications (although none are used in libpng itself) when
+    PNG_NO_GLOBAL_ARRAYS is not defined or when PNG_GLOBAL_ARRAYS is defined.
+  Removed some extraneous "-I" from contrib/pngminus/makefile.std
+  Changed the PNG_sRGB_INTENT macros in png.h to be consistent with PNG-1.2.
+  Change PNG_SRGB_INTENT to PNG_sRGB_INTENT in libpng.txt and libpng.3
+version 1.0.5d [November 29, 1999]
+  Add type cast (png_const_charp) two places in png.c
+  Eliminated pngtypes.h; use macros instead to declare PNG_CHNK arrays.
+  Renamed "PNG_GLOBAL_ARRAYS" to "PNG_USE_GLOBAL_ARRAYS" and made available
+    to applications a macro "PNG_USE_LOCAL_ARRAYS".
+  Remove all the new declarations with #ifdef/#endif when
+    PNG_USE_GLOBAL_ARRAYS is defined.
+  Added PNG_EXPORT_VAR macro to accommodate making DLL's.
+version 1.0.5e [November 30, 1999]
+  Added iCCP, iTXt, and sPLT support; added "lang" member to the png_text
+    structure; refactored the inflate/deflate support to make adding new chunks
+    with trailing compressed parts easier in the future, and added new functions
+    png_free_iCCP, png_free_pCAL, png_free_sPLT, png_free_text, png_get_iCCP,
+    png_get_spalettes, png_set_iCCP, png_set_spalettes (Eric S. Raymond).
+  NOTE: Applications that write text chunks MUST define png_text->lang
+    before calling png_set_text(). It must be set to NULL if you want to
+    write tEXt or zTXt chunks.  If you want your application to be able to
+    run with older versions of libpng, use
+
+      #ifdef PNG_iTXt_SUPPORTED
+         png_text[i].lang = NULL;
+      #endif
+
+  Changed png_get_oFFs() and png_set_oFFs() to use signed rather than unsigned
+    offsets (Eric S. Raymond).
+  Combined PNG_READ_cHNK_SUPPORTED and PNG_WRITE_cHNK_SUPPORTED macros into
+    PNG_cHNK_SUPPORTED and combined the three types of PNG_text_SUPPORTED
+    macros, leaving the separate macros also available.
+  Removed comments on #endifs at the end of many short, non-nested #if-blocks.
+version 1.0.5f [December 6, 1999]
+  Changed makefile.solaris to issue a warning about potential problems when
+    the ucb "ld" is in the path ahead of the ccs "ld".
+  Removed "- [date]" from the "synopsis" line in libpng.3 and libpngpf.3.
+  Added sCAL chunk support (Eric S. Raymond).
+version 1.0.5g [December 7, 1999]
+  Fixed "png_free_spallettes" typo in png.h
+  Added code to handle new chunks in pngpread.c
+  Moved PNG_CHNK string macro definitions outside of PNG_NO_EXTERN block
+  Added "translated_key" to png_text structure and png_write_iTXt().
+  Added code in pngwrite.c to work around a newly discovered zlib bug.
+version 1.0.5h [December 10, 1999]
+  NOTE: regarding the note for version 1.0.5e, the following must also
+    be included in your code:
+        png_text[i].translated_key = NULL;
+  Unknown chunk handling is now supported.
+  Option to eliminate all floating point support was added.  Some new
+    fixed-point functions such as png_set_gAMA_fixed() were added.
+  Expanded tabs and removed trailing blanks in source files.
+version 1.0.5i [December 13, 1999]
+  Added some type casts to silence compiler warnings.
+  Renamed "png_free_spalette" to "png_free_spalettes" for consistency.
+  Removed leading blanks from a #define in pngvcrd.c
+  Added some parameters to the new png_set_keep_unknown_chunks() function.
+  Added a test for up->location != 0 in the first instance of writing
+    unknown chunks in pngwrite.c
+  Changed "num" to "i" in png_free_spalettes() and png_free_unknowns() to
+    prevent recursion.
+  Added png_free_hIST() function.
+  Various patches to fix bugs in the sCAL and integer cHRM processing,
+    and to add some convenience macros for use with sCAL.
+version 1.0.5j [December 21, 1999]
+  Changed "unit" parameter of png_write_sCAL from png_byte to int, to work
+    around buggy compilers.
+  Added new type "png_fixed_point" for integers that hold float*100000 values
+  Restored backward compatibility of tEXt/zTXt chunk processing:
+    Restored the first four members of png_text to the same order as v.1.0.5d.
+    Added members "lang_key" and "itxt_length" to png_text struct.  Set
+    text_length=0 when "text" contains iTXt data.  Use the "compression"
+    member to distinguish among tEXt/zTXt/iTXt types.  Added
+    PNG_ITXT_COMPRESSION_NONE (1) and PNG_ITXT_COMPRESSION_zTXt(2) macros.
+    The "Note" above, about backward incompatibility of libpng-1.0.5e, no
+    longer applies.
+  Fixed png_read|write_iTXt() to read|write parameters in the right order,
+    and to write the iTXt chunk after IDAT if it appears in the end_ptr.
+  Added pnggccrd.c, version of pngvcrd.c Intel assembler for gcc (Greg Roelofs)
+  Reversed the order of trying to write floating-point and fixed-point gAMA.
+version 1.0.5k [December 27, 1999]
+  Added many parentheses, e.g., "if (a && b & c)" becomes "if (a && (b & c))"
+  Added png_handle_as_unknown() function (Glenn)
+  Added png_free_chunk_list() function and chunk_list and num_chunk_list members
+    of png_ptr.
+  Eliminated erroneous warnings about multiple sPLT chunks and sPLT-after-PLTE.
+  Fixed a libpng-1.0.5h bug in pngrutil.c that was issuing erroneous warnings
+    about ignoring incorrect gAMA with sRGB (gAMA was in fact not ignored)
+  Added png_free_tRNS(); png_set_tRNS() now malloc's its own trans array (ESR).
+  Define png_get_int_32 when oFFs chunk is supported as well as when pCAL is.
+  Changed type of proflen from png_int_32 to png_uint_32 in png_get_iCCP().
+version 1.0.5l [January 1, 2000]
+  Added functions png_set_read_user_chunk_fn() and png_get_user_chunk_ptr()
+    for setting a callback function to handle unknown chunks and for
+    retrieving the associated user pointer (Glenn).
+version 1.0.5m [January 7, 2000]
+  Added high-level functions png_read_png(), png_write_png(), png_free_pixels().
+version 1.0.5n [January 9, 2000]
+  Added png_free_PLTE() function, and modified png_set_PLTE() to malloc its
+    own memory for info_ptr->palette.  This makes it safe for the calling
+    application to free its copy of the palette any time after it calls
+    png_set_PLTE().
+version 1.0.5o [January 20, 2000]
+  Cosmetic changes only (removed some trailing blanks and TABs)
+version 1.0.5p [January 31, 2000]
+  Renamed pngdll.mak to makefile.bd32
+  Cosmetic changes in pngtest.c
+version 1.0.5q [February 5, 2000]
+  Relocated the makefile.solaris warning about PATH problems.
+  Fixed pngvcrd.c bug by pushing/popping registers in mmxsupport (Bruce Oberg)
+  Revised makefile.gcmmx
+  Added PNG_SETJMP_SUPPORTED, PNG_SETJMP_NOT_SUPPORTED, and PNG_ABORT() macros
+version 1.0.5r [February 7, 2000]
+  Removed superfluous prototype for png_get_itxt from png.h
+  Fixed a bug in pngrtran.c that improperly expanded the background color.
+  Return *num_text=0 from png_get_text() when appropriate, and fix documentation
+    of png_get_text() in libpng.txt/libpng.3.
+version 1.0.5s [February 18, 2000]
+  Added "png_jmp_env()" macro to pngconf.h, to help people migrate to the
+    new error handler that's planned for the next libpng release, and changed
+    example.c, pngtest.c, and contrib programs to use this macro.
+  Revised some of the DLL-export macros in pngconf.h (Greg Roelofs)
+  Fixed a bug in png_read_png() that caused it to fail to expand some images
+    that it should have expanded.
+  Fixed some mistakes in the unused and undocumented INCH_CONVERSIONS functions
+    in pngget.c
+  Changed the allocation of palette, history, and trans arrays back to
+    the version 1.0.5 method (linking instead of copying) which restores
+    backward compatibility with version 1.0.5.  Added some remarks about
+    that in example.c.  Added "free_me" member to info_ptr and png_ptr
+    and added png_free_data() function.
+  Updated makefile.linux and makefile.gccmmx to make directories conditionally.
+  Made cosmetic changes to pngasmrd.h
+  Added png_set_rows() and png_get_rows(), for use with png_read|write_png().
+  Modified png_read_png() to allocate info_ptr->row_pointers only if it
+    hasn't already been allocated.
+version 1.0.5t [March 4, 2000]
+  Changed png_jmp_env() migration aiding macro to png_jmpbuf().
+  Fixed "interlace" typo (should be "interlaced") in contrib/gregbook/read2-x.c
+  Fixed bug with use of PNG_BEFORE_IHDR bit in png_ptr->mode, introduced when
+    PNG_FLAG_HAVE_CHUNK_HEADER was moved into png_ptr->mode in version 1.0.5b
+  Files in contrib/gregbook were revised to use png_jmpbuf() and to select
+    a 24-bit visual if one is available, and to allow abbreviated options.
+  Files in contrib/pngminus were revised to use the png_jmpbuf() macro.
+  Removed spaces in makefile.linux and makefile.gcmmx, introduced in 1.0.5s
+version 1.0.5u [March 5, 2000]
+  Simplified the code that detects old png.h in png.c and pngtest.c
+  Renamed png_spalette (_p, _pp) to png_sPLT_t (_tp, _tpp)
+  Increased precision of rgb_to_gray calculations from 8 to 15 bits and
+    added png_set_rgb_to_gray_fixed() function.
+  Added makefile.bc32 (32-bit Borland C++, C mode)
+version 1.0.5v [March 11, 2000]
+  Added some parentheses to the png_jmpbuf macro definition.
+  Updated references to the zlib home page, which has moved to freesoftware.com.
+  Corrected bugs in documentation regarding png_read_row() and png_write_row().
+  Updated documentation of png_rgb_to_gray calculations in libpng.3/libpng.txt.
+  Renamed makefile.borland,turboc3 back to makefile.bor,tc3 as in version 1.0.3,
+    revised borland makefiles; added makefile.ibmvac3 and makefile.gcc (Cosmin)
+
+version 1.0.6 [March 20, 2000]
+  Minor revisions of makefile.bor, libpng.txt, and gregbook/rpng2-win.c
+  Added makefile.sggcc (SGI IRIX with gcc)
+version 1.0.6d [April 7, 2000]
+  Changed sprintf() to strcpy() in png_write_sCAL_s() to work without STDIO
+  Added data_length parameter to png_decompress_chunk() function
+  Revised documentation to remove reference to abandoned png_free_chnk functions
+  Fixed an error in png_rgb_to_gray_fixed()
+  Revised example.c, usage of png_destroy_write_struct().
+  Renamed makefile.ibmvac3 to makefile.ibmc, added libpng.icc IBM project file
+  Added a check for info_ptr->free_me&PNG_FREE_TEXT when freeing text in png.c
+  Simplify png_sig_bytes() function to remove use of non-ISO-C strdup().
+version 1.0.6e [April 9, 2000]
+  Added png_data_freer() function.
+  In the code that checks for over-length tRNS chunks, added check of
+    info_ptr->num_trans as well as png_ptr->num_trans (Matthias Benckmann)
+  Minor revisions of libpng.txt/libpng.3.
+  Check for existing data and free it if the free_me flag is set, in png_set_*()
+    and png_handle_*().
+  Only define PNG_WEIGHTED_FILTERS_SUPPORTED when PNG_FLOATING_POINT_SUPPORTED
+    is defined.
+  Changed several instances of PNG_NO_CONSOLE_ID to PNG_NO_STDIO in pngrutil.c
+    and mentioned the purposes of the two macros in libpng.txt/libpng.3.
+version 1.0.6f [April 14, 2000]
+  Revised png_set_iCCP() and png_set_rows() to avoid prematurely freeing data.
+  Add checks in png_set_text() for NULL members of the input text structure.
+  Revised libpng.txt/libpng.3.
+  Removed superfluous prototype for png_set_itxt from png.h
+  Removed "else" from pngread.c, after png_error(), and changed "0" to "length".
+  Changed several png_errors about malformed ancillary chunks to png_warnings.
+version 1.0.6g [April 24, 2000]
+  Added png_pass-* arrays to pnggccrd.c when PNG_USE_LOCAL_ARRAYS is defined.
+  Relocated paragraph about png_set_background() in libpng.3/libpng.txt
+    and other revisions (Matthias Benckmann)
+  Relocated info_ptr->free_me, png_ptr->free_me, and other info_ptr and
+    png_ptr members to restore binary compatibility with libpng-1.0.5
+    (breaks compatibility with libpng-1.0.6).
+version 1.0.6h [April 24, 2000]
+  Changed shared library so-number pattern from 2.x.y.z to xy.z (this builds
+    libpng.so.10 & libpng.so.10.6h instead of libpng.so.2 & libpng.so.2.1.0.6h)
+    This is a temporary change for test purposes.
+version 1.0.6i [May 2, 2000]
+  Rearranged some members at the end of png_info and png_struct, to put
+    unknown_chunks_num and free_me within the original size of the png_structs
+    and free_me, png_read_user_fn, and png_free_fn within the original png_info,
+    because some old applications allocate the structs directly instead of
+    using png_create_*().
+  Added documentation of user memory functions in libpng.txt/libpng.3
+  Modified png_read_png so that it will use user_allocated row_pointers
+    if present, unless free_me directs that it be freed, and added description
+    of the use of png_set_rows() and png_get_rows() in libpng.txt/libpng.3.
+  Added PNG_LEGACY_SUPPORTED macro, and #ifdef out all new (since version
+    1.00) members of png_struct and png_info, to regain binary compatibility
+    when you define this macro.  Capabilities lost in this event
+    are user transforms (new in version 1.0.0),the user transform pointer
+    (new in version 1.0.2), rgb_to_gray (new in 1.0.5), iCCP, sCAL, sPLT,
+    the high-level interface, and unknown chunks support (all new in 1.0.6).
+    This was necessary because of old applications that allocate the structs
+    directly as authors were instructed to do in libpng-0.88 and earlier,
+    instead of using png_create_*().
+  Added modes PNG_CREATED_READ_STRUCT and PNG_CREATED_WRITE_STRUCT which
+    can be used to detect codes that directly allocate the structs, and
+    code to check these modes in png_read_init() and png_write_init() and
+    generate a libpng error if the modes aren't set and PNG_LEGACY_SUPPORTED
+    was not defined.
+  Added makefile.intel and updated makefile.watcom (Pawel Mrochen)
+version 1.0.6j [May 3, 2000]
+  Overloaded png_read_init() and png_write_init() with macros that convert
+    calls to png_read_init_2() or png_write_init_2() that check the version
+    and structure sizes.
+version 1.0.7beta11 [May 7, 2000]
+  Removed the new PNG_CREATED_READ_STRUCT and PNG_CREATED_WRITE_STRUCT modes
+    which are no longer used.
+  Eliminated the three new members of png_text when PNG_LEGACY_SUPPORTED is
+    defined or when neither PNG_READ_iTXt_SUPPORTED nor PNG_WRITE_iTXT_SUPPORTED
+    is defined.
+  Made PNG_NO_READ|WRITE_iTXt the default setting, to avoid memory
+    overrun when old applications fill the info_ptr->text structure directly.
+  Added PNGAPI macro, and added it to the definitions of all exported functions.
+  Relocated version macro definitions ahead of the includes of zlib.h and
+    pngconf.h in png.h.
+version 1.0.7beta12 [May 12, 2000]
+  Revised pngset.c to avoid a problem with expanding the png_debug macro.
+  Deleted some extraneous defines from pngconf.h
+  Made PNG_NO_CONSOLE_IO the default condition when PNG_BUILD_DLL is defined.
+  Use MSC _RPTn debugging instead of fprintf if _MSC_VER is defined.
+  Added png_access_version_number() function.
+  Check for mask&PNG_FREE_CHNK (for TEXT, SCAL, PCAL) in png_free_data().
+  Expanded libpng.3/libpng.txt information about png_data_freer().
+version 1.0.7beta14 [May 17, 2000] (beta13 was not published)
+  Changed pnggccrd.c and pngvcrd.c to handle bad adaptive filter types as
+    warnings instead of errors, as pngrutil.c does.
+  Set the PNG_INFO_IDAT valid flag in png_set_rows() so png_write_png()
+    will actually write IDATs.
+  Made the default PNG_USE_LOCAL_ARRAYS depend on PNG_DLL instead of WIN32.
+  Make png_free_data() ignore its final parameter except when freeing data
+    that can have multiple instances (text, sPLT, unknowns).
+  Fixed a new bug in png_set_rows().
+  Removed info_ptr->valid tests from png_free_data(), as in version 1.0.5.
+  Added png_set_invalid() function.
+  Fixed incorrect illustrations of png_destroy_write_struct() in example.c.
+version 1.0.7beta15 [May 30, 2000]
+  Revised the deliberately erroneous Linux setjmp code in pngconf.h to produce
+    fewer error messages.
+  Rearranged checks for Z_OK to check the most likely path first in pngpread.c
+    and pngwutil.c.
+  Added checks in pngtest.c for png_create_*() returning NULL, and mentioned
+    in libpng.txt/libpng.3 the need for applications to check this.
+  Changed names of png_default_*() functions in pngtest to pngtest_*().
+  Changed return type of png_get_x|y_offset_*() from png_uint_32 to png_int_32.
+  Fixed some bugs in the unused PNG_INCH_CONVERSIONS functions in pngget.c
+  Set each pointer to NULL after freeing it in png_free_data().
+  Worked around a problem in pngconf.h; AIX's strings.h defines an "index"
+    macro that conflicts with libpng's png_color_16.index. (Dimitri Papadapoulos)
+  Added "msvc" directory with MSVC++ project files (Simon-Pierre Cadieux).
+version 1.0.7beta16 [June 4, 2000]
+  Revised the workaround of AIX string.h "index" bug.
+  Added a check for overlength PLTE chunk in pngrutil.c.
+  Added PNG_NO_POINTER_INDEXING macro to use array-indexing instead of pointer
+    indexing in pngrutil.c and pngwutil.c to accommodate a buggy compiler.
+  Added a warning in png_decompress_chunk() when it runs out of data, e.g.
+    when it tries to read an erroneous PhotoShop iCCP chunk.
+  Added PNG_USE_DLL macro.
+  Revised the copyright/disclaimer/license notice.
+  Added contrib/msvctest directory
+version 1.0.7rc1 [June 9, 2000]
+  Corrected the definition of PNG_TRANSFORM_INVERT_ALPHA  (0x0400 not 0x0200)
+  Added contrib/visupng directory (Willem van Schaik)
+version 1.0.7beta18 [June 23, 2000]
+  Revised PNGAPI definition, and pngvcrd.c to work with __GCC__
+    and do not redefine PNGAPI if it is passed in via a compiler directive.
+  Revised visupng/PngFile.c to remove returns from within the Try block.
+  Removed leading underscores from "_PNG_H" and "_PNG_SAVE_BSD_SOURCE" macros.
+  Updated contrib/visupng/cexcept.h to version 1.0.0.
+  Fixed bugs in pngwrite.c and pngwutil.c that prevented writing iCCP chunks.
+version 1.0.7rc2 [June 28, 2000]
+  Updated license to include disclaimers required by UCITA.
+  Fixed "DJBPP" typo in pnggccrd.c introduced in beta18.
+
+version 1.0.7 [July 1, 2000]
+  Revised the definition of "trans_values" in libpng.3/libpng.txt
+version 1.0.8beta1 [July 8, 2000]
+  Added png_free(png_ptr, key) two places in pngpread.c to stop memory leaks.
+  Changed PNG_NO_STDIO to PNG_NO_CONSOLE_IO, several places in pngrutil.c and
+     pngwutil.c.
+  Changed PNG_EXPORT_VAR to use PNG_IMPEXP, in pngconf.h.
+  Removed unused "#include <assert.h>" from png.c
+  Added WindowsCE support.
+  Revised pnggccrd.c to work with gcc-2.95.2 and in the Cygwin environment.
+version 1.0.8beta2 [July 10, 2000]
+  Added project files to the wince directory and made further revisions
+     of pngtest.c, pngrio.c, and pngwio.c in support of WindowsCE.
+version 1.0.8beta3 [July 11, 2000]
+  Only set the PNG_FLAG_FREE_TRNS or PNG_FREE_TRNS flag in png_handle_tRNS()
+     for indexed-color input files to avoid potential double-freeing trans array
+     under some unusual conditions; problem was introduced in version 1.0.6f.
+  Further revisions to pngtest.c and files in the wince subdirectory.

+
+version 1.2.36beta05 [April 24, 2009]

+  No changes.
+
+version 1.0.44 and 1.2.36 [May 7, 2009]
+  No changes.
+
+version 1.2.37beta01 [May 14, 2009]
+  Fixed inconsistency in pngrutil.c, introduced in libpng-1.2.36.  The

+  Updated some of the makefiles in the scripts directory (merged with
+    those in libpng-1.4.0beta57).

+version 1.2.37beta03 [May 20, 2009]
+  In contrib/pngminim/*, renamed "makefile.std" to "makefile", since there
+    is only one makefile in those directories, and revised the README files
+    accordingly.
+  Reformated sources in libpng style (3-space indentation, comment format)
+
+version 1.2.37rc01 [May 27, 2009]
+  No changes.

+version 1.2.38beta01 [June 17, 2009]
+  Revised libpng*.txt and libpng.3 to mention calling png_set_IHDR()
+    multiple times and to specify the sample order in the tRNS chunk,
+    because the ISO PNG specification has a typo in the tRNS table.
+  Changed several PNG_UNKNOWN_CHUNK_SUPPORTED to
+    PNG_HANDLE_AS_UNKNOWN_SUPPORTED, to make the png_set_keep mechanism
+    available for ignoring known chunks even when not saving unknown chunks.
+  Adopted preference for consistent use of "#ifdef" and "#ifndef" versus
+    "#if defined()" and "if !defined()" where possible.
+  Added PNG_NO_HANDLE_AS_UNKNOWN in the PNG_LEGACY_SUPPORTED block of
+    pngconf.h, and moved the various unknown chunk macro definitions
+    outside of the PNG_READ|WRITE_ANCILLARY_CHUNK_SUPPORTED blocks.
+

+  No changes.
+
+version 1.2.40beta01 [August 20, 2009]

+  Revised png_check_IHDR() again, to check info_ptr members instead of
+    the contents of the returned parameters.
+
+version 1.2.41beta04 [October 7, 2009]
+  Added "xcode" project similar one already in libpng-1.4.0beta (Alam Arias).
+  Ported some cosmetic changes from libpng-1.4.0beta86.
+  Eliminated a shadowed declaration of "pp" in png_handle_sPLT().
+
+version 1.2.41beta05 [October 17, 2009]
+  Revised pngconf.h to make it easier to enable iTXt support.  From libpng
+    version 1.2.9 through 1.2.40, defining PNG_iTXt_SUPPORTED did not work
+    as expected.
+  Ported some cosmetic changes from libpng-1.4.0beta87, changing
+    many "#if defined(x)" to "#ifdef x".

+    png_get_io_state(), png_set_user_cache_max(), png_get_user_cache_max(),
+    png_set_premultiply_alpha, and png_do_read_premultiply_alpha().
+  Relocated png_do_chop() ahead of building gamma tables in pngrtran.c
+    This avoids building 16-bit gamma tables unnecessarily.

+
+version 1.2.41beta10 [November 1, 2009]
+  Enabled iTXt support by default. To ensure binary compatibility with
+    previous versions, the "lang" and "lang_key" members will be assumed
+    to be omitted from previous versions unless the current libpng
+    version was built with PNG_iTXt_SUPPORTED (which is otherwise no
+    longer necessary to gain iTXt support), as a signal that the user has
+    been building previous versions with PNG_iTXt_SUPPORTED as well.
+
+version 1.2.41beta11 [November 2, 2009]
+  Store user's user_png_ver in new png_ptr->user_png_ver element.
+  Revised iTXt support. To ensure binary compatibility with
+    previous versions, the "lang" and "lang_key" members will be assumed
+    to be omitted from versions prior to 1.2.41beta11 whenever there is a
+    library mismatch.
+
+version 1.2.41beta12 [November 2, 2009]
+  Free png_ptr->user_png_ver when destroying png_ptr.
+

+  Updated scripts/pngw32.def and projects/wince/png32ce.def
+  Copied projects/wince/png32ce.def to the scripts directory.
+  Added scripts/makefile.wce
+  Patched ltmain.sh for wince support.
+  Added PNG_CONVERT_tIME_SUPPORTED macro.
+
+version 1.2.41beta14 [November 8, 2009]
+  versions 1.2.41beta05 through 1.2.41beta13 were abandoned.
+  The 1.0.x/1.2.x series will only receive security updates from now on.
+  Make inclusion of time.h in pngconf.h depend on PNG_CONVERT_tIME_SUPPORTED
+  Make #define PNG_CONVERT_tIME_SUPPORTED depend on PNG_WRITE_tIME_SUPPORTED
+  Reverted iTXt compatibility stuff from 1.2.41beta05, 1.2.41beta11, and
+    1.2.41beta12.
+  Reverted IOSTATE feature, user_cache_max, and premultiply_alpha features
+    from 1.2.41beta08.
+  Retained png_calloc() from 1.2.41beta08 but as a non-exported function,
+    and removed reference to png_calloc from scripts/*.def
+
+version 1.2.41beta15 [November 8, 2009]
+  Added PNG_DEPSTRUCT, PNG_DEPRECATED, PNG_USE_RESULT, PNG_NORETURN, and
+    PNG_ALLOCATED macros to detect deprecated direct access to the
+    png_struct or info_struct members and other deprecated usage in
+    applications (John Bowler).
+  Updated scripts/makefile* to add "-DPNG_CONFIGURE_LIBPNG" to CFLAGS,
+    to prevent warnings about direct access to png structs by libpng
+    functions while building libpng.  They need to be tested, especially
+    those using compilers other than gcc.
+  Updated projects/visualc6 and visualc71 with "/d PNG_CONFIGURE_LIBPNG".
+
+version 1.2.41beta16 [November 9, 2009]
+  Removed three direct references to read_info_ptr members in pngtest.c
+    that were detected by the new PNG_DEPSTRUCT macro.
+  Only #define PNG_DEPSTRUCT, etc. in pngconf.h if not already defined.
+
+version 1.2.41beta17 [November 10, 2009]
+  Updated CMakeLists.txt to add "-DPNG_CONFIGURE_LIBPNG" to the definitions.
+  Marked deprecated function prototypes with PNG_DEPRECATED.
+  Marked memory allocation function prototypes with PNG_ALLOCATED.
+  Changed png_check_sig() to !png_sig_cmp() in contrib programs.
+  Corrected the png_get_IHDR() call in contrib/gregbook/readpng2.c
+  Added "-DPNG_CONFIGURE_LIBPNG" to the contrib/pngminum makefiles.
+
+version 1.2.41beta18 [November 11, 2009]
+  Renamed scripts/makefile.wce to scripts/makefile.cegcc
+  Marked nonexported functions with PNG_PRIVATE macro.
+

+version 1.2.42beta01 [December 4, 2009]
+  Removed "#define PNG_NO_ERROR_NUMBERS" that was inadvertently added
+    to pngconf.h in version 1.2.41.
+  Revised scripts/makefile.netbsd, makefile.openbsd, and makefile.sco
+    to put png.h and pngconf.h in $prefix/include, like the other scripts,

+
+Known bugs in libpng version 1.2.44
+
+1. December 4, 2009: The PNG_NO_ERROR_NUMBERS macro was inadvertently
+   defined in libpng-1.2.41/pngconf.h, which may cause a problem with
+   building a binary-compatible library.
+
+   STATUS: This will be fixed in libpng-1.2.42.  In the meantime, simply
+   delete the definition from line :
+
+2. February 23, 2006: The custom makefiles don't build libpng with -lz.
+
+   STATUS: This is a subject of debate. The change will probably be made
+   as a part of a major overhaul of the makefiles in libpng version 1.4.0.
+
+3. February 24, 2006: The Makefile generated by the "configure" script
+   fails to install symbolic links
+   libpng12.so => libpng12.so.0.1.2.9betaN
+   that are generated by the custom makefiles.
+
+4. September 4, 2007:  There is a report that pngtest crashes on MacOS 10.
+
+   STATUS: workarounds are
+      1) Compile without optimization (crashes are observed with
+         -arch i386 and -O2 or -O3, using gcc-4.0.1).
+      2) Compile pngtest.c with PNG_DEBUG defined (the bug goes away if
+         you try to look at it).
+      3) Ignore the crash.  The library itself seems to be OK.

+README for libpng version 1.2.44 - June 26, 2010 (shared library 12.0)
+See the note about version numbers near the top of png.h
+
+See INSTALL for instructions on how to install libpng.
+
+Libpng comes in several distribution formats.  Get libpng-*.tar.gz,
+libpng-*.tar.xz, or libpng-*.tar.bz2 if you want UNIX-style line
+endings in the text files, or lpng*.7z or lpng*.zip if you want DOS-style
+line endings.  You can get UNIX-style line endings from the *.zip file
+by using "unzip -a" but there seems to be no simple way to recover
+UNIX-style line endings from the *.7z file.  The *.tar.xz file is
+recommended for *NIX users instead.
+
+Version 0.89 was the first official release of libpng.  Don't let the
+fact that it's the first release fool you.  The libpng library has been in
+extensive use and testing since mid-1995.  By late 1997 it had
+finally gotten to the stage where there hadn't been significant
+changes to the API in some time, and people have a bad feeling about
+libraries with versions < 1.0.  Version 1.0.0 was released in
+March 1998.
+
+****
+Note that some of the changes to the png_info structure render this
+version of the library binary incompatible with libpng-0.89 or
+earlier versions if you are using a shared library.  The type of the
+"filler" parameter for png_set_filler() has changed from png_byte to
+png_uint_32, which will affect shared-library applications that use
+this function.
+
+To avoid problems with changes to the internals of png_info_struct,
+new APIs have been made available in 0.95 to avoid direct application
+access to info_ptr.  These functions are the png_set_<chunk> and
+png_get_<chunk> functions.  These functions should be used when
+accessing/storing the info_struct data, rather than manipulating it
+directly, to avoid such problems in the future.
+
+It is important to note that the APIs do not make current programs
+that access the info struct directly incompatible with the new
+library.  However, it is strongly suggested that new programs use
+the new APIs (as shown in example.c and pngtest.c), and older programs
+be converted to the new format, to facilitate upgrades in the future.
+****
+
+Additions since 0.90 include the ability to compile libpng as a
+Windows DLL, and new APIs for accessing data in the info struct.
+Experimental functions include the ability to set weighting and cost
+factors for row filter selection, direct reads of integers from buffers
+on big-endian processors that support misaligned data access, faster
+methods of doing alpha composition, and more accurate 16->8 bit color
+conversion.
+
+The additions since 0.89 include the ability to read from a PNG stream
+which has had some (or all) of the signature bytes read by the calling
+application.  This also allows the reading of embedded PNG streams that
+do not have the PNG file signature.  As well, it is now possible to set
+the library action on the detection of chunk CRC errors.  It is possible
+to set different actions based on whether the CRC error occurred in a
+critical or an ancillary chunk.
+
+The changes made to the library, and bugs fixed are based on discussions
+on the png-mng-implement mailing list and not on material submitted
+privately to Guy, Andreas, or Glenn.  They will forward any good
+suggestions to the list.
+
+For a detailed description on using libpng, read libpng.txt.  For
+examples of libpng in a program, see example.c and pngtest.c.  For usage
+information and restrictions (what little they are) on libpng, see
+png.h.  For a description on using zlib (the compression library used by
+libpng) and zlib's restrictions, see zlib.h
+
+I have included a general makefile, as well as several machine and
+compiler specific ones, but you may have to modify one for your own needs.
+
+You should use zlib 1.0.4 or later to run this, but it MAY work with
+versions as old as zlib 0.95.  Even so, there are bugs in older zlib
+versions which can cause the output of invalid compression streams for
+some images.  You will definitely need zlib 1.0.4 or later if you are
+taking advantage of the MS-DOS "far" structure allocation for the small
+and medium memory models.  You should also note that zlib is a
+compression library that is useful for more things than just PNG files.
+You can use zlib as a drop-in replacement for fread() and fwrite() if
+you are so inclined.
+
+zlib should be available at the same place that libpng is, or at
+ftp://ftp.simplesystems.org/pub/png/src/
+
+You may also want a copy of the PNG specification.  It is available
+as an RFC, a W3C Recommendation, and an ISO/IEC Standard.  You can find
+these at http://www.libpng.org/pub/png/pngdocs.html
+
+This code is currently being archived at libpng.sf.net in the
+[DOWNLOAD] area, and on CompuServe, Lib 20 (PNG SUPPORT)
+at GO GRAPHSUP.  If you can't find it in any of those places,
+e-mail me, and I'll help you find it.
+
+If you have any code changes, requests, problems, etc., please e-mail
+them to me.  Also, I'd appreciate any make files or project files,
+and any modifications you needed to make to get libpng to compile,
+along with a #define variable to tell what compiler/system you are on.
+If you needed to add transformations to libpng, or wish libpng would
+provide the image in a different way, drop me a note (and code, if
+possible), so I can consider supporting the transformation.
+Finally, if you get any warning messages when compiling libpng
+(note: not zlib), and they are easy to fix, I'd appreciate the
+fix.  Please mention "libpng" somewhere in the subject line.  Thanks.
+
+This release was created and will be supported by myself (of course
+based in a large way on Guy's and Andreas' earlier work), and the PNG
+development group.

+TODO - list of things to do for libpng:
+
+Final bug fixes.
+Improve API by hiding the png_struct and png_info structs.
+Finish work on the no-floating-point version (including gamma compensation)
+Better C++ wrapper/full C++ implementation?
+Fix problem with C++ and EXTERN "C".
+cHRM transformation.
+Improve setjmp/longjmp usage or remove it in favor of returning error codes.
+Add "grayscale->palette" transformation and "palette->grayscale" detection.
+Improved dithering.
+Multi-lingual error and warning message support.
+Complete sRGB transformation (presently it simply uses gamma=0.45455).
+Man pages for function calls.
+Better documentation.
+Better filter selection
+   (counting huffman bits/precompression?  filter inertia?  filter costs?).
+Histogram creation.
+Text conversion between different code pages (Latin-1 -> Mac and DOS).
+Should we always malloc 2^bit_depth PLTE/tRNS/hIST entries for safety?
+Build gamma tables using fixed point (and do away with floating point entirely).
+Use greater precision when changing to linear gamma for compositing against
+  background and doing rgb-to-gray transformation.
+Investigate pre-incremented loop counters and other loop constructions.
+Add interpolated method of handling interlacing.

+   Y2K compliance in libpng:
+   =========================
+
+      June 26, 2010
+
+      Since the PNG Development group is an ad-hoc body, we can't make
+      an official declaration.
+
+      This is your unofficial assurance that libpng from version 0.71 and
+      upward through 1.2.44 are Y2K compliant.  It is my belief that earlier
+      versions were also Y2K compliant.
+
+      Libpng only has three year fields.  One is a 2-byte unsigned integer
+      that will hold years up to 65535.  The other two hold the date in text
+      format, and will hold years up to 9999.
+
+      The integer is
+          "png_uint_16 year" in png_time_struct.
+
+      The strings are
+          "png_charp time_buffer" in png_struct and
+          "near_time_buffer", which is a local character string in png.c.
+
+      There are seven time-related functions:
+
+          png_convert_to_rfc_1123() in png.c
+            (formerly png_convert_to_rfc_1152() in error)
+          png_convert_from_struct_tm() in pngwrite.c, called in pngwrite.c
+          png_convert_from_time_t() in pngwrite.c
+          png_get_tIME() in pngget.c
+          png_handle_tIME() in pngrutil.c, called in pngread.c
+          png_set_tIME() in pngset.c
+          png_write_tIME() in pngwutil.c, called in pngwrite.c
+
+      All appear to handle dates properly in a Y2K environment.  The
+      png_convert_from_time_t() function calls gmtime() to convert from system
+      clock time, which returns (year - 1900), which we properly convert to
+      the full 4-digit year.  There is a possibility that applications using
+      libpng are not passing 4-digit years into the png_convert_to_rfc_1123()
+      function, or that they are incorrectly passing only a 2-digit year
+      instead of "year - 1900" into the png_convert_from_struct_tm() function,
+      but this is not under our control.  The libpng documentation has always
+      stated that it works with 4-digit years, and the APIs have been
+      documented as such.
+
+      The tIME chunk itself is also Y2K compliant.  It uses a 2-byte unsigned
+      integer to hold the year, and can hold years as large as 65535.
+
+      zlib, upon which libpng depends, is also Y2K compliant.  It contains
+      no date-related code.

+.SH I. Introduction
+
+This file describes how to use and modify the PNG reference library
+(known as libpng) for your own use.  There are five sections to this
+file: introduction, structures, reading, writing, and modification and
+configuration notes for various special platforms.  In addition to this
+file, example.c is a good starting point for using the library, as
+it is heavily commented and should include everything most people
+will need.  We assume that libpng is already installed; see the
+INSTALL file for instructions on how to install libpng.
+
+For examples of libpng usage, see the files "example.c", "pngtest.c",
+and the files in the "contrib" directory, all of which are included in
+the libpng distribution.
+
+Libpng was written as a companion to the PNG specification, as a way
+of reducing the amount of time and effort it takes to support the PNG
+file format in application programs.
+
+The PNG specification (second edition), November 2003, is available as
+a W3C Recommendation and as an ISO Standard (ISO/IEC 15948:2003 (E)) at
+<http://www.w3.org/TR/2003/REC-PNG-20031110/
+The W3C and ISO documents have identical technical content.
+
+The PNG-1.2 specification is available at
+<http://www.libpng.org/pub/png/documents/>.  It is technically equivalent
+to the PNG specification (second edition) but has some additional material.
+
+The PNG-1.0 specification is available
+as RFC 2083 <http://www.libpng.org/pub/png/documents/> and as a
+W3C Recommendation <http://www.w3.org/TR/REC.png.html>.
+
+Some additional chunks are described in the special-purpose public chunks
+documents at <http://www.libpng.org/pub/png/documents/>.
+
+Other information
+about PNG, and the latest version of libpng, can be found at the PNG home
+page, <http://www.libpng.org/pub/png/>.
+
+Most users will not have to modify the library significantly; advanced
+users may want to modify it more.  All attempts were made to make it as
+complete as possible, while keeping the code easy to understand.
+Currently, this library only supports C.  Support for other languages
+is being considered.
+
+Libpng has been designed to handle multiple sessions at one time,
+to be easily modifiable, to be portable to the vast majority of
+machines (ANSI, K&R, 16-, 32-, and 64-bit) available, and to be easy
+to use.  The ultimate goal of libpng is to promote the acceptance of
+the PNG file format in whatever way possible.  While there is still
+work to be done (see the TODO file), libpng should cover the
+majority of the needs of its users.
+
+Libpng uses zlib for its compression and decompression of PNG files.
+Further information about zlib, and the latest version of zlib, can
+be found at the zlib home page, <http://www.info-zip.org/pub/infozip/zlib/>.
+The zlib compression utility is a general purpose utility that is
+useful for more than PNG files, and can be used without libpng.
+See the documentation delivered with zlib for more details.
+You can usually find the source files for the zlib utility wherever you
+find the libpng source files.
+
+Libpng is thread safe, provided the threads are using different
+instances of the structures.  Each thread should have its own
+png_struct and png_info instances, and thus its own image.
+Libpng does not protect itself against two threads using the
+same instance of a structure.
+
+.SH II. Structures
+
+There are two main structures that are important to libpng, png_struct
+and png_info.  The first, png_struct, is an internal structure that
+will not, for the most part, be used by a user except as the first
+variable passed to every libpng function call.
+
+The png_info structure is designed to provide information about the
+PNG file.  At one time, the fields of png_info were intended to be
+directly accessible to the user.  However, this tended to cause problems
+with applications using dynamically loaded libraries, and as a result
+a set of interface functions for png_info (the png_get_*() and png_set_*()
+functions) was developed.  The fields of png_info are still available for
+older applications, but it is suggested that applications use the new
+interfaces if at all possible.
+
+Applications that do make direct access to the members of png_struct (except
+for png_ptr->jmpbuf) must be recompiled whenever the library is updated,
+and applications that make direct access to the members of png_info must
+be recompiled if they were compiled or loaded with libpng version 1.0.6,
+in which the members were in a different order.  In version 1.0.7, the
+members of the png_info structure reverted to the old order, as they were
+in versions 0.97c through 1.0.5.  Starting with version 2.0.0, both
+structures are going to be hidden, and the contents of the structures will
+only be accessible through the png_get/png_set functions.
+
+The png.h header file is an invaluable reference for programming with libpng.
+And while I'm on the topic, make sure you include the libpng header file:
+
+#include <png.h>
+
+.SH III. Reading
+
+We'll now walk you through the possible functions to call when reading
+in a PNG file sequentially, briefly explaining the syntax and purpose
+of each one.  See example.c and png.h for more detail.  While
+progressive reading is covered in the next section, you will still
+need some of the functions discussed in this section to read a PNG
+file.
+
+.SS Setup
+
+You will want to do the I/O initialization(*) before you get into libpng,
+so if it doesn't work, you don't have much to undo.  Of course, you
+will also want to insure that you are, in fact, dealing with a PNG
+file.  Libpng provides a simple check to see if a file is a PNG file.
+To use it, pass in the first 1 to 8 bytes of the file to the function
+png_sig_cmp(), and it will return 0 (false) if the bytes match the
+corresponding bytes of the PNG signature, or nonzero (true) otherwise.
+Of course, the more bytes you pass in, the greater the accuracy of the
+prediction.
+
+If you are intending to keep the file pointer open for use in libpng,
+you must ensure you don't read more than 8 bytes from the beginning
+of the file, and you also have to make a call to png_set_sig_bytes_read()
+with the number of bytes you read from the beginning.  Libpng will
+then only check the bytes (if any) that your program didn't read.
+
+(*): If you are not using the standard I/O functions, you will need
+to replace them with custom functions.  See the discussion under
+Customizing libpng.
+
+
+    FILE *fp = fopen(file_name, "rb");
+    if (!fp)
+    {
+        return (ERROR);
+    }
+    fread(header, 1, number, fp);
+    is_png = !png_sig_cmp(header, 0, number);
+    if (!is_png)
+    {
+        return (NOT_PNG);
+    }
+
+
+Next, png_struct and png_info need to be allocated and initialized.  In
+order to ensure that the size of these structures is correct even with a
+dynamically linked libpng, there are functions to initialize and
+allocate the structures.  We also pass the library version, optional
+pointers to error handling functions, and a pointer to a data struct for
+use by the error functions, if necessary (the pointer and functions can
+be NULL if the default error handlers are to be used).  See the section
+on Changes to Libpng below regarding the old initialization functions.
+The structure allocation functions quietly return NULL if they fail to
+create the structure, so your application should check for that.
+
+    png_structp png_ptr = png_create_read_struct
+       (PNG_LIBPNG_VER_STRING, (png_voidp)user_error_ptr,
+        user_error_fn, user_warning_fn);
+    if (!png_ptr)
+        return (ERROR);
+
+    png_infop info_ptr = png_create_info_struct(png_ptr);
+    if (!info_ptr)
+    {
+        png_destroy_read_struct(&png_ptr,
+           (png_infopp)NULL, (png_infopp)NULL);
+        return (ERROR);
+    }
+
+    png_infop end_info = png_create_info_struct(png_ptr);
+    if (!end_info)
+    {
+        png_destroy_read_struct(&png_ptr, &info_ptr,
+          (png_infopp)NULL);
+        return (ERROR);
+    }
+
+If you want to use your own memory allocation routines,
+define PNG_USER_MEM_SUPPORTED and use
+png_create_read_struct_2() instead of png_create_read_struct():
+
+    png_structp png_ptr = png_create_read_struct_2
+       (PNG_LIBPNG_VER_STRING, (png_voidp)user_error_ptr,
+        user_error_fn, user_warning_fn, (png_voidp)
+        user_mem_ptr, user_malloc_fn, user_free_fn);
+
+The error handling routines passed to png_create_read_struct()
+and the memory alloc/free routines passed to png_create_struct_2()
+are only necessary if you are not using the libpng supplied error
+handling and memory alloc/free functions.
+
+When libpng encounters an error, it expects to longjmp back
+to your routine.  Therefore, you will need to call setjmp and pass
+your png_jmpbuf(png_ptr).  If you read the file from different
+routines, you will need to update the jmpbuf field every time you enter
+a new routine that will call a png_*() function.
+
+See your documentation of setjmp/longjmp for your compiler for more
+information on setjmp/longjmp.  See the discussion on libpng error
+handling in the Customizing Libpng section below for more information
+on the libpng error handling.  If an error occurs, and libpng longjmp's
+back to your setjmp, you will want to call png_destroy_read_struct() to
+free any memory.
+
+    if (setjmp(png_jmpbuf(png_ptr)))
+    {
+        png_destroy_read_struct(&png_ptr, &info_ptr,
+           &end_info);
+        fclose(fp);
+        return (ERROR);
+    }
+
+If you would rather avoid the complexity of setjmp/longjmp issues,
+you can compile libpng with PNG_SETJMP_NOT_SUPPORTED, in which case
+errors will result in a call to PNG_ABORT() which defaults to abort().
+
+Now you need to set up the input code.  The default for libpng is to
+use the C function fread().  If you use this, you will need to pass a
+valid FILE * in the function png_init_io().  Be sure that the file is
+opened in binary mode.  If you wish to handle reading data in another
+way, you need not call the png_init_io() function, but you must then
+implement the libpng I/O methods discussed in the Customizing Libpng
+section below.
+
+    png_init_io(png_ptr, fp);
+
+If you had previously opened the file and read any of the signature from
+the beginning in order to see if this was a PNG file, you need to let
+libpng know that there are some bytes missing from the start of the file.
+
+    png_set_sig_bytes(png_ptr, number);
+
+.SS Setting up callback code
+
+You can set up a callback function to handle any unknown chunks in the
+input stream. You must supply the function
+
+    read_chunk_callback(png_ptr ptr,
+         png_unknown_chunkp chunk);
+    {
+       /* The unknown chunk structure contains your
+          chunk data, along with similar data for any other
+          unknown chunks: */
+
+           png_byte name[5];
+           png_byte *data;
+           png_size_t size;
+
+       /* Note that libpng has already taken care of
+          the CRC handling */
+
+       /* put your code here.  Search for your chunk in the
+          unknown chunk structure, process it, and return one
+          of the following: */
+
+       return (-n); /* chunk had an error */
+       return (0); /* did not recognize */
+       return (n); /* success */
+    }
+
+(You can give your function another name that you like instead of
+"read_chunk_callback")
+
+To inform libpng about your function, use
+
+    png_set_read_user_chunk_fn(png_ptr, user_chunk_ptr,
+        read_chunk_callback);
+
+This names not only the callback function, but also a user pointer that
+you can retrieve with
+
+    png_get_user_chunk_ptr(png_ptr);
+
+If you call the png_set_read_user_chunk_fn() function, then all unknown
+chunks will be saved when read, in case your callback function will need
+one or more of them.  This behavior can be changed with the
+png_set_keep_unknown_chunks() function, described below.
+
+At this point, you can set up a callback function that will be
+called after each row has been read, which you can use to control
+a progress meter or the like.  It's demonstrated in pngtest.c.
+You must supply a function
+
+    void read_row_callback(png_ptr ptr, png_uint_32 row,
+       int pass);
+    {
+      /* put your code here */
+    }
+
+(You can give it another name that you like instead of "read_row_callback")
+
+To inform libpng about your function, use
+
+    png_set_read_status_fn(png_ptr, read_row_callback);
+
+.SS Unknown-chunk handling
+
+Now you get to set the way the library processes unknown chunks in the
+input PNG stream. Both known and unknown chunks will be read.  Normal
+behavior is that known chunks will be parsed into information in
+various info_ptr members while unknown chunks will be discarded. This
+behavior can be wasteful if your application will never use some known
+chunk types. To change this, you can call:
+
+    png_set_keep_unknown_chunks(png_ptr, keep,
+        chunk_list, num_chunks);
+    keep       - 0: default unknown chunk handling
+                 1: ignore; do not keep
+                 2: keep only if safe-to-copy
+                 3: keep even if unsafe-to-copy
+               You can use these definitions:
+                 PNG_HANDLE_CHUNK_AS_DEFAULT   0
+                 PNG_HANDLE_CHUNK_NEVER        1
+                 PNG_HANDLE_CHUNK_IF_SAFE      2
+                 PNG_HANDLE_CHUNK_ALWAYS       3
+    chunk_list - list of chunks affected (a byte string,
+                 five bytes per chunk, NULL or '\0' if
+                 num_chunks is 0)
+    num_chunks - number of chunks affected; if 0, all
+                 unknown chunks are affected.  If nonzero,
+                 only the chunks in the list are affected
+
+Unknown chunks declared in this way will be saved as raw data onto a
+list of png_unknown_chunk structures.  If a chunk that is normally
+known to libpng is named in the list, it will be handled as unknown,
+according to the "keep" directive.  If a chunk is named in successive
+instances of png_set_keep_unknown_chunks(), the final instance will
+take precedence.  The IHDR and IEND chunks should not be named in
+chunk_list; if they are, libpng will process them normally anyway.
+
+Here is an example of the usage of png_set_keep_unknown_chunks(),
+where the private "vpAg" chunk will later be processed by a user chunk
+callback function:
+
+    png_byte vpAg[5]={118, 112,  65, 103, (png_byte) '\0'};
+
+    #if defined(PNG_UNKNOWN_CHUNKS_SUPPORTED)
+      png_byte unused_chunks[]=
+      {
+        104,  73,  83,  84, (png_byte) '\0',   /* hIST */
+        105,  84,  88, 116, (png_byte) '\0',   /* iTXt */
+        112,  67,  65,  76, (png_byte) '\0',   /* pCAL */
+        115,  67,  65,  76, (png_byte) '\0',   /* sCAL */
+        115,  80,  76,  84, (png_byte) '\0',   /* sPLT */
+        116,  73,  77,  69, (png_byte) '\0',   /* tIME */
+      };
+    #endif
+
+    ...
+
+    #if defined(PNG_UNKNOWN_CHUNKS_SUPPORTED)
+      /* ignore all unknown chunks: */
+      png_set_keep_unknown_chunks(read_ptr, 1, NULL, 0);
+      /* except for vpAg: */
+      png_set_keep_unknown_chunks(read_ptr, 2, vpAg, 1);
+      /* also ignore unused known chunks: */
+      png_set_keep_unknown_chunks(read_ptr, 1, unused_chunks,
+         (int)sizeof(unused_chunks)/5);
+    #endif
+
+.SS User limits
+
+The PNG specification allows the width and height of an image to be as
+large as 2^31-1 (0x7fffffff), or about 2.147 billion rows and columns.
+Since very few applications really need to process such large images,
+we have imposed an arbitrary 1-million limit on rows and columns.
+Larger images will be rejected immediately with a png_error() call. If
+you wish to override this limit, you can use
+
+   png_set_user_limits(png_ptr, width_max, height_max);
+
+to set your own limits, or use width_max = height_max = 0x7fffffffL
+to allow all valid dimensions (libpng may reject some very large images
+anyway because of potential buffer overflow conditions).
+
+You should put this statement after you create the PNG structure and
+before calling png_read_info(), png_read_png(), or png_process_data().
+If you need to retrieve the limits that are being applied, use
+
+   width_max = png_get_user_width_max(png_ptr);
+   height_max = png_get_user_height_max(png_ptr);
+
+The PNG specification sets no limit on the number of ancillary chunks
+allowed in a PNG datastream.  You can impose a limit on the total number
+of sPLT, tEXt, iTXt, zTXt, and unknown chunks that will be stored, with
+
+   png_set_chunk_cache_max(png_ptr, user_chunk_cache_max);
+
+where 0x7fffffffL means unlimited.  You can retrieve this limit with
+
+   chunk_cache_max = png_get_chunk_cache_max(png_ptr);
+
+This limit also applies to the number of buffers that can be allocated
+by png_decompress_chunk() while decompressing iTXt, zTXt, and iCCP chunks.
+
+.SS The high-level read interface
+
+At this point there are two ways to proceed; through the high-level
+read interface, or through a sequence of low-level read operations.
+You can use the high-level interface if (a) you are willing to read
+the entire image into memory, and (b) the input transformations
+you want to do are limited to the following set:
+
+    PNG_TRANSFORM_IDENTITY      No transformation
+    PNG_TRANSFORM_STRIP_16      Strip 16-bit samples to
+                                8 bits
+    PNG_TRANSFORM_STRIP_ALPHA   Discard the alpha channel
+    PNG_TRANSFORM_PACKING       Expand 1, 2 and 4-bit
+                                samples to bytes
+    PNG_TRANSFORM_PACKSWAP      Change order of packed
+                                pixels to LSB first
+    PNG_TRANSFORM_EXPAND        Perform set_expand()
+    PNG_TRANSFORM_INVERT_MONO   Invert monochrome images
+    PNG_TRANSFORM_SHIFT         Normalize pixels to the
+                                sBIT depth
+    PNG_TRANSFORM_BGR           Flip RGB to BGR, RGBA
+                                to BGRA
+    PNG_TRANSFORM_SWAP_ALPHA    Flip RGBA to ARGB or GA
+                                to AG
+    PNG_TRANSFORM_INVERT_ALPHA  Change alpha from opacity
+                                to transparency
+    PNG_TRANSFORM_SWAP_ENDIAN   Byte-swap 16-bit samples
+    PNG_TRANSFORM_GRAY_TO_RGB   Expand grayscale samples
+                                to RGB (or GA to RGBA)
+
+(This excludes setting a background color, doing gamma transformation,
+dithering, and setting filler.)  If this is the case, simply do this:
+
+    png_read_png(png_ptr, info_ptr, png_transforms, NULL)
+
+where png_transforms is an integer containing the bitwise OR of some
+set of transformation flags.  This call is equivalent to png_read_info(),
+followed the set of transformations indicated by the transform mask,
+then png_read_image(), and finally png_read_end().
+
+(The final parameter of this call is not yet used.  Someday it might point
+to transformation parameters required by some future input transform.)
+
+You must use png_transforms and not call any png_set_transform() functions
+when you use png_read_png().
+
+After you have called png_read_png(), you can retrieve the image data
+with
+
+   row_pointers = png_get_rows(png_ptr, info_ptr);
+
+where row_pointers is an array of pointers to the pixel data for each row:
+
+   png_bytep row_pointers[height];
+
+If you know your image size and pixel size ahead of time, you can allocate
+row_pointers prior to calling png_read_png() with
+
+   if (height > PNG_UINT_32_MAX/png_sizeof(png_byte))
+      png_error (png_ptr,
+         "Image is too tall to process in memory");
+   if (width > PNG_UINT_32_MAX/pixel_size)
+      png_error (png_ptr,
+         "Image is too wide to process in memory");
+   row_pointers = png_malloc(png_ptr,
+      height*png_sizeof(png_bytep));
+   for (int i=0; i<height, i++)
+      row_pointers[i]=NULL;  /* security precaution */
+   for (int i=0; i<height, i++)
+      row_pointers[i]=png_malloc(png_ptr,
+         width*pixel_size);
+   png_set_rows(png_ptr, info_ptr, &row_pointers);
+
+Alternatively you could allocate your image in one big block and define
+row_pointers[i] to point into the proper places in your block.
+
+If you use png_set_rows(), the application is responsible for freeing
+row_pointers (and row_pointers[i], if they were separately allocated).
+
+If you don't allocate row_pointers ahead of time, png_read_png() will
+do it, and it'll be free'ed when you call png_destroy_*().
+
+.SS The low-level read interface
+
+If you are going the low-level route, you are now ready to read all
+the file information up to the actual image data.  You do this with a
+call to png_read_info().
+
+    png_read_info(png_ptr, info_ptr);
+
+This will process all chunks up to but not including the image data.
+
+.SS Querying the info structure
+
+Functions are used to get the information from the info_ptr once it
+has been read.  Note that these fields may not be completely filled
+in until png_read_end() has read the chunk data following the image.
+
+    png_get_IHDR(png_ptr, info_ptr, &width, &height,
+       &bit_depth, &color_type, &interlace_type,
+       &compression_type, &filter_method);
+
+    width          - holds the width of the image
+                     in pixels (up to 2^31).
+    height         - holds the height of the image
+                     in pixels (up to 2^31).
+    bit_depth      - holds the bit depth of one of the
+                     image channels.  (valid values are
+                     1, 2, 4, 8, 16 and depend also on
+                     the color_type.  See also
+                     significant bits (sBIT) below).
+    color_type     - describes which color/alpha channels
+                         are present.
+                     PNG_COLOR_TYPE_GRAY
+                        (bit depths 1, 2, 4, 8, 16)
+                     PNG_COLOR_TYPE_GRAY_ALPHA
+                        (bit depths 8, 16)
+                     PNG_COLOR_TYPE_PALETTE
+                        (bit depths 1, 2, 4, 8)
+                     PNG_COLOR_TYPE_RGB
+                        (bit_depths 8, 16)
+                     PNG_COLOR_TYPE_RGB_ALPHA
+                        (bit_depths 8, 16)
+
+                     PNG_COLOR_MASK_PALETTE
+                     PNG_COLOR_MASK_COLOR
+                     PNG_COLOR_MASK_ALPHA
+
+    filter_method  - (must be PNG_FILTER_TYPE_BASE
+                     for PNG 1.0, and can also be
+                     PNG_INTRAPIXEL_DIFFERENCING if
+                     the PNG datastream is embedded in
+                     a MNG-1.0 datastream)
+    compression_type - (must be PNG_COMPRESSION_TYPE_BASE
+                     for PNG 1.0)
+    interlace_type - (PNG_INTERLACE_NONE or
+                     PNG_INTERLACE_ADAM7)
+
+    Any or all of interlace_type, compression_type, or
+    filter_method can be NULL if you are
+    not interested in their values.
+
+    Note that png_get_IHDR() returns 32-bit data into
+    the application's width and height variables.
+    This is an unsafe situation if these are 16-bit
+    variables.  In such situations, the
+    png_get_image_width() and png_get_image_height()
+    functions described below are safer.

+       info_ptr)
+    aspect_ratio = png_get_pixel_aspect_ratio(png_ptr,
+       info_ptr)
+
+   (Each of these returns 0 [signifying "unknown"] if
+       the data is not present or if res_x is 0;
+       res_x_and_y is 0 if res_x != res_y)
+
+The data from the oFFs chunk can be retrieved in several convenient
+forms:
+
+    x_offset = png_get_x_offset_microns(png_ptr, info_ptr);
+    y_offset = png_get_y_offset_microns(png_ptr, info_ptr);

+    y_offset = png_get_y_offset_inches(png_ptr, info_ptr);
+
+   (Each of these returns 0 [signifying "unknown" if both
+       x and y are 0] if the data is not present or if the
+       chunk is present but the unit is the pixel)
+
+For more information, see the png_info definition in png.h and the
+PNG specification for chunk contents.  Be careful with trusting
+rowbytes, as some of the transformations could increase the space
+needed to hold a row (expand, filler, gray_to_rgb, etc.).
+See png_read_update_info(), below.
+
+A quick word about text_ptr and num_text.  PNG stores comments in
+keyword/text pairs, one pair per chunk, with no limit on the number
+of text chunks, and a 2^31 byte limit on their size.  While there are
+suggested keywords, there is no requirement to restrict the use to these
+strings.  It is strongly suggested that keywords and text be sensible
+to humans (that's the point), so don't use abbreviations.  Non-printing
+symbols are not allowed.  See the PNG specification for more details.
+There is also no requirement to have text after the keyword.
+
+Keywords should be limited to 79 Latin-1 characters without leading or
+trailing spaces, but non-consecutive spaces are allowed within the
+keyword.  It is possible to have the same keyword any number of times.
+The text_ptr is an array of png_text structures, each holding a
+pointer to a language string, a pointer to a keyword and a pointer to
+a text string.  The text string, language code, and translated
+keyword may be empty or NULL pointers.  The keyword/text
+pairs are put into the array in the order that they are received.
+However, some or all of the text chunks may be after the image, so, to
+make sure you have read all the text chunks, don't mess with these
+until after you read the stuff after the image.  This will be
+mentioned again below in the discussion that goes with png_read_end().
+
+.SS Input transformations
+
+After you've read the header information, you can set up the library
+to handle any special transformations of the image data.  The various
+ways to transform the data will be described in the order that they
+should occur.  This is important, as some of these change the color
+type and/or bit depth of the data, and some others only work on
+certain color types and bit depths.  Even though each transformation
+checks to see if it has data that it can do something with, you should
+make sure to only enable a transformation if it will be valid for the
+data.  For example, don't swap red and blue on grayscale data.
+
+The colors used for the background and transparency values should be
+supplied in the same format/depth as the current image data.  They
+are stored in the same format/depth as the image data in a bKGD or tRNS
+chunk, so this is what libpng expects for this data.  The colors are
+transformed to keep in sync with the image data when an application
+calls the png_read_update_info() routine (see below).
+
+Data will be decoded into the supplied row buffers packed into bytes
+unless the library has been told to transform it into another format.
+For example, 4 bit/pixel paletted or grayscale data will be returned
+2 pixels/byte with the leftmost pixel in the high-order bits of the
+byte, unless png_set_packing() is called.  8-bit RGB data will be stored
+in RGB RGB RGB format unless png_set_filler() or png_set_add_alpha()
+is called to insert filler bytes, either before or after each RGB triplet.
+16-bit RGB data will be returned RRGGBB RRGGBB, with the most significant
+byte of the color value first, unless png_set_strip_16() is called to
+transform it to regular RGB RGB triplets, or png_set_filler() or
+png_set_add alpha() is called to insert filler bytes, either before or
+after each RRGGBB triplet.  Similarly, 8-bit or 16-bit grayscale data can
+be modified with
+png_set_filler(), png_set_add_alpha(), or png_set_strip_16().
+
+The following code transforms grayscale images of less than 8 to 8 bits,
+changes paletted images to RGB, and adds a full alpha channel if there is
+transparency information in a tRNS chunk.  This is most useful on
+grayscale images with bit depths of 2 or 4 or if there is a multiple-image
+viewing application that wishes to treat all images in the same way.
+
+    if (color_type == PNG_COLOR_TYPE_PALETTE)
+        png_set_palette_to_rgb(png_ptr);
+
+    if (color_type == PNG_COLOR_TYPE_GRAY &&
+        bit_depth < 8) png_set_expand_gray_1_2_4_to_8(png_ptr);
+
+    if (png_get_valid(png_ptr, info_ptr,
+        PNG_INFO_tRNS)) png_set_tRNS_to_alpha(png_ptr);
+
+These three functions are actually aliases for png_set_expand(), added
+in libpng version 1.0.4, with the function names expanded to improve code
+readability.  In some future version they may actually do different
+things.
+
+As of libpng version 1.2.9, png_set_expand_gray_1_2_4_to_8() was
+added.  It expands the sample depth without changing tRNS to alpha.
+
+As of libpng version 1.2.44, not all possible expansions are supported.
+
+In the following table, the 01 means grayscale with depth<8, 31 means
+indexed with depth<8, other numerals represent the color type, "T" means
+the tRNS chunk is present, A means an alpha channel is present, and O
+means tRNS or alpha is present but all pixels in the image are opaque.

+
+PNG can have files with 16 bits per channel.  If you only can handle
+8 bits per channel, this will strip the pixels down to 8 bit.
+
+    if (bit_depth == 16)
+        png_set_strip_16(png_ptr);
+
+If, for some reason, you don't need the alpha channel on an image,
+and you want to remove it rather than combining it with the background
+(but the image author certainly had in mind that you *would* combine
+it with the background, so that's what you should probably do):
+
+    if (color_type & PNG_COLOR_MASK_ALPHA)
+        png_set_strip_alpha(png_ptr);
+
+In PNG files, the alpha channel in an image
+is the level of opacity.  If you need the alpha channel in an image to
+be the level of transparency instead of opacity, you can invert the
+alpha channel (or the tRNS chunk data) after it's read, so that 0 is
+fully opaque and 255 (in 8-bit or paletted images) or 65535 (in 16-bit
+images) is fully transparent, with
+
+    png_set_invert_alpha(png_ptr);
+
+The PNG format only supports pixels with postmultiplied alpha.
+If you want to replace the pixels, after reading them, with pixels
+that have premultiplied color samples, you can do this with
+
+    png_set_premultiply_alpha(png_ptr);
+
+If you do this, any input with a tRNS chunk will be expanded to
+have an alpha channel.
+
+PNG files pack pixels of bit depths 1, 2, and 4 into bytes as small as
+they can, resulting in, for example, 8 pixels per byte for 1 bit
+files.  This code expands to 1 pixel per byte without changing the
+values of the pixels:
+
+    if (bit_depth < 8)
+        png_set_packing(png_ptr);
+
+PNG files have possible bit depths of 1, 2, 4, 8, and 16.  All pixels
+stored in a PNG image have been "scaled" or "shifted" up to the next
+higher possible bit depth (e.g. from 5 bits/sample in the range [0,31]
+to 8 bits/sample in the range [0, 255]).  However, it is also possible
+to convert the PNG pixel data back to the original bit depth of the
+image.  This call reduces the pixels back down to the original bit depth:
+
+    png_color_8p sig_bit;
+
+    if (png_get_sBIT(png_ptr, info_ptr, &sig_bit))
+        png_set_shift(png_ptr, sig_bit);
+
+PNG files store 3-color pixels in red, green, blue order.  This code
+changes the storage of the pixels to blue, green, red:
+
+    if (color_type == PNG_COLOR_TYPE_RGB ||
+        color_type == PNG_COLOR_TYPE_RGB_ALPHA)
+        png_set_bgr(png_ptr);
+
+PNG files store RGB pixels packed into 3 or 6 bytes. This code expands them
+into 4 or 8 bytes for windowing systems that need them in this format:
+
+    if (color_type == PNG_COLOR_TYPE_RGB)
+        png_set_filler(png_ptr, filler, PNG_FILLER_BEFORE);
+
+where "filler" is the 8 or 16-bit number to fill with, and the location is
+either PNG_FILLER_BEFORE or PNG_FILLER_AFTER, depending upon whether
+you want the filler before the RGB or after.  This transformation
+does not affect images that already have full alpha channels.  To add an
+opaque alpha channel, use filler=0xff or 0xffff and PNG_FILLER_AFTER which
+will generate RGBA pixels.
+
+Note that png_set_filler() does not change the color type.  If you want
+to do that, you can add a true alpha channel with
+
+    if (color_type == PNG_COLOR_TYPE_RGB ||
+           color_type == PNG_COLOR_TYPE_GRAY)
+    png_set_add_alpha(png_ptr, filler, PNG_FILLER_AFTER);
+
+where "filler" contains the alpha value to assign to each pixel.
+This function was added in libpng-1.2.7.
+
+If you are reading an image with an alpha channel, and you need the
+data as ARGB instead of the normal PNG format RGBA:
+
+    if (color_type == PNG_COLOR_TYPE_RGB_ALPHA)
+        png_set_swap_alpha(png_ptr);
+
+For some uses, you may want a grayscale image to be represented as
+RGB.  This code will do that conversion:
+
+    if (color_type == PNG_COLOR_TYPE_GRAY ||
+        color_type == PNG_COLOR_TYPE_GRAY_ALPHA)
+          png_set_gray_to_rgb(png_ptr);
+
+Conversely, you can convert an RGB or RGBA image to grayscale or grayscale
+with alpha.
+
+    if (color_type == PNG_COLOR_TYPE_RGB ||
+        color_type == PNG_COLOR_TYPE_RGB_ALPHA)
+          png_set_rgb_to_gray_fixed(png_ptr, error_action,
+             int red_weight, int green_weight);
+
+    error_action = 1: silently do the conversion
+    error_action = 2: issue a warning if the original
+                      image has any pixel where
+                      red != green or red != blue
+    error_action = 3: issue an error and abort the
+                      conversion if the original
+                      image has any pixel where
+                      red != green or red != blue
+
+    red_weight:       weight of red component times 100000
+    green_weight:     weight of green component times 100000
+                      If either weight is negative, default
+                      weights (21268, 71514) are used.
+
+If you have set error_action = 1 or 2, you can
+later check whether the image really was gray, after processing
+the image rows, with the png_get_rgb_to_gray_status(png_ptr) function.
+It will return a png_byte that is zero if the image was gray or
+1 if there were any non-gray pixels.  bKGD and sBIT data
+will be silently converted to grayscale, using the green channel
+data, regardless of the error_action setting.
+
+With red_weight+green_weight<=100000,
+the normalized graylevel is computed:
+
+    int rw = red_weight * 65536;
+    int gw = green_weight * 65536;
+    int bw = 65536 - (rw + gw);
+    gray = (rw*red + gw*green + bw*blue)/65536;

+    Y = 0.212671 * R + 0.715160 * G + 0.072169 * B
+
+Libpng approximates this with
+
+    Y = 0.21268 * R    + 0.7151 * G    + 0.07217 * B
+
+which can be expressed with integers as
+
+    Y = (6969 * R + 23434 * G + 2365 * B)/32768
+
+The calculation is done in a linear colorspace, if the image gamma
+is known.
+
+If you have a grayscale and you are using png_set_expand_depth(),
+png_set_expand(), or png_set_gray_to_rgb to change to truecolor or to
+a higher bit-depth, you must either supply the background color as a gray
+value at the original file bit-depth (need_expand = 1) or else supply the
+background color as an RGB triplet at the final, expanded bit depth
+(need_expand = 0).  Similarly, if you are reading a paletted image, you
+must either supply the background color as a palette index (need_expand = 1)
+or as an RGB triplet that may or may not be in the palette (need_expand = 0).
+
+    png_color_16 my_background;
+    png_color_16p image_background;
+
+    if (png_get_bKGD(png_ptr, info_ptr, &image_background))
+        png_set_background(png_ptr, image_background,
+          PNG_BACKGROUND_GAMMA_FILE, 1, 1.0);
+    else
+        png_set_background(png_ptr, &my_background,
+          PNG_BACKGROUND_GAMMA_SCREEN, 0, 1.0);
+
+The png_set_background() function tells libpng to composite images
+with alpha or simple transparency against the supplied background
+color.  If the PNG file contains a bKGD chunk (PNG_INFO_bKGD valid),
+you may use this color, or supply another color more suitable for
+the current display (e.g., the background color from a web page).  You
+need to tell libpng whether the color is in the gamma space of the
+display (PNG_BACKGROUND_GAMMA_SCREEN for colors you supply), the file
+(PNG_BACKGROUND_GAMMA_FILE for colors from the bKGD chunk), or one
+that is neither of these gammas (PNG_BACKGROUND_GAMMA_UNIQUE - I don't
+know why anyone would use this, but it's here).
+
+To properly display PNG images on any kind of system, the application needs
+to know what the display gamma is.  Ideally, the user will know this, and
+the application will allow them to set it.  One method of allowing the user
+to set the display gamma separately for each system is to check for a
+SCREEN_GAMMA or DISPLAY_GAMMA environment variable, which will hopefully be
+correctly set.
+
+Note that display_gamma is the overall gamma correction required to produce
+pleasing results, which depends on the lighting conditions in the surrounding
+environment.  In a dim or brightly lit room, no compensation other than
+the physical gamma exponent of the monitor is needed, while in a dark room
+a slightly smaller exponent is better.
+
+   double gamma, screen_gamma;
+
+   if (/* We have a user-defined screen
+       gamma value */)
+   {
+      screen_gamma = user_defined_screen_gamma;
+   }
+   /* One way that applications can share the same
+      screen gamma value */
+   else if ((gamma_str = getenv("SCREEN_GAMMA"))
+      != NULL)
+   {
+      screen_gamma = (double)atof(gamma_str);
+   }
+   /* If we don't have another value */
+   else
+   {
+      screen_gamma = 2.2; /* A good guess for a
+           PC monitor in a bright office or a dim room */
+      screen_gamma = 2.0; /* A good guess for a
+           PC monitor in a dark room */
+      screen_gamma = 1.7 or 1.0;  /* A good
+           guess for Mac systems */
+   }
+
+The png_set_gamma() function handles gamma transformations of the data.
+Pass both the file gamma and the current screen_gamma.  If the file does
+not have a gamma value, you can pass one anyway if you have an idea what
+it is (usually 0.45455 is a good guess for GIF images on PCs).  Note
+that file gammas are inverted from screen gammas.  See the discussions
+on gamma in the PNG specification for an excellent description of what
+gamma is, and why all applications should support it.  It is strongly
+recommended that PNG viewers support gamma correction.
+
+   if (png_get_gAMA(png_ptr, info_ptr, &gamma))
+      png_set_gamma(png_ptr, screen_gamma, gamma);
+   else
+      png_set_gamma(png_ptr, screen_gamma, 0.45455);
+
+If you need to reduce an RGB file to a paletted file, or if a paletted
+file has more entries then will fit on your screen, png_set_dither()
+will do that.  Note that this is a simple match dither that merely
+finds the closest color available.  This should work fairly well with
+optimized palettes, and fairly badly with linear color cubes.  If you
+pass a palette that is larger then maximum_colors, the file will
+reduce the number of colors in the palette so it will fit into
+maximum_colors.  If there is a histogram, it will use it to make
+more intelligent choices when reducing the palette.  If there is no
+histogram, it may not do as good a job.
+
+   if (color_type & PNG_COLOR_MASK_COLOR)
+   {
+      if (png_get_valid(png_ptr, info_ptr,
+         PNG_INFO_PLTE))
+      {
+         png_uint_16p histogram = NULL;
+
+         png_get_hIST(png_ptr, info_ptr,
+            &histogram);
+         png_set_dither(png_ptr, palette, num_palette,
+            max_screen_colors, histogram, 1);
+      }
+      else
+      {
+         png_color std_color_cube[MAX_SCREEN_COLORS] =
+            { ... colors ... };
+
+         png_set_dither(png_ptr, std_color_cube,
+            MAX_SCREEN_COLORS, MAX_SCREEN_COLORS,
+            NULL,0);
+      }
+   }
+
+PNG files describe monochrome as black being zero and white being one.
+The following code will reverse this (make black be one and white be
+zero):
+
+   if (bit_depth == 1 && color_type == PNG_COLOR_TYPE_GRAY)
+      png_set_invert_mono(png_ptr);
+
+This function can also be used to invert grayscale and gray-alpha images:
+
+   if (color_type == PNG_COLOR_TYPE_GRAY ||
+        color_type == PNG_COLOR_TYPE_GRAY_ALPHA)
+      png_set_invert_mono(png_ptr);
+
+PNG files store 16 bit pixels in network byte order (big-endian,
+ie. most significant bits first).  This code changes the storage to the
+other way (little-endian, i.e. least significant bits first, the
+way PCs store them):
+
+    if (bit_depth == 16)
+        png_set_swap(png_ptr);
+
+If you are using packed-pixel images (1, 2, or 4 bits/pixel), and you
+need to change the order the pixels are packed into bytes, you can use:
+
+    if (bit_depth < 8)
+       png_set_packswap(png_ptr);
+
+Finally, you can write your own transformation function if none of
+the existing ones meets your needs.  This is done by setting a callback
+with
+
+    png_set_read_user_transform_fn(png_ptr,
+       read_transform_fn);
+
+You must supply the function
+
+    void read_transform_fn(png_ptr ptr, row_info_ptr
+       row_info, png_bytep data)
+
+See pngtest.c for a working example.  Your function will be called
+after all of the other transformations have been processed.
+
+You can also set up a pointer to a user structure for use by your
+callback function, and you can inform libpng that your transform
+function will change the number of channels or bit depth with the
+function
+
+    png_set_user_transform_info(png_ptr, user_ptr,
+       user_depth, user_channels);
+
+The user's application, not libpng, is responsible for allocating and
+freeing any memory required for the user structure.
+
+You can retrieve the pointer via the function
+png_get_user_transform_ptr().  For example:
+
+    voidp read_user_transform_ptr =
+       png_get_user_transform_ptr(png_ptr);
+
+The last thing to handle is interlacing; this is covered in detail below,
+but you must call the function here if you want libpng to handle expansion
+of the interlaced image.
+
+    number_of_passes = png_set_interlace_handling(png_ptr);
+
+After setting the transformations, libpng can update your png_info
+structure to reflect any transformations you've requested with this
+call.  This is most useful to update the info structure's rowbytes
+field so you can use it to allocate your image memory.  This function
+will also update your palette with the correct screen_gamma and
+background if these have been given with the calls above.
+
+    png_read_update_info(png_ptr, info_ptr);
+
+After you call png_read_update_info(), you can allocate any
+memory you need to hold the image.  The row data is simply
+raw byte data for all forms of images.  As the actual allocation
+varies among applications, no example will be given.  If you
+are allocating one large chunk, you will need to build an
+array of pointers to each row, as it will be needed for some
+of the functions below.
+
+.SS Reading image data
+
+After you've allocated memory, you can read the image data.
+The simplest way to do this is in one function call.  If you are
+allocating enough memory to hold the whole image, you can just
+call png_read_image() and libpng will read in all the image data
+and put it in the memory area supplied.  You will need to pass in
+an array of pointers to each row.
+
+This function automatically handles interlacing, so you don't need
+to call png_set_interlace_handling() or call this function multiple
+times, or any of that other stuff necessary with png_read_rows().
+
+   png_read_image(png_ptr, row_pointers);
+
+where row_pointers is:
+
+   png_bytep row_pointers[height];
+
+You can point to void or char or whatever you use for pixels.
+
+If you don't want to read in the whole image at once, you can
+use png_read_rows() instead.  If there is no interlacing (check
+interlace_type == PNG_INTERLACE_NONE), this is simple:
+
+    png_read_rows(png_ptr, row_pointers, NULL,
+       number_of_rows);
+
+where row_pointers is the same as in the png_read_image() call.
+
+If you are doing this just one row at a time, you can do this with
+a single row_pointer instead of an array of row_pointers:
+
+    png_bytep row_pointer = row;
+    png_read_row(png_ptr, row_pointer, NULL);
+
+If the file is interlaced (interlace_type != 0 in the IHDR chunk), things
+get somewhat harder.  The only current (PNG Specification version 1.2)
+interlacing type for PNG is (interlace_type == PNG_INTERLACE_ADAM7)
+is a somewhat complicated 2D interlace scheme, known as Adam7, that
+breaks down an image into seven smaller images of varying size, based
+on an 8x8 grid.
+
+libpng can fill out those images or it can give them to you "as is".
+If you want them filled out, there are two ways to do that.  The one
+mentioned in the PNG specification is to expand each pixel to cover
+those pixels that have not been read yet (the "rectangle" method).
+This results in a blocky image for the first pass, which gradually
+smooths out as more pixels are read.  The other method is the "sparkle"
+method, where pixels are drawn only in their final locations, with the
+rest of the image remaining whatever colors they were initialized to
+before the start of the read.  The first method usually looks better,
+but tends to be slower, as there are more pixels to put in the rows.
+
+If you don't want libpng to handle the interlacing details, just call
+png_read_rows() seven times to read in all seven images.  Each of the
+images is a valid image by itself, or they can all be combined on an
+8x8 grid to form a single image (although if you intend to combine them
+you would be far better off using the libpng interlace handling).
+
+The first pass will return an image 1/8 as wide as the entire image
+(every 8th column starting in column 0) and 1/8 as high as the original
+(every 8th row starting in row 0), the second will be 1/8 as wide
+(starting in column 4) and 1/8 as high (also starting in row 0).  The
+third pass will be 1/4 as wide (every 4th pixel starting in column 0) and
+1/8 as high (every 8th row starting in row 4), and the fourth pass will
+be 1/4 as wide and 1/4 as high (every 4th column starting in column 2,
+and every 4th row starting in row 0).  The fifth pass will return an
+image 1/2 as wide, and 1/4 as high (starting at column 0 and row 2),
+while the sixth pass will be 1/2 as wide and 1/2 as high as the original
+(starting in column 1 and row 0).  The seventh and final pass will be as
+wide as the original, and 1/2 as high, containing all of the odd
+numbered scanlines.  Phew!
+
+If you want libpng to expand the images, call this before calling
+png_start_read_image() or png_read_update_info():
+
+    if (interlace_type == PNG_INTERLACE_ADAM7)
+        number_of_passes
+           = png_set_interlace_handling(png_ptr);
+
+This will return the number of passes needed.  Currently, this
+is seven, but may change if another interlace type is added.
+This function can be called even if the file is not interlaced,
+where it will return one pass.
+
+If you are not going to display the image after each pass, but are
+going to wait until the entire image is read in, use the sparkle
+effect.  This effect is faster and the end result of either method
+is exactly the same.  If you are planning on displaying the image
+after each pass, the "rectangle" effect is generally considered the
+better looking one.
+
+If you only want the "sparkle" effect, just call png_read_rows() as
+normal, with the third parameter NULL.  Make sure you make pass over
+the image number_of_passes times, and you don't change the data in the
+rows between calls.  You can change the locations of the data, just
+not the data.  Each pass only writes the pixels appropriate for that
+pass, and assumes the data from previous passes is still valid.
+
+    png_read_rows(png_ptr, row_pointers, NULL,
+       number_of_rows);
+
+If you only want the first effect (the rectangles), do the same as
+before except pass the row buffer in the third parameter, and leave
+the second parameter NULL.
+
+    png_read_rows(png_ptr, NULL, row_pointers,
+       number_of_rows);
+
+.SS Finishing a sequential read
+
+After you are finished reading the image through the
+low-level interface, you can finish reading the file.  If you are
+interested in comments or time, which may be stored either before or
+after the image data, you should pass the separate png_info struct if
+you want to keep the comments from before and after the image
+separate.  If you are not interested, you can pass NULL.
+
+   png_read_end(png_ptr, end_info);
+
+When you are done, you can free all memory allocated by libpng like this:
+
+   png_destroy_read_struct(&png_ptr, &info_ptr,
+       &end_info);
+
+It is also possible to individually free the info_ptr members that
+point to libpng-allocated storage with the following function:
+
+    png_free_data(png_ptr, info_ptr, mask, seq)
+    mask - identifies data to be freed, a mask
+           containing the bitwise OR of one or
+           more of
+             PNG_FREE_PLTE, PNG_FREE_TRNS,
+             PNG_FREE_HIST, PNG_FREE_ICCP,
+             PNG_FREE_PCAL, PNG_FREE_ROWS,
+             PNG_FREE_SCAL, PNG_FREE_SPLT,
+             PNG_FREE_TEXT, PNG_FREE_UNKN,
+           or simply PNG_FREE_ALL
+    seq  - sequence number of item to be freed
+           (-1 for all items)
+
+This function may be safely called when the relevant storage has
+already been freed, or has not yet been allocated, or was allocated
+by the user and not by libpng,  and will in those cases do nothing.
+The "seq" parameter is ignored if only one item of the selected data
+type, such as PLTE, is allowed.  If "seq" is not -1, and multiple items
+are allowed for the data type identified in the mask, such as text or
+sPLT, only the n'th item in the structure is freed, where n is "seq".
+
+The default behavior is only to free data that was allocated internally
+by libpng.  This can be changed, so that libpng will not free the data,
+or so that it will free data that was allocated by the user with png_malloc()
+or png_zalloc() and passed in via a png_set_*() function, with
+
+    png_data_freer(png_ptr, info_ptr, freer, mask)
+    mask   - which data elements are affected
+             same choices as in png_free_data()
+    freer  - one of
+               PNG_DESTROY_WILL_FREE_DATA
+               PNG_SET_WILL_FREE_DATA
+               PNG_USER_WILL_FREE_DATA
+
+This function only affects data that has already been allocated.
+You can call this function after reading the PNG data but before calling
+any png_set_*() functions, to control whether the user or the png_set_*()
+function is responsible for freeing any existing data that might be present,
+and again after the png_set_*() functions to control whether the user
+or png_destroy_*() is supposed to free the data.  When the user assumes
+responsibility for libpng-allocated data, the application must use
+png_free() to free it, and when the user transfers responsibility to libpng
+for data that the user has allocated, the user must have used png_malloc()
+or png_zalloc() to allocate it.
+
+If you allocated your row_pointers in a single block, as suggested above in
+the description of the high level read interface, you must not transfer
+responsibility for freeing it to the png_set_rows or png_read_destroy function,
+because they would also try to free the individual row_pointers[i].
+
+If you allocated text_ptr.text, text_ptr.lang, and text_ptr.translated_keyword
+separately, do not transfer responsibility for freeing text_ptr to libpng,
+because when libpng fills a png_text structure it combines these members with
+the key member, and png_free_data() will free only text_ptr.key.  Similarly,
+if you transfer responsibility for free'ing text_ptr from libpng to your
+application, your application must not separately free those members.
+
+The png_free_data() function will turn off the "valid" flag for anything
+it frees.  If you need to turn the flag off for a chunk that was freed by
+your application instead of by libpng, you can use
+
+    png_set_invalid(png_ptr, info_ptr, mask);
+    mask - identifies the chunks to be made invalid,
+           containing the bitwise OR of one or
+           more of
+             PNG_INFO_gAMA, PNG_INFO_sBIT,
+             PNG_INFO_cHRM, PNG_INFO_PLTE,
+             PNG_INFO_tRNS, PNG_INFO_bKGD,
+             PNG_INFO_hIST, PNG_INFO_pHYs,
+             PNG_INFO_oFFs, PNG_INFO_tIME,
+             PNG_INFO_pCAL, PNG_INFO_sRGB,
+             PNG_INFO_iCCP, PNG_INFO_sPLT,
+             PNG_INFO_sCAL, PNG_INFO_IDAT
+
+For a more compact example of reading a PNG image, see the file example.c.
+
+.SS Reading PNG files progressively
+
+The progressive reader is slightly different then the non-progressive
+reader.  Instead of calling png_read_info(), png_read_rows(), and
+png_read_end(), you make one call to png_process_data(), which calls
+callbacks when it has the info, a row, or the end of the image.  You
+set up these callbacks with png_set_progressive_read_fn().  You don't
+have to worry about the input/output functions of libpng, as you are
+giving the library the data directly in png_process_data().  I will
+assume that you have read the section on reading PNG files above,
+so I will only highlight the differences (although I will show
+all of the code).
+
+png_structp png_ptr;
+png_infop info_ptr;
+
+ /*  An example code fragment of how you would
+     initialize the progressive reader in your
+     application. */
+ int
+ initialize_png_reader()
+ {

+
+.SH IV. Writing
+
+Much of this is very similar to reading.  However, everything of
+importance is repeated here, so you won't have to constantly look
+back up in the reading section to understand writing.
+
+.SS Setup
+
+You will want to do the I/O initialization before you get into libpng,
+so if it doesn't work, you don't have anything to undo. If you are not
+using the standard I/O functions, you will need to replace them with
+custom writing functions.  See the discussion under Customizing libpng.
+
+    FILE *fp = fopen(file_name, "wb");
+    if (!fp)
+    {
+       return (ERROR);
+    }
+
+Next, png_struct and png_info need to be allocated and initialized.
+As these can be both relatively large, you may not want to store these
+on the stack, unless you have stack space to spare.  Of course, you
+will want to check if they return NULL.  If you are also reading,
+you won't want to name your read structure and your write structure
+both "png_ptr"; you can call them anything you like, such as
+"read_ptr" and "write_ptr".  Look at pngtest.c, for example.
+
+    png_structp png_ptr = png_create_write_struct
+       (PNG_LIBPNG_VER_STRING, (png_voidp)user_error_ptr,
+        user_error_fn, user_warning_fn);
+    if (!png_ptr)
+       return (ERROR);
+
+    png_infop info_ptr = png_create_info_struct(png_ptr);
+    if (!info_ptr)
+    {
+       png_destroy_write_struct(&png_ptr,
+         (png_infopp)NULL);
+       return (ERROR);
+    }
+
+If you want to use your own memory allocation routines,
+define PNG_USER_MEM_SUPPORTED and use
+png_create_write_struct_2() instead of png_create_write_struct():
+
+    png_structp png_ptr = png_create_write_struct_2
+       (PNG_LIBPNG_VER_STRING, (png_voidp)user_error_ptr,
+        user_error_fn, user_warning_fn, (png_voidp)
+        user_mem_ptr, user_malloc_fn, user_free_fn);
+
+After you have these structures, you will need to set up the
+error handling.  When libpng encounters an error, it expects to
+longjmp() back to your routine.  Therefore, you will need to call
+setjmp() and pass the png_jmpbuf(png_ptr).  If you
+write the file from different routines, you will need to update
+the png_jmpbuf(png_ptr) every time you enter a new routine that will
+call a png_*() function.  See your documentation of setjmp/longjmp
+for your compiler for more information on setjmp/longjmp.  See
+the discussion on libpng error handling in the Customizing Libpng
+section below for more information on the libpng error handling.
+
+    if (setjmp(png_jmpbuf(png_ptr)))
+    {
+       png_destroy_write_struct(&png_ptr, &info_ptr);
+       fclose(fp);
+       return (ERROR);
+    }
+    ...
+    return;
+
+If you would rather avoid the complexity of setjmp/longjmp issues,
+you can compile libpng with PNG_SETJMP_NOT_SUPPORTED, in which case
+errors will result in a call to PNG_ABORT() which defaults to abort().
+
+Now you need to set up the output code.  The default for libpng is to
+use the C function fwrite().  If you use this, you will need to pass a
+valid FILE * in the function png_init_io().  Be sure that the file is
+opened in binary mode.  Again, if you wish to handle writing data in
+another way, see the discussion on libpng I/O handling in the Customizing
+Libpng section below.
+
+    png_init_io(png_ptr, fp);
+
+If you are embedding your PNG into a datastream such as MNG, and don't
+want libpng to write the 8-byte signature, or if you have already
+written the signature in your application, use
+
+    png_set_sig_bytes(png_ptr, 8);
+
+to inform libpng that it should not write a signature.
+
+.SS Write callbacks
+
+At this point, you can set up a callback function that will be
+called after each row has been written, which you can use to control
+a progress meter or the like.  It's demonstrated in pngtest.c.
+You must supply a function
+
+    void write_row_callback(png_ptr, png_uint_32 row,
+       int pass);
+    {
+      /* put your code here */
+    }
+
+(You can give it another name that you like instead of "write_row_callback")
+
+To inform libpng about your function, use
+
+    png_set_write_status_fn(png_ptr, write_row_callback);
+
+You now have the option of modifying how the compression library will
+run.  The following functions are mainly for testing, but may be useful
+in some cases, like if you need to write PNG files extremely fast and
+are willing to give up some compression, or if you want to get the
+maximum possible compression at the expense of slower writing.  If you
+have no special needs in this area, let the library do what it wants by
+not calling this function at all, as it has been tuned to deliver a good
+speed/compression ratio. The second parameter to png_set_filter() is
+the filter method, for which the only valid values are 0 (as of the
+July 1999 PNG specification, version 1.2) or 64 (if you are writing
+a PNG datastream that is to be embedded in a MNG datastream).  The third
+parameter is a flag that indicates which filter type(s) are to be tested
+for each scanline.  See the PNG specification for details on the specific
+filter types.
+
+
+    /* turn on or off filtering, and/or choose
+       specific filters.  You can use either a single
+       PNG_FILTER_VALUE_NAME or the bitwise OR of one
+       or more PNG_FILTER_NAME masks. */
+    png_set_filter(png_ptr, 0,
+       PNG_FILTER_NONE  | PNG_FILTER_VALUE_NONE |
+       PNG_FILTER_SUB   | PNG_FILTER_VALUE_SUB  |
+       PNG_FILTER_UP    | PNG_FILTER_VALUE_UP   |
+       PNG_FILTER_AVG   | PNG_FILTER_VALUE_AVG  |
+       PNG_FILTER_PAETH | PNG_FILTER_VALUE_PAETH|
+       PNG_ALL_FILTERS);
+
+If an application
+wants to start and stop using particular filters during compression,
+it should start out with all of the filters (to ensure that the previous
+row of pixels will be stored in case it's needed later), and then add
+and remove them after the start of compression.
+
+If you are writing a PNG datastream that is to be embedded in a MNG
+datastream, the second parameter can be either 0 or 64.
+
+The png_set_compression_*() functions interface to the zlib compression
+library, and should mostly be ignored unless you really know what you are
+doing.  The only generally useful call is png_set_compression_level()
+which changes how much time zlib spends on trying to compress the image
+data.  See the Compression Library (zlib.h and algorithm.txt, distributed
+with zlib) for details on the compression levels.
+
+    /* set the zlib compression level */
+    png_set_compression_level(png_ptr,
+        Z_BEST_COMPRESSION);
+
+    /* set other zlib parameters */
+    png_set_compression_mem_level(png_ptr, 8);
+    png_set_compression_strategy(png_ptr,
+        Z_DEFAULT_STRATEGY);
+    png_set_compression_window_bits(png_ptr, 15);
+    png_set_compression_method(png_ptr, 8);
+    png_set_compression_buffer_size(png_ptr, 8192)
+
+extern PNG_EXPORT(void,png_set_zbuf_size)
+
+.SS Setting the contents of info for output
+
+You now need to fill in the png_info structure with all the data you
+wish to write before the actual image.  Note that the only thing you
+are allowed to write after the image is the text chunks and the time
+chunk (as of PNG Specification 1.2, anyway).  See png_write_end() and
+the latest PNG specification for more information on that.  If you
+wish to write them before the image, fill them in now, and flag that
+data as being valid.  If you want to wait until after the data, don't
+fill them until png_write_end().  For all the fields in png_info and
+their data types, see png.h.  For explanations of what the fields
+contain, see the PNG specification.
+
+Some of the more important parts of the png_info are:
+
+    png_set_IHDR(png_ptr, info_ptr, width, height,
+       bit_depth, color_type, interlace_type,
+       compression_type, filter_method)
+    width          - holds the width of the image
+                     in pixels (up to 2^31).
+    height         - holds the height of the image
+                     in pixels (up to 2^31).
+    bit_depth      - holds the bit depth of one of the
+                     image channels.
+                     (valid values are 1, 2, 4, 8, 16
+                     and depend also on the
+                     color_type.  See also significant
+                     bits (sBIT) below).
+    color_type     - describes which color/alpha
+                     channels are present.
+                     PNG_COLOR_TYPE_GRAY
+                        (bit depths 1, 2, 4, 8, 16)
+                     PNG_COLOR_TYPE_GRAY_ALPHA
+                        (bit depths 8, 16)
+                     PNG_COLOR_TYPE_PALETTE
+                        (bit depths 1, 2, 4, 8)
+                     PNG_COLOR_TYPE_RGB
+                        (bit_depths 8, 16)
+                     PNG_COLOR_TYPE_RGB_ALPHA
+                        (bit_depths 8, 16)
+
+                     PNG_COLOR_MASK_PALETTE
+                     PNG_COLOR_MASK_COLOR
+                     PNG_COLOR_MASK_ALPHA
+
+    interlace_type - PNG_INTERLACE_NONE or
+                     PNG_INTERLACE_ADAM7
+    compression_type - (must be
+                     PNG_COMPRESSION_TYPE_DEFAULT)
+    filter_method  - (must be PNG_FILTER_TYPE_DEFAULT
+                     or, if you are writing a PNG to
+                     be embedded in a MNG datastream,
+                     can also be
+                     PNG_INTRAPIXEL_DIFFERENCING)
+
+If you call png_set_IHDR(), the call must appear before any of the
+other png_set_*() functions, because they might require access to some of
+the IHDR settings.  The remaining png_set_*() functions can be called
+in any order.
+
+If you wish, you can reset the compression_type, interlace_type, or
+filter_method later by calling png_set_IHDR() again; if you do this, the
+width, height, bit_depth, and color_type must be the same in each call.

+                           PNG_AFTER_IDAT: after IDAT
+
+The "location" member is set automatically according to
+what part of the output file has already been written.
+You can change its value after calling png_set_unknown_chunks()
+as demonstrated in pngtest.c.  Within each of the "locations",
+the chunks are sequenced according to their position in the
+structure (that is, the value of "i", which is the order in which
+the chunk was either read from the input file or defined with
+png_set_unknown_chunks).
+
+A quick word about text and num_text.  text is an array of png_text
+structures.  num_text is the number of valid structures in the array.
+Each png_text structure holds a language code, a keyword, a text value,
+and a compression type.
+
+The compression types have the same valid numbers as the compression
+types of the image data.  Currently, the only valid number is zero.
+However, you can store text either compressed or uncompressed, unlike
+images, which always have to be compressed.  So if you don't want the
+text compressed, set the compression type to PNG_TEXT_COMPRESSION_NONE.
+Because tEXt and zTXt chunks don't have a language field, if you
+specify PNG_TEXT_COMPRESSION_NONE or PNG_TEXT_COMPRESSION_zTXt
+any language code or translated keyword will not be written out.
+
+Until text gets around 1000 bytes, it is not worth compressing it.
+After the text has been written out to the file, the compression type
+is set to PNG_TEXT_COMPRESSION_NONE_WR or PNG_TEXT_COMPRESSION_zTXt_WR,
+so that it isn't written out again at the end (in case you are calling
+png_write_end() with the same struct.
+
+The keywords that are given in the PNG Specification are:
+
+    Title            Short (one line) title or
+                     caption for image
+    Author           Name of image's creator
+    Description      Description of image (possibly long)
+    Copyright        Copyright notice
+    Creation Time    Time of original image creation
+                     (usually RFC 1123 format, see below)
+    Software         Software used to create the image
+    Disclaimer       Legal disclaimer
+    Warning          Warning of nature of content
+    Source           Device used to create the image
+    Comment          Miscellaneous comment; conversion
+                     from other image format
+
+The keyword-text pairs work like this.  Keywords should be short
+simple descriptions of what the comment is about.  Some typical
+keywords are found in the PNG specification, as is some recommendations
+on keywords.  You can repeat keywords in a file.  You can even write
+some text before the image and some after.  For example, you may want
+to put a description of the image before the image, but leave the
+disclaimer until after, so viewers working over modem connections
+don't have to wait for the disclaimer to go over the modem before
+they start seeing the image.  Finally, keywords should be full
+words, not abbreviations.  Keywords and text are in the ISO 8859-1
+(Latin-1) character set (a superset of regular ASCII) and can not
+contain NUL characters, and should not contain control or other
+unprintable characters.  To make the comments widely readable, stick
+with basic ASCII, and avoid machine specific character set extensions
+like the IBM-PC character set.  The keyword must be present, but
+you can leave off the text string on non-compressed pairs.
+Compressed pairs must have a text string, as only the text string
+is compressed anyway, so the compression would be meaningless.
+
+PNG supports modification time via the png_time structure.  Two
+conversion routines are provided, png_convert_from_time_t() for
+time_t and png_convert_from_struct_tm() for struct tm.  The
+time_t routine uses gmtime().  You don't have to use either of
+these, but if you wish to fill in the png_time structure directly,
+you should provide the time in universal time (GMT) if possible
+instead of your local time.  Note that the year number is the full
+year (e.g. 1998, rather than 98 - PNG is year 2000 compliant!), and
+that months start with 1.
+
+If you want to store the time of the original image creation, you should
+use a plain tEXt chunk with the "Creation Time" keyword.  This is
+necessary because the "creation time" of a PNG image is somewhat vague,
+depending on whether you mean the PNG file, the time the image was
+created in a non-PNG format, a still photo from which the image was
+scanned, or possibly the subject matter itself.  In order to facilitate
+machine-readable dates, it is recommended that the "Creation Time"
+tEXt chunk use RFC 1123 format dates (e.g. "22 May 1997 18:07:10 GMT"),
+although this isn't a requirement.  Unlike the tIME chunk, the
+"Creation Time" tEXt chunk is not expected to be automatically changed
+by the software.  To facilitate the use of RFC 1123 dates, a function
+png_convert_to_rfc1123(png_timep) is provided to convert from PNG
+time to an RFC 1123 format string.
+
+.SS Writing unknown chunks
+
+You can use the png_set_unknown_chunks function to queue up chunks
+for writing.  You give it a chunk name, raw data, and a size; that's
+all there is to it.  The chunks will be written by the next following
+png_write_info_before_PLTE, png_write_info, or png_write_end function.
+Any chunks previously read into the info structure's unknown-chunk
+list will also be written out in a sequence that satisfies the PNG
+specification's ordering rules.
+
+.SS The high-level write interface
+
+At this point there are two ways to proceed; through the high-level
+write interface, or through a sequence of low-level write operations.
+You can use the high-level interface if your image data is present
+in the info structure.  All defined output
+transformations are permitted, enabled by the following masks.
+
+    PNG_TRANSFORM_IDENTITY      No transformation
+    PNG_TRANSFORM_PACKING       Pack 1, 2 and 4-bit samples
+    PNG_TRANSFORM_PACKSWAP      Change order of packed
+                                pixels to LSB first
+    PNG_TRANSFORM_INVERT_MONO   Invert monochrome images
+    PNG_TRANSFORM_SHIFT         Normalize pixels to the
+                                sBIT depth
+    PNG_TRANSFORM_BGR           Flip RGB to BGR, RGBA
+                                to BGRA
+    PNG_TRANSFORM_SWAP_ALPHA    Flip RGBA to ARGB or GA
+                                to AG
+    PNG_TRANSFORM_INVERT_ALPHA  Change alpha from opacity
+                                to transparency
+    PNG_TRANSFORM_SWAP_ENDIAN   Byte-swap 16-bit samples
+    PNG_TRANSFORM_STRIP_FILLER        Strip out filler
+                                      bytes (deprecated).
+    PNG_TRANSFORM_STRIP_FILLER_BEFORE Strip out leading
+                                      filler bytes
+    PNG_TRANSFORM_STRIP_FILLER_AFTER  Strip out trailing
+                                      filler bytes
+
+If you have valid image data in the info structure (you can use
+png_set_rows() to put image data in the info structure), simply do this:
+
+    png_write_png(png_ptr, info_ptr, png_transforms, NULL)
+
+where png_transforms is an integer containing the bitwise OR of some set of
+transformation flags.  This call is equivalent to png_write_info(),
+followed the set of transformations indicated by the transform mask,
+then png_write_image(), and finally png_write_end().
+
+(The final parameter of this call is not yet used.  Someday it might point
+to transformation parameters required by some future output transform.)
+
+You must use png_transforms and not call any png_set_transform() functions
+when you use png_write_png().
+
+.SS The low-level write interface
+
+If you are going the low-level route instead, you are now ready to
+write all the file information up to the actual image data.  You do
+this with a call to png_write_info().
+
+    png_write_info(png_ptr, info_ptr);
+
+Note that there is one transformation you may need to do before
+png_write_info().  In PNG files, the alpha channel in an image is the
+level of opacity.  If your data is supplied as a level of transparency,
+you can invert the alpha channel before you write it, so that 0 is
+fully transparent and 255 (in 8-bit or paletted images) or 65535
+(in 16-bit images) is fully opaque, with
+
+    png_set_invert_alpha(png_ptr);
+
+This must appear before png_write_info() instead of later with the
+other transformations because in the case of paletted images the tRNS
+chunk data has to be inverted before the tRNS chunk is written.  If
+your image is not a paletted image, the tRNS data (which in such cases
+represents a single color to be rendered as transparent) won't need to
+be changed, and you can safely do this transformation after your
+png_write_info() call.
+
+If you need to write a private chunk that you want to appear before
+the PLTE chunk when PLTE is present, you can write the PNG info in
+two steps, and insert code to write your own chunk between them:
+
+    png_write_info_before_PLTE(png_ptr, info_ptr);
+    png_set_unknown_chunks(png_ptr, info_ptr, ...);
+    png_write_info(png_ptr, info_ptr);
+
+After you've written the file information, you can set up the library
+to handle any special transformations of the image data.  The various
+ways to transform the data will be described in the order that they
+should occur.  This is important, as some of these change the color
+type and/or bit depth of the data, and some others only work on
+certain color types and bit depths.  Even though each transformation
+checks to see if it has data that it can do something with, you should
+make sure to only enable a transformation if it will be valid for the
+data.  For example, don't swap red and blue on grayscale data.
+
+PNG files store RGB pixels packed into 3 or 6 bytes.  This code tells
+the library to strip input data that has 4 or 8 bytes per pixel down
+to 3 or 6 bytes (or strip 2 or 4-byte grayscale+filler data to 1 or 2
+bytes per pixel).
+
+    png_set_filler(png_ptr, 0, PNG_FILLER_BEFORE);
+
+where the 0 is unused, and the location is either PNG_FILLER_BEFORE or
+PNG_FILLER_AFTER, depending upon whether the filler byte in the pixel
+is stored XRGB or RGBX.
+
+PNG files pack pixels of bit depths 1, 2, and 4 into bytes as small as
+they can, resulting in, for example, 8 pixels per byte for 1 bit files.
+If the data is supplied at 1 pixel per byte, use this code, which will
+correctly pack the pixels into a single byte:
+
+    png_set_packing(png_ptr);
+
+PNG files reduce possible bit depths to 1, 2, 4, 8, and 16.  If your
+data is of another bit depth, you can write an sBIT chunk into the
+file so that decoders can recover the original data if desired.
+
+    /* Set the true bit depth of the image data */
+    if (color_type & PNG_COLOR_MASK_COLOR)
+    {
+        sig_bit.red = true_bit_depth;
+        sig_bit.green = true_bit_depth;
+        sig_bit.blue = true_bit_depth;
+    }
+    else
+    {
+        sig_bit.gray = true_bit_depth;
+    }
+    if (color_type & PNG_COLOR_MASK_ALPHA)
+    {
+        sig_bit.alpha = true_bit_depth;
+    }
+
+    png_set_sBIT(png_ptr, info_ptr, &sig_bit);
+
+If the data is stored in the row buffer in a bit depth other than
+one supported by PNG (e.g. 3 bit data in the range 0-7 for a 4-bit PNG),
+this will scale the values to appear to be the correct bit depth as
+is required by PNG.
+
+    png_set_shift(png_ptr, &sig_bit);
+
+PNG files store 16 bit pixels in network byte order (big-endian,
+ie. most significant bits first).  This code would be used if they are
+supplied the other way (little-endian, i.e. least significant bits
+first, the way PCs store them):
+
+    if (bit_depth > 8)
+       png_set_swap(png_ptr);
+
+If you are using packed-pixel images (1, 2, or 4 bits/pixel), and you
+need to change the order the pixels are packed into bytes, you can use:
+
+    if (bit_depth < 8)
+       png_set_packswap(png_ptr);
+
+PNG files store 3 color pixels in red, green, blue order.  This code
+would be used if they are supplied as blue, green, red:
+
+    png_set_bgr(png_ptr);
+
+PNG files describe monochrome as black being zero and white being
+one. This code would be used if the pixels are supplied with this reversed
+(black being one and white being zero):
+
+    png_set_invert_mono(png_ptr);
+
+Finally, you can write your own transformation function if none of
+the existing ones meets your needs.  This is done by setting a callback
+with
+
+    png_set_write_user_transform_fn(png_ptr,
+       write_transform_fn);
+
+You must supply the function
+
+    void write_transform_fn(png_ptr ptr, row_info_ptr
+       row_info, png_bytep data)
+
+See pngtest.c for a working example.  Your function will be called
+before any of the other transformations are processed.
+
+You can also set up a pointer to a user structure for use by your
+callback function.
+
+    png_set_user_transform_info(png_ptr, user_ptr, 0, 0);
+
+The user_channels and user_depth parameters of this function are ignored
+when writing; you can set them to zero as shown.
+
+You can retrieve the pointer via the function png_get_user_transform_ptr().
+For example:
+
+    voidp write_user_transform_ptr =
+       png_get_user_transform_ptr(png_ptr);
+
+It is possible to have libpng flush any pending output, either manually,
+or automatically after a certain number of lines have been written.  To
+flush the output stream a single time call:
+
+    png_write_flush(png_ptr);
+
+and to have libpng flush the output stream periodically after a certain
+number of scanlines have been written, call:
+
+    png_set_flush(png_ptr, nrows);
+
+Note that the distance between rows is from the last time png_write_flush()
+was called, or the first row of the image if it has never been called.
+So if you write 50 lines, and then png_set_flush 25, it will flush the
+output on the next scanline, and every 25 lines thereafter, unless
+png_write_flush() is called before 25 more lines have been written.
+If nrows is too small (less than about 10 lines for a 640 pixel wide
+RGB image) the image compression may decrease noticeably (although this
+may be acceptable for real-time applications).  Infrequent flushing will
+only degrade the compression performance by a few percent over images
+that do not use flushing.
+
+.SS Writing the image data
+
+That's it for the transformations.  Now you can write the image data.
+The simplest way to do this is in one function call.  If you have the
+whole image in memory, you can just call png_write_image() and libpng
+will write the image.  You will need to pass in an array of pointers to
+each row.  This function automatically handles interlacing, so you don't
+need to call png_set_interlace_handling() or call this function multiple
+times, or any of that other stuff necessary with png_write_rows().
+
+    png_write_image(png_ptr, row_pointers);
+
+where row_pointers is:
+
+    png_byte *row_pointers[height];
+
+You can point to void or char or whatever you use for pixels.
+
+If you don't want to write the whole image at once, you can
+use png_write_rows() instead.  If the file is not interlaced,
+this is simple:
+
+    png_write_rows(png_ptr, row_pointers,
+       number_of_rows);
+
+row_pointers is the same as in the png_write_image() call.
+
+If you are just writing one row at a time, you can do this with
+a single row_pointer instead of an array of row_pointers:
+
+    png_bytep row_pointer = row;
+
+    png_write_row(png_ptr, row_pointer);
+
+When the file is interlaced, things can get a good deal more complicated.
+The only currently (as of the PNG Specification version 1.2, dated July
+1999) defined interlacing scheme for PNG files is the "Adam7" interlace
+scheme, that breaks down an image into seven smaller images of varying
+size.  libpng will build these images for you, or you can do them
+yourself.  If you want to build them yourself, see the PNG specification
+for details of which pixels to write when.
+
+If you don't want libpng to handle the interlacing details, just
+use png_set_interlace_handling() and call png_write_rows() the
+correct number of times to write all seven sub-images.
+
+If you want libpng to build the sub-images, call this before you start
+writing any rows:
+
+    number_of_passes =
+       png_set_interlace_handling(png_ptr);
+
+This will return the number of passes needed.  Currently, this is seven,
+but may change if another interlace type is added.
+
+Then write the complete image number_of_passes times.
+
+    png_write_rows(png_ptr, row_pointers,
+       number_of_rows);
+
+As some of these rows are not used, and thus return immediately, you may
+want to read about interlacing in the PNG specification, and only update
+the rows that are actually used.
+
+.SS Finishing a sequential write
+
+After you are finished writing the image, you should finish writing
+the file.  If you are interested in writing comments or time, you should
+pass an appropriately filled png_info pointer.  If you are not interested,
+you can pass NULL.
+
+    png_write_end(png_ptr, info_ptr);
+
+When you are done, you can free all memory used by libpng like this:
+
+    png_destroy_write_struct(&png_ptr, &info_ptr);
+
+It is also possible to individually free the info_ptr members that
+point to libpng-allocated storage with the following function:
+
+    png_free_data(png_ptr, info_ptr, mask, seq)
+    mask  - identifies data to be freed, a mask
+            containing the bitwise OR of one or
+            more of
+              PNG_FREE_PLTE, PNG_FREE_TRNS,
+              PNG_FREE_HIST, PNG_FREE_ICCP,
+              PNG_FREE_PCAL, PNG_FREE_ROWS,
+              PNG_FREE_SCAL, PNG_FREE_SPLT,
+              PNG_FREE_TEXT, PNG_FREE_UNKN,
+            or simply PNG_FREE_ALL
+    seq   - sequence number of item to be freed
+            (-1 for all items)
+
+This function may be safely called when the relevant storage has
+already been freed, or has not yet been allocated, or was allocated
+by the user  and not by libpng,  and will in those cases do nothing.
+The "seq" parameter is ignored if only one item of the selected data
+type, such as PLTE, is allowed.  If "seq" is not -1, and multiple items
+are allowed for the data type identified in the mask, such as text or
+sPLT, only the n'th item in the structure is freed, where n is "seq".
+
+If you allocated data such as a palette that you passed in to libpng
+with png_set_*, you must not free it until just before the call to
+png_destroy_write_struct().
+
+The default behavior is only to free data that was allocated internally
+by libpng.  This can be changed, so that libpng will not free the data,
+or so that it will free data that was allocated by the user with png_malloc()
+or png_zalloc() and passed in via a png_set_*() function, with
+
+    png_data_freer(png_ptr, info_ptr, freer, mask)
+    mask   - which data elements are affected
+             same choices as in png_free_data()
+    freer  - one of
+               PNG_DESTROY_WILL_FREE_DATA
+               PNG_SET_WILL_FREE_DATA
+               PNG_USER_WILL_FREE_DATA
+
+For example, to transfer responsibility for some data from a read structure
+to a write structure, you could use
+
+    png_data_freer(read_ptr, read_info_ptr,
+       PNG_USER_WILL_FREE_DATA,
+       PNG_FREE_PLTE|PNG_FREE_tRNS|PNG_FREE_hIST)
+    png_data_freer(write_ptr, write_info_ptr,
+       PNG_DESTROY_WILL_FREE_DATA,
+       PNG_FREE_PLTE|PNG_FREE_tRNS|PNG_FREE_hIST)
+
+thereby briefly reassigning responsibility for freeing to the user but
+immediately afterwards reassigning it once more to the write_destroy
+function.  Having done this, it would then be safe to destroy the read
+structure and continue to use the PLTE, tRNS, and hIST data in the write
+structure.
+
+This function only affects data that has already been allocated.
+You can call this function before calling after the png_set_*() functions
+to control whether the user or png_destroy_*() is supposed to free the data.
+When the user assumes responsibility for libpng-allocated data, the
+application must use
+png_free() to free it, and when the user transfers responsibility to libpng
+for data that the user has allocated, the user must have used png_malloc()
+or png_zalloc() to allocate it.
+
+If you allocated text_ptr.text, text_ptr.lang, and text_ptr.translated_keyword
+separately, do not transfer responsibility for freeing text_ptr to libpng,
+because when libpng fills a png_text structure it combines these members with
+the key member, and png_free_data() will free only text_ptr.key.  Similarly,
+if you transfer responsibility for free'ing text_ptr from libpng to your
+application, your application must not separately free those members.
+For a more compact example of writing a PNG image, see the file example.c.
+
+.SH V. Modifying/Customizing libpng:
+
+There are two issues here.  The first is changing how libpng does
+standard things like memory allocation, input/output, and error handling.
+The second deals with more complicated things like adding new chunks,
+adding new transformations, and generally changing how libpng works.
+Both of those are compile-time issues; that is, they are generally
+determined at the time the code is written, and there is rarely a need
+to provide the user with a means of changing them.
+
+Memory allocation, input/output, and error handling
+
+All of the memory allocation, input/output, and error handling in libpng
+goes through callbacks that are user-settable.  The default routines are
+in pngmem.c, pngrio.c, pngwio.c, and pngerror.c, respectively.  To change
+these functions, call the appropriate png_set_*_fn() function.
+
+Memory allocation is done through the functions png_malloc(), png_calloc(),
+and png_free().  These currently just call the standard C functions.
+png_calloc() calls png_malloc() and then png_memset() to clear the newly
+allocated memory to zero.  If your pointers can't access more then 64K
+at a time, you will want to set MAXSEG_64K in zlib.h.  Since it is
+unlikely that the method of handling memory allocation on a platform
+will change between applications, these functions must be modified in
+the library at compile time.  If you prefer to use a different method
+of allocating and freeing data, you can use png_create_read_struct_2() or
+png_create_write_struct_2() to register your own functions as described
+above.  These functions also provide a void pointer that can be retrieved
+via
+
+    mem_ptr=png_get_mem_ptr(png_ptr);
+
+Your replacement memory functions must have prototypes as follows:
+
+    png_voidp malloc_fn(png_structp png_ptr,
+       png_size_t size);
+    void free_fn(png_structp png_ptr, png_voidp ptr);
+
+Your malloc_fn() must return NULL in case of failure.  The png_malloc()
+function will normally call png_error() if it receives a NULL from the
+system memory allocator or from your replacement malloc_fn().
+
+Your free_fn() will never be called with a NULL ptr, since libpng's
+png_free() checks for NULL before calling free_fn().
+
+Input/Output in libpng is done through png_read() and png_write(),
+which currently just call fread() and fwrite().  The FILE * is stored in
+png_struct and is initialized via png_init_io().  If you wish to change
+the method of I/O, the library supplies callbacks that you can set
+through the function png_set_read_fn() and png_set_write_fn() at run
+time, instead of calling the png_init_io() function.  These functions
+also provide a void pointer that can be retrieved via the function
+png_get_io_ptr().  For example:
+
+    png_set_read_fn(png_structp read_ptr,
+        voidp read_io_ptr, png_rw_ptr read_data_fn)
+
+    png_set_write_fn(png_structp write_ptr,
+        voidp write_io_ptr, png_rw_ptr write_data_fn,
+        png_flush_ptr output_flush_fn);
+
+    voidp read_io_ptr = png_get_io_ptr(read_ptr);
+    voidp write_io_ptr = png_get_io_ptr(write_ptr);
+
+The replacement I/O functions must have prototypes as follows:
+
+    void user_read_data(png_structp png_ptr,
+        png_bytep data, png_size_t length);
+    void user_write_data(png_structp png_ptr,
+        png_bytep data, png_size_t length);
+    void user_flush_data(png_structp png_ptr);
+
+The user_read_data() function is responsible for detecting and
+handling end-of-data errors.
+
+Supplying NULL for the read, write, or flush functions sets them back
+to using the default C stream functions, which expect the io_ptr to
+point to a standard *FILE structure.  It is probably a mistake
+to use NULL for one of write_data_fn and output_flush_fn but not both
+of them, unless you have built libpng with PNG_NO_WRITE_FLUSH defined.
+It is an error to read from a write stream, and vice versa.
+
+Error handling in libpng is done through png_error() and png_warning().
+Errors handled through png_error() are fatal, meaning that png_error()
+should never return to its caller.  Currently, this is handled via
+setjmp() and longjmp() (unless you have compiled libpng with
+PNG_SETJMP_NOT_SUPPORTED, in which case it is handled via PNG_ABORT()),
+but you could change this to do things like exit() if you should wish.
+
+On non-fatal errors, png_warning() is called
+to print a warning message, and then control returns to the calling code.
+By default png_error() and png_warning() print a message on stderr via
+fprintf() unless the library is compiled with PNG_NO_CONSOLE_IO defined
+(because you don't want the messages) or PNG_NO_STDIO defined (because
+fprintf() isn't available).  If you wish to change the behavior of the error
+functions, you will need to set up your own message callbacks.  These
+functions are normally supplied at the time that the png_struct is created.
+It is also possible to redirect errors and warnings to your own replacement
+functions after png_create_*_struct() has been called by calling:
+
+    png_set_error_fn(png_structp png_ptr,
+        png_voidp error_ptr, png_error_ptr error_fn,
+        png_error_ptr warning_fn);
+
+    png_voidp error_ptr = png_get_error_ptr(png_ptr);
+
+If NULL is supplied for either error_fn or warning_fn, then the libpng
+default function will be used, calling fprintf() and/or longjmp() if a
+problem is encountered.  The replacement error functions should have
+parameters as follows:
+
+    void user_error_fn(png_structp png_ptr,
+        png_const_charp error_msg);
+    void user_warning_fn(png_structp png_ptr,
+        png_const_charp warning_msg);
+
+The motivation behind using setjmp() and longjmp() is the C++ throw and
+catch exception handling methods.  This makes the code much easier to write,
+as there is no need to check every return code of every function call.
+However, there are some uncertainties about the status of local variables
+after a longjmp, so the user may want to be careful about doing anything
+after setjmp returns non-zero besides returning itself.  Consult your
+compiler documentation for more details.  For an alternative approach, you
+may wish to use the "cexcept" facility (see http://cexcept.sourceforge.net).
+
+.SS Custom chunks
+
+If you need to read or write custom chunks, you may need to get deeper
+into the libpng code.  The library now has mechanisms for storing
+and writing chunks of unknown type; you can even declare callbacks
+for custom chunks.  However, this may not be good enough if the
+library code itself needs to know about interactions between your
+chunk and existing `intrinsic' chunks.
+
+If you need to write a new intrinsic chunk, first read the PNG
+specification. Acquire a first level of understanding of how it works.
+Pay particular attention to the sections that describe chunk names,
+and look at how other chunks were designed, so you can do things
+similarly.  Second, check out the sections of libpng that read and
+write chunks.  Try to find a chunk that is similar to yours and use
+it as a template.  More details can be found in the comments inside
+the code.  It is best to handle unknown chunks in a generic method,
+via callback functions, instead of by modifying libpng functions.
+
+If you wish to write your own transformation for the data, look through
+the part of the code that does the transformations, and check out some of
+the simpler ones to get an idea of how they work.  Try to find a similar
+transformation to the one you want to add and copy off of it.  More details
+can be found in the comments inside the code itself.
+
+.SS Configuring for 16 bit platforms
+
+You will want to look into zconf.h to tell zlib (and thus libpng) that
+it cannot allocate more then 64K at a time.  Even if you can, the memory
+won't be accessible.  So limit zlib and libpng to 64K by defining MAXSEG_64K.
+
+.SS Configuring for DOS
+
+For DOS users who only have access to the lower 640K, you will
+have to limit zlib's memory usage via a png_set_compression_mem_level()
+call.  See zlib.h or zconf.h in the zlib library for more information.
+
+.SS Configuring for Medium Model
+
+Libpng's support for medium model has been tested on most of the popular
+compilers.  Make sure MAXSEG_64K gets defined, USE_FAR_KEYWORD gets
+defined, and FAR gets defined to far in pngconf.h, and you should be
+all set.  Everything in the library (except for zlib's structure) is
+expecting far data.  You must use the typedefs with the p or pp on
+the end for pointers (or at least look at them and be careful).  Make
+note that the rows of data are defined as png_bytepp, which is an
+unsigned char far * far *.
+
+.SS Configuring for gui/windowing platforms:
+
+You will need to write new error and warning functions that use the GUI
+interface, as described previously, and set them to be the error and
+warning functions at the time that png_create_*_struct() is called,
+in order to have them available during the structure initialization.
+They can be changed later via png_set_error_fn().  On some compilers,
+you may also have to change the memory allocators (png_malloc, etc.).
+
+.SS Configuring for compiler xxx:
+
+All includes for libpng are in pngconf.h.  If you need to add, change
+or delete an include, this is the place to do it.
+The includes that are not needed outside libpng are protected by the
+PNG_INTERNAL definition, which is only defined for those routines inside
+libpng itself.  The files in libpng proper only include png.h, which
+includes pngconf.h.
+
+.SS Configuring zlib:
+
+There are special functions to configure the compression.  Perhaps the
+most useful one changes the compression level, which currently uses
+input compression values in the range 0 - 9.  The library normally
+uses the default compression level (Z_DEFAULT_COMPRESSION = 6).  Tests
+have shown that for a large majority of images, compression values in
+the range 3-6 compress nearly as well as higher levels, and do so much
+faster.  For online applications it may be desirable to have maximum speed
+(Z_BEST_SPEED = 1).  With versions of zlib after v0.99, you can also
+specify no compression (Z_NO_COMPRESSION = 0), but this would create
+files larger than just storing the raw bitmap.  You can specify the
+compression level by calling:
+
+    png_set_compression_level(png_ptr, level);
+
+Another useful one is to reduce the memory level used by the library.
+The memory level defaults to 8, but it can be lowered if you are
+short on memory (running DOS, for example, where you only have 640K).
+Note that the memory level does have an effect on compression; among
+other things, lower levels will result in sections of incompressible
+data being emitted in smaller stored blocks, with a correspondingly
+larger relative overhead of up to 15% in the worst case.
+
+    png_set_compression_mem_level(png_ptr, level);
+
+The other functions are for configuring zlib.  They are not recommended
+for normal use and may result in writing an invalid PNG file.  See
+zlib.h for more information on what these mean.
+
+    png_set_compression_strategy(png_ptr,
+        strategy);
+    png_set_compression_window_bits(png_ptr,
+        window_bits);
+    png_set_compression_method(png_ptr, method);
+    png_set_compression_buffer_size(png_ptr, size);
+
+.SS Controlling row filtering
+
+If you want to control whether libpng uses filtering or not, which
+filters are used, and how it goes about picking row filters, you
+can call one of these functions.  The selection and configuration
+of row filters can have a significant impact on the size and
+encoding speed and a somewhat lesser impact on the decoding speed
+of an image.  Filtering is enabled by default for RGB and grayscale
+images (with and without alpha), but not for paletted images nor
+for any images with bit depths less than 8 bits/pixel.
+
+The 'method' parameter sets the main filtering method, which is
+currently only '0' in the PNG 1.2 specification.  The 'filters'
+parameter sets which filter(s), if any, should be used for each
+scanline.  Possible values are PNG_ALL_FILTERS and PNG_NO_FILTERS
+to turn filtering on and off, respectively.
+
+Individual filter types are PNG_FILTER_NONE, PNG_FILTER_SUB,
+PNG_FILTER_UP, PNG_FILTER_AVG, PNG_FILTER_PAETH, which can be bitwise
+ORed together with '|' to specify one or more filters to use.
+These filters are described in more detail in the PNG specification.
+If you intend to change the filter type during the course of writing
+the image, you should start with flags set for all of the filters
+you intend to use so that libpng can initialize its internal
+structures appropriately for all of the filter types.  (Note that this
+means the first row must always be adaptively filtered, because libpng
+currently does not allocate the filter buffers until png_write_row()
+is called for the first time.)
+
+    filters = PNG_FILTER_NONE | PNG_FILTER_SUB
+              PNG_FILTER_UP | PNG_FILTER_AVG |
+              PNG_FILTER_PAETH | PNG_ALL_FILTERS;
+
+    png_set_filter(png_ptr, PNG_FILTER_TYPE_BASE,
+       filters);
+              The second parameter can also be
+              PNG_INTRAPIXEL_DIFFERENCING if you are
+              writing a PNG to be embedded in a MNG
+              datastream.  This parameter must be the
+              same as the value of filter_method used
+              in png_set_IHDR().
+
+It is also possible to influence how libpng chooses from among the
+available filters.  This is done in one or both of two ways - by
+telling it how important it is to keep the same filter for successive
+rows, and by telling it the relative computational costs of the filters.
+
+    double weights[3] = {1.5, 1.3, 1.1},
+       costs[PNG_FILTER_VALUE_LAST] =
+       {1.0, 1.3, 1.3, 1.5, 1.7};
+
+    png_set_filter_heuristics(png_ptr,
+       PNG_FILTER_HEURISTIC_WEIGHTED, 3,
+       weights, costs);
+
+The weights are multiplying factors that indicate to libpng that the
+row filter should be the same for successive rows unless another row filter
+is that many times better than the previous filter.  In the above example,
+if the previous 3 filters were SUB, SUB, NONE, the SUB filter could have a
+"sum of absolute differences" 1.5 x 1.3 times higher than other filters
+and still be chosen, while the NONE filter could have a sum 1.1 times
+higher than other filters and still be chosen.  Unspecified weights are
+taken to be 1.0, and the specified weights should probably be declining
+like those above in order to emphasize recent filters over older filters.
+
+The filter costs specify for each filter type a relative decoding cost
+to be considered when selecting row filters.  This means that filters
+with higher costs are less likely to be chosen over filters with lower
+costs, unless their "sum of absolute differences" is that much smaller.
+The costs do not necessarily reflect the exact computational speeds of
+the various filters, since this would unduly influence the final image
+size.
+
+Note that the numbers above were invented purely for this example and
+are given only to help explain the function usage.  Little testing has
+been done to find optimum values for either the costs or the weights.
+
+.SS Removing unwanted object code
+
+There are a bunch of #define's in pngconf.h that control what parts of
+libpng are compiled.  All the defines end in _SUPPORTED.  If you are
+never going to use a capability, you can change the #define to #undef
+before recompiling libpng and save yourself code and data space, or
+you can turn off individual capabilities with defines that begin with
+PNG_NO_.
+
+You can also turn all of the transforms and ancillary chunk capabilities
+off en masse with compiler directives that define
+PNG_NO_READ[or WRITE]_TRANSFORMS, or PNG_NO_READ[or WRITE]_ANCILLARY_CHUNKS,
+or all four,
+along with directives to turn on any of the capabilities that you do
+want.  The PNG_NO_READ[or WRITE]_TRANSFORMS directives disable the extra
+transformations but still leave the library fully capable of reading
+and writing PNG files with all known public chunks. Use of the
+PNG_NO_READ[or WRITE]_ANCILLARY_CHUNKS directive produces a library
+that is incapable of reading or writing ancillary chunks.  If you are
+not using the progressive reading capability, you can turn that off
+with PNG_NO_PROGRESSIVE_READ (don't confuse this with the INTERLACING
+capability, which you'll still have).
+
+All the reading and writing specific code are in separate files, so the
+linker should only grab the files it needs.  However, if you want to
+make sure, or if you are building a stand alone library, all the
+reading files start with pngr and all the writing files start with
+pngw.  The files that don't match either (like png.c, pngtrans.c, etc.)
+are used for both reading and writing, and always need to be included.
+The progressive reader is in pngpread.c
+
+If you are creating or distributing a dynamically linked library (a .so
+or DLL file), you should not remove or disable any parts of the library,
+as this will cause applications linked with different versions of the
+library to fail if they call functions not available in your library.
+The size of the library itself should not be an issue, because only
+those sections that are actually used will be loaded into memory.
+
+.SS Requesting debug printout
+
+The macro definition PNG_DEBUG can be used to request debugging
+printout.  Set it to an integer value in the range 0 to 3.  Higher
+numbers result in increasing amounts of debugging information.  The
+information is printed to the "stderr" file, unless another file
+name is specified in the PNG_DEBUG_FILE macro definition.
+
+When PNG_DEBUG > 0, the following functions (macros) become available:
+
+   png_debug(level, message)
+   png_debug1(level, message, p1)
+   png_debug2(level, message, p1, p2)
+
+in which "level" is compared to PNG_DEBUG to decide whether to print
+the message, "message" is the formatted string to be printed,
+and p1 and p2 are parameters that are to be embedded in the string
+according to printf-style formatting directives.  For example,
+
+   png_debug1(2, "foo=%d\n", foo);
+
+is expanded to
+
+   if(PNG_DEBUG > 2)
+     fprintf(PNG_DEBUG_FILE, "foo=%d\n", foo);
+
+When PNG_DEBUG is defined but is zero, the macros aren't defined, but you
+can still use PNG_DEBUG to control your own debugging:
+
+   #ifdef PNG_DEBUG
+       fprintf(stderr, ...
+   #endif
+
+When PNG_DEBUG = 1, the macros are defined, but only png_debug statements
+having level = 0 will be printed.  There aren't any such statements in
+this version of libpng, but if you insert some they will be printed.
+
+.SH VI.  MNG support
+
+The MNG specification (available at http://www.libpng.org/pub/mng) allows
+certain extensions to PNG for PNG images that are embedded in MNG datastreams.
+Libpng can support some of these extensions.  To enable them, use the
+png_permit_mng_features() function:
+
+   feature_set = png_permit_mng_features(png_ptr, mask)
+   mask is a png_uint_32 containing the bitwise OR of the
+        features you want to enable.  These include
+        PNG_FLAG_MNG_EMPTY_PLTE
+        PNG_FLAG_MNG_FILTER_64
+        PNG_ALL_MNG_FEATURES
+   feature_set is a png_uint_32 that is the bitwise AND of
+      your mask with the set of MNG features that is
+      supported by the version of libpng that you are using.
+
+It is an error to use this function when reading or writing a standalone
+PNG file with the PNG 8-byte signature.  The PNG datastream must be wrapped
+in a MNG datastream.  As a minimum, it must have the MNG 8-byte signature
+and the MHDR and MEND chunks.  Libpng does not provide support for these
+or any other MNG chunks; your application must provide its own support for
+them.  You may wish to consider using libmng (available at
+http://www.libmng.com) instead.
+
+.SH VII.  Changes to Libpng from version 0.88
+
+It should be noted that versions of libpng later than 0.96 are not
+distributed by the original libpng author, Guy Schalnat, nor by
+Andreas Dilger, who had taken over from Guy during 1996 and 1997, and
+distributed versions 0.89 through 0.96, but rather by another member
+of the original PNG Group, Glenn Randers-Pehrson.  Guy and Andreas are
+still alive and well, but they have moved on to other things.
+
+The old libpng functions png_read_init(), png_write_init(),
+png_info_init(), png_read_destroy(), and png_write_destroy() have been
+moved to PNG_INTERNAL in version 0.95 to discourage their use.  These
+functions will be removed from libpng version 2.0.0.
+
+The preferred method of creating and initializing the libpng structures is
+via the png_create_read_struct(), png_create_write_struct(), and
+png_create_info_struct() because they isolate the size of the structures
+from the application, allow version error checking, and also allow the
+use of custom error handling routines during the initialization, which
+the old functions do not.  The functions png_read_destroy() and
+png_write_destroy() do not actually free the memory that libpng
+allocated for these structs, but just reset the data structures, so they
+can be used instead of png_destroy_read_struct() and
+png_destroy_write_struct() if you feel there is too much system overhead
+allocating and freeing the png_struct for each image read.
+
+Setting the error callbacks via png_set_message_fn() before
+png_read_init() as was suggested in libpng-0.88 is no longer supported
+because this caused applications that do not use custom error functions
+to fail if the png_ptr was not initialized to zero.  It is still possible
+to set the error callbacks AFTER png_read_init(), or to change them with
+png_set_error_fn(), which is essentially the same function, but with a new
+name to force compilation errors with applications that try to use the old
+method.
+
+Starting with version 1.0.7, you can find out which version of the library
+you are using at run-time:
+
+   png_uint_32 libpng_vn = png_access_version_number();
+
+The number libpng_vn is constructed from the major version, minor
+version with leading zero, and release number with leading zero,
+(e.g., libpng_vn for version 1.0.7 is 10007).
+
+You can also check which version of png.h you used when compiling your
+application:
+
+   png_uint_32 application_vn = PNG_LIBPNG_VER;
+
+.SH VIII.  Changes to Libpng from version 1.0.x to 1.2.x
+
+Support for user memory management was enabled by default.  To
+accomplish this, the functions png_create_read_struct_2(),
+png_create_write_struct_2(), png_set_mem_fn(), png_get_mem_ptr(),
+png_malloc_default(), and png_free_default() were added.
+
+Support for the iTXt chunk has been enabled by default as of
+version 1.2.41.
+
+Support for certain MNG features was enabled.
+
+Support for numbered error messages was added.  However, we never got
+around to actually numbering the error messages.  The function
+png_set_strip_error_numbers() was added (Note: the prototype for this
+function was inadvertently removed from png.h in PNG_NO_ASSEMBLER_CODE
+builds of libpng-1.2.15.  It was restored in libpng-1.2.36).
+
+The png_malloc_warn() function was added at libpng-1.2.3.  This issues
+a png_warning and returns NULL instead of aborting when it fails to
+acquire the requested memory allocation.
+
+Support for setting user limits on image width and height was enabled
+by default.  The functions png_set_user_limits(), png_get_user_width_max(),
+and png_get_user_height_max() were added at libpng-1.2.6.
+
+The png_set_add_alpha() function was added at libpng-1.2.7.
+
+The function png_set_expand_gray_1_2_4_to_8() was added at libpng-1.2.9.
+Unlike png_set_gray_1_2_4_to_8(), the new function does not expand the
+tRNS chunk to alpha. The png_set_gray_1_2_4_to_8() function is
+deprecated.
+
+A number of macro definitions in support of runtime selection of
+assembler code features (especially Intel MMX code support) were
+added at libpng-1.2.0:
+
+    PNG_ASM_FLAG_MMX_SUPPORT_COMPILED
+    PNG_ASM_FLAG_MMX_SUPPORT_IN_CPU
+    PNG_ASM_FLAG_MMX_READ_COMBINE_ROW
+    PNG_ASM_FLAG_MMX_READ_INTERLACE
+    PNG_ASM_FLAG_MMX_READ_FILTER_SUB

+    PNG_MMX_READ_FLAGS
+    PNG_MMX_FLAGS
+    PNG_MMX_WRITE_FLAGS
+    PNG_MMX_FLAGS
+
+We added the following functions in support of runtime
+selection of assembler code features:
+
+    png_get_mmx_flagmask()
+    png_set_mmx_thresholds()
+    png_get_asm_flags()
+    png_get_mmx_bitdepth_threshold()
+    png_get_mmx_rowbytes_threshold()
+    png_set_asm_flags()
+
+We replaced all of these functions with simple stubs in libpng-1.2.20,
+when the Intel assembler code was removed due to a licensing issue.
+
+These macros are deprecated:
+
+    PNG_READ_TRANSFORMS_NOT_SUPPORTED
+    PNG_PROGRESSIVE_READ_NOT_SUPPORTED
+    PNG_NO_SEQUENTIAL_READ_SUPPORTED
+    PNG_WRITE_TRANSFORMS_NOT_SUPPORTED
+    PNG_READ_ANCILLARY_CHUNKS_NOT_SUPPORTED
+    PNG_WRITE_ANCILLARY_CHUNKS_NOT_SUPPORTED
+
+They have been replaced, respectively, by:
+
+    PNG_NO_READ_TRANSFORMS
+    PNG_NO_PROGRESSIVE_READ
+    PNG_NO_SEQUENTIAL_READ
+    PNG_NO_WRITE_TRANSFORMS
+    PNG_NO_READ_ANCILLARY_CHUNKS
+    PNG_NO_WRITE_ANCILLARY_CHUNKS
+
+PNG_MAX_UINT was replaced with PNG_UINT_31_MAX.  It has been
+deprecated since libpng-1.0.16 and libpng-1.2.6.
+
+The function
+    png_check_sig(sig, num)
+was replaced with
+    !png_sig_cmp(sig, 0, num)
+It has been deprecated since libpng-0.90.
+
+The function
+    png_set_gray_1_2_4_to_8()
+which also expands tRNS to alpha was replaced with
+    png_set_expand_gray_1_2_4_to_8()
+which does not. It has been deprecated since libpng-1.0.18 and 1.2.9.
+
+.SH IX.  (Omitted)
+
+
+.SH X. Detecting libpng
+
+The png_get_io_ptr() function has been present since libpng-0.88, has never
+changed, and is unaffected by conditional compilation macros.  It is the
+best choice for use in configure scripts for detecting the presence of any
+libpng version since 0.88.  In an autoconf "configure.in" you could use
+
+    AC_CHECK_LIB(png, png_get_io_ptr, ...
+
+.SH XI. Source code repository
+
+Since about February 2009, version 1.2.34, libpng has been under "git" source
+control.  The git repository was built from old libpng-x.y.z.tar.gz files
+going back to version 0.70.  You can access the git repository (read only)
+at
+
+    git://libpng.git.sourceforge.net/gitroot/libpng
+
+or you can browse it via "gitweb" at
+
+    http://libpng.git.sourceforge.net/git/gitweb.cgi?p=libpng
+
+Patches can be sent to glennrp at users.sourceforge.net or to
+png-mng-implement at lists.sourceforge.net or you can upload them to
+the libpng bug tracker at
+
+    http://libpng.sourceforge.net
+
+.SH XII. Coding style
+
+Our coding style is similar to the "Allman" style, with curly
+braces on separate lines:
+
+    if (condition)
+    {
+       action;
+    }
+
+    else if (another condition)
+    {
+       another action;
+    }
+
+The braces can be omitted from simple one-line actions:
+
+    if (condition)
+       return (0);
+
+We use 3-space indentation, except for continued statements which
+are usually indented the same as the first line of the statement
+plus four more spaces.
+
+For macro definitions we use 2-space indentation, always leaving the "#"
+in the first column.
+
+    #ifndef PNG_NO_FEATURE
+    #  ifndef PNG_FEATURE_SUPPORTED
+    #    define PNG_FEATURE_SUPPORTED
+    #  endif
+    #endif
+
+Comments appear with the leading "/*" at the same indentation as
+the statement that follows the comment:
+
+    /* Single-line comment */
+    statement;
+
+    /* Multiple-line
+     * comment
+     */
+    statement;
+
+Very short comments can be placed at the end of the statement
+to which they pertain:
+
+    statement;    /* comment */
+
+We don't use C++ style ("//") comments. We have, however,
+used them in the past in some now-abandoned MMX assembler
+code.
+
+Functions and their curly braces are not indented, and
+exported functions are marked with PNGAPI:
+
+ /* This is a public function that is visible to
+  * application programers. It does thus-and-so.
+  */
+ void PNGAPI
+ png_exported_function(png_ptr, png_info, foo)
+ {
+    body;
+ }
+
+The prototypes for all exported functions appear in png.h,
+above the comment that says
+
+    /* Maintainer: Put new public prototypes here ... */
+
+We mark all non-exported functions with "/* PRIVATE */"":
+
+ void /* PRIVATE */
+ png_non_exported_function(png_ptr, png_info, foo)
+ {
+    body;
+ }
+
+The prototypes for non-exported functions (except for those in
+pngtest) appear in
+the PNG_INTERNAL section of png.h
+above the comment that says
+
+  /* Maintainer: Put new private prototypes here ^ and in libpngpf.3 */
+
+The names of all exported functions and variables begin
+with  "png_", and all publicly visible C preprocessor
+macros begin with "PNG_".
+
+We put a space after each comma and after each semicolon
+in "for" statments, and we put spaces before and after each
+C binary operator and after "for" or "while".  We don't
+put a space between a typecast and the expression being
+cast, nor do we put one between a function name and the
+left parenthesis that follows it:
+
+    for (i = 2; i > 0; --i)
+       y[i] = a(x) + (int)b;
+
+We prefer #ifdef and #ifndef to #if defined() and if !defined()
+when there is only one macro being tested.
+
+We do not use the TAB character for indentation in the C sources.
+
+Lines do not exceed 80 characters.
+
+Other rules can be inferred by inspecting the libpng source.
+
+.SH XIII. Y2K Compliance in libpng
+
+June 26, 2010
+
+Since the PNG Development group is an ad-hoc body, we can't make
+an official declaration.
+
+This is your unofficial assurance that libpng from version 0.71 and
+upward through 1.2.44 are Y2K compliant.  It is my belief that earlier
+versions were also Y2K compliant.
+
+Libpng only has three year fields.  One is a 2-byte unsigned integer that
+will hold years up to 65535.  The other two hold the date in text
+format, and will hold years up to 9999.
+
+The integer is
+    "png_uint_16 year" in png_time_struct.
+
+The strings are
+    "png_charp time_buffer" in png_struct and
+    "near_time_buffer", which is a local character string in png.c.
+
+There are seven time-related functions:
+
+    png_convert_to_rfc_1123() in png.c
+      (formerly png_convert_to_rfc_1152() in error)
+    png_convert_from_struct_tm() in pngwrite.c, called
+      in pngwrite.c
+    png_convert_from_time_t() in pngwrite.c
+    png_get_tIME() in pngget.c
+    png_handle_tIME() in pngrutil.c, called in pngread.c
+    png_set_tIME() in pngset.c
+    png_write_tIME() in pngwutil.c, called in pngwrite.c
+
+All appear to handle dates properly in a Y2K environment.  The
+png_convert_from_time_t() function calls gmtime() to convert from system
+clock time, which returns (year - 1900), which we properly convert to
+the full 4-digit year.  There is a possibility that applications using
+libpng are not passing 4-digit years into the png_convert_to_rfc_1123()
+function, or that they are incorrectly passing only a 2-digit year
+instead of "year - 1900" into the png_convert_from_struct_tm() function,
+but this is not under our control.  The libpng documentation has always
+stated that it works with 4-digit years, and the APIs have been
+documented as such.
+
+The tIME chunk itself is also Y2K compliant.  It uses a 2-byte unsigned
+integer to hold the year, and can hold years as large as 65535.
+
+zlib, upon which libpng depends, is also Y2K compliant.  It contains
+no date-related code.

+.SH NOTE
+
+Note about libpng version numbers:
+
+Due to various miscommunications, unforeseen code incompatibilities
+and occasional factors outside the authors' control, version numbering
+on the library has not always been consistent and straightforward.
+The following table summarizes matters since version 0.89c, which was
+the first widely used release:
+
+ source             png.h  png.h  shared-lib

+Henceforth the source version will match the shared-library minor
+and patch numbers; the shared-library major version number will be
+used for changes in backward compatibility, as it is intended.  The
+PNG_PNGLIB_VER macro, which is not used within libpng but is available
+for applications, is an unsigned integer of the form xyyzz corresponding
+to the source version x.y.z (leading zeros in y and z).  Beta versions
+were given the previous public release number plus a letter, until
+version 1.0.6j; from then on they were given the upcoming public
+release number plus "betaNN" or "rcN".

+.TH PNG 5 "June 26, 2010"
+.SH NAME
+png \- Portable Network Graphics (PNG) format
+.SH DESCRIPTION
+PNG (Portable Network Graphics) is an extensible file format for the
+lossless, portable, well-compressed storage of raster images. PNG provides
+a patent-free replacement for GIF and can also replace many
+common uses of TIFF. Indexed-color, grayscale, and truecolor images are
+supported, plus an optional alpha channel. Sample depths range from
+1 to 16 bits.
+.br
+
+PNG is designed to work well in online viewing applications, such as the
+World Wide Web, so it is fully streamable with a progressive display
+option. PNG is robust, providing both full file integrity checking and
+fast, simple detection of common transmission errors. Also, PNG can store
+gamma and chromaticity data for improved color matching on heterogeneous
+platforms.

+/* From Andreas Dilger e-mail to png-implement, 26 March 1998:
+ *
+ *   In most cases, the "simple transparency" should be done prior to doing
+ *   gray-to-RGB, or you will have to test 3x as many bytes to check if a
+ *   pixel is transparent.  You would also need to make sure that the
+ *   transparency information is upgraded to RGB.
+ *
+ *   To summarize, the current flow is:
+ *   - Gray + simple transparency -> compare 1 or 2 gray bytes and composite
+ *                                   with background "in place" if transparent,
+ *                                   convert to RGB if necessary
+ *   - Gray + alpha -> composite with gray background and remove alpha bytes,
+ *                                   convert to RGB if necessary
+ *
+ *   To support RGB backgrounds for gray images we need:
+ *   - Gray + simple transparency -> convert to RGB + simple transparency,
+ *                                   compare 3 or 6 bytes and composite with
+ *                                   background "in place" if transparent
+ *                                   (3x compare/pixel compared to doing
+ *                                   composite with gray bkgrnd)
+ *   - Gray + alpha -> convert to RGB + alpha, composite with background and
+ *                                   remove alpha bytes (3x float
+ *                                   operations/pixel compared with composite
+ *                                   on gray background)
+ *
+ *  Greg's change will do this.  The reason it wasn't done before is for
+ *  performance, as this increases the per-pixel operations.  If we would check
+ *  in advance if the background was gray or RGB, and position the gray-to-RGB
+ *  transform appropriately, then it would save a lot of work/time.

+ * Copyright (c) 1998-2010 Glenn Randers-Pehrson
+ * (Version 0.96 Copyright (c) 1996, 1997 Andreas Dilger)

+ *
+ * This code is released under the libpng license.
+ * For conditions of distribution and use, see the disclaimer
+ * and license in png.h
+ *
+ * This program reads in a PNG image, writes it out again, and then
+ * compares the two files.  If the files are identical, this shows that
+ * the basic chunk handling, filtering, and (de)compression code is working
+ * properly.  It does not currently test all of the transforms, although
+ * it probably should.
+ *
+ * The program will report "FAIL" in certain legitimate cases:
+ * 1) when the compression level or filter selection method is changed.
+ * 2) when the maximum IDAT size (PNG_ZBUF_SIZE in pngconf.h) is not 8192.
+ * 3) unknown unsafe-to-copy ancillary chunks or unknown critical chunks
+ *    exist in the input file.
+ * 4) others not listed here...
+ * In these cases, it is best to check with another tool such as "pngcheck"
+ * to see what the differences between the two files are.
+ *
+ * If a filename is given on the command-line, then this file is used
+ * for the input, rather than the default "pngtest.png".  This allows
+ * testing a wide variety of files easily.  You can also test a number
+ * of files at once by typing "pngtest -m file1.png file2.png ..."

+ * io_ptr        - pointer to user supplied structure containing info about
+ *                 the output functions.  May be NULL.

+ *                 data to be written, and a 32-bit unsigned int that is
+ *                 the number of bytes to be written.  The new write
+ *                 function should call png_error(png_ptr, "Error msg")
+ *                 to exit and output any fatal error messages.  May be
+ *                 NULL, in which case libpng's default function will

+ * flush_data_fn - pointer to a new flush function that takes as its
+ *                 arguments a pointer to a png_struct.  After a call to
+ *                 the flush function, there should be no data in any buffers
+ *                 or pending transmission.  If the output method doesn't do
+ *                 any buffering of output, a function prototype must still be

+ *                 time, output_flush_fn will be ignored, although it must be

+ *                 libpng's default function will be used, if
+ *                 PNG_WRITE_FLUSH_SUPPORTED is defined.  This is not

+
+                Frequently Asked Questions about zlib
+
+
+If your question is not there, please check the zlib home page
+http://zlib.net/ which may have more recent information.
+The lastest zlib FAQ is at http://zlib.net/zlib_faq.html
+
+
+ 1. Is zlib Y2K-compliant?
+
+    Yes. zlib doesn't handle dates.
+
+ 2. Where can I get a Windows DLL version?
+
+    The zlib sources can be compiled without change to produce a DLL.  See the
+    file win32/DLL_FAQ.txt in the zlib distribution.  Pointers to the
+    precompiled DLL are found in the zlib web site at http://zlib.net/ .
+
+ 3. Where can I get a Visual Basic interface to zlib?
+
+    See
+        * http://marknelson.us/1997/01/01/zlib-engine/
+        * win32/DLL_FAQ.txt in the zlib distribution
+
+ 4. compress() returns Z_BUF_ERROR.
+
+    Make sure that before the call of compress(), the length of the compressed
+    buffer is equal to the available size of the compressed buffer and not
+    zero.  For Visual Basic, check that this parameter is passed by reference
+    ("as any"), not by value ("as long").
+
+ 5. deflate() or inflate() returns Z_BUF_ERROR.
+
+    Before making the call, make sure that avail_in and avail_out are not zero.
+    When setting the parameter flush equal to Z_FINISH, also make sure that
+    avail_out is big enough to allow processing all pending input.  Note that a
+    Z_BUF_ERROR is not fatal--another call to deflate() or inflate() can be
+    made with more input or output space.  A Z_BUF_ERROR may in fact be
+    unavoidable depending on how the functions are used, since it is not
+    possible to tell whether or not there is more output pending when
+    strm.avail_out returns with zero.  See http://zlib.net/zlib_how.html for a
+    heavily annotated example.
+
+ 6. Where's the zlib documentation (man pages, etc.)?
+
+    It's in zlib.h .  Examples of zlib usage are in the files example.c and
+    minigzip.c, with more in examples/ .
+
+ 7. Why don't you use GNU autoconf or libtool or ...?
+
+    Because we would like to keep zlib as a very small and simple package.
+    zlib is rather portable and doesn't need much configuration.
+
+ 8. I found a bug in zlib.
+
+    Most of the time, such problems are due to an incorrect usage of zlib.
+    Please try to reproduce the problem with a small program and send the
+    corresponding source to us at zlib@gzip.org .  Do not send multi-megabyte
+    data files without prior agreement.
+
+ 9. Why do I get "undefined reference to gzputc"?
+
+    If "make test" produces something like
+
+       example.o(.text+0x154): undefined reference to `gzputc'
+
+    check that you don't have old files libz.* in /usr/lib, /usr/local/lib or
+    /usr/X11R6/lib. Remove any old versions, then do "make install".
+
+10. I need a Delphi interface to zlib.
+
+    See the contrib/delphi directory in the zlib distribution.
+
+11. Can zlib handle .zip archives?
+
+    Not by itself, no.  See the directory contrib/minizip in the zlib
+    distribution.
+
+12. Can zlib handle .Z files?
+
+    No, sorry.  You have to spawn an uncompress or gunzip subprocess, or adapt
+    the code of uncompress on your own.
+
+13. How can I make a Unix shared library?
+
+    make clean
+    ./configure -s
+    make
+
+14. How do I install a shared zlib library on Unix?
+
+    After the above, then:
+
+    make install
+
+    However, many flavors of Unix come with a shared zlib already installed.
+    Before going to the trouble of compiling a shared version of zlib and
+    trying to install it, you may want to check if it's already there!  If you
+    can #include <zlib.h>, it's there.  The -lz option will probably link to
+    it.  You can check the version at the top of zlib.h or with the
+    ZLIB_VERSION symbol defined in zlib.h .
+
+15. I have a question about OttoPDF.
+
+    We are not the authors of OttoPDF. The real author is on the OttoPDF web
+    site: Joel Hainley, jhainley@myndkryme.com.
+
+16. Can zlib decode Flate data in an Adobe PDF file?
+
+    Yes. See http://www.pdflib.com/ . To modify PDF forms, see
+    http://sourceforge.net/projects/acroformtool/ .
+
+17. Why am I getting this "register_frame_info not found" error on Solaris?
+
+    After installing zlib 1.1.4 on Solaris 2.6, running applications using zlib
+    generates an error such as:
+
+        ld.so.1: rpm: fatal: relocation error: file /usr/local/lib/libz.so:
+        symbol __register_frame_info: referenced symbol not found
+
+    The symbol __register_frame_info is not part of zlib, it is generated by
+    the C compiler (cc or gcc).  You must recompile applications using zlib
+    which have this problem.  This problem is specific to Solaris.  See
+    http://www.sunfreeware.com for Solaris versions of zlib and applications
+    using zlib.
+
+18. Why does gzip give an error on a file I make with compress/deflate?
+
+    The compress and deflate functions produce data in the zlib format, which
+    is different and incompatible with the gzip format.  The gz* functions in
+    zlib on the other hand use the gzip format.  Both the zlib and gzip formats
+    use the same compressed data format internally, but have different headers
+    and trailers around the compressed data.
+
+19. Ok, so why are there two different formats?
+
+    The gzip format was designed to retain the directory information about a
+    single file, such as the name and last modification date.  The zlib format
+    on the other hand was designed for in-memory and communication channel
+    applications, and has a much more compact header and trailer and uses a
+    faster integrity check than gzip.
+
+20. Well that's nice, but how do I make a gzip file in memory?
+
+    You can request that deflate write the gzip format instead of the zlib
+    format using deflateInit2().  You can also request that inflate decode the
+    gzip format using inflateInit2().  Read zlib.h for more details.
+
+21. Is zlib thread-safe?
+
+    Yes.  However any library routines that zlib uses and any application-
+    provided memory allocation routines must also be thread-safe.  zlib's gz*
+    functions use stdio library routines, and most of zlib's functions use the
+    library memory allocation routines by default.  zlib's *Init* functions
+    allow for the application to provide custom memory allocation routines.
+
+    Of course, you should only operate on any given zlib or gzip stream from a
+    single thread at a time.
+
+22. Can I use zlib in my commercial application?
+
+    Yes.  Please read the license in zlib.h.
+
+23. Is zlib under the GNU license?
+
+    No.  Please read the license in zlib.h.
+
+24. The license says that altered source versions must be "plainly marked". So
+    what exactly do I need to do to meet that requirement?
+
+    You need to change the ZLIB_VERSION and ZLIB_VERNUM #defines in zlib.h.  In
+    particular, the final version number needs to be changed to "f", and an
+    identification string should be appended to ZLIB_VERSION.  Version numbers
+    x.x.x.f are reserved for modifications to zlib by others than the zlib
+    maintainers.  For example, if the version of the base zlib you are altering
+    is "1.2.3.4", then in zlib.h you should change ZLIB_VERNUM to 0x123f, and
+    ZLIB_VERSION to something like "1.2.3.f-zachary-mods-v3".  You can also
+    update the version strings in deflate.c and inftrees.c.
+
+    For altered source distributions, you should also note the origin and
+    nature of the changes in zlib.h, as well as in ChangeLog and README, along
+    with the dates of the alterations.  The origin should include at least your
+    name (or your company's name), and an email address to contact for help or
+    issues with the library.
+
+    Note that distributing a compiled zlib library along with zlib.h and
+    zconf.h is also a source distribution, and so you should change
+    ZLIB_VERSION and ZLIB_VERNUM and note the origin and nature of the changes
+    in zlib.h as you would for a full source distribution.
+
+25. Will zlib work on a big-endian or little-endian architecture, and can I
+    exchange compressed data between them?
+
+    Yes and yes.
+
+26. Will zlib work on a 64-bit machine?
+
+    Yes.  It has been tested on 64-bit machines, and has no dependence on any
+    data types being limited to 32-bits in length.  If you have any
+    difficulties, please provide a complete problem report to zlib@gzip.org
+
+27. Will zlib decompress data from the PKWare Data Compression Library?
+
+    No.  The PKWare DCL uses a completely different compressed data format than
+    does PKZIP and zlib.  However, you can look in zlib's contrib/blast
+    directory for a possible solution to your problem.
+
+28. Can I access data randomly in a compressed stream?
+
+    No, not without some preparation.  If when compressing you periodically use
+    Z_FULL_FLUSH, carefully write all the pending data at those points, and
+    keep an index of those locations, then you can start decompression at those
+    points.  You have to be careful to not use Z_FULL_FLUSH too often, since it
+    can significantly degrade compression.  Alternatively, you can scan a
+    deflate stream once to generate an index, and then use that index for
+    random access.  See examples/zran.c .
+
+29. Does zlib work on MVS, OS/390, CICS, etc.?
+
+    It has in the past, but we have not heard of any recent evidence.  There
+    were working ports of zlib 1.1.4 to MVS, but those links no longer work.
+    If you know of recent, successful applications of zlib on these operating
+    systems, please let us know.  Thanks.
+
+30. Is there some simpler, easier to read version of inflate I can look at to
+    understand the deflate format?
+
+    First off, you should read RFC 1951.  Second, yes.  Look in zlib's
+    contrib/puff directory.
+
+31. Does zlib infringe on any patents?
+
+    As far as we know, no.  In fact, that was originally the whole point behind
+    zlib.  Look here for some more information:
+
+    http://www.gzip.org/#faq11
+
+32. Can zlib work with greater than 4 GB of data?
+
+    Yes.  inflate() and deflate() will process any amount of data correctly.
+    Each call of inflate() or deflate() is limited to input and output chunks
+    of the maximum value that can be stored in the compiler's "unsigned int"
+    type, but there is no limit to the number of chunks.  Note however that the
+    strm.total_in and strm_total_out counters may be limited to 4 GB.  These
+    counters are provided as a convenience and are not used internally by
+    inflate() or deflate().  The application can easily set up its own counters
+    updated after each call of inflate() or deflate() to count beyond 4 GB.
+    compress() and uncompress() may be limited to 4 GB, since they operate in a
+    single call.  gzseek() and gztell() may be limited to 4 GB depending on how
+    zlib is compiled.  See the zlibCompileFlags() function in zlib.h.
+
+    The word "may" appears several times above since there is a 4 GB limit only
+    if the compiler's "long" type is 32 bits.  If the compiler's "long" type is
+    64 bits, then the limit is 16 exabytes.
+
+33. Does zlib have any security vulnerabilities?
+
+    The only one that we are aware of is potentially in gzprintf().  If zlib is
+    compiled to use sprintf() or vsprintf(), then there is no protection
+    against a buffer overflow of an 8K string space (or other value as set by
+    gzbuffer()), other than the caller of gzprintf() assuring that the output
+    will not exceed 8K.  On the other hand, if zlib is compiled to use
+    snprintf() or vsnprintf(), which should normally be the case, then there is
+    no vulnerability.  The ./configure script will display warnings if an
+    insecure variation of sprintf() will be used by gzprintf().  Also the
+    zlibCompileFlags() function will return information on what variant of
+    sprintf() is used by gzprintf().
+
+    If you don't have snprintf() or vsnprintf() and would like one, you can
+    find a portable implementation here:
+
+        http://www.ijs.si/software/snprintf/
+
+    Note that you should be using the most recent version of zlib.  Versions
+    1.1.3 and before were subject to a double-free vulnerability, and versions
+    1.2.1 and 1.2.2 were subject to an access exception when decompressing
+    invalid compressed data.
+
+34. Is there a Java version of zlib?
+
+    Probably what you want is to use zlib in Java. zlib is already included
+    as part of the Java SDK in the java.util.zip package. If you really want
+    a version of zlib written in the Java language, look on the zlib home
+    page for links: http://zlib.net/ .
+
+35. I get this or that compiler or source-code scanner warning when I crank it
+    up to maximally-pedantic. Can't you guys write proper code?
+
+    Many years ago, we gave up attempting to avoid warnings on every compiler
+    in the universe.  It just got to be a waste of time, and some compilers
+    were downright silly as well as contradicted each other.  So now, we simply
+    make sure that the code always works.
+
+36. Valgrind (or some similar memory access checker) says that deflate is
+    performing a conditional jump that depends on an uninitialized value.
+    Isn't that a bug?
+
+    No.  That is intentional for performance reasons, and the output of deflate
+    is not affected.  This only started showing up recently since zlib 1.2.x
+    uses malloc() by default for allocations, whereas earlier versions used
+    calloc(), which zeros out the allocated memory.  Even though the code was
+    correct, versions 1.2.4 and later was changed to not stimulate these
+    checkers.
+
+37. Will zlib read the (insert any ancient or arcane format here) compressed
+    data format?
+
+    Probably not. Look in the comp.compression FAQ for pointers to various
+    formats and associated software.
+
+38. How can I encrypt/decrypt zip files with zlib?
+
+    zlib doesn't support encryption.  The original PKZIP encryption is very
+    weak and can be broken with freely available programs.  To get strong
+    encryption, use GnuPG, http://www.gnupg.org/ , which already includes zlib
+    compression.  For PKZIP compatible "encryption", look at
+    http://www.info-zip.org/
+
+39. What's the difference between the "gzip" and "deflate" HTTP 1.1 encodings?
+
+    "gzip" is the gzip format, and "deflate" is the zlib format.  They should
+    probably have called the second one "zlib" instead to avoid confusion with
+    the raw deflate compressed data format.  While the HTTP 1.1 RFC 2616
+    correctly points to the zlib specification in RFC 1950 for the "deflate"
+    transfer encoding, there have been reports of servers and browsers that
+    incorrectly produce or expect raw deflate data per the deflate
+    specficiation in RFC 1951, most notably Microsoft.  So even though the
+    "deflate" transfer encoding using the zlib format would be the more
+    efficient approach (and in fact exactly what the zlib format was designed
+    for), using the "gzip" transfer encoding is probably more reliable due to
+    an unfortunate choice of name on the part of the HTTP 1.1 authors.
+
+    Bottom line: use the gzip format for HTTP 1.1 encoding.
+
+40. Does zlib support the new "Deflate64" format introduced by PKWare?
+
+    No.  PKWare has apparently decided to keep that format proprietary, since
+    they have not documented it as they have previous compression formats.  In
+    any case, the compression improvements are so modest compared to other more
+    modern approaches, that it's not worth the effort to implement.
+
+41. I'm having a problem with the zip functions in zlib, can you help?
+
+    There are no zip functions in zlib.  You are probably using minizip by
+    Giles Vollant, which is found in the contrib directory of zlib.  It is not
+    part of zlib.  In fact none of the stuff in contrib is part of zlib.  The
+    files in there are not supported by the zlib authors.  You need to contact
+    the authors of the respective contribution for help.
+
+42. The match.asm code in contrib is under the GNU General Public License.
+    Since it's part of zlib, doesn't that mean that all of zlib falls under the
+    GNU GPL?
+
+    No.  The files in contrib are not part of zlib.  They were contributed by
+    other authors and are provided as a convenience to the user within the zlib
+    distribution.  Each item in contrib has its own license.
+
+43. Is zlib subject to export controls?  What is its ECCN?
+
+    zlib is not subject to export controls, and so is classified as EAR99.
+
+44. Can you please sign these lengthy legal documents and fax them back to us
+    so that we can use your software in our product?
+
+    No. Go away. Shoo.

+ZLIB DATA COMPRESSION LIBRARY
+
+zlib 1.2.5 is a general purpose data compression library.  All the code is
+thread safe.  The data format used by the zlib library is described by RFCs
+(Request for Comments) 1950 to 1952 in the files
+http://www.ietf.org/rfc/rfc1950.txt (zlib format), rfc1951.txt (deflate format)
+and rfc1952.txt (gzip format).
+
+All functions of the compression library are documented in the file zlib.h
+(volunteer to write man pages welcome, contact zlib@gzip.org).  A usage example
+of the library is given in the file example.c which also tests that the library
+is working correctly.  Another example is given in the file minigzip.c.  The
+compression library itself is composed of all source files except example.c and
+minigzip.c.
+
+To compile all files and run the test program, follow the instructions given at
+the top of Makefile.in.  In short "./configure; make test", and if that goes
+well, "make install" should work for most flavors of Unix.  For Windows, use one
+of the special makefiles in win32/ or contrib/vstudio/ .  For VMS, use
+make_vms.com.
+
+Questions about zlib should be sent to <zlib@gzip.org>, or to Gilles Vollant
+<info@winimage.com> for the Windows DLL version.  The zlib home page is
+http://zlib.net/ .  Before reporting a problem, please check this site to
+verify that you have the latest version of zlib; otherwise get the latest
+version and check whether the problem still exists or not.
+
+PLEASE read the zlib FAQ http://zlib.net/zlib_faq.html before asking for help.
+
+Mark Nelson <markn@ieee.org> wrote an article about zlib for the Jan.  1997
+issue of Dr.  Dobb's Journal; a copy of the article is available at
+http://marknelson.us/1997/01/01/zlib-engine/ .
+
+The changes made in version 1.2.5 are documented in the file ChangeLog.
+
+Unsupported third party contributions are provided in directory contrib/ .
+
+zlib is available in Java using the java.util.zip package, documented at
+http://java.sun.com/developer/technicalArticles/Programming/compression/ .
+
+A Perl interface to zlib written by Paul Marquess <pmqs@cpan.org> is available
+at CPAN (Comprehensive Perl Archive Network) sites, including
+http://search.cpan.org/~pmqs/IO-Compress-Zlib/ .
+
+A Python interface to zlib written by A.M. Kuchling <amk@amk.ca> is
+available in Python 1.5 and later versions, see
+http://www.python.org/doc/lib/module-zlib.html .
+
+zlib is built into tcl: http://wiki.tcl.tk/4610 .
+
+An experimental package to read and write files in .zip format, written on top
+of zlib by Gilles Vollant <info@winimage.com>, is available in the
+contrib/minizip directory of zlib.
+
+
+Notes for some targets:
+
+- For Windows DLL versions, please see win32/DLL_FAQ.txt
+
+- For 64-bit Irix, deflate.c must be compiled without any optimization. With
+  -O, one libpng test fails. The test works in 32 bit mode (with the -n32
+  compiler flag). The compiler bug has been reported to SGI.
+
+- zlib doesn't work with gcc 2.6.3 on a DEC 3000/300LX under OSF/1 2.1 it works
+  when compiled with cc.
+
+- On Digital Unix 4.0D (formely OSF/1) on AlphaServer, the cc option -std1 is
+  necessary to get gzprintf working correctly. This is done by configure.
+
+- zlib doesn't work on HP-UX 9.05 with some versions of /bin/cc. It works with
+  other compilers. Use "make test" to check your compiler.
+
+- gzdopen is not supported on RISCOS or BEOS.
+
+- For PalmOs, see http://palmzlib.sourceforge.net/

+1. Compression algorithm (deflate)
+
+The deflation algorithm used by gzip (also zip and zlib) is a variation of
+LZ77 (Lempel-Ziv 1977, see reference below). It finds duplicated strings in
+the input data.  The second occurrence of a string is replaced by a
+pointer to the previous string, in the form of a pair (distance,
+length).  Distances are limited to 32K bytes, and lengths are limited
+to 258 bytes. When a string does not occur anywhere in the previous
+32K bytes, it is emitted as a sequence of literal bytes.  (In this
+description, `string' must be taken as an arbitrary sequence of bytes,
+and is not restricted to printable characters.)
+
+Literals or match lengths are compressed with one Huffman tree, and
+match distances are compressed with another tree. The trees are stored
+in a compact form at the start of each block. The blocks can have any
+size (except that the compressed data for one block must fit in
+available memory). A block is terminated when deflate() determines that
+it would be useful to start another block with fresh trees. (This is
+somewhat similar to the behavior of LZW-based _compress_.)
+
+Duplicated strings are found using a hash table. All input strings of
+length 3 are inserted in the hash table. A hash index is computed for
+the next 3 bytes. If the hash chain for this index is not empty, all
+strings in the chain are compared with the current input string, and
+the longest match is selected.
+
+The hash chains are searched starting with the most recent strings, to
+favor small distances and thus take advantage of the Huffman encoding.
+The hash chains are singly linked. There are no deletions from the
+hash chains, the algorithm simply discards matches that are too old.
+
+To avoid a worst-case situation, very long hash chains are arbitrarily
+truncated at a certain length, determined by a runtime option (level
+parameter of deflateInit). So deflate() does not always find the longest
+possible match but generally finds a match which is long enough.
+
+deflate() also defers the selection of matches with a lazy evaluation
+mechanism. After a match of length N has been found, deflate() searches for
+a longer match at the next input byte. If a longer match is found, the
+previous match is truncated to a length of one (thus producing a single
+literal byte) and the process of lazy evaluation begins again. Otherwise,
+the original match is kept, and the next match search is attempted only N
+steps later.
+
+The lazy match evaluation is also subject to a runtime parameter. If
+the current match is long enough, deflate() reduces the search for a longer
+match, thus speeding up the whole process. If compression ratio is more
+important than speed, deflate() attempts a complete second search even if
+the first match is already long enough.
+
+The lazy match evaluation is not performed for the fastest compression
+modes (level parameter 1 to 3). For these fast modes, new strings
+are inserted in the hash table only when no match was found, or
+when the match is not too long. This degrades the compression ratio
+but saves time since there are both fewer insertions and fewer searches.
+
+
+2. Decompression algorithm (inflate)
+
+2.1 Introduction
+
+The key question is how to represent a Huffman code (or any prefix code) so
+that you can decode fast.  The most important characteristic is that shorter
+codes are much more common than longer codes, so pay attention to decoding the
+short codes fast, and let the long codes take longer to decode.
+
+inflate() sets up a first level table that covers some number of bits of
+input less than the length of longest code.  It gets that many bits from the
+stream, and looks it up in the table.  The table will tell if the next
+code is that many bits or less and how many, and if it is, it will tell
+the value, else it will point to the next level table for which inflate()
+grabs more bits and tries to decode a longer code.
+
+How many bits to make the first lookup is a tradeoff between the time it
+takes to decode and the time it takes to build the table.  If building the
+table took no time (and if you had infinite memory), then there would only
+be a first level table to cover all the way to the longest code.  However,
+building the table ends up taking a lot longer for more bits since short
+codes are replicated many times in such a table.  What inflate() does is
+simply to make the number of bits in the first table a variable, and  then
+to set that variable for the maximum speed.
+
+For inflate, which has 286 possible codes for the literal/length tree, the size
+of the first table is nine bits.  Also the distance trees have 30 possible
+values, and the size of the first table is six bits.  Note that for each of
+those cases, the table ended up one bit longer than the ``average'' code
+length, i.e. the code length of an approximately flat code which would be a
+little more than eight bits for 286 symbols and a little less than five bits
+for 30 symbols.
+
+
+2.2 More details on the inflate table lookup
+
+Ok, you want to know what this cleverly obfuscated inflate tree actually
+looks like.  You are correct that it's not a Huffman tree.  It is simply a
+lookup table for the first, let's say, nine bits of a Huffman symbol.  The
+symbol could be as short as one bit or as long as 15 bits.  If a particular
+symbol is shorter than nine bits, then that symbol's translation is duplicated
+in all those entries that start with that symbol's bits.  For example, if the
+symbol is four bits, then it's duplicated 32 times in a nine-bit table.  If a
+symbol is nine bits long, it appears in the table once.
+
+If the symbol is longer than nine bits, then that entry in the table points
+to another similar table for the remaining bits.  Again, there are duplicated
+entries as needed.  The idea is that most of the time the symbol will be short
+and there will only be one table look up.  (That's whole idea behind data
+compression in the first place.)  For the less frequent long symbols, there
+will be two lookups.  If you had a compression method with really long
+symbols, you could have as many levels of lookups as is efficient.  For
+inflate, two is enough.
+
+So a table entry either points to another table (in which case nine bits in
+the above example are gobbled), or it contains the translation for the symbol
+and the number of bits to gobble.  Then you start again with the next
+ungobbled bit.
+
+You may wonder: why not just have one lookup table for how ever many bits the
+longest symbol is?  The reason is that if you do that, you end up spending
+more time filling in duplicate symbol entries than you do actually decoding.
+At least for deflate's output that generates new trees every several 10's of
+kbytes.  You can imagine that filling in a 2^15 entry table for a 15-bit code
+would take too long if you're only decoding several thousand symbols.  At the
+other extreme, you could make a new table for every bit in the code.  In fact,
+that's essentially a Huffman tree.  But then you spend two much time
+traversing the tree while decoding, even for short symbols.
+
+So the number of bits for the first lookup table is a trade of the time to
+fill out the table vs. the time spent looking at the second level and above of
+the table.
+
+Here is an example, scaled down:
+
+The code being decoded, with 10 symbols, from 1 to 6 bits long:
+
+A: 0
+B: 10
+C: 1100
+D: 11010
+E: 11011
+F: 11100
+G: 11101
+H: 11110
+I: 111110
+J: 111111
+
+Let's make the first table three bits long (eight entries):
+
+000: A,1
+001: A,1
+010: A,1
+011: A,1
+100: B,2
+101: B,2
+110: -> table X (gobble 3 bits)
+111: -> table Y (gobble 3 bits)
+
+Each entry is what the bits decode as and how many bits that is, i.e. how
+many bits to gobble.  Or the entry points to another table, with the number of
+bits to gobble implicit in the size of the table.
+
+Table X is two bits long since the longest code starting with 110 is five bits
+long:
+
+00: C,1
+01: C,1
+10: D,2
+11: E,2
+
+Table Y is three bits long since the longest code starting with 111 is six
+bits long:
+
+000: F,2
+001: F,2
+010: G,2
+011: G,2
+100: H,2
+101: H,2
+110: I,3
+111: J,3
+
+So what we have here are three tables with a total of 20 entries that had to
+be constructed.  That's compared to 64 entries for a single table.  Or
+compared to 16 entries for a Huffman tree (six two entry tables and one four
+entry table).  Assuming that the code ideally represents the probability of
+the symbols, it takes on the average 1.25 lookups per symbol.  That's compared
+to one lookup for the single table, or 1.66 lookups per symbol for the
+Huffman tree.
+
+There, I think that gives you a picture of what's going on.  For inflate, the
+meaning of a particular symbol is often more than just a letter.  It can be a

+  Generate tables for a byte-wise 32-bit CRC calculation on the polynomial:
+  x^32+x^26+x^23+x^22+x^16+x^12+x^11+x^10+x^8+x^7+x^5+x^4+x^2+x+1.
+
+  Polynomials over GF(2) are represented in binary, one bit per coefficient,
+  with the lowest powers in the most significant bit.  Then adding polynomials
+  is just exclusive-or, and multiplying a polynomial by x is a right shift by
+  one.  If we call the above polynomial p, and represent a byte as the
+  polynomial q, also with the lowest power in the most significant bit (so the
+  byte 0xb1 is the polynomial x^7+x^3+x+1), then the CRC is (q*x^32) mod p,
+  where a mod b means the remainder after dividing a by b.
+
+  This calculation is done using the shift-register method of multiplying and
+  taking the remainder.  The register is initialized to zero, and for each
+  incoming bit, x^32 is added mod p to the register if the bit is a one (where
+  x^32 mod p is p+x^32 = x^26+...+1), and the register is multiplied mod p by
+  x (which is shifting right by one and adding x^32 mod p if the bit shifted
+  out is a one).  We start with the highest power (least significant bit) of
+  q and repeat for all eight bits of q.
+
+  The first table is simply the CRC of all possible eight bit values.  This is
+  all the information needed to generate CRCs on data a byte at a time for all
+  combinations of CRC register values and incoming bytes.  The remaining tables
+  allow for word-at-a-time CRC calculation for both big-endian and little-
+  endian machines, where a word is four bytes.

+/*
+ *  ALGORITHM
+ *
+ *      The "deflation" process depends on being able to identify portions
+ *      of the input text which are identical to earlier input (within a
+ *      sliding window trailing behind the input currently being processed).
+ *
+ *      The most straightforward technique turns out to be the fastest for
+ *      most input files: try all possible matches and select the longest.
+ *      The key feature of this algorithm is that insertions into the string
+ *      dictionary are very simple and thus fast, and deletions are avoided
+ *      completely. Insertions are performed at each input character, whereas
+ *      string matches are performed only when the previous match ends. So it
+ *      is preferable to spend more time in matches to allow very fast string
+ *      insertions and avoid deletions. The matching algorithm for small
+ *      strings is inspired from that of Rabin & Karp. A brute force approach
+ *      is used to find longer strings when a small match has been found.
+ *      A similar algorithm is used in comic (by Jan-Mark Wams) and freeze
+ *      (by Leonid Broukhis).
+ *         A previous version of this file used a more sophisticated algorithm
+ *      (by Fiala and Greene) which is guaranteed to run in linear amortized
+ *      time, but has a larger average cost, uses more memory and is patented.
+ *      However the F&G algorithm may be faster for some highly redundant
+ *      files if the parameter max_chain_length (described below) is too large.
+ *
+ *  ACKNOWLEDGEMENTS
+ *
+ *      The idea of lazy evaluation of matches is due to Jan-Mark Wams, and
+ *      I found it in 'freeze' written by Leonid Broukhis.
+ *      Thanks to many people for bug reports and testing.

+   filled the window with output, or when it completes with data in the
+   window, it calls out() to write out the data.  The application must not

+
+   in() and out() are called with a descriptor parameter provided in the

+   information required to do the read or write, as well as accumulated
+   information on the input and output such as totals and check values.
+
+   in() should return zero on failure.  out() should return non-zero on
+   failure.  If either in() or out() fails, than inflateBack() returns a
+   Z_BUF_ERROR.  strm->next_in can be checked for Z_NULL to see whether it
+   was in() or out() that caused in the error.  Otherwise,  inflateBack()
+   returns Z_STREAM_END on success, Z_DATA_ERROR for an deflate format
+   error, or Z_MEM_ERROR if it could not allocate memory for the state.

+   Decode literal, length, and distance codes and write out the resulting
+   literal and match bytes until either not enough input or output is
+   available, an end-of-block is encountered, or a data error is encountered.
+   When large enough input and output buffers are supplied to inflate(), for
+   example, a 16K input buffer and a 64K output buffer, more than 95% of the
+   inflate execution time is spent in this routine.
+
+   Entry assumptions:
+
+        state->mode == LEN
+        strm->avail_in >= 6
+        strm->avail_out >= 258
+        start >= strm->avail_out
+        state->bits < 8
+
+   On return, state->mode is one of:
+
+        LEN -- ran out of enough output space or enough available input
+        TYPE -- reached end of block code, inflate() to interpret next block
+        BAD -- error in block data
+
+   Notes:
+
+    - The maximum input bits used by a length/distance pair is 15 bits for the
+      length code, 5 bits for the length extra, 15 bits for the distance code,
+      and 13 bits for the distance extra.  This totals 48 bits, or six bytes.
+      Therefore if strm->avail_in >= 6, then there is enough input to avoid
+      checking for available input while decoding.
+
+    - The maximum bytes that a single length/distance pair can output is 258
+      bytes, which is the maximum length that can be coded.  inflate_fast()
+      requires strm->avail_out >= 258 for each loop to avoid checking for
+      output space.

+/* inflate.c -- zlib decompression
+ * Copyright (C) 1995-2010 Mark Adler
+ * For conditions of distribution and use, see copyright notice in zlib.h
+ */
+
+/*
+ * Change history:
+ *
+ * 1.2.beta0    24 Nov 2002
+ * - First version -- complete rewrite of inflate to simplify code, avoid
+ *   creation of window when not needed, minimize use of window when it is
+ *   needed, make inffast.c even faster, implement gzip decoding, and to
+ *   improve code readability and style over the previous zlib inflate code
+ *
+ * 1.2.beta1    25 Nov 2002
+ * - Use pointers for available input and output checking in inffast.c
+ * - Remove input and output counters in inffast.c
+ * - Change inffast.c entry and loop from avail_in >= 7 to >= 6
+ * - Remove unnecessary second byte pull from length extra in inffast.c
+ * - Unroll direct copy to three copies per loop in inffast.c
+ *
+ * 1.2.beta2    4 Dec 2002
+ * - Change external routine names to reduce potential conflicts
+ * - Correct filename to inffixed.h for fixed tables in inflate.c
+ * - Make hbuf[] unsigned char to match parameter type in inflate.c
+ * - Change strm->next_out[-state->offset] to *(strm->next_out - state->offset)
+ *   to avoid negation problem on Alphas (64 bit) in inflate.c
+ *
+ * 1.2.beta3    22 Dec 2002
+ * - Add comments on state->bits assertion in inffast.c
+ * - Add comments on op field in inftrees.h
+ * - Fix bug in reuse of allocated window after inflateReset()
+ * - Remove bit fields--back to byte structure for speed
+ * - Remove distance extra == 0 check in inflate_fast()--only helps for lengths
+ * - Change post-increments to pre-increments in inflate_fast(), PPC biased?
+ * - Add compile time option, POSTINC, to use post-increments instead (Intel?)
+ * - Make MATCH copy in inflate() much faster for when inflate_fast() not used
+ * - Use local copies of stream next and avail values, as well as local bit
+ *   buffer and bit count in inflate()--for speed when inflate_fast() not used
+ *
+ * 1.2.beta4    1 Jan 2003
+ * - Split ptr - 257 statements in inflate_table() to avoid compiler warnings
+ * - Move a comment on output buffer sizes from inffast.c to inflate.c
+ * - Add comments in inffast.c to introduce the inflate_fast() routine
+ * - Rearrange window copies in inflate_fast() for speed and simplification
+ * - Unroll last copy for window match in inflate_fast()
+ * - Use local copies of window variables in inflate_fast() for speed
+ * - Pull out common wnext == 0 case for speed in inflate_fast()
+ * - Make op and len in inflate_fast() unsigned for consistency
+ * - Add FAR to lcode and dcode declarations in inflate_fast()
+ * - Simplified bad distance check in inflate_fast()
+ * - Added inflateBackInit(), inflateBack(), and inflateBackEnd() in new
+ *   source file infback.c to provide a call-back interface to inflate for
+ *   programs like gzip and unzip -- uses window as output buffer to avoid
+ *   window copying
+ *
+ * 1.2.beta5    1 Jan 2003
+ * - Improved inflateBack() interface to allow the caller to provide initial
+ *   input in strm.
+ * - Fixed stored blocks bug in inflateBack()
+ *
+ * 1.2.beta6    4 Jan 2003
+ * - Added comments in inffast.c on effectiveness of POSTINC
+ * - Typecasting all around to reduce compiler warnings
+ * - Changed loops from while (1) or do {} while (1) to for (;;), again to
+ *   make compilers happy
+ * - Changed type of window in inflateBackInit() to unsigned char *
+ *
+ * 1.2.beta7    27 Jan 2003
+ * - Changed many types to unsigned or unsigned short to avoid warnings
+ * - Added inflateCopy() function
+ *
+ * 1.2.0        9 Mar 2003
+ * - Changed inflateBack() interface to provide separate opaque descriptors
+ *   for the in() and out() functions
+ * - Changed inflateBack() argument and in_func typedef to swap the length
+ *   and buffer address return values for the input function
+ * - Check next_in and next_out for Z_NULL on entry to inflate()
+ *
+ * The history for versions after 1.2.0 are in ChangeLog in zlib distribution.

+   inflate() uses a state machine to process as much input data and generate as
+   much output data as possible before returning.  The state machine is
+   structured roughly as follows:
+
+    for (;;) switch (state) {
+    ...
+    case STATEn:
+        if (not enough input data or output space to make progress)
+            return;
+        ... make progress ...
+        state = STATEm;
+        break;
+    ...
+    }
+
+   so when inflate() is called again, the same case is attempted again, and
+   if the appropriate resources are provided, the machine proceeds to the
+   next state.  The NEEDBITS() macro is usually the way the state evaluates
+   whether it can proceed or should return.  NEEDBITS() does the return if
+   the requested bits are not available.  The typical use of the BITS macros
+   is:
+
+        NEEDBITS(n);
+        ... do something with BITS(n) ...
+        DROPBITS(n);
+
+   where NEEDBITS(n) either returns from inflate() if there isn't enough
+   input left to load n bits into the accumulator, or it continues.  BITS(n)
+   gives the low n bits in the accumulator.  When done, DROPBITS(n) drops
+   the low n bits off the accumulator.  INITBITS() clears the accumulator
+   and sets the number of available bits to zero.  BYTEBITS() discards just
+   enough bits to put the accumulator on a byte boundary.  After BYTEBITS()
+   and a NEEDBITS(8), then BITS(8) would return the next byte in the stream.
+
+   NEEDBITS(n) uses PULLBYTE() to get an available byte of input, or to return
+   if there is no input available.  The decoding of variable length codes uses
+   PULLBYTE() directly in order to pull just enough bytes to decode the next
+   code, and no more.
+
+   Some states loop until they get enough input, making sure that enough
+   state information is maintained to continue the loop where it left off
+   if NEEDBITS() returns in the loop.  For example, want, need, and keep
+   would all have to actually be part of the saved state in case NEEDBITS()
+   returns:
+
+    case STATEw:
+        while (want < need) {
+            NEEDBITS(n);
+            keep[want++] = BITS(n);
+            DROPBITS(n);
+        }
+        state = STATEx;
+    case STATEx:
+
+   As shown above, if the next state is also the next case, then the break
+   is omitted.
+
+   A state may also return if there is not enough output space available to
+   complete that state.  Those states are copying stored data, writing a
+   literal byte, and copying a matching string.
+
+   When returning, a "goto inf_leave" is used to update the total counters,
+   update the check value, and determine whether any progress has been made
+   during that inflate() call in order to return the proper return code.
+   Progress is defined as a change in either strm->avail_in or strm->avail_out.
+   When there is a window, goto inf_leave will update the window with the last
+   output written.  If a goto inf_leave occurs in the middle of decompression
+   and there is no window currently, goto inf_leave will create one and copy
+   output to the window for the next call of inflate().
+
+   In this implementation, the flush parameter of inflate() only affects the
+   return code (per zlib.h).  inflate() always writes as much as possible to
+   strm->next_out, given the space available and the provided input--the effect
+   documented in zlib.h of Z_SYNC_FLUSH.  Furthermore, inflate() always defers
+   the allocation of and copying into a sliding window until necessary, which
+   provides the effect documented in zlib.h for Z_FINISH when the entire input
+   stream available.  So the only thing the flush parameter actually does is:
+   when flush is set to Z_FINISH, inflate() cannot return Z_OK.  Instead it
+   will return Z_BUF_ERROR if it has not reached the end of the stream.

+       symbols by length from short to long, and retaining the symbol order
+       for codes with equal lengths.  Then the code starts with all zero bits
+       for the first code of the shortest length, and the codes are integer
+       increments for the same length, and zeros are appended as the length
+       increases.  For the deflate format, these bits are stored backwards
+       from their more natural integer increment ordering, and so when the
+       decoding tables are built in the large loop below, the integer codes
+       are incremented backwards.
+
+       This routine assumes, but does not check, that all of the entries in

+       1..MAXBITS is interpreted as that code length.  zero means that that
+       symbol does not occur in this code.
+
+       The codes are sorted by computing a count of codes for each length,
+       creating from that a table of starting indices for each length in the
+       sorted table, and then entering the symbols in order in the sorted
+       table.  The sorted table is work[], with that space being provided by
+       the caller.
+
+       The length counts are used for other purposes as well, i.e. finding
+       the minimum and maximum length codes, determining if there are any
+       codes at all, checking for a valid set of lengths, and looking ahead
+       at length counts to determine sub-table sizes when building the

+.TH ZLIB 3 "19 Apr 2010"
+.SH NAME
+zlib \- compression/decompression library
+.SH SYNOPSIS
+[see
+.I zlib.h
+for full description]
+.SH DESCRIPTION
+The
+.I zlib
+library is a general purpose data compression library.
+The code is thread safe, assuming that the standard library functions
+used are thread safe, such as memory allocation routines.
+It provides in-memory compression and decompression functions,
+including integrity checks of the uncompressed data.
+This version of the library supports only one compression method (deflation)
+but other algorithms may be added later
+with the same stream interface.
+.LP
+Compression can be done in a single step if the buffers are large enough
+or can be done by repeated calls of the compression function.
+In the latter case,
+the application must provide more input and/or consume the output
+(providing more output space) before each call.
+.LP
+The library also supports reading and writing files in
+.IR gzip (1)
+(.gz) format
+with an interface similar to that of stdio.
+.LP
+The library does not install any signal handler.
+The decoder checks the consistency of the compressed data,
+so the library should never crash even in the case of corrupted input.
+.LP
+All functions of the compression library are documented in the file
+.IR zlib.h .
+The distribution source includes examples of use of the library
+in the files
+.I example.c
+and
+.IR minigzip.c,
+as well as other examples in the
+.IR examples/
+directory.
+.LP
+Changes to this version are documented in the file
+.I ChangeLog
+that accompanies the source.
+.LP
+.I zlib
+is available in Java using the java.util.zip package:
+.IP
+http://java.sun.com/developer/technicalArticles/Programming/compression/
+.LP
+A Perl interface to
+.IR zlib ,
+written by Paul Marquess (pmqs@cpan.org),
+is available at CPAN (Comprehensive Perl Archive Network) sites,
+including:
+.IP
+http://search.cpan.org/~pmqs/IO-Compress-Zlib/
+.LP
+A Python interface to
+.IR zlib ,
+written by A.M. Kuchling (amk@magnet.com),
+is available in Python 1.5 and later versions:
+.IP
+http://www.python.org/doc/lib/module-zlib.html
+.LP
+.I zlib
+is built into
+.IR tcl:
+.IP
+http://wiki.tcl.tk/4610
+.LP
+An experimental package to read and write files in .zip format,
+written on top of
+.I zlib
+by Gilles Vollant (info@winimage.com),
+is available at:
+.IP
+http://www.winimage.com/zLibDll/minizip.html
+and also in the
+.I contrib/minizip
+directory of the main
+.I zlib
+source distribution.
+.SH "SEE ALSO"
+The
+.I zlib
+web site can be found at:
+.IP
+http://zlib.net/
+.LP
+The data format used by the zlib library is described by RFC
+(Request for Comments) 1950 to 1952 in the files:
+.IP
+http://www.ietf.org/rfc/rfc1950.txt (for the zlib header and trailer format)
+.br
+http://www.ietf.org/rfc/rfc1951.txt (for the deflate compressed data format)
+.br
+http://www.ietf.org/rfc/rfc1952.txt (for the gzip header and trailer format)
+.LP
+Mark Nelson wrote an article about
+.I zlib
+for the Jan. 1997 issue of  Dr. Dobb's Journal;
+a copy of the article is available at:
+.IP
+http://marknelson.us/1997/01/01/zlib-engine/
+.SH "REPORTING PROBLEMS"
+Before reporting a problem,
+please check the
+.I zlib
+web site to verify that you have the latest version of
+.IR zlib ;
+otherwise,
+obtain the latest version and see if the problem still exists.
+Please read the
+.I zlib
+FAQ at:
+.IP
+http://zlib.net/zlib_faq.html
+.LP
+before asking for help.
+Send questions and/or comments to zlib@gzip.org,
+or (for the Windows DLL version) to Gilles Vollant (info@winimage.com).

+SHA-1 in C
+By Steve Reid <sreid@sea-to-sky.net>
+100% Public Domain
+
+-----------------
+Modified 7/98
+By James H. Brown <jbrown@burgoyne.com>
+Still 100% Public Domain
+
+Corrected a problem which generated improper hash values on 16 bit machines
+Routine SHA1Update changed from
+	void SHA1Update(SHA1_CTX* context, unsigned char* data, unsigned int
+len)
+to
+	void SHA1Update(SHA1_CTX* context, unsigned char* data, unsigned
+long len)
+
+The 'len' parameter was declared an int which works fine on 32 bit machines.
+However, on 16 bit machines an int is too small for the shifts being done
+against
+it.  This caused the hash function to generate incorrect values if len was
+greater than 8191 (8K - 1) due to the 'len << 3' on line 3 of SHA1Update().
+
+Since the file IO in main() reads 16K at a time, any file 8K or larger would
+be guaranteed to generate the wrong hash (e.g. Test Vector #3, a million
+"a"s).
+
+I also changed the declaration of variables i & j in SHA1Update to
+unsigned long from unsigned int for the same reason.
+
+These changes should make no difference to any 32 bit implementations since
+an
+int and a long are the same size in those environments.
+
+--
+I also corrected a few compiler warnings generated by Borland C.
+1. Added #include <process.h> for exit() prototype
+2. Removed unused variable 'j' in SHA1Final
+3. Changed exit(0) to return(0) at end of main.
+
+ALL changes I made can be located by searching for comments containing 'JHB'

+HISTORY for Lua 5.1
+
+* Changes from version 5.0 to 5.1
+  -------------------------------
+  Language:
+  + new module system.
+  + new semantics for control variables of fors.
+  + new semantics for setn/getn.
+  + new syntax/semantics for varargs.
+  + new long strings and comments.
+  + new `mod' operator (`%')
+  + new length operator #t
+  + metatables for all types
+  API:
+  + new functions: lua_createtable, lua_get(set)field, lua_push(to)integer.
+  + user supplies memory allocator (lua_open becomes lua_newstate).
+  + luaopen_* functions must be called through Lua.
+  Implementation:
+  + new configuration scheme via luaconf.h.
+  + incremental garbage collection.
+  + better handling of end-of-line in the lexer.
+  + fully reentrant parser (new Lua function `load')
+  + better support for 64-bit machines.
+  + native loadlib support for Mac OS X.
+  + standard distribution in only one library (lualib.a merged into lua.a)
+
+* Changes from version 4.0 to 5.0
+  -------------------------------
+  Language:
+  + lexical scoping.
+  + Lua coroutines.
+  + standard libraries now packaged in tables.
+  + tags replaced by metatables and tag methods replaced by metamethods,
+    stored in metatables.
+  + proper tail calls.
+  + each function can have its own global table, which can be shared.
+  + new __newindex metamethod, called when we insert a new key into a table.
+  + new block comments: --[[ ... ]].
+  + new generic for.
+  + new weak tables.
+  + new boolean type.
+  + new syntax "local function".
+  + (f()) returns the first value returned by f.
+  + {f()} fills a table with all values returned by f.
+  + \n ignored in [[\n .
+  + fixed and-or priorities.
+  + more general syntax for function definition (e.g. function a.x.y:f()...end).
+  + more general syntax for function calls (e.g. (print or write)(9)).
+  + new functions (time/date, tmpfile, unpack, require, load*, etc.).
+  API:
+  + chunks are loaded by using lua_load; new luaL_loadfile and luaL_loadbuffer.
+  + introduced lightweight userdata, a simple "void*" without a metatable.
+  + new error handling protocol: the core no longer prints error messages;
+    all errors are reported to the caller on the stack.
+  + new lua_atpanic for host cleanup.
+  + new, signal-safe, hook scheme.
+  Implementation:
+  + new license: MIT.
+  + new, faster, register-based virtual machine.
+  + support for external multithreading and coroutines.
+  + new and consistent error message format.
+  + the core no longer needs "stdio.h" for anything (except for a single
+    use of sprintf to convert numbers to strings).
+  + lua.c now runs the environment variable LUA_INIT, if present. It can
+    be "@filename", to run a file, or the chunk itself.
+  + support for user extensions in lua.c.
+    sample implementation given for command line editing.
+  + new dynamic loading library, active by default on several platforms.
+  + safe garbage-collector metamethods.
+  + precompiled bytecodes checked for integrity (secure binary dostring).
+  + strings are fully aligned.
+  + position capture in string.find.
+  + read('*l') can read lines with embedded zeros.
+
+* Changes from version 3.2 to 4.0
+  -------------------------------
+  Language:
+  + new "break" and "for" statements (both numerical and for tables).
+  + uniform treatment of globals: globals are now stored in a Lua table.
+  + improved error messages.
+  + no more '$debug': full speed *and* full debug information.
+  + new read form: read(N) for next N bytes.
+  + general read patterns now deprecated.
+    (still available with -DCOMPAT_READPATTERNS.)
+  + all return values are passed as arguments for the last function
+    (old semantics still available with -DLUA_COMPAT_ARGRET)
+  + garbage collection tag methods for tables now deprecated.
+  + there is now only one tag method for order.
+  API:
+  + New API: fully re-entrant, simpler, and more efficient.
+  + New debug API.
+  Implementation:
+  + faster than ever: cleaner virtual machine and new hashing algorithm.
+  + non-recursive garbage-collector algorithm.
+  + reduced memory usage for programs with many strings.
+  + improved treatment for memory allocation errors.
+  + improved support for 16-bit machines (we hope).
+  + code now compiles unmodified as both ANSI C and C++.
+  + numbers in bases other than 10 are converted using strtoul.
+  + new -f option in Lua to support #! scripts.
+  + luac can now combine text and binaries.
+
+* Changes from version 3.1 to 3.2
+  -------------------------------
+  + redirected all output in Lua's core to _ERRORMESSAGE and _ALERT.
+  + increased limit on the number of constants and globals per function
+    (from 2^16 to 2^24).
+  + debugging info (lua_debug and hooks) moved into lua_state and new API
+    functions provided to get and set this info.
+  + new debug lib gives full debugging access within Lua.
+  + new table functions "foreachi", "sort", "tinsert", "tremove", "getn".
+  + new io functions "flush", "seek".
+
+* Changes from version 3.0 to 3.1
+  -------------------------------
+  + NEW FEATURE: anonymous functions with closures (via "upvalues").
+  + new syntax:
+    - local variables in chunks.
+    - better scope control with DO block END.
+    - constructors can now be also written: { record-part; list-part }.
+    - more general syntax for function calls and lvalues, e.g.:
+      f(x).y=1
+      o:f(x,y):g(z)
+      f"string" is sugar for f("string")
+  + strings may now contain arbitrary binary data (e.g., embedded zeros).
+  + major code re-organization and clean-up; reduced module interdependecies.
+  + no arbitrary limits on the total number of constants and globals.
+  + support for multiple global contexts.
+  + better syntax error messages.
+  + new traversal functions "foreach" and "foreachvar".
+  + the default for numbers is now double.
+    changing it to use floats or longs is easy.
+  + complete debug information stored in pre-compiled chunks.
+  + sample interpreter now prompts user when run interactively, and also
+    handles control-C interruptions gracefully.
+
+* Changes from version 2.5 to 3.0
+  -------------------------------
+  + NEW CONCEPT: "tag methods".
+    Tag methods replace fallbacks as the meta-mechanism for extending the
+    semantics of Lua. Whereas fallbacks had a global nature, tag methods
+    work on objects having the same tag (e.g., groups of tables).
+    Existing code that uses fallbacks should work without change.
+  + new, general syntax for constructors {[exp] = exp, ... }.
+  + support for handling variable number of arguments in functions (varargs).
+  + support for conditional compilation ($if ... $else ... $end).
+  + cleaner semantics in API simplifies host code.
+  + better support for writing libraries (auxlib.h).
+  + better type checking and error messages in the standard library.
+  + luac can now also undump.
+
+* Changes from version 2.4 to 2.5
+  -------------------------------
+  + io and string libraries are now based on pattern matching;
+    the old libraries are still available for compatibility
+  + dofile and dostring can now return values (via return statement)
+  + better support for 16- and 64-bit machines
+  + expanded documentation, with more examples
+
+* Changes from version 2.2 to 2.4
+  -------------------------------
+  + external compiler creates portable binary files that can be loaded faster
+  + interface for debugging and profiling
+  + new "getglobal" fallback
+  + new functions for handling references to Lua objects
+  + new functions in standard lib
+  + only one copy of each string is stored
+  + expanded documentation, with more examples
+
+* Changes from version 2.1 to 2.2
+  -------------------------------
+  + functions now may be declared with any "lvalue" as a name
+  + garbage collection of functions
+  + support for pipes
+
+* Changes from version 1.1 to 2.1
+  -------------------------------
+  + object-oriented support
+  + fallbacks
+  + simplified syntax for tables
+  + many internal improvements

+INSTALL for Lua 5.1
+
+* Building Lua
+  ------------
+  Lua is built in the src directory, but the build process can be
+  controlled from the top-level Makefile.
+
+  Building Lua on Unix systems should be very easy. First do "make" and
+  see if your platform is listed. If so, just do "make xxx", where xxx
+  is your platform name. The platforms currently supported are:
+    aix ansi bsd freebsd generic linux macosx mingw posix solaris
+
+  If your platform is not listed, try the closest one or posix, generic,
+  ansi, in this order.
+
+  See below for customization instructions and for instructions on how
+  to build with other Windows compilers.
+
+  If you want to check that Lua has been built correctly, do "make test"
+  after building Lua. Also, have a look at the example programs in test.
+
+* Installing Lua
+  --------------
+  Once you have built Lua, you may want to install it in an official
+  place in your system. In this case, do "make install". The official
+  place and the way to install files are defined in Makefile. You must
+  have the right permissions to install files.
+
+  If you want to build and install Lua in one step, do "make xxx install",
+  where xxx is your platform name.
+
+  If you want to install Lua locally, then do "make local". This will
+  create directories bin, include, lib, man, and install Lua there as
+  follows:
+
+    bin:	lua luac
+    include:	lua.h luaconf.h lualib.h lauxlib.h lua.hpp
+    lib:	liblua.a
+    man/man1:	lua.1 luac.1
+
+  These are the only directories you need for development.
+
+  There are man pages for lua and luac, in both nroff and html, and a
+  reference manual in html in doc, some sample code in test, and some
+  useful stuff in etc. You don't need these directories for development.
+
+  If you want to install Lua locally, but in some other directory, do
+  "make install INSTALL_TOP=xxx", where xxx is your chosen directory.
+
+  See below for instructions for Windows and other systems.
+
+* Customization
+  -------------
+  Three things can be customized by editing a file:
+    - Where and how to install Lua -- edit Makefile.
+    - How to build Lua -- edit src/Makefile.
+    - Lua features -- edit src/luaconf.h.
+
+  You don't actually need to edit the Makefiles because you may set the
+  relevant variables when invoking make.
+
+  On the other hand, if you need to select some Lua features, you'll need
+  to edit src/luaconf.h. The edited file will be the one installed, and
+  it will be used by any Lua clients that you build, to ensure consistency.
+
+  We strongly recommend that you enable dynamic loading. This is done
+  automatically for all platforms listed above that have this feature
+  (and also Windows). See src/luaconf.h and also src/Makefile.
+
+* Building Lua on Windows and other systems
+  -----------------------------------------
+  If you're not using the usual Unix tools, then the instructions for
+  building Lua depend on the compiler you use. You'll need to create
+  projects (or whatever your compiler uses) for building the library,
+  the interpreter, and the compiler, as follows:
+
+  library:	lapi.c lcode.c ldebug.c ldo.c ldump.c lfunc.c lgc.c llex.c
+		lmem.c lobject.c lopcodes.c lparser.c lstate.c lstring.c
+		ltable.c ltm.c lundump.c lvm.c lzio.c
+		lauxlib.c lbaselib.c ldblib.c liolib.c lmathlib.c loslib.c
+		ltablib.c lstrlib.c loadlib.c linit.c
+
+  interpreter:	library, lua.c
+
+  compiler:	library, luac.c print.c
+
+  If you use Visual Studio .NET, you can use etc/luavs.bat in its
+  "Command Prompt".
+
+  If all you want is to build the Lua interpreter, you may put all .c files
+  in a single project, except for luac.c and print.c. Or just use etc/all.c.
+
+  To use Lua as a library in your own programs, you'll need to know how to
+  create and use libraries with your compiler.
+
+  As mentioned above, you may edit luaconf.h to select some features before
+  building Lua.
+

+* Installation
+  ------------
+  Lua is implemented in pure ANSI C, and compiles unmodified in all known
+  platforms that have an ANSI C compiler. In most Unix-like platforms, simply
+  do "make" with a suitable target. See INSTALL for detailed instructions.
+
+* Origin
+  ------
+  Lua is developed at Lua.org, a laboratory of the Department of Computer
+  Science of PUC-Rio (the Pontifical Catholic University of Rio de Janeiro
+  in Brazil).
+  For more information about the authors, see http://www.lua.org/authors.html .

+.SH NAME
+lua \- Lua interpreter
+.SH SYNOPSIS
+.B lua
+[
+.I options
+]
+[
+.I script
+[
+.I args
+]
+]
+.SH DESCRIPTION
+.B lua
+is the stand-alone Lua interpreter.
+It loads and executes Lua programs,
+either in textual source form or
+in precompiled binary form.
+(Precompiled binaries are output by
+.BR luac ,
+the Lua compiler.)
+.B lua
+can be used as a batch interpreter and also interactively.
+.LP
+The given
+.I options
+(see below)
+are executed and then
+the Lua program in file
+.I script
+is loaded and executed.
+The given
+.I args
+are available to
+.I script
+as strings in a global table named
+.BR arg .
+If these arguments contain spaces or other characters special to the shell,
+then they should be quoted
+(but note that the quotes will be removed by the shell).
+The arguments in
+.B arg
+start at 0,
+which contains the string
+.RI ' script '.
+The index of the last argument is stored in
+.BR arg.n .
+The arguments given in the command line before
+.IR script ,
+including the name of the interpreter,
+are available in negative indices in
+.BR arg .
+.LP
+At the very start,
+before even handling the command line,
+.B lua
+executes the contents of the environment variable
+.BR LUA_INIT ,
+if it is defined.
+If the value of
+.B LUA_INIT
+is of the form
+.RI '@ filename ',
+then
+.I filename
+is executed.
+Otherwise, the string is assumed to be a Lua statement and is executed.
+.LP
+Options start with
+.B '\-'
+and are described below.
+You can use
+.B "'\--'"
+to signal the end of options.
+.LP
+If no arguments are given,
+then
+.B "\-v \-i"
+is assumed when the standard input is a terminal;
+otherwise,
+.B "\-"
+is assumed.
+.LP
+In interactive mode,
+.B lua
+prompts the user,
+reads lines from the standard input,
+and executes them as they are read.
+If a line does not contain a complete statement,
+then a secondary prompt is displayed and
+lines are read until a complete statement is formed or
+a syntax error is found.
+So, one way to interrupt the reading of an incomplete statement is
+to force a syntax error:
+adding a
+.B ';' 
+in the middle of a statement is a sure way of forcing a syntax error
+(except inside multiline strings and comments; these must be closed explicitly).
+If a line starts with
+.BR '=' ,
+then
+.B lua
+displays the values of all the expressions in the remainder of the
+line. The expressions must be separated by commas.
+The primary prompt is the value of the global variable
+.BR _PROMPT ,
+if this value is a string;
+otherwise, the default prompt is used.
+Similarly, the secondary prompt is the value of the global variable
+.BR _PROMPT2 .
+So,
+to change the prompts,
+set the corresponding variable to a string of your choice.
+You can do that after calling the interpreter
+or on the command line
+(but in this case you have to be careful with quotes
+if the prompt string contains a space; otherwise you may confuse the shell.)
+The default prompts are "> " and ">> ".

+.SH NAME
+luac \- Lua compiler
+.SH SYNOPSIS
+.B luac
+[
+.I options
+] [
+.I filenames
+]
+.SH DESCRIPTION
+.B luac
+is the Lua compiler.
+It translates programs written in the Lua programming language
+into binary files that can be later loaded and executed.
+.LP
+The main advantages of precompiling chunks are:
+faster loading,
+protecting source code from accidental user changes,
+and
+off-line syntax checking.
+.LP
+Pre-compiling does not imply faster execution
+because in Lua chunks are always compiled into bytecodes before being executed.
+.B luac
+simply allows those bytecodes to be saved in a file for later execution.
+.LP
+Pre-compiled chunks are not necessarily smaller than the corresponding source.
+The main goal in pre-compiling is faster loading.
+.LP
+The binary files created by
+.B luac
+are portable only among architectures with the same word size and byte order.
+.LP
+.B luac
+produces a single output file containing the bytecodes
+for all source files given.
+By default,
+the output file is named
+.BR luac.out ,
+but you can change this with the
+.B \-o
+option.
+.LP
+In the command line,
+you can mix
+text files containing Lua source and
+binary files containing precompiled chunks.
+This is useful to combine several precompiled chunks,
+even from different (but compatible) platforms,
+into a single precompiled chunk.
+.LP
+You can use
+.B "'\-'"
+to indicate the standard input as a source file
+and
+.B "'\--'"
+to signal the end of options
+(that is,
+all remaining arguments will be treated as files even if they start with
+.BR "'\-'" ).
+.LP
+The internal format of the binary files produced by
+.B luac
+is likely to change when a new version of Lua is released.
+So,
+save the source files of all Lua programs that you precompile.
+.LP
+.SH OPTIONS
+Options must be separate.
+.TP
+.B \-l
+produce a listing of the compiled bytecode for Lua's virtual machine.
+Listing bytecodes is useful to learn about Lua's virtual machine.
+If no files are given, then
+.B luac
+loads
+.B luac.out
+and lists its contents.
+.TP
+.BI \-o " file"
+output to
+.IR file ,
+instead of the default
+.BR luac.out .
+(You can use
+.B "'\-'"
+for standard output,
+but not on platforms that open standard output in text mode.)
+The output file may be a source file because
+all files are loaded before the output file is written.
+Be careful not to overwrite precious files.
+.TP
+.B \-p
+load files but do not generate any output file.
+Used mainly for syntax checking and for testing precompiled chunks:
+corrupted files will probably generate errors when loaded.
+Lua always performs a thorough integrity test on precompiled chunks.
+Bytecode that passes this test is completely safe,
+in the sense that it will not break the interpreter.
+However,
+there is no guarantee that such code does anything sensible.
+(None can be given, because the halting problem is unsolvable.)
+If no files are given, then
+.B luac
+loads
+.B luac.out
+and tests its contents.
+No messages are displayed if the file passes the integrity test.
+.TP
+.B \-s

+<B>luac</B>
+[
+<I>options</I>
+] [
+<I>filenames</I>
+]
+<H2>DESCRIPTION</H2>
+<B>luac</B>
+is the Lua compiler.
+It translates programs written in the Lua programming language
+into binary files that can be later loaded and executed.
+<P>
+The main advantages of precompiling chunks are:
+faster loading,
+protecting source code from accidental user changes,
+and
+off-line syntax checking.
+<P>
+Precompiling does not imply faster execution
+because in Lua chunks are always compiled into bytecodes before being executed.
+<B>luac</B>
+simply allows those bytecodes to be saved in a file for later execution.
+<P>
+Precompiled chunks are not necessarily smaller than the corresponding source.
+The main goal in precompiling is faster loading.
+<P>
+The binary files created by
+<B>luac</B>
+are portable only among architectures with the same word size and byte order.
+<P>
+<B>luac</B>
+produces a single output file containing the bytecodes
+for all source files given.
+By default,
+the output file is named
+<B>luac.out</B>,
+but you can change this with the
+<B>-o</B>
+option.
+<P>
+In the command line,
+you can mix
+text files containing Lua source and
+binary files containing precompiled chunks.
+This is useful because several precompiled chunks,
+even from different (but compatible) platforms,
+can be combined into a single precompiled chunk.
+<P>
+You can use
+<B>'-'</B>
+to indicate the standard input as a source file
+and
+<B>'--'</B>
+to signal the end of options
+(that is,
+all remaining arguments will be treated as files even if they start with
+<B>'-'</B>).
+<P>
+The internal format of the binary files produced by
+<B>luac</B>
+is likely to change when a new version of Lua is released.
+So,
+save the source files of all Lua programs that you precompile.
+<P>
+<H2>OPTIONS</H2>
+Options must be separate.
+<P>
+<B>-l</B>
+produce a listing of the compiled bytecode for Lua's virtual machine.
+Listing bytecodes is useful to learn about Lua's virtual machine.
+If no files are given, then
+<B>luac</B>
+loads
+<B>luac.out</B>
+and lists its contents.
+<P>
+<B>-o </B><I>file</I>
+output to
+<I>file</I>,
+instead of the default
+<B>luac.out</B>.
+(You can use
+<B>'-'</B>
+for standard output,
+but not on platforms that open standard output in text mode.)
+The output file may be a source file because
+all files are loaded before the output file is written.
+Be careful not to overwrite precious files.
+<P>
+<B>-p</B>
+load files but do not generate any output file.
+Used mainly for syntax checking and for testing precompiled chunks:
+corrupted files will probably generate errors when loaded.
+Lua always performs a thorough integrity test on precompiled chunks.
+Bytecode that passes this test is completely safe,
+in the sense that it will not break the interpreter.
+However,
+there is no guarantee that such code does anything sensible.
+(None can be given, because the halting problem is unsolvable.)
+If no files are given, then
+<B>luac</B>
+loads
+<B>luac.out</B>
+and tests its contents.
+No messages are displayed if the file passes the integrity test.

+<h1>1 - <a name="1">Introduction</a></h1>
+
+<p>
+Lua is an extension programming language designed to support
+general procedural programming with data description
+facilities.
+It also offers good support for object-oriented programming,
+functional programming, and data-driven programming.
+Lua is intended to be used as a powerful, light-weight
+scripting language for any program that needs one.
+Lua is implemented as a library, written in <em>clean</em> C
+(that is, in the common subset of ANSI&nbsp;C and C++).
+
+
+<p>
+Being an extension language, Lua has no notion of a "main" program:
+it only works <em>embedded</em> in a host client,
+called the <em>embedding program</em> or simply the <em>host</em>.
+This host program can invoke functions to execute a piece of Lua code,
+can write and read Lua variables,
+and can register C&nbsp;functions to be called by Lua code.
+Through the use of C&nbsp;functions, Lua can be augmented to cope with
+a wide range of different domains,
+thus creating customized programming languages sharing a syntactical framework.
+The Lua distribution includes a sample host program called <code>lua</code>,
+which uses the Lua library to offer a complete, stand-alone Lua interpreter.
+
+
+<p>
+Lua is free software,
+and is provided as usual with no guarantees,
+as stated in its license.
+The implementation described in this manual is available
+at Lua's official web site, <code>www.lua.org</code>.
+
+
+<p>
+Like any other reference manual,
+this document is dry in places.
+For a discussion of the decisions behind the design of Lua,
+see the technical papers available at Lua's web site.
+For a detailed introduction to programming in Lua,
+see Roberto's book, <em>Programming in Lua (Second Edition)</em>.
+
+
+
+<h1>2 - <a name="2">The Language</a></h1>
+
+<p>
+This section describes the lexis, the syntax, and the semantics of Lua.
+In other words,
+this section describes
+which tokens are valid,
+how they can be combined,
+and what their combinations mean.
+
+
+<p>
+The language constructs will be explained using the usual extended BNF notation,
+in which
+{<em>a</em>}&nbsp;means&nbsp;0 or more <em>a</em>'s, and
+[<em>a</em>]&nbsp;means an optional <em>a</em>.
+Non-terminals are shown like non-terminal,
+keywords are shown like <b>kword</b>,
+and other terminal symbols are shown like `<b>=</b>&acute;.
+The complete syntax of Lua can be found at the end of this manual.
+
+
+
+<h2>2.1 - <a name="2.1">Lexical Conventions</a></h2>
+
+<p>
+<em>Names</em>
+(also called <em>identifiers</em>)
+in Lua can be any string of letters,
+digits, and underscores,
+not beginning with a digit.
+This coincides with the definition of names in most languages.
+(The definition of letter depends on the current locale:
+any character considered alphabetic by the current locale
+can be used in an identifier.)
+Identifiers are used to name variables and table fields.
+
+
+<p>
+The following <em>keywords</em> are reserved
+and cannot be used as names:
+
+
+<pre>
+     and       break     do        else      elseif
+     end       false     for       function  if
+     in        local     nil       not       or
+     repeat    return    then      true      until     while
+</pre>
+
+<p>
+Lua is a case-sensitive language:
+<code>and</code> is a reserved word, but <code>And</code> and <code>AND</code>
+are two different, valid names.
+As a convention, names starting with an underscore followed by
+uppercase letters (such as <code>_VERSION</code>)
+are reserved for internal global variables used by Lua.
+
+
+<p>
+The following strings denote other tokens:
+
+<pre>
+     +     -     *     /     %     ^     #
+     ==    ~=    &lt;=    &gt;=    &lt;     &gt;     =
+     (     )     {     }     [     ]
+     ;     :     ,     .     ..    ...
+</pre>
+
+<p>
+<em>Literal strings</em>
+can be delimited by matching single or double quotes,
+and can contain the following C-like escape sequences:
+'<code>\a</code>' (bell),
+'<code>\b</code>' (backspace),
+'<code>\f</code>' (form feed),
+'<code>\n</code>' (newline),
+'<code>\r</code>' (carriage return),
+'<code>\t</code>' (horizontal tab),
+'<code>\v</code>' (vertical tab),
+'<code>\\</code>' (backslash),
+'<code>\"</code>' (quotation mark [double quote]),
+and '<code>\'</code>' (apostrophe [single quote]).
+Moreover, a backslash followed by a real newline
+results in a newline in the string.
+A character in a string may also be specified by its numerical value
+using the escape sequence <code>\<em>ddd</em></code>,
+where <em>ddd</em> is a sequence of up to three decimal digits.
+(Note that if a numerical escape is to be followed by a digit,
+it must be expressed using exactly three digits.)
+Strings in Lua may contain any 8-bit value, including embedded zeros,
+which can be specified as '<code>\0</code>'.
+
+
+<p>
+To put a double (single) quote, a newline, a backslash,
+a carriage return,
+or an embedded zero
+inside a literal string enclosed by double (single) quotes
+you must use an escape sequence.
+Any other character may be directly inserted into the literal.
+(Some control characters may cause problems for the file system,
+but Lua has no problem with them.)
+
+
+<p>
+Literal strings can also be defined using a long format
+enclosed by <em>long brackets</em>.
+We define an <em>opening long bracket of level <em>n</em></em> as an opening
+square bracket followed by <em>n</em> equal signs followed by another
+opening square bracket.
+So, an opening long bracket of level&nbsp;0 is written as <code>[[</code>,
+an opening long bracket of level&nbsp;1 is written as <code>[=[</code>,
+and so on.
+A <em>closing long bracket</em> is defined similarly;
+for instance, a closing long bracket of level&nbsp;4 is written as <code>]====]</code>.
+A long string starts with an opening long bracket of any level and
+ends at the first closing long bracket of the same level.
+Literals in this bracketed form may run for several lines,
+do not interpret any escape sequences,
+and ignore long brackets of any other level.
+They may contain anything except a closing bracket of the proper level.
+
+
+<p>
+For convenience,
+when the opening long bracket is immediately followed by a newline,
+the newline is not included in the string.
+As an example, in a system using ASCII
+(in which '<code>a</code>' is coded as&nbsp;97,
+newline is coded as&nbsp;10, and '<code>1</code>' is coded as&nbsp;49),
+the five literals below denote the same string:
+
+<pre>
+     a = 'alo\n123"'
+     a = "alo\n123\""
+     a = '\97lo\10\04923"'
+     a = [[alo
+     123"]]
+     a = [==[
+     alo
+     123"]==]
+</pre>
+
+<p>
+A <em>numerical constant</em> may be written with an optional decimal part
+and an optional decimal exponent.
+Lua also accepts integer hexadecimal constants,
+by prefixing them with <code>0x</code>.
+Examples of valid numerical constants are
+
+<pre>
+     3   3.0   3.1416   314.16e-2   0.31416E1   0xff   0x56
+</pre>
+
+<p>
+A <em>comment</em> starts with a double hyphen (<code>--</code>)
+anywhere outside a string.
+If the text immediately after <code>--</code> is not an opening long bracket,
+the comment is a <em>short comment</em>,
+which runs until the end of the line.
+Otherwise, it is a <em>long comment</em>,
+which runs until the corresponding closing long bracket.
+Long comments are frequently used to disable code temporarily.
+
+
+
+
+
+<h2>2.2 - <a name="2.2">Values and Types</a></h2>
+
+<p>
+Lua is a <em>dynamically typed language</em>.
+This means that
+variables do not have types; only values do.
+There are no type definitions in the language.
+All values carry their own type.
+
+
+<p>
+All values in Lua are <em>first-class values</em>.
+This means that all values can be stored in variables,
+passed as arguments to other functions, and returned as results.
+
+
+<p>
+There are eight basic types in Lua:
+<em>nil</em>, <em>boolean</em>, <em>number</em>,
+<em>string</em>, <em>function</em>, <em>userdata</em>,
+<em>thread</em>, and <em>table</em>.
+<em>Nil</em> is the type of the value <b>nil</b>,
+whose main property is to be different from any other value;
+it usually represents the absence of a useful value.
+<em>Boolean</em> is the type of the values <b>false</b> and <b>true</b>.
+Both <b>nil</b> and <b>false</b> make a condition false;
+any other value makes it true.
+<em>Number</em> represents real (double-precision floating-point) numbers.
+(It is easy to build Lua interpreters that use other
+internal representations for numbers,
+such as single-precision float or long integers;
+see file <code>luaconf.h</code>.)
+<em>String</em> represents arrays of characters.
+
+Lua is 8-bit clean:
+strings may contain any 8-bit character,
+including embedded zeros ('<code>\0</code>') (see <a href="#2.1">&sect;2.1</a>).
+
+
+<p>
+Lua can call (and manipulate) functions written in Lua and
+functions written in C
+(see <a href="#2.5.8">&sect;2.5.8</a>).
+
+
+<p>
+The type <em>userdata</em> is provided to allow arbitrary C&nbsp;data to
+be stored in Lua variables.
+This type corresponds to a block of raw memory
+and has no pre-defined operations in Lua,
+except assignment and identity test.
+However, by using <em>metatables</em>,
+the programmer can define operations for userdata values
+(see <a href="#2.8">&sect;2.8</a>).
+Userdata values cannot be created or modified in Lua,
+only through the C&nbsp;API.
+This guarantees the integrity of data owned by the host program.
+
+
+<p>
+The type <em>thread</em> represents independent threads of execution
+and it is used to implement coroutines (see <a href="#2.11">&sect;2.11</a>).
+Do not confuse Lua threads with operating-system threads.
+Lua supports coroutines on all systems,
+even those that do not support threads.
+
+
+<p>
+The type <em>table</em> implements associative arrays,
+that is, arrays that can be indexed not only with numbers,
+but with any value (except <b>nil</b>).
+Tables can be <em>heterogeneous</em>;
+that is, they can contain values of all types (except <b>nil</b>).
+Tables are the sole data structuring mechanism in Lua;
+they may be used to represent ordinary arrays,
+symbol tables, sets, records, graphs, trees, etc.
+To represent records, Lua uses the field name as an index.
+The language supports this representation by
+providing <code>a.name</code> as syntactic sugar for <code>a["name"]</code>.
+There are several convenient ways to create tables in Lua
+(see <a href="#2.5.7">&sect;2.5.7</a>).
+
+
+<p>
+Like indices,
+the value of a table field can be of any type (except <b>nil</b>).
+In particular,
+because functions are first-class values,
+table fields may contain functions.
+Thus tables may also carry <em>methods</em> (see <a href="#2.5.9">&sect;2.5.9</a>).
+
+
+<p>
+Tables, functions, threads, and (full) userdata values are <em>objects</em>:
+variables do not actually <em>contain</em> these values,
+only <em>references</em> to them.
+Assignment, parameter passing, and function returns
+always manipulate references to such values;
+these operations do not imply any kind of copy.
+
+
+<p>
+The library function <a href="#pdf-type"><code>type</code></a> returns a string describing the type
+of a given value.
+
+
+
+<h3>2.2.1 - <a name="2.2.1">Coercion</a></h3>
+
+<p>
+Lua provides automatic conversion between
+string and number values at run time.
+Any arithmetic operation applied to a string tries to convert
+this string to a number, following the usual conversion rules.
+Conversely, whenever a number is used where a string is expected,
+the number is converted to a string, in a reasonable format.
+For complete control over how numbers are converted to strings,
+use the <code>format</code> function from the string library
+(see <a href="#pdf-string.format"><code>string.format</code></a>).
+
+
+
+
+
+
+
+<h2>2.3 - <a name="2.3">Variables</a></h2>
+
+<p>
+Variables are places that store values.
+
+There are three kinds of variables in Lua:
+global variables, local variables, and table fields.
+
+
+<p>
+A single name can denote a global variable or a local variable
+(or a function's formal parameter,
+which is a particular kind of local variable):
+
+<pre>
+	var ::= Name
+</pre><p>
+Name denotes identifiers, as defined in <a href="#2.1">&sect;2.1</a>.
+
+
+<p>
+Any variable is assumed to be global unless explicitly declared
+as a local (see <a href="#2.4.7">&sect;2.4.7</a>).
+Local variables are <em>lexically scoped</em>:
+local variables can be freely accessed by functions
+defined inside their scope (see <a href="#2.6">&sect;2.6</a>).
+
+
+<p>
+Before the first assignment to a variable, its value is <b>nil</b>.
+
+
+<p>
+Square brackets are used to index a table:
+
+<pre>
+	var ::= prefixexp `<b>[</b>&acute; exp `<b>]</b>&acute;
+</pre><p>
+The meaning of accesses to global variables 
+and table fields can be changed via metatables.
+An access to an indexed variable <code>t[i]</code> is equivalent to
+a call <code>gettable_event(t,i)</code>.
+(See <a href="#2.8">&sect;2.8</a> for a complete description of the
+<code>gettable_event</code> function.
+This function is not defined or callable in Lua.
+We use it here only for explanatory purposes.)
+
+
+<p>
+The syntax <code>var.Name</code> is just syntactic sugar for
+<code>var["Name"]</code>:
+
+<pre>
+	var ::= prefixexp `<b>.</b>&acute; Name
+</pre>
+
+<p>
+All global variables live as fields in ordinary Lua tables,
+called <em>environment tables</em> or simply
+<em>environments</em> (see <a href="#2.9">&sect;2.9</a>).
+Each function has its own reference to an environment,
+so that all global variables in this function
+will refer to this environment table.
+When a function is created,
+it inherits the environment from the function that created it.
+To get the environment table of a Lua function,
+you call <a href="#pdf-getfenv"><code>getfenv</code></a>.
+To replace it,
+you call <a href="#pdf-setfenv"><code>setfenv</code></a>.
+(You can only manipulate the environment of C&nbsp;functions
+through the debug library; (see <a href="#5.9">&sect;5.9</a>).)
+
+
+<p>
+An access to a global variable <code>x</code>
+is equivalent to <code>_env.x</code>,
+which in turn is equivalent to
+
+<pre>
+     gettable_event(_env, "x")
+</pre><p>
+where <code>_env</code> is the environment of the running function.
+(See <a href="#2.8">&sect;2.8</a> for a complete description of the
+<code>gettable_event</code> function.
+This function is not defined or callable in Lua.
+Similarly, the <code>_env</code> variable is not defined in Lua.
+We use them here only for explanatory purposes.)
+
+
+
+
+
+<h2>2.4 - <a name="2.4">Statements</a></h2>
+
+<p>
+Lua supports an almost conventional set of statements,
+similar to those in Pascal or C.
+This set includes
+assignment, control structures, function calls,
+and variable declarations.
+
+
+
+<h3>2.4.1 - <a name="2.4.1">Chunks</a></h3>
+
+<p>
+The unit of execution of Lua is called a <em>chunk</em>.
+A chunk is simply a sequence of statements,
+which are executed sequentially.
+Each statement can be optionally followed by a semicolon:
+
+<pre>
+	chunk ::= {stat [`<b>;</b>&acute;]}
+</pre><p>
+There are no empty statements and thus '<code>;;</code>' is not legal.
+
+
+<p>
+Lua handles a chunk as the body of an anonymous function 
+with a variable number of arguments
+(see <a href="#2.5.9">&sect;2.5.9</a>).
+As such, chunks can define local variables,
+receive arguments, and return values.
+
+
+<p>
+A chunk may be stored in a file or in a string inside the host program.
+When a chunk is executed, first it is pre-compiled into instructions for
+a virtual machine,
+and then the compiled code is executed
+by an interpreter for the virtual machine.
+
+
+<p>
+Chunks may also be pre-compiled into binary form;
+see program <code>luac</code> for details.
+Programs in source and compiled forms are interchangeable;
+Lua automatically detects the file type and acts accordingly.
+
+
+
+
+
+
+<h3>2.4.2 - <a name="2.4.2">Blocks</a></h3><p>
+A block is a list of statements;
+syntactically, a block is the same as a chunk:
+
+<pre>
+	block ::= chunk
+</pre>
+
+<p>
+A block may be explicitly delimited to produce a single statement:
+
+<pre>
+	stat ::= <b>do</b> block <b>end</b>
+</pre><p>
+Explicit blocks are useful
+to control the scope of variable declarations.
+Explicit blocks are also sometimes used to
+add a <b>return</b> or <b>break</b> statement in the middle
+of another block (see <a href="#2.4.4">&sect;2.4.4</a>).
+
+
+
+
+
+<h3>2.4.3 - <a name="2.4.3">Assignment</a></h3>
+
+<p>
+Lua allows multiple assignment.
+Therefore, the syntax for assignment
+defines a list of variables on the left side
+and a list of expressions on the right side.
+The elements in both lists are separated by commas:
+
+<pre>
+	stat ::= varlist `<b>=</b>&acute; explist
+	varlist ::= var {`<b>,</b>&acute; var}
+	explist ::= exp {`<b>,</b>&acute; exp}
+</pre><p>
+Expressions are discussed in <a href="#2.5">&sect;2.5</a>.
+
+
+<p>
+Before the assignment,
+the list of values is <em>adjusted</em> to the length of
+the list of variables.
+If there are more values than needed,
+the excess values are thrown away.
+If there are fewer values than needed,
+the list is extended with as many  <b>nil</b>'s as needed.
+If the list of expressions ends with a function call,
+then all values returned by this call enter in the list of values,
+before the adjustment
+(except when the call is enclosed in parentheses; see <a href="#2.5">&sect;2.5</a>).
+
+
+<p>
+The assignment statement first evaluates all its expressions
+and only then are the assignments performed.
+Thus the code
+
+<pre>
+     i = 3
+     i, a[i] = i+1, 20
+</pre><p>
+sets <code>a[3]</code> to 20, without affecting <code>a[4]</code>
+because the <code>i</code> in <code>a[i]</code> is evaluated (to 3)
+before it is assigned&nbsp;4.
+Similarly, the line
+
+<pre>
+     x, y = y, x
+</pre><p>
+exchanges the values of <code>x</code> and <code>y</code>.
+
+
+<p>
+The meaning of assignments to global variables
+and table fields can be changed via metatables.
+An assignment to an indexed variable <code>t[i] = val</code> is equivalent to
+<code>settable_event(t,i,val)</code>.
+(See <a href="#2.8">&sect;2.8</a> for a complete description of the
+<code>settable_event</code> function.
+This function is not defined or callable in Lua.
+We use it here only for explanatory purposes.)
+
+
+<p>
+An assignment to a global variable <code>x = val</code>
+is equivalent to the assignment
+<code>_env.x = val</code>,
+which in turn is equivalent to
+
+<pre>
+     settable_event(_env, "x", val)
+</pre><p>
+where <code>_env</code> is the environment of the running function.
+(The <code>_env</code> variable is not defined in Lua.
+We use it here only for explanatory purposes.)
+
+
+
+
+
+<h3>2.4.4 - <a name="2.4.4">Control Structures</a></h3><p>
+The control structures
+<b>if</b>, <b>while</b>, and <b>repeat</b> have the usual meaning and
+familiar syntax:
+
+
+
+
+<pre>
+	stat ::= <b>while</b> exp <b>do</b> block <b>end</b>
+	stat ::= <b>repeat</b> block <b>until</b> exp
+	stat ::= <b>if</b> exp <b>then</b> block {<b>elseif</b> exp <b>then</b> block} [<b>else</b> block] <b>end</b>
+</pre><p>
+Lua also has a <b>for</b> statement, in two flavors (see <a href="#2.4.5">&sect;2.4.5</a>).
+
+
+<p>
+The condition expression of a
+control structure may return any value.
+Both <b>false</b> and <b>nil</b> are considered false.
+All values different from <b>nil</b> and <b>false</b> are considered true
+(in particular, the number 0 and the empty string are also true).
+
+
+<p>
+In the <b>repeat</b>&ndash;<b>until</b> loop,
+the inner block does not end at the <b>until</b> keyword,
+but only after the condition.
+So, the condition can refer to local variables
+declared inside the loop block.
+
+
+<p>
+The <b>return</b> statement is used to return values
+from a function or a chunk (which is just a function).
+
+Functions and chunks may return more than one value,
+so the syntax for the <b>return</b> statement is
+
+<pre>
+	stat ::= <b>return</b> [explist]
+</pre>
+
+<p>
+The <b>break</b> statement is used to terminate the execution of a
+<b>while</b>, <b>repeat</b>, or <b>for</b> loop,
+skipping to the next statement after the loop:
+
+
+<pre>
+	stat ::= <b>break</b>
+</pre><p>
+A <b>break</b> ends the innermost enclosing loop.
+
+
+<p>
+The <b>return</b> and <b>break</b>
+statements can only be written as the <em>last</em> statement of a block.
+If it is really necessary to <b>return</b> or <b>break</b> in the
+middle of a block,
+then an explicit inner block can be used,
+as in the idioms
+<code>do return end</code> and <code>do break end</code>,
+because now <b>return</b> and <b>break</b> are the last statements in
+their (inner) blocks.
+
+
+
+
+
+<h3>2.4.5 - <a name="2.4.5">For Statement</a></h3>
+
+<p>
+
+The <b>for</b> statement has two forms:
+one numeric and one generic.
+
+
+<p>
+The numeric <b>for</b> loop repeats a block of code while a
+control variable runs through an arithmetic progression.
+It has the following syntax:
+
+<pre>
+	stat ::= <b>for</b> Name `<b>=</b>&acute; exp `<b>,</b>&acute; exp [`<b>,</b>&acute; exp] <b>do</b> block <b>end</b>
+</pre><p>
+The <em>block</em> is repeated for <em>name</em> starting at the value of
+the first <em>exp</em>, until it passes the second <em>exp</em> by steps of the
+third <em>exp</em>.
+More precisely, a <b>for</b> statement like
+
+<pre>
+     for v = <em>e1</em>, <em>e2</em>, <em>e3</em> do <em>block</em> end
+</pre><p>
+is equivalent to the code:
+
+<pre>
+     do
+       local <em>var</em>, <em>limit</em>, <em>step</em> = tonumber(<em>e1</em>), tonumber(<em>e2</em>), tonumber(<em>e3</em>)
+       if not (<em>var</em> and <em>limit</em> and <em>step</em>) then error() end
+       while (<em>step</em> &gt; 0 and <em>var</em> &lt;= <em>limit</em>) or (<em>step</em> &lt;= 0 and <em>var</em> &gt;= <em>limit</em>) do
+         local v = <em>var</em>
+         <em>block</em>
+         <em>var</em> = <em>var</em> + <em>step</em>
+       end
+     end
+</pre><p>
+Note the following:
+
+<ul>
+
+<li>
+All three control expressions are evaluated only once,
+before the loop starts.
+They must all result in numbers.
+</li>
+
+<li>
+<code><em>var</em></code>, <code><em>limit</em></code>, and <code><em>step</em></code> are invisible variables.
+The names are here for explanatory purposes only.
+</li>
+
+<li>
+If the third expression (the step) is absent,
+then a step of&nbsp;1 is used.
+</li>
+
+<li>
+You can use <b>break</b> to exit a <b>for</b> loop.
+</li>
+
+<li>
+The loop variable <code>v</code> is local to the loop;
+you cannot use its value after the <b>for</b> ends or is broken.
+If you need this value,
+assign it to another variable before breaking or exiting the loop.
+</li>
+
+</ul>
+
+<p>
+The generic <b>for</b> statement works over functions,
+called <em>iterators</em>.
+On each iteration, the iterator function is called to produce a new value,
+stopping when this new value is <b>nil</b>.
+The generic <b>for</b> loop has the following syntax:
+
+<pre>
+	stat ::= <b>for</b> namelist <b>in</b> explist <b>do</b> block <b>end</b>
+	namelist ::= Name {`<b>,</b>&acute; Name}
+</pre><p>
+A <b>for</b> statement like
+
+<pre>
+     for <em>var_1</em>, &middot;&middot;&middot;, <em>var_n</em> in <em>explist</em> do <em>block</em> end
+</pre><p>
+is equivalent to the code:
+
+<pre>
+     do
+       local <em>f</em>, <em>s</em>, <em>var</em> = <em>explist</em>
+       while true do
+         local <em>var_1</em>, &middot;&middot;&middot;, <em>var_n</em> = <em>f</em>(<em>s</em>, <em>var</em>)
+         <em>var</em> = <em>var_1</em>
+         if <em>var</em> == nil then break end
+         <em>block</em>
+       end
+     end
+</pre><p>
+Note the following:
+
+<ul>
+
+<li>
+<code><em>explist</em></code> is evaluated only once.
+Its results are an <em>iterator</em> function,
+a <em>state</em>,
+and an initial value for the first <em>iterator variable</em>.
+</li>
+
+<li>
+<code><em>f</em></code>, <code><em>s</em></code>, and <code><em>var</em></code> are invisible variables.
+The names are here for explanatory purposes only.
+</li>
+
+<li>
+You can use <b>break</b> to exit a <b>for</b> loop.
+</li>
+
+<li>
+The loop variables <code><em>var_i</em></code> are local to the loop;
+you cannot use their values after the <b>for</b> ends.
+If you need these values,
+then assign them to other variables before breaking or exiting the loop.
+</li>
+
+</ul>
+
+
+
+
+<h3>2.4.6 - <a name="2.4.6">Function Calls as Statements</a></h3><p>
+To allow possible side-effects,
+function calls can be executed as statements:
+
+<pre>
+	stat ::= functioncall
+</pre><p>
+In this case, all returned values are thrown away.
+Function calls are explained in <a href="#2.5.8">&sect;2.5.8</a>.
+
+
+
+
+
+<h3>2.4.7 - <a name="2.4.7">Local Declarations</a></h3><p>
+Local variables may be declared anywhere inside a block.
+The declaration may include an initial assignment:
+
+<pre>
+	stat ::= <b>local</b> namelist [`<b>=</b>&acute; explist]
+</pre><p>
+If present, an initial assignment has the same semantics
+of a multiple assignment (see <a href="#2.4.3">&sect;2.4.3</a>).
+Otherwise, all variables are initialized with <b>nil</b>.
+
+
+<p>
+A chunk is also a block (see <a href="#2.4.1">&sect;2.4.1</a>),
+and so local variables can be declared in a chunk outside any explicit block.
+The scope of such local variables extends until the end of the chunk.
+
+
+<p>
+The visibility rules for local variables are explained in <a href="#2.6">&sect;2.6</a>.

+
+<h2>2.5 - <a name="2.5">Expressions</a></h2>
+
+<p>
+The basic expressions in Lua are the following:
+
+<pre>
+	exp ::= prefixexp
+	exp ::= <b>nil</b> | <b>false</b> | <b>true</b>
+	exp ::= Number
+	exp ::= String
+	exp ::= function
+	exp ::= tableconstructor
+	exp ::= `<b>...</b>&acute;
+	exp ::= exp binop exp
+	exp ::= unop exp
+	prefixexp ::= var | functioncall | `<b>(</b>&acute; exp `<b>)</b>&acute;
+</pre>
+
+<p>
+Numbers and literal strings are explained in <a href="#2.1">&sect;2.1</a>;
+variables are explained in <a href="#2.3">&sect;2.3</a>;
+function definitions are explained in <a href="#2.5.9">&sect;2.5.9</a>;
+function calls are explained in <a href="#2.5.8">&sect;2.5.8</a>;
+table constructors are explained in <a href="#2.5.7">&sect;2.5.7</a>.
+Vararg expressions,
+denoted by three dots ('<code>...</code>'), can only be used when
+directly inside a vararg function;
+they are explained in <a href="#2.5.9">&sect;2.5.9</a>.
+
+
+<p>
+Binary operators comprise arithmetic operators (see <a href="#2.5.1">&sect;2.5.1</a>),
+relational operators (see <a href="#2.5.2">&sect;2.5.2</a>), logical operators (see <a href="#2.5.3">&sect;2.5.3</a>),
+and the concatenation operator (see <a href="#2.5.4">&sect;2.5.4</a>).
+Unary operators comprise the unary minus (see <a href="#2.5.1">&sect;2.5.1</a>),
+the unary <b>not</b> (see <a href="#2.5.3">&sect;2.5.3</a>),
+and the unary <em>length operator</em> (see <a href="#2.5.5">&sect;2.5.5</a>).
+
+
+<p>
+Both function calls and vararg expressions may result in multiple values.
+If the expression is used as a statement (see <a href="#2.4.6">&sect;2.4.6</a>)
+(only possible for function calls),
+then its return list is adjusted to zero elements,
+thus discarding all returned values.
+If the expression is used as the last (or the only) element
+of a list of expressions,
+then no adjustment is made
+(unless the call is enclosed in parentheses).
+In all other contexts,
+Lua adjusts the result list to one element,
+discarding all values except the first one.
+
+
+<p>
+Here are some examples:
+
+<pre>
+     f()                -- adjusted to 0 results
+     g(f(), x)          -- f() is adjusted to 1 result
+     g(x, f())          -- g gets x plus all results from f()
+     a,b,c = f(), x     -- f() is adjusted to 1 result (c gets nil)
+     a,b = ...          -- a gets the first vararg parameter, b gets
+                        -- the second (both a and b may get nil if there
+                        -- is no corresponding vararg parameter)
+     
+     a,b,c = x, f()     -- f() is adjusted to 2 results
+     a,b,c = f()        -- f() is adjusted to 3 results
+     return f()         -- returns all results from f()
+     return ...         -- returns all received vararg parameters
+     return x,y,f()     -- returns x, y, and all results from f()
+     {f()}              -- creates a list with all results from f()
+     {...}              -- creates a list with all vararg parameters
+     {f(), nil}         -- f() is adjusted to 1 result
+</pre>
+
+<p>
+An expression enclosed in parentheses always results in only one value.
+Thus,
+<code>(f(x,y,z))</code> is always a single value,
+even if <code>f</code> returns several values.
+(The value of <code>(f(x,y,z))</code> is the first value returned by <code>f</code>
+or <b>nil</b> if <code>f</code> does not return any values.)
+
+
+
+<h3>2.5.1 - <a name="2.5.1">Arithmetic Operators</a></h3><p>
+Lua supports the usual arithmetic operators:
+the binary <code>+</code> (addition),
+<code>-</code> (subtraction), <code>*</code> (multiplication),
+<code>/</code> (division), <code>%</code> (modulo), and <code>^</code> (exponentiation);
+and unary <code>-</code> (negation).
+If the operands are numbers, or strings that can be converted to
+numbers (see <a href="#2.2.1">&sect;2.2.1</a>),
+then all operations have the usual meaning.
+Exponentiation works for any exponent.
+For instance, <code>x^(-0.5)</code> computes the inverse of the square root of <code>x</code>.
+Modulo is defined as
+
+<pre>
+     a % b == a - math.floor(a/b)*b
+</pre><p>
+That is, it is the remainder of a division that rounds
+the quotient towards minus infinity.
+
+
+
+
+
+<h3>2.5.2 - <a name="2.5.2">Relational Operators</a></h3><p>
+The relational operators in Lua are
+
+<pre>
+     ==    ~=    &lt;     &gt;     &lt;=    &gt;=
+</pre><p>
+These operators always result in <b>false</b> or <b>true</b>.
+
+
+<p>
+Equality (<code>==</code>) first compares the type of its operands.
+If the types are different, then the result is <b>false</b>.
+Otherwise, the values of the operands are compared.
+Numbers and strings are compared in the usual way.
+Objects (tables, userdata, threads, and functions)
+are compared by <em>reference</em>:
+two objects are considered equal only if they are the <em>same</em> object.
+Every time you create a new object
+(a table, userdata, thread, or function),
+this new object is different from any previously existing object.
+
+
+<p>
+You can change the way that Lua compares tables and userdata 
+by using the "eq" metamethod (see <a href="#2.8">&sect;2.8</a>).
+
+
+<p>
+The conversion rules of <a href="#2.2.1">&sect;2.2.1</a>
+<em>do not</em> apply to equality comparisons.
+Thus, <code>"0"==0</code> evaluates to <b>false</b>,
+and <code>t[0]</code> and <code>t["0"]</code> denote different
+entries in a table.
+
+
+<p>
+The operator <code>~=</code> is exactly the negation of equality (<code>==</code>).
+
+
+<p>
+The order operators work as follows.
+If both arguments are numbers, then they are compared as such.
+Otherwise, if both arguments are strings,
+then their values are compared according to the current locale.
+Otherwise, Lua tries to call the "lt" or the "le"
+metamethod (see <a href="#2.8">&sect;2.8</a>).
+
+
+
+
+
+<h3>2.5.3 - <a name="2.5.3">Logical Operators</a></h3><p>
+The logical operators in Lua are
+<b>and</b>, <b>or</b>, and <b>not</b>.
+Like the control structures (see <a href="#2.4.4">&sect;2.4.4</a>),
+all logical operators consider both <b>false</b> and <b>nil</b> as false
+and anything else as true.
+
+
+<p>
+The negation operator <b>not</b> always returns <b>false</b> or <b>true</b>.
+The conjunction operator <b>and</b> returns its first argument
+if this value is <b>false</b> or <b>nil</b>;
+otherwise, <b>and</b> returns its second argument.
+The disjunction operator <b>or</b> returns its first argument
+if this value is different from <b>nil</b> and <b>false</b>;
+otherwise, <b>or</b> returns its second argument.
+Both <b>and</b> and <b>or</b> use short-cut evaluation;
+that is,
+the second operand is evaluated only if necessary.
+Here are some examples:
+
+<pre>
+     10 or 20            --&gt; 10
+     10 or error()       --&gt; 10
+     nil or "a"          --&gt; "a"
+     nil and 10          --&gt; nil
+     false and error()   --&gt; false
+     false and nil       --&gt; false
+     false or nil        --&gt; nil
+     10 and 20           --&gt; 20
+</pre><p>
+(In this manual,
+--> indicates the result of the preceding expression.)
+
+
+
+
+
+<h3>2.5.4 - <a name="2.5.4">Concatenation</a></h3><p>
+The string concatenation operator in Lua is
+denoted by two dots ('<code>..</code>').
+If both operands are strings or numbers, then they are converted to
+strings according to the rules mentioned in <a href="#2.2.1">&sect;2.2.1</a>.
+Otherwise, the "concat" metamethod is called (see <a href="#2.8">&sect;2.8</a>).
+
+
+
+
+
+<h3>2.5.5 - <a name="2.5.5">The Length Operator</a></h3>
+
+<p>
+The length operator is denoted by the unary operator <code>#</code>.
+The length of a string is its number of bytes
+(that is, the usual meaning of string length when each
+character is one byte).
+
+
+<p>
+The length of a table <code>t</code> is defined to be any
+integer index <code>n</code>
+such that <code>t[n]</code> is not <b>nil</b> and <code>t[n+1]</code> is <b>nil</b>;
+moreover, if <code>t[1]</code> is <b>nil</b>, <code>n</code> may be zero.
+For a regular array, with non-nil values from 1 to a given <code>n</code>,
+its length is exactly that <code>n</code>,
+the index of its last value.
+If the array has "holes"
+(that is, <b>nil</b> values between other non-nil values),
+then <code>#t</code> may be any of the indices that
+directly precedes a <b>nil</b> value
+(that is, it may consider any such <b>nil</b> value as the end of
+the array). 
+
+
+
+
+
+<h3>2.5.6 - <a name="2.5.6">Precedence</a></h3><p>
+Operator precedence in Lua follows the table below,
+from lower to higher priority:
+
+<pre>
+     or
+     and
+     &lt;     &gt;     &lt;=    &gt;=    ~=    ==
+     ..
+     +     -
+     *     /     %
+     not   #     - (unary)
+     ^
+</pre><p>
+As usual,
+you can use parentheses to change the precedences of an expression.
+The concatenation ('<code>..</code>') and exponentiation ('<code>^</code>')
+operators are right associative.
+All other binary operators are left associative.
+
+
+
+
+
+<h3>2.5.7 - <a name="2.5.7">Table Constructors</a></h3><p>
+Table constructors are expressions that create tables.
+Every time a constructor is evaluated, a new table is created.
+Constructors can be used to create empty tables,
+or to create a table and initialize some of its fields.
+The general syntax for constructors is
+
+<pre>
+	tableconstructor ::= `<b>{</b>&acute; [fieldlist] `<b>}</b>&acute;
+	fieldlist ::= field {fieldsep field} [fieldsep]
+	field ::= `<b>[</b>&acute; exp `<b>]</b>&acute; `<b>=</b>&acute; exp | Name `<b>=</b>&acute; exp | exp
+	fieldsep ::= `<b>,</b>&acute; | `<b>;</b>&acute;
+</pre>
+
+<p>
+Each field of the form <code>[exp1] = exp2</code> adds to the new table an entry
+with key <code>exp1</code> and value <code>exp2</code>.
+A field of the form <code>name = exp</code> is equivalent to
+<code>["name"] = exp</code>.
+Finally, fields of the form <code>exp</code> are equivalent to
+<code>[i] = exp</code>, where <code>i</code> are consecutive numerical integers,
+starting with 1.
+Fields in the other formats do not affect this counting.
+For example,
+
+<pre>
+     a = { [f(1)] = g; "x", "y"; x = 1, f(x), [30] = 23; 45 }
+</pre><p>
+is equivalent to
+
+<pre>
+     do
+       local t = {}
+       t[f(1)] = g
+       t[1] = "x"         -- 1st exp
+       t[2] = "y"         -- 2nd exp
+       t.x = 1            -- t["x"] = 1
+       t[3] = f(x)        -- 3rd exp
+       t[30] = 23
+       t[4] = 45          -- 4th exp
+       a = t
+     end
+</pre>
+
+<p>
+If the last field in the list has the form <code>exp</code>
+and the expression is a function call or a vararg expression,
+then all values returned by this expression enter the list consecutively
+(see <a href="#2.5.8">&sect;2.5.8</a>).
+To avoid this,
+enclose the function call (or the vararg expression)
+in parentheses (see <a href="#2.5">&sect;2.5</a>).
+
+
+<p>
+The field list may have an optional trailing separator,
+as a convenience for machine-generated code.
+
+
+
+
+
+<h3>2.5.8 - <a name="2.5.8">Function Calls</a></h3><p>
+A function call in Lua has the following syntax:
+
+<pre>
+	functioncall ::= prefixexp args
+</pre><p>
+In a function call,
+first prefixexp and args are evaluated.
+If the value of prefixexp has type <em>function</em>,
+then this function is called
+with the given arguments.
+Otherwise, the prefixexp "call" metamethod is called,
+having as first parameter the value of prefixexp,
+followed by the original call arguments
+(see <a href="#2.8">&sect;2.8</a>).
+
+
+<p>
+The form
+
+<pre>
+	functioncall ::= prefixexp `<b>:</b>&acute; Name args
+</pre><p>
+can be used to call "methods".
+A call <code>v:name(<em>args</em>)</code>
+is syntactic sugar for <code>v.name(v,<em>args</em>)</code>,
+except that <code>v</code> is evaluated only once.
+
+
+<p>
+Arguments have the following syntax:
+
+<pre>
+	args ::= `<b>(</b>&acute; [explist] `<b>)</b>&acute;
+	args ::= tableconstructor
+	args ::= String
+</pre><p>
+All argument expressions are evaluated before the call.
+A call of the form <code>f{<em>fields</em>}</code> is
+syntactic sugar for <code>f({<em>fields</em>})</code>;
+that is, the argument list is a single new table.
+A call of the form <code>f'<em>string</em>'</code>
+(or <code>f"<em>string</em>"</code> or <code>f[[<em>string</em>]]</code>)
+is syntactic sugar for <code>f('<em>string</em>')</code>;
+that is, the argument list is a single literal string.
+
+
+<p>
+As an exception to the free-format syntax of Lua,
+you cannot put a line break before the '<code>(</code>' in a function call.
+This restriction avoids some ambiguities in the language.
+If you write
+
+<pre>
+     a = f
+     (g).x(a)
+</pre><p>
+Lua would see that as a single statement, <code>a = f(g).x(a)</code>.
+So, if you want two statements, you must add a semi-colon between them.
+If you actually want to call <code>f</code>,
+you must remove the line break before <code>(g)</code>.
+
+
+<p>
+A call of the form <code>return</code> <em>functioncall</em> is called
+a <em>tail call</em>.
+Lua implements <em>proper tail calls</em>
+(or <em>proper tail recursion</em>):
+in a tail call,
+the called function reuses the stack entry of the calling function.
+Therefore, there is no limit on the number of nested tail calls that
+a program can execute.
+However, a tail call erases any debug information about the
+calling function.
+Note that a tail call only happens with a particular syntax,
+where the <b>return</b> has one single function call as argument;
+this syntax makes the calling function return exactly
+the returns of the called function.
+So, none of the following examples are tail calls:
+
+<pre>
+     return (f(x))        -- results adjusted to 1
+     return 2 * f(x)
+     return x, f(x)       -- additional results
+     f(x); return         -- results discarded
+     return x or f(x)     -- results adjusted to 1
+</pre>

+
+<h3>2.5.9 - <a name="2.5.9">Function Definitions</a></h3>
+
+<p>
+The syntax for function definition is
+
+<pre>
+	function ::= <b>function</b> funcbody
+	funcbody ::= `<b>(</b>&acute; [parlist] `<b>)</b>&acute; block <b>end</b>
+</pre>
+
+<p>
+The following syntactic sugar simplifies function definitions:
+
+<pre>
+	stat ::= <b>function</b> funcname funcbody
+	stat ::= <b>local</b> <b>function</b> Name funcbody
+	funcname ::= Name {`<b>.</b>&acute; Name} [`<b>:</b>&acute; Name]
+</pre><p>
+The statement
+
+<pre>
+     function f () <em>body</em> end
+</pre><p>
+translates to
+
+<pre>
+     f = function () <em>body</em> end
+</pre><p>
+The statement
+
+<pre>
+     function t.a.b.c.f () <em>body</em> end
+</pre><p>
+translates to
+
+<pre>
+     t.a.b.c.f = function () <em>body</em> end
+</pre><p>
+The statement
+
+<pre>
+     local function f () <em>body</em> end
+</pre><p>
+translates to
+
+<pre>
+     local f; f = function () <em>body</em> end
+</pre><p>
+<em>not</em> to
+
+<pre>
+     local f = function () <em>body</em> end
+</pre><p>
+(This only makes a difference when the body of the function
+contains references to <code>f</code>.)
+
+
+<p>
+A function definition is an executable expression,
+whose value has type <em>function</em>.
+When Lua pre-compiles a chunk,
+all its function bodies are pre-compiled too.
+Then, whenever Lua executes the function definition,
+the function is <em>instantiated</em> (or <em>closed</em>).
+This function instance (or <em>closure</em>)
+is the final value of the expression.
+Different instances of the same function
+may refer to different  external local variables
+and may have different environment tables.
+
+
+<p>
+Parameters act as local variables that are
+initialized with the argument values:
+
+<pre>
+	parlist ::= namelist [`<b>,</b>&acute; `<b>...</b>&acute;] | `<b>...</b>&acute;
+</pre><p>
+When a function is called,
+the list of arguments is adjusted to
+the length of the list of parameters,
+unless the function is a variadic or <em>vararg function</em>,
+which is
+indicated by three dots ('<code>...</code>') at the end of its parameter list.
+A vararg function does not adjust its argument list;
+instead, it collects all extra arguments and supplies them
+to the function through a <em>vararg expression</em>,
+which is also written as three dots.
+The value of this expression is a list of all actual extra arguments,
+similar to a function with multiple results.
+If a vararg expression is used inside another expression
+or in the middle of a list of expressions,
+then its return list is adjusted to one element.
+If the expression is used as the last element of a list of expressions,
+then no adjustment is made
+(unless the call is enclosed in parentheses).
+
+
+<p>
+As an example, consider the following definitions:
+
+<pre>
+     function f(a, b) end
+     function g(a, b, ...) end
+     function r() return 1,2,3 end
+</pre><p>
+Then, we have the following mapping from arguments to parameters and
+to the vararg expression:
+
+<pre>
+     CALL            PARAMETERS
+     
+     f(3)             a=3, b=nil
+     f(3, 4)          a=3, b=4
+     f(3, 4, 5)       a=3, b=4
+     f(r(), 10)       a=1, b=10
+     f(r())           a=1, b=2
+     
+     g(3)             a=3, b=nil, ... --&gt;  (nothing)
+     g(3, 4)          a=3, b=4,   ... --&gt;  (nothing)
+     g(3, 4, 5, 8)    a=3, b=4,   ... --&gt;  5  8
+     g(5, r())        a=5, b=1,   ... --&gt;  2  3
+</pre>
+
+<p>
+Results are returned using the <b>return</b> statement (see <a href="#2.4.4">&sect;2.4.4</a>).
+If control reaches the end of a function
+without encountering a <b>return</b> statement,
+then the function returns with no results.
+
+
+<p>
+The <em>colon</em> syntax
+is used for defining <em>methods</em>,
+that is, functions that have an implicit extra parameter <code>self</code>.
+Thus, the statement
+
+<pre>
+     function t.a.b.c:f (<em>params</em>) <em>body</em> end
+</pre><p>
+is syntactic sugar for
+
+<pre>
+     t.a.b.c.f = function (self, <em>params</em>) <em>body</em> end
+</pre>
+
+
+
+
+
+
+<h2>2.6 - <a name="2.6">Visibility Rules</a></h2>
+
+<p>
+
+Lua is a lexically scoped language.
+The scope of variables begins at the first statement <em>after</em>
+their declaration and lasts until the end of the innermost block that
+includes the declaration.
+Consider the following example:
+
+<pre>
+     x = 10                -- global variable
+     do                    -- new block
+       local x = x         -- new 'x', with value 10
+       print(x)            --&gt; 10
+       x = x+1
+       do                  -- another block
+         local x = x+1     -- another 'x'
+         print(x)          --&gt; 12
+       end
+       print(x)            --&gt; 11
+     end
+     print(x)              --&gt; 10  (the global one)
+</pre>
+
+<p>
+Notice that, in a declaration like <code>local x = x</code>,
+the new <code>x</code> being declared is not in scope yet,
+and so the second <code>x</code> refers to the outside variable.
+
+
+<p>
+Because of the lexical scoping rules,
+local variables can be freely accessed by functions
+defined inside their scope.
+A local variable used by an inner function is called
+an <em>upvalue</em>, or <em>external local variable</em>,
+inside the inner function.
+
+
+<p>
+Notice that each execution of a <b>local</b> statement
+defines new local variables.
+Consider the following example:
+
+<pre>
+     a = {}
+     local x = 20
+     for i=1,10 do
+       local y = 0
+       a[i] = function () y=y+1; return x+y end
+     end
+</pre><p>
+The loop creates ten closures
+(that is, ten instances of the anonymous function).
+Each of these closures uses a different <code>y</code> variable,
+while all of them share the same <code>x</code>.
+
+
+
+
+
+<h2>2.7 - <a name="2.7">Error Handling</a></h2>
+
+<p>
+Because Lua is an embedded extension language,
+all Lua actions start from C&nbsp;code in the host program
+calling a function from the Lua library (see <a href="#lua_pcall"><code>lua_pcall</code></a>).
+Whenever an error occurs during Lua compilation or execution,
+control returns to C,
+which can take appropriate measures
+(such as printing an error message).
+
+
+<p>
+Lua code can explicitly generate an error by calling the
+<a href="#pdf-error"><code>error</code></a> function.
+If you need to catch errors in Lua,
+you can use the <a href="#pdf-pcall"><code>pcall</code></a> function.
+
+
+
+
+
+<h2>2.8 - <a name="2.8">Metatables</a></h2>
+
+<p>
+Every value in Lua may have a <em>metatable</em>.
+This <em>metatable</em> is an ordinary Lua table
+that defines the behavior of the original value
+under certain special operations.
+You can change several aspects of the behavior
+of operations over a value by setting specific fields in its metatable.
+For instance, when a non-numeric value is the operand of an addition,
+Lua checks for a function in the field <code>"__add"</code> in its metatable.
+If it finds one,
+Lua calls this function to perform the addition.
+
+
+<p>
+We call the keys in a metatable <em>events</em>
+and the values <em>metamethods</em>.
+In the previous example, the event is <code>"add"</code> 
+and the metamethod is the function that performs the addition.
+
+
+<p>
+You can query the metatable of any value
+through the <a href="#pdf-getmetatable"><code>getmetatable</code></a> function.
+
+
+<p>
+You can replace the metatable of tables
+through the <a href="#pdf-setmetatable"><code>setmetatable</code></a>
+function.
+You cannot change the metatable of other types from Lua
+(except using the debug library);
+you must use the C&nbsp;API for that.
+
+
+<p>
+Tables and full userdata have individual metatables
+(although multiple tables and userdata can share their metatables);
+values of all other types share one single metatable per type.
+So, there is one single metatable for all numbers,
+one for all strings, etc.
+
+
+<p>
+A metatable may control how an object behaves in arithmetic operations,
+order comparisons, concatenation, length operation, and indexing.
+A metatable can also define a function to be called when a userdata
+is garbage collected.
+For each of these operations Lua associates a specific key
+called an <em>event</em>.
+When Lua performs one of these operations over a value,
+it checks whether this value has a metatable with the corresponding event.
+If so, the value associated with that key (the metamethod)
+controls how Lua will perform the operation.
+
+
+<p>
+Metatables control the operations listed next.
+Each operation is identified by its corresponding name.
+The key for each operation is a string with its name prefixed by
+two underscores, '<code>__</code>';
+for instance, the key for operation "add" is the
+string <code>"__add"</code>.
+The semantics of these operations is better explained by a Lua function
+describing how the interpreter executes the operation.
+
+
+<p>
+The code shown here in Lua is only illustrative;
+the real behavior is hard coded in the interpreter
+and it is much more efficient than this simulation.
+All functions used in these descriptions
+(<a href="#pdf-rawget"><code>rawget</code></a>, <a href="#pdf-tonumber"><code>tonumber</code></a>, etc.)
+are described in <a href="#5.1">&sect;5.1</a>.
+In particular, to retrieve the metamethod of a given object,
+we use the expression
+
+<pre>
+     metatable(obj)[event]
+</pre><p>
+This should be read as
+
+<pre>
+     rawget(getmetatable(obj) or {}, event)
+</pre><p>
+
+That is, the access to a metamethod does not invoke other metamethods,
+and the access to objects with no metatables does not fail
+(it simply results in <b>nil</b>).
+
+
+
+<ul>
+
+<li><b>"add":</b>
+the <code>+</code> operation.
+
+
+
+<p>
+The function <code>getbinhandler</code> below defines how Lua chooses a handler
+for a binary operation.
+First, Lua tries the first operand.
+If its type does not define a handler for the operation,
+then Lua tries the second operand.
+
+<pre>
+     function getbinhandler (op1, op2, event)
+       return metatable(op1)[event] or metatable(op2)[event]

+<h2>2.9 - <a name="2.9">Environments</a></h2>
+
+<p>
+Besides metatables,
+objects of types thread, function, and userdata
+have another table associated with them,
+called their <em>environment</em>.
+Like metatables, environments are regular tables and
+multiple objects can share the same environment.
+
+
+<p>
+Environments associated with userdata have no meaning for Lua.
+It is only a convenience feature for programmers to associate a table to
+a userdata.
+
+
+<p>
+Environments associated with threads are called
+<em>global environments</em>.
+They are used as the default environment for their threads and
+non-nested functions created by the thread
+(through <a href="#pdf-loadfile"><code>loadfile</code></a>, <a href="#pdf-loadstring"><code>loadstring</code></a> or <a href="#pdf-load"><code>load</code></a>)
+and can be directly accessed by C&nbsp;code (see <a href="#3.3">&sect;3.3</a>).
+
+
+<p>
+Environments associated with C&nbsp;functions can be directly
+accessed by C&nbsp;code (see <a href="#3.3">&sect;3.3</a>).
+They are used as the default environment for other C&nbsp;functions
+created by the function.
+
+
+<p>
+Environments associated with Lua functions are used to resolve
+all accesses to global variables within the function (see <a href="#2.3">&sect;2.3</a>).
+They are used as the default environment for other Lua functions
+created by the function.
+
+
+<p>
+You can change the environment of a Lua function or the
+running thread by calling <a href="#pdf-setfenv"><code>setfenv</code></a>.
+You can get the environment of a Lua function or the running thread
+by calling <a href="#pdf-getfenv"><code>getfenv</code></a>.
+To manipulate the environment of other objects
+(userdata, C&nbsp;functions, other threads) you must
+use the C&nbsp;API.
+
+
+
+
+
+<h2>2.10 - <a name="2.10">Garbage Collection</a></h2>
+
+<p>
+Lua performs automatic memory management.
+This means that
+you have to worry neither about allocating memory for new objects
+nor about freeing it when the objects are no longer needed.
+Lua manages memory automatically by running
+a <em>garbage collector</em> from time to time
+to collect all <em>dead objects</em>
+(that is, these objects that are no longer accessible from Lua).
+All objects in Lua are subject to automatic management:
+tables, userdata, functions, threads, and strings.
+
+
+<p>
+Lua implements an incremental mark-and-sweep collector.
+It uses two numbers to control its garbage-collection cycles:
+the <em>garbage-collector pause</em> and
+the <em>garbage-collector step multiplier</em>.
+
+
+<p>
+The garbage-collector pause
+controls how long the collector waits before starting a new cycle.
+Larger values make the collector less aggressive.
+Values smaller than 1 mean the collector will not wait to
+start a new cycle.
+A value of 2 means that the collector waits for the total memory in use
+to double before starting a new cycle.
+
+
+<p>
+The step multiplier
+controls the relative speed of the collector relative to
+memory allocation.
+Larger values make the collector more aggressive but also increase
+the size of each incremental step.
+Values smaller than 1 make the collector too slow and
+may result in  the collector never finishing a cycle.
+The default, 2, means that the collector runs at "twice"
+the speed of memory allocation.
+
+
+<p>
+You can change these numbers by calling <a href="#lua_gc"><code>lua_gc</code></a> in C
+or <a href="#pdf-collectgarbage"><code>collectgarbage</code></a> in Lua.
+Both get percentage points as arguments
+(so an argument of 100 means a real value of 1).
+With these functions you can also control 
+the collector directly (e.g., stop and restart it).
+
+
+
+<h3>2.10.1 - <a name="2.10.1">Garbage-Collection Metamethods</a></h3>
+
+<p>
+Using the C&nbsp;API,
+you can set garbage-collector metamethods for userdata (see <a href="#2.8">&sect;2.8</a>).
+These metamethods are also called <em>finalizers</em>.
+Finalizers allow you to coordinate Lua's garbage collection
+with external resource management
+(such as closing files, network or database connections,
+or freeing your own memory).
+
+
+<p>
+Garbage userdata with a field <code>__gc</code> in their metatables are not
+collected immediately by the garbage collector.
+Instead, Lua puts them in a list.
+After the collection,
+Lua does the equivalent of the following function
+for each userdata in that list:
+
+<pre>
+     function gc_event (udata)
+       local h = metatable(udata).__gc
+       if h then
+         h(udata)
+       end
+     end
+</pre>
+
+<p>
+At the end of each garbage-collection cycle,
+the finalizers for userdata are called in <em>reverse</em>
+order of their creation,
+among those collected in that cycle.
+That is, the first finalizer to be called is the one associated
+with the userdata created last in the program.
+The userdata itself is freed only in the next garbage-collection cycle.
+
+
+
+
+
+<h3>2.10.2 - <a name="2.10.2">Weak Tables</a></h3>
+
+<p>
+A <em>weak table</em> is a table whose elements are
+<em>weak references</em>.
+A weak reference is ignored by the garbage collector.
+In other words,
+if the only references to an object are weak references,
+then the garbage collector will collect this object.
+
+
+<p>
+A weak table can have weak keys, weak values, or both.
+A table with weak keys allows the collection of its keys,
+but prevents the collection of its values.
+A table with both weak keys and weak values allows the collection of
+both keys and values.
+In any case, if either the key or the value is collected,
+the whole pair is removed from the table.
+The weakness of a table is controlled by the
+<code>__mode</code> field of its metatable.
+If the <code>__mode</code> field is a string containing the character&nbsp;'<code>k</code>',
+the keys in the table are weak.
+If <code>__mode</code> contains '<code>v</code>',
+the values in the table are weak.
+
+
+<p>
+After you use a table as a metatable,
+you should not change the value of its field <code>__mode</code>.
+Otherwise, the weak behavior of the tables controlled by this
+metatable is undefined.
+
+
+
+
+
+
+
+<h2>2.11 - <a name="2.11">Coroutines</a></h2>
+
+<p>
+Lua supports coroutines,
+also called <em>collaborative multithreading</em>.
+A coroutine in Lua represents an independent thread of execution.
+Unlike threads in multithread systems, however,
+a coroutine only suspends its execution by explicitly calling
+a yield function.
+
+
+<p>
+You create a coroutine with a call to <a href="#pdf-coroutine.create"><code>coroutine.create</code></a>.
+Its sole argument is a function
+that is the main function of the coroutine.
+The <code>create</code> function only creates a new coroutine and
+returns a handle to it (an object of type <em>thread</em>);
+it does not start the coroutine execution.
+
+
+<p>
+When you first call <a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a>,
+passing as its first argument
+the thread returned by <a href="#pdf-coroutine.create"><code>coroutine.create</code></a>,
+the coroutine starts its execution,
+at the first line of its main function.
+Extra arguments passed to <a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a> are passed on
+to the coroutine main function.
+After the coroutine starts running,
+it runs until it terminates or <em>yields</em>.
+
+
+<p>
+A coroutine can terminate its execution in two ways:
+normally, when its main function returns
+(explicitly or implicitly, after the last instruction);
+and abnormally, if there is an unprotected error.
+In the first case, <a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a> returns <b>true</b>,
+plus any values returned by the coroutine main function.
+In case of errors, <a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a> returns <b>false</b>
+plus an error message.
+
+
+<p>
+A coroutine yields by calling <a href="#pdf-coroutine.yield"><code>coroutine.yield</code></a>.
+When a coroutine yields,
+the corresponding <a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a> returns immediately,
+even if the yield happens inside nested function calls
+(that is, not in the main function,
+but in a function directly or indirectly called by the main function).
+In the case of a yield, <a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a> also returns <b>true</b>,
+plus any values passed to <a href="#pdf-coroutine.yield"><code>coroutine.yield</code></a>.
+The next time you resume the same coroutine,
+it continues its execution from the point where it yielded,
+with the call to <a href="#pdf-coroutine.yield"><code>coroutine.yield</code></a> returning any extra
+arguments passed to <a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a>.
+
+
+<p>
+Like <a href="#pdf-coroutine.create"><code>coroutine.create</code></a>,
+the <a href="#pdf-coroutine.wrap"><code>coroutine.wrap</code></a> function also creates a coroutine,
+but instead of returning the coroutine itself,
+it returns a function that, when called, resumes the coroutine.
+Any arguments passed to this function
+go as extra arguments to <a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a>.
+<a href="#pdf-coroutine.wrap"><code>coroutine.wrap</code></a> returns all the values returned by <a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a>,
+except the first one (the boolean error code).
+Unlike <a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a>,
+<a href="#pdf-coroutine.wrap"><code>coroutine.wrap</code></a> does not catch errors;
+any error is propagated to the caller.
+
+
+<p>
+As an example,
+consider the following code:
+
+<pre>
+     function foo (a)
+       print("foo", a)
+       return coroutine.yield(2*a)
+     end
+     
+     co = coroutine.create(function (a,b)
+           print("co-body", a, b)
+           local r = foo(a+1)
+           print("co-body", r)
+           local r, s = coroutine.yield(a+b, a-b)
+           print("co-body", r, s)
+           return b, "end"
+     end)
+            
+     print("main", coroutine.resume(co, 1, 10))
+     print("main", coroutine.resume(co, "r"))
+     print("main", coroutine.resume(co, "x", "y"))
+     print("main", coroutine.resume(co, "x", "y"))
+</pre><p>
+When you run it, it produces the following output:
+
+<pre>
+     co-body 1       10
+     foo     2
+     
+     main    true    4
+     co-body r
+     main    true    11      -9
+     co-body x       y
+     main    true    10      end
+     main    false   cannot resume dead coroutine
+</pre>

+
+<h1>3 - <a name="3">The Application Program Interface</a></h1>
+
+<p>
+
+This section describes the C&nbsp;API for Lua, that is,
+the set of C&nbsp;functions available to the host program to communicate
+with Lua.
+All API functions and related types and constants
+are declared in the header file <a name="pdf-lua.h"><code>lua.h</code></a>.
+
+
+<p>
+Even when we use the term "function",
+any facility in the API may be provided as a macro instead.
+All such macros use each of their arguments exactly once
+(except for the first argument, which is always a Lua state),
+and so do not generate any hidden side-effects.
+
+
+<p>
+As in most C&nbsp;libraries,
+the Lua API functions do not check their arguments for validity or consistency.
+However, you can change this behavior by compiling Lua
+with a proper definition for the macro <a name="pdf-luai_apicheck"><code>luai_apicheck</code></a>,
+in file <code>luaconf.h</code>.
+
+
+
+<h2>3.1 - <a name="3.1">The Stack</a></h2>
+
+<p>
+Lua uses a <em>virtual stack</em> to pass values to and from C.
+Each element in this stack represents a Lua value
+(<b>nil</b>, number, string, etc.).
+
+
+<p>
+Whenever Lua calls C, the called function gets a new stack,
+which is independent of previous stacks and of stacks of
+C&nbsp;functions that are still active.
+This stack initially contains any arguments to the C&nbsp;function
+and it is where the C&nbsp;function pushes its results
+to be returned to the caller (see <a href="#lua_CFunction"><code>lua_CFunction</code></a>).
+
+
+<p>
+For convenience,
+most query operations in the API do not follow a strict stack discipline.
+Instead, they can refer to any element in the stack
+by using an <em>index</em>:
+A positive index represents an <em>absolute</em> stack position
+(starting at&nbsp;1);
+a negative index represents an <em>offset</em> relative to the top of the stack.
+More specifically, if the stack has <em>n</em> elements,
+then index&nbsp;1 represents the first element
+(that is, the element that was pushed onto the stack first)
+and
+index&nbsp;<em>n</em> represents the last element;
+index&nbsp;-1 also represents the last element
+(that is, the element at the&nbsp;top)
+and index <em>-n</em> represents the first element.
+We say that an index is <em>valid</em>
+if it lies between&nbsp;1 and the stack top
+(that is, if <code>1 &le; abs(index) &le; top</code>).
+ 
+
+
+
+
+
+<h2>3.2 - <a name="3.2">Stack Size</a></h2>
+
+<p>
+When you interact with Lua API,
+you are responsible for ensuring consistency.
+In particular,
+<em>you are responsible for controlling stack overflow</em>.
+You can use the function <a href="#lua_checkstack"><code>lua_checkstack</code></a>
+to grow the stack size.
+
+
+<p>
+Whenever Lua calls C,
+it ensures that at least <a name="pdf-LUA_MINSTACK"><code>LUA_MINSTACK</code></a> stack positions are available.
+<code>LUA_MINSTACK</code> is defined as 20,
+so that usually you do not have to worry about stack space
+unless your code has loops pushing elements onto the stack.
+
+
+<p>
+Most query functions accept as indices any value inside the
+available stack space, that is, indices up to the maximum stack size
+you have set through <a href="#lua_checkstack"><code>lua_checkstack</code></a>.
+Such indices are called <em>acceptable indices</em>.
+More formally, we define an <em>acceptable index</em>
+as follows:
+
+<pre>
+     (index &lt; 0 &amp;&amp; abs(index) &lt;= top) ||
+     (index &gt; 0 &amp;&amp; index &lt;= stackspace)
+</pre><p>
+Note that 0 is never an acceptable index.
+
+
+
+
+
+<h2>3.3 - <a name="3.3">Pseudo-Indices</a></h2>
+
+<p>
+Unless otherwise noted,
+any function that accepts valid indices can also be called with
+<em>pseudo-indices</em>,
+which represent some Lua values that are accessible to C&nbsp;code
+but which are not in the stack.
+Pseudo-indices are used to access the thread environment,
+the function environment,
+the registry,
+and the upvalues of a C&nbsp;function (see <a href="#3.4">&sect;3.4</a>).
+
+
+<p>
+The thread environment (where global variables live) is
+always at pseudo-index <a name="pdf-LUA_GLOBALSINDEX"><code>LUA_GLOBALSINDEX</code></a>.
+The environment of the running C&nbsp;function is always
+at pseudo-index <a name="pdf-LUA_ENVIRONINDEX"><code>LUA_ENVIRONINDEX</code></a>.
+
+
+<p>
+To access and change the value of global variables,
+you can use regular table operations over an environment table.
+For instance, to access the value of a global variable, do
+
+<pre>
+     lua_getfield(L, LUA_GLOBALSINDEX, varname);
+</pre>
+
+
+
+
+<h2>3.4 - <a name="3.4">C Closures</a></h2>
+
+<p>
+When a C&nbsp;function is created,
+it is possible to associate some values with it,
+thus creating a <em>C&nbsp;closure</em>;
+these values are called <em>upvalues</em> and are
+accessible to the function whenever it is called
+(see <a href="#lua_pushcclosure"><code>lua_pushcclosure</code></a>).
+
+
+<p>
+Whenever a C&nbsp;function is called,
+its upvalues are located at specific pseudo-indices.
+These pseudo-indices are produced by the macro
+<a name="lua_upvalueindex"><code>lua_upvalueindex</code></a>.
+The first value associated with a function is at position
+<code>lua_upvalueindex(1)</code>, and so on.
+Any access to <code>lua_upvalueindex(<em>n</em>)</code>,
+where <em>n</em> is greater than the number of upvalues of the
+current function,
+produces an acceptable (but invalid) index.
+
+
+
+
+
+<h2>3.5 - <a name="3.5">Registry</a></h2>
+
+<p>
+Lua provides a <em>registry</em>,
+a pre-defined table that can be used by any C&nbsp;code to
+store whatever Lua value it needs to store.
+This table is always located at pseudo-index
+<a name="pdf-LUA_REGISTRYINDEX"><code>LUA_REGISTRYINDEX</code></a>.
+Any C&nbsp;library can store data into this table,
+but it should take care to choose keys different from those used
+by other libraries, to avoid collisions.
+Typically, you should use as key a string containing your library name
+or a light userdata with the address of a C&nbsp;object in your code.
+
+
+<p>
+The integer keys in the registry are used by the reference mechanism,
+implemented by the auxiliary library,
+and therefore should not be used for other purposes.
+
+
+
+
+
+<h2>3.6 - <a name="3.6">Error Handling in C</a></h2>
+
+<p>
+Internally, Lua uses the C <code>longjmp</code> facility to handle errors.
+(You can also choose to use exceptions if you use C++;
+see file <code>luaconf.h</code>.)
+When Lua faces any error
+(such as memory allocation errors, type errors, syntax errors,
+and runtime errors)
+it <em>raises</em> an error;
+that is, it does a long jump.
+A <em>protected environment</em> uses <code>setjmp</code>
+to set a recover point;
+any error jumps to the most recent active recover point.
+
+
+<p>
+Most functions in the API may throw an error,
+for instance due to a memory allocation error.
+The documentation for each function indicates whether
+it can throw errors.
+
+
+<p>
+Inside a C&nbsp;function you can throw an error by calling <a href="#lua_error"><code>lua_error</code></a>.
+
+
+
+
+
+<h2>3.7 - <a name="3.7">Functions and Types</a></h2>
+
+<p>
+Here we list all functions and types from the C&nbsp;API in
+alphabetical order.
+Each function has an indicator like this:
+<span class="apii">[-o, +p, <em>x</em>]</span>
+
+
+<p>
+The first field, <code>o</code>,
+is how many elements the function pops from the stack.
+The second field, <code>p</code>,
+is how many elements the function pushes onto the stack.
+(Any function always pushes its results after popping its arguments.)
+A field in the form <code>x|y</code> means the function may push (or pop)
+<code>x</code> or <code>y</code> elements,
+depending on the situation;
+an interrogation mark '<code>?</code>' means that
+we cannot know how many elements the function pops/pushes
+by looking only at its arguments
+(e.g., they may depend on what is on the stack).
+The third field, <code>x</code>,
+tells whether the function may throw errors:
+'<code>-</code>' means the function never throws any error;
+'<code>m</code>' means the function may throw an error
+only due to not enough memory;
+'<code>e</code>' means the function may throw other kinds of errors;
+'<code>v</code>' means the function may throw an error on purpose.
+

+
+<p>
+The type of the memory-allocation function used by Lua states.
+The allocator function must provide a
+functionality similar to <code>realloc</code>,
+but not exactly the same.
+Its arguments are
+<code>ud</code>, an opaque pointer passed to <a href="#lua_newstate"><code>lua_newstate</code></a>;
+<code>ptr</code>, a pointer to the block being allocated/reallocated/freed;
+<code>osize</code>, the original size of the block;
+<code>nsize</code>, the new size of the block.
+<code>ptr</code> is <code>NULL</code> if and only if <code>osize</code> is zero.
+When <code>nsize</code> is zero, the allocator must return <code>NULL</code>;
+if <code>osize</code> is not zero,
+it should free the block pointed to by <code>ptr</code>.
+When <code>nsize</code> is not zero, the allocator returns <code>NULL</code>
+if and only if it cannot fill the request.
+When <code>nsize</code> is not zero and <code>osize</code> is zero,
+the allocator should behave like <code>malloc</code>.
+When <code>nsize</code> and <code>osize</code> are not zero,
+the allocator behaves like <code>realloc</code>.
+Lua assumes that the allocator never fails when
+<code>osize &gt;= nsize</code>.
+
+
+<p>
+Here is a simple implementation for the allocator function.
+It is used in the auxiliary library by <a href="#luaL_newstate"><code>luaL_newstate</code></a>.
+
+<pre>
+     static void *l_alloc (void *ud, void *ptr, size_t osize,
+                                                size_t nsize) {

+         return NULL;
+       }
+       else
+         return realloc(ptr, nsize);
+     }
+</pre><p>
+This code assumes
+that <code>free(NULL)</code> has no effect and that
+<code>realloc(NULL, size)</code> is equivalent to <code>malloc(size)</code>.
+ANSI&nbsp;C ensures both behaviors.

+Sets a new panic function and returns the old one.
+
+
+<p>
+If an error happens outside any protected environment,
+Lua calls a <em>panic function</em>

+thus exiting the host application.
+Your panic function may avoid this exit by

+To call a function you must use the following protocol:

+that is, the first argument is pushed first.
+Finally you call <a href="#lua_call"><code>lua_call</code></a>;
+<code>nargs</code> is the number of arguments that you pushed onto the stack.
+All arguments and the function value are popped from the stack

+The number of results is adjusted to <code>nresults</code>,

+In this case, <em>all</em> results from the function are pushed.
+Lua takes care that the returned values fit into the stack space.
+The function results are pushed onto the stack in direct order
+(the first result is pushed first),
+so that after the call the last result is on the top of the stack.
+
+
+<p>
+Any error inside the called function is propagated upwards
+(with a <code>longjmp</code>).
+
+
+<p>
+The following example shows how the host program may do the
+equivalent to this Lua code:
+
+<pre>
+     a = f("how", t.x, 14)
+</pre><p>
+Here it is in&nbsp;C:
+
+<pre>
+     lua_getfield(L, LUA_GLOBALSINDEX, "f"); /* function to be called */
+     lua_pushstring(L, "how");                        /* 1st argument */
+     lua_getfield(L, LUA_GLOBALSINDEX, "t");   /* table to be indexed */
+     lua_getfield(L, -1, "x");        /* push result of t.x (2nd arg) */
+     lua_remove(L, -2);                  /* remove 't' from the stack */
+     lua_pushinteger(L, 14);                          /* 3rd argument */
+     lua_call(L, 3, 1);     /* call 'f' with 3 arguments and 1 result */
+     lua_setfield(L, LUA_GLOBALSINDEX, "a");        /* set global 'a' */
+</pre><p>
+Note that the code above is "balanced":
+at its end, the stack is back to its original configuration.
+This is considered good programming practice.

+<pre>typedef int (*lua_CFunction) (lua_State *L);</pre>
+
+<p>
+Type for C&nbsp;functions.
+
+
+<p>
+In order to communicate properly with Lua,
+a C&nbsp;function must use the following protocol,
+which defines the way parameters and results are passed:
+a C&nbsp;function receives its arguments from Lua in its stack
+in direct order (the first argument is pushed first).
+So, when the function starts,
+<code>lua_gettop(L)</code> returns the number of arguments received by the function.
+The first argument (if any) is at index 1
+and its last argument is at index <code>lua_gettop(L)</code>.
+To return values to Lua, a C&nbsp;function just pushes them onto the stack,
+in direct order (the first result is pushed first),
+and returns the number of results.
+Any other value in the stack below the results will be properly
+discarded by Lua.
+Like a Lua function, a C&nbsp;function called by Lua can also return
+many results.
+
+
+<p>
+As an example, the following function receives a variable number
+of numerical arguments and returns their average and sum:
+
+<pre>
+     static int foo (lua_State *L) {
+       int n = lua_gettop(L);    /* number of arguments */
+       lua_Number sum = 0;
+       int i;
+       for (i = 1; i &lt;= n; i++) {
+         if (!lua_isnumber(L, i)) {
+           lua_pushstring(L, "incorrect argument");
+           lua_error(L);
+         }
+         sum += lua_tonumber(L, i);
+       }
+       lua_pushnumber(L, sum/n);        /* first result */
+       lua_pushnumber(L, sum);         /* second result */

+This function allocates a new block of memory with the given size,
+pushes onto the stack a new full userdata with the block address,
+and returns this address.
+
+
+<p>
+Userdata represent C&nbsp;values in Lua.
+A <em>full userdata</em> represents a block of memory.
+It is an object (like a table):
+you must create it, it can have its own metatable,
+and you can detect when it is being collected.
+A full userdata is only equal to itself (under raw equality).
+
+
+<p>
+When Lua collects a full userdata with a <code>gc</code> metamethod,
+Lua calls the metamethod and marks the userdata as finalized.
+When this userdata is collected again then
+Lua frees its corresponding memory.

+If there are no more elements in the table,

+However, if there is any error,

+Like <a href="#lua_call"><code>lua_call</code></a>,
+<a href="#lua_pcall"><code>lua_pcall</code></a> always removes the function

+
+
+<p>
+If <code>errfunc</code> is 0,

+Otherwise, <code>errfunc</code> is the stack index of an

+In case of runtime errors,
+this function will be called with the error message
+and its return value will be the message returned on the stack by <a href="#lua_pcall"><code>lua_pcall</code></a>.

+Typically, the error handler function is used to add more debug
+information to the error message, such as a stack traceback.

+Because functions in Lua are first-class values,

+some functions may be the value of multiple global variables,
+while others may be stored only in a table field.
+The <code>lua_getinfo</code> function checks how the function was

+Moreover, for line events, the field <code>currentline</code> is also set.
+To get the value of any other field in <code>ar</code>,
+the hook must call <a href="#lua_getinfo"><code>lua_getinfo</code></a>.
+For return events, <code>event</code> may be <code>LUA_HOOKRET</code>,

+<li><b>The call hook:</b> is called when the interpreter calls a function.
+The hook is called just after Lua enters the new function,
+before the function gets its arguments.
+</li>

+<h1>4 - <a name="4">The Auxiliary Library</a></h1>
+
+<p>
+
+The <em>auxiliary library</em> provides several convenient functions
+to interface C with Lua.
+While the basic API provides the primitive functions for all 
+interactions between C and Lua,
+the auxiliary library provides higher-level functions for some
+common tasks.
+
+
+<p>
+All functions from the auxiliary library
+are defined in header file <code>lauxlib.h</code> and
+have a prefix <code>luaL_</code>.
+
+
+<p>
+All functions in the auxiliary library are built on
+top of the basic API,
+and so they provide nothing that cannot be done with this API.
+
+
+<p>
+Several functions in the auxiliary library are used to
+check C&nbsp;function arguments.
+Their names are always <code>luaL_check*</code> or <code>luaL_opt*</code>.
+All of these functions throw an error if the check is not satisfied.
+Because the error message is formatted for arguments
+(e.g., "<code>bad argument #1</code>"),
+you should not use these functions for other stack values.
+
+
+
+<h2>4.1 - <a name="4.1">Functions and Types</a></h2>
+
+<p>
+Here we list all functions and types from the auxiliary library
+in alphabetical order.

+
+<p>
+This function never returns,

+
+
+
+
+
+<hr><h3><a name="luaL_Buffer"><code>luaL_Buffer</code></a></h3>
+<pre>typedef struct luaL_Buffer luaL_Buffer;</pre>
+
+<p>
+Type for a <em>string buffer</em>.
+
+
+<p>
+A string buffer allows C&nbsp;code to build Lua strings piecemeal.
+Its pattern of use is as follows:
+
+<ul>
+
+<li>First you declare a variable <code>b</code> of type <a href="#luaL_Buffer"><code>luaL_Buffer</code></a>.</li>
+
+<li>Then you initialize it with a call <code>luaL_buffinit(L, &amp;b)</code>.</li>
+
+<li>
+Then you add string pieces to the buffer calling any of
+the <code>luaL_add*</code> functions.
+</li>
+
+<li>
+You finish by calling <code>luaL_pushresult(&amp;b)</code>.
+This call leaves the final string on the top of the stack.
+</li>
+
+</ul>
+
+<p>
+During its normal operation,
+a string buffer uses a variable number of stack slots.
+So, while using a buffer, you cannot assume that you know where
+the top of the stack is.
+You can use the stack between successive calls to buffer operations
+as long as that use is balanced;
+that is,
+when you call a buffer operation,
+the stack is at the same level
+it was immediately after the previous buffer operation.
+(The only exception to this rule is <a href="#luaL_addvalue"><code>luaL_addvalue</code></a>.)
+After calling <a href="#luaL_pushresult"><code>luaL_pushresult</code></a> the stack is back to its
+level when the buffer was initialized,
+plus the final string on its top.

+
+
+<p>
+If the object at index <code>obj</code> has a metatable and this
+metatable has a field <code>e</code>,
+this function calls this field and passes the object as its only argument.
+In this case this function returns 1 and pushes onto the

+<h1>5 - <a name="5">Standard Libraries</a></h1>
+
+<p>
+The standard Lua libraries provide useful functions
+that are implemented directly through the C&nbsp;API.
+Some of these functions provide essential services to the language
+(e.g., <a href="#pdf-type"><code>type</code></a> and <a href="#pdf-getmetatable"><code>getmetatable</code></a>);
+others provide access to "outside" services (e.g., I/O);
+and others could be implemented in Lua itself,
+but are quite useful or have critical performance requirements that
+deserve an implementation in C (e.g., <a href="#pdf-table.sort"><code>table.sort</code></a>).
+
+
+<p>
+All libraries are implemented through the official C&nbsp;API
+and are provided as separate C&nbsp;modules.
+Currently, Lua has the following standard libraries:
+
+<ul>
+
+<li>basic library;</li>
+
+<li>package library;</li>
+
+<li>string manipulation;</li>
+
+<li>table manipulation;</li>
+
+<li>mathematical functions (sin, log, etc.);</li>
+
+<li>input and output;</li>
+
+<li>operating system facilities;</li>
+
+<li>debug facilities.</li>
+
+</ul><p>
+Except for the basic and package libraries,
+each library provides all its functions as fields of a global table
+or as methods of its objects.
+
+
+<p>
+To have access to these libraries,
+the C&nbsp;host program should call the <a href="#luaL_openlibs"><code>luaL_openlibs</code></a> function,
+which opens all standard libraries.
+Alternatively,
+it can open them individually by calling
+<a name="pdf-luaopen_base"><code>luaopen_base</code></a> (for the basic library),
+<a name="pdf-luaopen_package"><code>luaopen_package</code></a> (for the package library),
+<a name="pdf-luaopen_string"><code>luaopen_string</code></a> (for the string library),
+<a name="pdf-luaopen_table"><code>luaopen_table</code></a> (for the table library),
+<a name="pdf-luaopen_math"><code>luaopen_math</code></a> (for the mathematical library),
+<a name="pdf-luaopen_io"><code>luaopen_io</code></a> (for the I/O library),
+<a name="pdf-luaopen_os"><code>luaopen_os</code></a> (for the Operating System library),
+and <a name="pdf-luaopen_debug"><code>luaopen_debug</code></a> (for the debug library).
+These functions are declared in <a name="pdf-lualib.h"><code>lualib.h</code></a>
+and should not be called directly:
+you must call them like any other Lua C&nbsp;function,
+e.g., by using <a href="#lua_call"><code>lua_call</code></a>.
+
+
+
+<h2>5.1 - <a name="5.1">Basic Functions</a></h2>
+
+<p>
+The basic library provides some core functions to Lua.
+If you do not include this library in your application,
+you should check carefully whether you need to provide 
+implementations for some of its facilities.
+
+
+<p>
+<hr><h3><a name="pdf-assert"><code>assert (v [, message])</code></a></h3>
+Issues an  error when
+the value of its argument <code>v</code> is false (i.e., <b>nil</b> or <b>false</b>);
+otherwise, returns all its arguments.
+<code>message</code> is an error message;
+when absent, it defaults to "assertion failed!"
+
+
+
+
+<p>
+<hr><h3><a name="pdf-collectgarbage"><code>collectgarbage (opt [, arg])</code></a></h3>
+
+
+<p>
+This function is a generic interface to the garbage collector.
+It performs different functions according to its first argument, <code>opt</code>:
+
+<ul>
+
+<li><b>"stop":</b>
+stops the garbage collector.
+</li>
+
+<li><b>"restart":</b>
+restarts the garbage collector.
+</li>
+
+<li><b>"collect":</b>
+performs a full garbage-collection cycle.
+</li>
+
+<li><b>"count":</b>
+returns the total memory in use by Lua (in Kbytes).
+</li>
+
+<li><b>"step":</b>
+performs a garbage-collection step.
+The step "size" is controlled by <code>arg</code>
+(larger values mean more steps) in a non-specified way.
+If you want to control the step size
+you must experimentally tune the value of <code>arg</code>.
+Returns <b>true</b> if the step finished a collection cycle.
+</li>
+
+<li><b>"setpause":</b>
+sets <code>arg</code>/100 as the new value for the <em>pause</em> of
+the collector (see <a href="#2.10">&sect;2.10</a>).
+</li>
+
+<li><b>"setstepmul":</b>
+sets <code>arg</code>/100 as the new value for the <em>step multiplier</em> of
+the collector (see <a href="#2.10">&sect;2.10</a>).
+</li>
+
+</ul>
+
+
+
+<p>
+<hr><h3><a name="pdf-dofile"><code>dofile (filename)</code></a></h3>
+Opens the named file and executes its contents as a Lua chunk.
+When called without arguments,
+<code>dofile</code> executes the contents of the standard input (<code>stdin</code>).
+Returns all values returned by the chunk.
+In case of errors, <code>dofile</code> propagates the error
+to its caller (that is, <code>dofile</code> does not run in protected mode).
+
+
+
+
+<p>
+<hr><h3><a name="pdf-error"><code>error (message [, level])</code></a></h3>
+Terminates the last protected function called
+and returns <code>message</code> as the error message.
+Function <code>error</code> never returns.
+
+
+<p>
+Usually, <code>error</code> adds some information about the error position
+at the beginning of the message.
+The <code>level</code> argument specifies how to get the error position.
+With level&nbsp;1 (the default), the error position is where the
+<code>error</code> function was called.
+Level&nbsp;2 points the error to where the function
+that called <code>error</code> was called; and so on.
+Passing a level&nbsp;0 avoids the addition of error position information
+to the message.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-_G"><code>_G</code></a></h3>
+A global variable (not a function) that
+holds the global environment (that is, <code>_G._G = _G</code>).
+Lua itself does not use this variable;
+changing its value does not affect any environment,
+nor vice-versa.
+(Use <a href="#pdf-setfenv"><code>setfenv</code></a> to change environments.)
+
+
+
+
+<p>
+<hr><h3><a name="pdf-getfenv"><code>getfenv ([f])</code></a></h3>
+Returns the current environment in use by the function.
+<code>f</code> can be a Lua function or a number
+that specifies the function at that stack level:
+Level&nbsp;1 is the function calling <code>getfenv</code>.
+If the given function is not a Lua function,
+or if <code>f</code> is 0,
+<code>getfenv</code> returns the global environment.
+The default for <code>f</code> is 1.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-getmetatable"><code>getmetatable (object)</code></a></h3>
+
+
+<p>
+If <code>object</code> does not have a metatable, returns <b>nil</b>.
+Otherwise,
+if the object's metatable has a <code>"__metatable"</code> field,
+returns the associated value.
+Otherwise, returns the metatable of the given object.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-ipairs"><code>ipairs (t)</code></a></h3>
+

+so that the construction
+
+<pre>
+     for i,v in ipairs(t) do <em>body</em> end
+</pre><p>

+
+
+
+<p>
+<hr><h3><a name="pdf-load"><code>load (func [, chunkname])</code></a></h3>
+
+
+<p>
+Loads a chunk using function <code>func</code> to get its pieces.
+Each call to <code>func</code> must return a string that concatenates
+with previous results.
+A return of <b>nil</b> (or no value) signals the end of the chunk.
+
+
+<p>
+If there are no errors, 
+returns the compiled chunk as a function;
+otherwise, returns <b>nil</b> plus the error message.
+The environment of the returned function is the global environment.
+
+
+<p>
+<code>chunkname</code> is used as the chunk name for error messages
+and debug information.
+When absent,
+it defaults to "<code>=(load)</code>".
+
+
+
+
+<p>
+<hr><h3><a name="pdf-loadfile"><code>loadfile ([filename])</code></a></h3>
+
+
+<p>
+Similar to <a href="#pdf-load"><code>load</code></a>,

+or from the standard input,
+if no file name is given.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-loadstring"><code>loadstring (string [, chunkname])</code></a></h3>
+
+
+<p>
+Similar to <a href="#pdf-load"><code>load</code></a>,
+but gets the chunk from the given string.
+
+
+<p>
+To load and run a given string, use the idiom
+
+<pre>
+     assert(loadstring(s))()

+
+
+<p>
+<hr><h3><a name="pdf-next"><code>next (table [, index])</code></a></h3>
+
+
+<p>
+Allows a program to traverse all fields of a table.
+Its first argument is a table and its second argument
+is an index in this table.
+<code>next</code> returns the next index of the table
+and its associated value.
+When called with <b>nil</b> as its second argument,
+<code>next</code> returns an initial index
+and its associated value.
+When called with the last index,
+or with <b>nil</b> in an empty table,
+<code>next</code> returns <b>nil</b>.
+If the second argument is absent, then it is interpreted as <b>nil</b>.
+In particular,
+you can use <code>next(t)</code> to check whether a table is empty.
+
+
+<p>
+The order in which the indices are enumerated is not specified,
+<em>even for numeric indices</em>.
+(To traverse a table in numeric order,
+use a numerical <b>for</b> or the <a href="#pdf-ipairs"><code>ipairs</code></a> function.)
+
+
+<p>
+The behavior of <code>next</code> is <em>undefined</em> if,
+during the traversal,
+you assign any value to a non-existent field in the table.
+You may however modify existing fields.
+In particular, you may clear existing fields.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-pairs"><code>pairs (t)</code></a></h3>
+
+
+<p>
+Returns three values: the <a href="#pdf-next"><code>next</code></a> function, the table <code>t</code>, and <b>nil</b>,
+so that the construction
+
+<pre>
+     for k,v in pairs(t) do <em>body</em> end
+</pre><p>
+will iterate over all key&ndash;value pairs of table <code>t</code>.
+

+See function <a href="#pdf-next"><code>next</code></a> for the caveats of modifying
+the table during its traversal.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-pcall"><code>pcall (f, arg1, &middot;&middot;&middot;)</code></a></h3>
+
+
+<p>
+Calls function <code>f</code> with
+the given arguments in <em>protected mode</em>.
+This means that any error inside&nbsp;<code>f</code> is not propagated;
+instead, <code>pcall</code> catches the error
+and returns a status code.
+Its first result is the status code (a boolean),
+which is true if the call succeeds without errors.
+In such case, <code>pcall</code> also returns all results from the call,
+after this first result.
+In case of any error, <code>pcall</code> returns <b>false</b> plus the error message.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-print"><code>print (&middot;&middot;&middot;)</code></a></h3>
+Receives any number of arguments,
+and prints their values to <code>stdout</code>,
+using the <a href="#pdf-tostring"><code>tostring</code></a> function to convert them to strings.
+<code>print</code> is not intended for formatted output,

+<hr><h3><a name="pdf-tonumber"><code>tonumber (e [, base])</code></a></h3>
+Tries to convert its argument to a number.
+If the argument is already a number or a string convertible
+to a number, then <code>tonumber</code> returns this number;
+otherwise, it returns <b>nil</b>.
+
+
+<p>
+An optional argument specifies the base to interpret the numeral.
+The base may be any integer between 2 and 36, inclusive.
+In bases above&nbsp;10, the letter '<code>A</code>' (in either upper or lower case)
+represents&nbsp;10, '<code>B</code>' represents&nbsp;11, and so forth,
+with '<code>Z</code>' representing 35.
+In base 10 (the default), the number may have a decimal part,

+
+
+<p>
+<code>xpcall</code> calls function <code>f</code> in protected mode,

+Any error inside <code>f</code> is not propagated;
+instead, <code>xpcall</code> catches the error,
+calls the <code>err</code> function with the original error object,
+and returns a status code.
+Its first result is the status code (a boolean),
+which is true if the call succeeds without errors.
+In this case, <code>xpcall</code> also returns all results from the call,
+after this first result.
+In case of any error,
+<code>xpcall</code> returns <b>false</b> plus the result from <code>err</code>.

+
+<h2>5.3 - <a name="5.3">Modules</a></h2>
+
+<p>
+The package library provides basic
+facilities for loading and building modules in Lua.
+It exports two of its functions directly in the global environment:
+<a href="#pdf-require"><code>require</code></a> and <a href="#pdf-module"><code>module</code></a>.
+Everything else is exported in a table <a name="pdf-package"><code>package</code></a>.
+
+
+<p>
+<hr><h3><a name="pdf-module"><code>module (name [, &middot;&middot;&middot;])</code></a></h3>
+
+
+<p>
+Creates a module.
+If there is a table in <code>package.loaded[name]</code>,
+this table is the module.
+Otherwise, if there is a global table <code>t</code> with the given name,
+this table is the module.
+Otherwise creates a new table <code>t</code> and
+sets it as the value of the global <code>name</code> and
+the value of <code>package.loaded[name]</code>.
+This function also initializes <code>t._NAME</code> with the given name,
+<code>t._M</code> with the module (<code>t</code> itself),
+and <code>t._PACKAGE</code> with the package name
+(the full module name minus last component; see below).
+Finally, <code>module</code> sets <code>t</code> as the new environment
+of the current function and the new value of <code>package.loaded[name]</code>,
+so that <a href="#pdf-require"><code>require</code></a> returns <code>t</code>.
+
+
+<p>
+If <code>name</code> is a compound name
+(that is, one with components separated by dots),
+<code>module</code> creates (or reuses, if they already exist)
+tables for each component.
+For instance, if <code>name</code> is <code>a.b.c</code>,
+then <code>module</code> stores the module table in field <code>c</code> of
+field <code>b</code> of global <code>a</code>.
+
+
+<p>
+This function may receive optional <em>options</em> after
+the module name,
+where each option is a function to be applied over the module.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-require"><code>require (modname)</code></a></h3>
+
+
+<p>
+Loads the given module.
+The function starts by looking into the <a href="#pdf-package.loaded"><code>package.loaded</code></a> table
+to determine whether <code>modname</code> is already loaded.
+If it is, then <code>require</code> returns the value stored
+at <code>package.loaded[modname]</code>.
+Otherwise, it tries to find a <em>loader</em> for the module.
+
+
+<p>
+To find a loader,
+<code>require</code> is guided by the <a href="#pdf-package.loaders"><code>package.loaders</code></a> array.
+By changing this array,
+we can change how <code>require</code> looks for a module.
+The following explanation is based on the default configuration
+for <a href="#pdf-package.loaders"><code>package.loaders</code></a>.
+
+
+<p>
+First <code>require</code> queries <code>package.preload[modname]</code>.
+If it has a value,
+this value (which should be a function) is the loader.
+Otherwise <code>require</code> searches for a Lua loader using the
+path stored in <a href="#pdf-package.path"><code>package.path</code></a>.
+If that also fails, it searches for a C&nbsp;loader using the
+path stored in <a href="#pdf-package.cpath"><code>package.cpath</code></a>.
+If that also fails,
+it tries an <em>all-in-one</em> loader (see <a href="#pdf-package.loaders"><code>package.loaders</code></a>).
+
+
+<p>
+Once a loader is found,
+<code>require</code> calls the loader with a single argument, <code>modname</code>.
+If the loader returns any value,
+<code>require</code> assigns the returned value to <code>package.loaded[modname]</code>.
+If the loader returns no value and
+has not assigned any value to <code>package.loaded[modname]</code>,
+then <code>require</code> assigns <b>true</b> to this entry.
+In any case, <code>require</code> returns the
+final value of <code>package.loaded[modname]</code>.
+
+
+<p>
+If there is any error loading or running the module,
+or if it cannot find any loader for the module,
+then <code>require</code> signals an error. 
+
+
+
+
+<p>
+<hr><h3><a name="pdf-package.cpath"><code>package.cpath</code></a></h3>
+
+
+<p>
+The path used by <a href="#pdf-require"><code>require</code></a> to search for a C&nbsp;loader.
+
+
+<p>
+Lua initializes the C&nbsp;path <a href="#pdf-package.cpath"><code>package.cpath</code></a> in the same way
+it initializes the Lua path <a href="#pdf-package.path"><code>package.path</code></a>,
+using the environment variable <a name="pdf-LUA_CPATH"><code>LUA_CPATH</code></a>
+or a default path defined in <code>luaconf.h</code>.
+
+
+
+
+<p>
+
+<hr><h3><a name="pdf-package.loaded"><code>package.loaded</code></a></h3>
+
+
+<p>
+A table used by <a href="#pdf-require"><code>require</code></a> to control which
+modules are already loaded.
+When you require a module <code>modname</code> and
+<code>package.loaded[modname]</code> is not false,
+<a href="#pdf-require"><code>require</code></a> simply returns the value stored there.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-package.loaders"><code>package.loaders</code></a></h3>
+
+
+<p>
+A table used by <a href="#pdf-require"><code>require</code></a> to control how to load modules.
+
+
+<p>
+Each entry in this table is a <em>searcher function</em>.
+When looking for a module,
+<a href="#pdf-require"><code>require</code></a> calls each of these searchers in ascending order,
+with the module name (the argument given to <a href="#pdf-require"><code>require</code></a>) as its
+sole parameter.
+The function may return another function (the module <em>loader</em>)
+or a string explaining why it did not find that module
+(or <b>nil</b> if it has nothing to say).
+Lua initializes this table with four functions.
+
+
+<p>
+The first searcher simply looks for a loader in the
+<a href="#pdf-package.preload"><code>package.preload</code></a> table.
+
+
+<p>
+The second searcher looks for a loader as a Lua library,
+using the path stored at <a href="#pdf-package.path"><code>package.path</code></a>.
+A path is a sequence of <em>templates</em> separated by semicolons.
+For each template,
+the searcher will change each interrogation
+mark in the template by <code>filename</code>,
+which is the module name with each dot replaced by a
+"directory separator" (such as "<code>/</code>" in Unix);
+then it will try to open the resulting file name.
+So, for instance, if the Lua path is the string
+
+<pre>
+     "./?.lua;./?.lc;/usr/local/?/init.lua"
+</pre><p>
+the search for a Lua file for module <code>foo</code>
+will try to open the files
+<code>./foo.lua</code>, <code>./foo.lc</code>, and
+<code>/usr/local/foo/init.lua</code>, in that order.
+
+
+<p>
+The third searcher looks for a loader as a C&nbsp;library,
+using the path given by the variable <a href="#pdf-package.cpath"><code>package.cpath</code></a>.
+For instance,
+if the C&nbsp;path is the string
+
+<pre>
+     "./?.so;./?.dll;/usr/local/?/init.so"
+</pre><p>
+the searcher for module <code>foo</code>
+will try to open the files <code>./foo.so</code>, <code>./foo.dll</code>,
+and <code>/usr/local/foo/init.so</code>, in that order.
+Once it finds a C&nbsp;library,
+this searcher first uses a dynamic link facility to link the
+application with the library.
+Then it tries to find a C&nbsp;function inside the library to
+be used as the loader.
+The name of this C&nbsp;function is the string "<code>luaopen_</code>"
+concatenated with a copy of the module name where each dot
+is replaced by an underscore.
+Moreover, if the module name has a hyphen,
+its prefix up to (and including) the first hyphen is removed.
+For instance, if the module name is <code>a.v1-b.c</code>,
+the function name will be <code>luaopen_b_c</code>.
+
+
+<p>
+The fourth searcher tries an <em>all-in-one loader</em>.
+It searches the C&nbsp;path for a library for
+the root name of the given module.
+For instance, when requiring <code>a.b.c</code>,
+it will search for a C&nbsp;library for <code>a</code>.
+If found, it looks into it for an open function for
+the submodule;
+in our example, that would be <code>luaopen_a_b_c</code>.
+With this facility, a package can pack several C&nbsp;submodules
+into one single library,
+with each submodule keeping its original open function.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-package.loadlib"><code>package.loadlib (libname, funcname)</code></a></h3>
+
+
+<p>
+Dynamically links the host program with the C&nbsp;library <code>libname</code>.
+Inside this library, looks for a function <code>funcname</code>
+and returns this function as a C&nbsp;function.
+(So, <code>funcname</code> must follow the protocol (see <a href="#lua_CFunction"><code>lua_CFunction</code></a>)).
+
+
+<p>
+This is a low-level function.
+It completely bypasses the package and module system.
+Unlike <a href="#pdf-require"><code>require</code></a>,
+it does not perform any path searching and
+does not automatically adds extensions.
+<code>libname</code> must be the complete file name of the C&nbsp;library,
+including if necessary a path and extension.
+<code>funcname</code> must be the exact name exported by the C&nbsp;library
+(which may depend on the C&nbsp;compiler and linker used).
+
+
+<p>
+This function is not supported by ANSI C.
+As such, it is only available on some platforms
+(Windows, Linux, Mac OS X, Solaris, BSD,
+plus other Unix systems that support the <code>dlfcn</code> standard).
+
+
+
+
+<p>
+<hr><h3><a name="pdf-package.path"><code>package.path</code></a></h3>
+
+
+<p>
+The path used by <a href="#pdf-require"><code>require</code></a> to search for a Lua loader.
+
+
+<p>
+At start-up, Lua initializes this variable with
+the value of the environment variable <a name="pdf-LUA_PATH"><code>LUA_PATH</code></a> or
+with a default path defined in <code>luaconf.h</code>,
+if the environment variable is not defined.
+Any "<code>;;</code>" in the value of the environment variable
+is replaced by the default path.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-package.preload"><code>package.preload</code></a></h3>
+
+
+<p>
+A table to store loaders for specific modules
+(see <a href="#pdf-require"><code>require</code></a>).
+
+
+
+
+<p>
+<hr><h3><a name="pdf-package.seeall"><code>package.seeall (module)</code></a></h3>
+
+
+<p>
+Sets a metatable for <code>module</code> with

+
+<h2>5.4 - <a name="5.4">String Manipulation</a></h2>
+
+<p>
+This library provides generic functions for string manipulation,
+such as finding and extracting substrings, and pattern matching.
+When indexing a string in Lua, the first character is at position&nbsp;1
+(not at&nbsp;0, as in C).
+Indices are allowed to be negative and are interpreted as indexing backwards,
+from the end of the string.
+Thus, the last character is at position -1, and so on.
+
+
+<p>
+The string library provides all its functions inside the table
+<a name="pdf-string"><code>string</code></a>.
+It also sets a metatable for strings
+where the <code>__index</code> field points to the <code>string</code> table.
+Therefore, you can use the string functions in object-oriented style.
+For instance, <code>string.byte(s, i)</code>
+can be written as <code>s:byte(i)</code>.
+
+
+<p>
+<hr><h3><a name="pdf-string.byte"><code>string.byte (s [, i [, j]])</code></a></h3>
+Returns the internal numerical codes of the characters <code>s[i]</code>,
+<code>s[i+1]</code>, &middot;&middot;&middot;, <code>s[j]</code>.
+The default value for <code>i</code> is&nbsp;1;
+the default value for <code>j</code> is&nbsp;<code>i</code>.
+
+
+<p>
+Note that numerical codes are not necessarily portable across platforms.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-string.char"><code>string.char (&middot;&middot;&middot;)</code></a></h3>
+Receives zero or more integers.
+Returns a string with length equal to the number of arguments,
+in which each character has the internal numerical code equal
+to its corresponding argument.
+
+
+<p>
+Note that numerical codes are not necessarily portable across platforms.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-string.dump"><code>string.dump (function)</code></a></h3>
+
+
+<p>
+Returns a string containing a binary representation of the given function,
+so that a later <a href="#pdf-loadstring"><code>loadstring</code></a> on this string returns
+a copy of the function.
+<code>function</code> must be a Lua function without upvalues.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-string.find"><code>string.find (s, pattern [, init [, plain]])</code></a></h3>
+Looks for the first match of
+<code>pattern</code> in the string <code>s</code>.
+If it finds a match, then <code>find</code> returns the indices of&nbsp;<code>s</code>
+where this occurrence starts and ends;
+otherwise, it returns <b>nil</b>.
+A third, optional numerical argument <code>init</code> specifies
+where to start the search;
+its default value is&nbsp;1 and may be negative.
+A value of <b>true</b> as a fourth, optional argument <code>plain</code>
+turns off the pattern matching facilities,
+so the function does a plain "find substring" operation,
+with no characters in <code>pattern</code> being considered "magic".
+Note that if <code>plain</code> is given, then <code>init</code> must be given as well.
+
+
+<p>
+If the pattern has captures,
+then in a successful match
+the captured values are also returned,
+after the two indices.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-string.format"><code>string.format (formatstring, &middot;&middot;&middot;)</code></a></h3>
+Returns a formatted version of its variable number of arguments
+following the description given in its first argument (which must be a string).
+The format string follows the same rules as the <code>printf</code> family of
+standard C&nbsp;functions.
+The only differences are that the options/modifiers
+<code>*</code>, <code>l</code>, <code>L</code>, <code>n</code>, <code>p</code>,
+and <code>h</code> are not supported
+and that there is an extra option, <code>q</code>.
+The <code>q</code> option formats a string in a form suitable to be safely read
+back by the Lua interpreter:
+the string is written between double quotes,
+and all double quotes, newlines, embedded zeros,
+and backslashes in the string
+are correctly escaped when written.
+For instance, the call
+
+<pre>
+     string.format('%q', 'a string with "quotes" and \n new line')
+</pre><p>
+will produce the string:
+
+<pre>
+     "a string with \"quotes\" and \
+      new line"
+</pre>
+
+<p>
+The options <code>c</code>, <code>d</code>, <code>E</code>, <code>e</code>, <code>f</code>,
+<code>g</code>, <code>G</code>, <code>i</code>, <code>o</code>, <code>u</code>, <code>X</code>, and <code>x</code> all
+expect a number as argument,
+whereas <code>q</code> and <code>s</code> expect a string.
+
+
+<p>
+This function does not accept string values
+containing embedded zeros,
+except as arguments to the <code>q</code> option.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-string.gmatch"><code>string.gmatch (s, pattern)</code></a></h3>
+Returns an iterator function that,
+each time it is called,
+returns the next captures from <code>pattern</code> over string <code>s</code>.
+If <code>pattern</code> specifies no captures,
+then the whole match is produced in each call.
+
+
+<p>
+As an example, the following loop
+
+<pre>
+     s = "hello world from Lua"
+     for w in string.gmatch(s, "%a+") do
+       print(w)
+     end
+</pre><p>
+will iterate over all the words from string <code>s</code>,
+printing one per line.
+The next example collects all pairs <code>key=value</code> from the
+given string into a table:
+
+<pre>
+     t = {}
+     s = "from=world, to=Lua"
+     for k, v in string.gmatch(s, "(%w+)=(%w+)") do
+       t[k] = v
+     end
+</pre>
+
+<p>
+For this function, a '<code>^</code>' at the start of a pattern does not
+work as an anchor, as this would prevent the iteration.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-string.gsub"><code>string.gsub (s, pattern, repl [, n])</code></a></h3>
+Returns a copy of <code>s</code>
+in which all (or the first <code>n</code>, if given)
+occurrences of the <code>pattern</code> have been
+replaced by a replacement string specified by <code>repl</code>,
+which may be a string, a table, or a function.
+<code>gsub</code> also returns, as its second value,
+the total number of matches that occurred.
+
+
+<p>
+If <code>repl</code> is a string, then its value is used for replacement.
+The character&nbsp;<code>%</code> works as an escape character:
+any sequence in <code>repl</code> of the form <code>%<em>n</em></code>,
+with <em>n</em> between 1 and 9,
+stands for the value of the <em>n</em>-th captured substring (see below).
+The sequence <code>%0</code> stands for the whole match.
+The sequence <code>%%</code> stands for a single&nbsp;<code>%</code>.
+
+
+<p>
+If <code>repl</code> is a table, then the table is queried for every match,
+using the first capture as the key;
+if the pattern specifies no captures,
+then the whole match is used as the key.
+
+
+<p>
+If <code>repl</code> is a function, then this function is called every time a
+match occurs, with all captured substrings passed as arguments,
+in order;
+if the pattern specifies no captures,
+then the whole match is passed as a sole argument.

+If it finds one, then <code>match</code> returns
+the captures from the pattern;
+otherwise it returns <b>nil</b>.
+If <code>pattern</code> specifies no captures,

+<h3>5.4.1 - <a name="5.4.1">Patterns</a></h3>
+
+
+<h4>Character Class:</h4><p>
+A <em>character class</em> is used to represent a set of characters.
+The following combinations are allowed in describing a character class:
+
+<ul>
+
+<li><b><em>x</em>:</b>
+(where <em>x</em> is not one of the <em>magic characters</em>
+<code>^$()%.[]*+-?</code>)
+represents the character <em>x</em> itself.
+</li>
+
+<li><b><code>.</code>:</b> (a dot) represents all characters.</li>
+
+<li><b><code>%a</code>:</b> represents all letters.</li>
+
+<li><b><code>%c</code>:</b> represents all control characters.</li>
+
+<li><b><code>%d</code>:</b> represents all digits.</li>
+
+<li><b><code>%l</code>:</b> represents all lowercase letters.</li>
+
+<li><b><code>%p</code>:</b> represents all punctuation characters.</li>
+
+<li><b><code>%s</code>:</b> represents all space characters.</li>
+
+<li><b><code>%u</code>:</b> represents all uppercase letters.</li>
+
+<li><b><code>%w</code>:</b> represents all alphanumeric characters.</li>
+
+<li><b><code>%x</code>:</b> represents all hexadecimal digits.</li>
+
+<li><b><code>%z</code>:</b> represents the character with representation 0.</li>
+
+<li><b><code>%<em>x</em></code>:</b> (where <em>x</em> is any non-alphanumeric character)
+represents the character <em>x</em>.
+This is the standard way to escape the magic characters.
+Any punctuation character (even the non magic)
+can be preceded by a '<code>%</code>'
+when used to represent itself in a pattern.
+</li>
+
+<li><b><code>[<em>set</em>]</code>:</b>
+represents the class which is the union of all
+characters in <em>set</em>.
+A range of characters may be specified by
+separating the end characters of the range with a '<code>-</code>'.
+All classes <code>%</code><em>x</em> described above may also be used as
+components in <em>set</em>.
+All other characters in <em>set</em> represent themselves.
+For example, <code>[%w_]</code> (or <code>[_%w]</code>)
+represents all alphanumeric characters plus the underscore,
+<code>[0-7]</code> represents the octal digits,
+and <code>[0-7%l%-]</code> represents the octal digits plus
+the lowercase letters plus the '<code>-</code>' character.
+
+
+<p>
+The interaction between ranges and classes is not defined.
+Therefore, patterns like <code>[%a-z]</code> or <code>[a-%%]</code>
+have no meaning.
+</li>
+
+<li><b><code>[^<em>set</em>]</code>:</b>
+represents the complement of <em>set</em>,
+where <em>set</em> is interpreted as above.
+</li>
+
+</ul><p>
+For all classes represented by single letters (<code>%a</code>, <code>%c</code>, etc.),
+the corresponding uppercase letter represents the complement of the class.
+For instance, <code>%S</code> represents all non-space characters.
+
+
+<p>
+The definitions of letter, space, and other character groups
+depend on the current locale.
+In particular, the class <code>[a-z]</code> may not be equivalent to <code>%l</code>.
+
+
+
+
+
+<h4>Pattern Item:</h4><p>
+A <em>pattern item</em> may be
+
+<ul>
+
+<li>
+a single character class,
+which matches any single character in the class;
+</li>
+
+<li>
+a single character class followed by '<code>*</code>',
+which matches 0 or more repetitions of characters in the class.
+These repetition items will always match the longest possible sequence;
+</li>
+
+<li>
+a single character class followed by '<code>+</code>',
+which matches 1 or more repetitions of characters in the class.
+These repetition items will always match the longest possible sequence;
+</li>
+
+<li>
+a single character class followed by '<code>-</code>',
+which also matches 0 or more repetitions of characters in the class.
+Unlike '<code>*</code>',
+these repetition items will always match the <em>shortest</em> possible sequence;
+</li>
+
+<li>
+a single character class followed by '<code>?</code>',
+which matches 0 or 1 occurrence of a character in the class;
+</li>
+
+<li>
+<code>%<em>n</em></code>, for <em>n</em> between 1 and 9;
+such item matches a substring equal to the <em>n</em>-th captured string
+(see below);
+</li>
+
+<li>
+<code>%b<em>xy</em></code>, where <em>x</em> and <em>y</em> are two distinct characters;
+such item matches strings that start with&nbsp;<em>x</em>, end with&nbsp;<em>y</em>,
+and where the <em>x</em> and <em>y</em> are <em>balanced</em>.
+This means that, if one reads the string from left to right,
+counting <em>+1</em> for an <em>x</em> and <em>-1</em> for a <em>y</em>,
+the ending <em>y</em> is the first <em>y</em> where the count reaches 0.
+For instance, the item <code>%b()</code> matches expressions with
+balanced parentheses.
+</li>
+
+</ul>
+
+
+
+
+<h4>Pattern:</h4><p>
+A <em>pattern</em> is a sequence of pattern items.
+A '<code>^</code>' at the beginning of a pattern anchors the match at the
+beginning of the subject string.
+A '<code>$</code>' at the end of a pattern anchors the match at the
+end of the subject string.
+At other positions,
+'<code>^</code>' and '<code>$</code>' have no special meaning and represent themselves.
+
+
+
+
+
+<h4>Captures:</h4><p>
+A pattern may contain sub-patterns enclosed in parentheses;
+they describe <em>captures</em>.
+When a match succeeds, the substrings of the subject string
+that match captures are stored (<em>captured</em>) for future use.
+Captures are numbered according to their left parentheses.
+For instance, in the pattern <code>"(a*(.)%w(%s*))"</code>,
+the part of the string matching <code>"a*(.)%w(%s*)"</code> is
+stored as the first capture (and therefore has number&nbsp;1);
+the character matching "<code>.</code>" is captured with number&nbsp;2,
+and the part matching "<code>%s*</code>" has number&nbsp;3.
+
+
+<p>
+As a special case, the empty capture <code>()</code> captures
+the current string position (a number).
+For instance, if we apply the pattern <code>"()aa()"</code> on the
+string <code>"flaaap"</code>, there will be two captures: 3&nbsp;and&nbsp;5.
+
+
+<p>
+A pattern cannot contain embedded zeros.  Use <code>%z</code> instead.

+<h2>5.5 - <a name="5.5">Table Manipulation</a></h2><p>
+This library provides generic functions for table manipulation.
+It provides all its functions inside the table <a name="pdf-table"><code>table</code></a>.
+
+
+<p>
+Most functions in the table library assume that the table
+represents an array or a list.
+For these functions, when we talk about the "length" of a table
+we mean the result of the length operator.
+
+
+<p>
+<hr><h3><a name="pdf-table.concat"><code>table.concat (table [, sep [, i [, j]]])</code></a></h3>
+Given an array where all elements are strings or numbers,
+returns <code>table[i]..sep..table[i+1] &middot;&middot;&middot; sep..table[j]</code>.
+The default value for <code>sep</code> is the empty string,
+the default for <code>i</code> is 1,
+and the default for <code>j</code> is the length of the table.
+If <code>i</code> is greater than <code>j</code>, returns the empty string.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-table.insert"><code>table.insert (table, [pos,] value)</code></a></h3>
+
+
+<p>
+Inserts element <code>value</code> at position <code>pos</code> in <code>table</code>,
+shifting up other elements to open space, if necessary.
+The default value for <code>pos</code> is <code>n+1</code>,
+where <code>n</code> is the length of the table (see <a href="#2.5.5">&sect;2.5.5</a>),
+so that a call <code>table.insert(t,x)</code> inserts <code>x</code> at the end
+of table <code>t</code>.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-table.maxn"><code>table.maxn (table)</code></a></h3>
+
+
+<p>
+Returns the largest positive numerical index of the given table,
+or zero if the table has no positive numerical indices.
+(To do its job this function does a linear traversal of
+the whole table.) 
+
+
+
+
+<p>
+<hr><h3><a name="pdf-table.remove"><code>table.remove (table [, pos])</code></a></h3>
+
+
+<p>
+Removes from <code>table</code> the element at position <code>pos</code>,
+shifting down other elements to close the space, if necessary.
+Returns the value of the removed element.
+The default value for <code>pos</code> is <code>n</code>,
+where <code>n</code> is the length of the table,
+so that a call <code>table.remove(t)</code> removes the last element
+of table <code>t</code>.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-table.sort"><code>table.sort (table [, comp])</code></a></h3>
+Sorts table elements in a given order, <em>in-place</em>,
+from <code>table[1]</code> to <code>table[n]</code>,
+where <code>n</code> is the length of the table.
+If <code>comp</code> is given,
+then it must be a function that receives two table elements,
+and returns true
+when the first is less than the second
+(so that <code>not comp(a[i+1],a[i])</code> will be true after the sort).
+If <code>comp</code> is not given,
+then the standard Lua operator <code>&lt;</code> is used instead.
+
+
+<p>
+The sort algorithm is not stable;
+that is, elements considered equal by the given order
+may have their relative positions changed by the sort.

+<h2>5.7 - <a name="5.7">Input and Output Facilities</a></h2>
+
+<p>
+The I/O library provides two different styles for file manipulation.
+The first one uses implicit file descriptors;
+that is, there are operations to set a default input file and a
+default output file,
+and all input/output operations are over these default files.
+The second style uses explicit file descriptors.
+
+
+<p>
+When using implicit file descriptors,
+all operations are supplied by table <a name="pdf-io"><code>io</code></a>.
+When using explicit file descriptors,
+the operation <a href="#pdf-io.open"><code>io.open</code></a> returns a file descriptor
+and then all operations are supplied as methods of the file descriptor.
+
+
+<p>
+The table <code>io</code> also provides
+three predefined file descriptors with their usual meanings from C:
+<a name="pdf-io.stdin"><code>io.stdin</code></a>, <a name="pdf-io.stdout"><code>io.stdout</code></a>, and <a name="pdf-io.stderr"><code>io.stderr</code></a>.
+The I/O library never closes these files.
+
+
+<p>
+Unless otherwise stated,
+all I/O functions return <b>nil</b> on failure
+(plus an error message as a second result and
+a system-dependent error code as a third result)
+and some value different from <b>nil</b> on success.
+
+
+<p>
+<hr><h3><a name="pdf-io.close"><code>io.close ([file])</code></a></h3>
+
+
+<p>
+Equivalent to <code>file:close()</code>.
+Without a <code>file</code>, closes the default output file.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-io.flush"><code>io.flush ()</code></a></h3>
+
+
+<p>
+Equivalent to <code>file:flush</code> over the default output file.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-io.input"><code>io.input ([file])</code></a></h3>
+
+
+<p>
+When called with a file name, it opens the named file (in text mode),
+and sets its handle as the default input file.
+When called with a file handle,
+it simply sets this file handle as the default input file.
+When called without parameters,
+it returns the current default input file.
+
+
+<p>
+In case of errors this function raises the error,
+instead of returning an error code.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-io.lines"><code>io.lines ([filename])</code></a></h3>
+
+
+<p>
+Opens the given file name in read mode
+and returns an iterator function that,
+each time it is called,
+returns a new line from the file.
+Therefore, the construction
+
+<pre>
+     for line in io.lines(filename) do <em>body</em> end
+</pre><p>
+will iterate over all lines of the file.
+When the iterator function detects the end of file,
+it returns <b>nil</b> (to finish the loop) and automatically closes the file.
+
+
+<p>
+The call <code>io.lines()</code> (with no file name) is equivalent
+to <code>io.input():lines()</code>;
+that is, it iterates over the lines of the default input file.
+In this case it does not close the file when the loop ends.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-io.open"><code>io.open (filename [, mode])</code></a></h3>
+
+
+<p>
+This function opens a file,
+in the mode specified in the string <code>mode</code>.
+It returns a new file handle,

+The <code>mode</code> string can be any of the following:
+
+<ul>
+<li><b>"r":</b> read mode (the default);</li>
+<li><b>"w":</b> write mode;</li>
+<li><b>"a":</b> append mode;</li>
+<li><b>"r+":</b> update mode, all previous data is preserved;</li>
+<li><b>"w+":</b> update mode, all previous data is erased;</li>
+<li><b>"a+":</b> append update mode, previous data is preserved,
+  writing is only allowed at the end of file.</li>
+</ul><p>
+The <code>mode</code> string may also have a '<code>b</code>' at the end,
+which is needed in some systems to open the file in binary mode.
+This string is exactly what is used in the
+standard&nbsp;C function <code>fopen</code>.

+
+
+
+
+<p>
+<hr><h3><a name="pdf-io.popen"><code>io.popen (prog [, mode])</code></a></h3>
+
+
+<p>
+Starts program <code>prog</code> in a separated process and returns
+a file handle that you can use to read data from this program
+(if <code>mode</code> is <code>"r"</code>, the default)
+or to write data to this program
+(if <code>mode</code> is <code>"w"</code>).
+

+
+
+<p>
+<hr><h3><a name="pdf-io.tmpfile"><code>io.tmpfile ()</code></a></h3>
+
+
+<p>
+Returns a handle for a temporary file.
+This file is opened in update mode
+and it is automatically removed when the program ends.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-io.type"><code>io.type (obj)</code></a></h3>
+
+
+<p>
+Checks whether <code>obj</code> is a valid file handle.
+Returns the string <code>"file"</code> if <code>obj</code> is an open file handle,
+<code>"closed file"</code> if <code>obj</code> is a closed file handle,
+or <b>nil</b> if <code>obj</code> is not a file handle.
+

+
+
+
+
+<p>
+<hr><h3><a name="pdf-file:close"><code>file:close ()</code></a></h3>
+
+
+<p>
+Closes <code>file</code>.
+Note that files are automatically closed when
+their handles are garbage collected,
+but that takes an unpredictable amount of time to happen.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-file:flush"><code>file:flush ()</code></a></h3>
+
+
+<p>
+Saves any written data to <code>file</code>.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-file:lines"><code>file:lines ()</code></a></h3>
+
+
+<p>
+Returns an iterator function that,
+each time it is called,
+returns a new line from the file.
+Therefore, the construction
+
+<pre>
+     for line in file:lines() do <em>body</em> end
+</pre><p>
+will iterate over all lines of the file.
+(Unlike <a href="#pdf-io.lines"><code>io.lines</code></a>, this function does not close the file
+when the loop ends.)
+
+
+
+
+<p>
+<hr><h3><a name="pdf-file:read"><code>file:read (&middot;&middot;&middot;)</code></a></h3>
+
+
+<p>
+Reads the file <code>file</code>,
+according to the given formats, which specify what to read.
+For each format,
+the function returns a string (or a number) with the characters read,
+or <b>nil</b> if it cannot read data with the specified format.
+When called without formats,
+it uses a default format that reads the entire next line
+(see below).
+
+
+<p>
+The available formats are
+
+<ul>
+
+<li><b>"*n":</b>
+reads a number;
+this is the only format that returns a number instead of a string.
+</li>
+
+<li><b>"*a":</b>
+reads the whole file, starting at the current position.
+On end of file, it returns the empty string.
+</li>
+
+<li><b>"*l":</b>
+reads the next line (skipping the end of line),
+returning <b>nil</b> on end of file.
+This is the default format.
+</li>
+
+<li><b><em>number</em>:</b>
+reads a string with up to this number of characters,
+returning <b>nil</b> on end of file.
+If number is zero,
+it reads nothing and returns an empty string,
+or <b>nil</b> on end of file.
+</li>
+
+</ul>
+
+
+
+<p>
+<hr><h3><a name="pdf-file:seek"><code>file:seek ([whence] [, offset])</code></a></h3>
+
+
+<p>
+Sets and gets the file position,
+measured from the beginning of the file,
+to the position given by <code>offset</code> plus a base
+specified by the string <code>whence</code>, as follows:
+
+<ul>
+<li><b>"set":</b> base is position 0 (beginning of the file);</li>
+<li><b>"cur":</b> base is current position;</li>
+<li><b>"end":</b> base is end of file;</li>
+</ul><p>
+In case of success, function <code>seek</code> returns the final file position,
+measured in bytes from the beginning of the file.
+If this function fails, it returns <b>nil</b>,
+plus a string describing the error.
+
+
+<p>
+The default value for <code>whence</code> is <code>"cur"</code>,
+and for <code>offset</code> is 0.
+Therefore, the call <code>file:seek()</code> returns the current
+file position, without changing it;
+the call <code>file:seek("set")</code> sets the position to the
+beginning of the file (and returns 0);
+and the call <code>file:seek("end")</code> sets the position to the
+end of the file, and returns its size.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-file:setvbuf"><code>file:setvbuf (mode [, size])</code></a></h3>
+
+
+<p>
+Sets the buffering mode for an output file.
+There are three available modes:
+
+<ul>
+
+<li><b>"no":</b>
+no buffering; the result of any output operation appears immediately.
+</li>
+
+<li><b>"full":</b>
+full buffering; output operation is performed only
+when the buffer is full (or when you explicitly <code>flush</code> the file
+(see <a href="#pdf-io.flush"><code>io.flush</code></a>)).
+</li>
+
+<li><b>"line":</b>
+line buffering; output is buffered until a newline is output
+or there is any input from some special files
+(such as a terminal device).
+</li>
+
+</ul><p>
+For the last two cases, <code>size</code>
+specifies the size of the buffer, in bytes.
+The default is an appropriate size.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-file:write"><code>file:write (&middot;&middot;&middot;)</code></a></h3>

+
+
+<p>
+<hr><h3><a name="pdf-os.clock"><code>os.clock ()</code></a></h3>
+
+
+<p>

+used by the program.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-os.date"><code>os.date ([format [, time]])</code></a></h3>
+
+
+<p>
+Returns a string or a table containing date and time,
+formatted according to the given string <code>format</code>.
+
+
+<p>
+If the <code>time</code> argument is present,
+this is the time to be formatted
+(see the <a href="#pdf-os.time"><code>os.time</code></a> function for a description of this value).
+Otherwise, <code>date</code> formats the current time.
+
+
+<p>
+If <code>format</code> starts with '<code>!</code>',
+then the date is formatted in Coordinated Universal Time.
+After this optional character,
+if <code>format</code> is the string "<code>*t</code>",
+then <code>date</code> returns a table with the following fields:
+<code>year</code> (four digits), <code>month</code> (1--12), <code>day</code> (1--31),
+<code>hour</code> (0--23), <code>min</code> (0--59), <code>sec</code> (0--61),
+<code>wday</code> (weekday, Sunday is&nbsp;1),
+<code>yday</code> (day of the year),
+and <code>isdst</code> (daylight saving flag, a boolean).
+
+
+<p>
+If <code>format</code> is not "<code>*t</code>",
+then <code>date</code> returns the date as a string,
+formatted according to the same rules as the C&nbsp;function <code>strftime</code>.
+
+
+<p>
+When called without arguments,
+<code>date</code> returns a reasonable date and time representation that depends on
+the host system and on the current locale
+(that is, <code>os.date()</code> is equivalent to <code>os.date("%c")</code>).

+
+
+
+<p>
+<hr><h3><a name="pdf-os.difftime"><code>os.difftime (t2, t1)</code></a></h3>

+
+
+
+
+<p>
+<hr><h3><a name="pdf-os.execute"><code>os.execute ([command])</code></a></h3>
+
+
+<p>
+This function is equivalent to the C&nbsp;function <code>system</code>.
+It passes <code>command</code> to be executed by an operating system shell.
+It returns a status code, which is system-dependent.
+If <code>command</code> is absent, then it returns nonzero if a shell is available
+and zero otherwise.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-os.exit"><code>os.exit ([code])</code></a></h3>
+
+
+<p>
+Calls the C&nbsp;function <code>exit</code>,
+with an optional <code>code</code>,

+The default value for <code>code</code> is the success code.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-os.getenv"><code>os.getenv (varname)</code></a></h3>
+
+
+<p>
+Returns the value of the process environment variable <code>varname</code>,

+
+
+
+
+<p>
+<hr><h3><a name="pdf-os.remove"><code>os.remove (filename)</code></a></h3>
+
+
+<p>
+Deletes the file or directory with the given name.
+Directories must be empty to be removed.

+plus a string describing the error.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-os.rename"><code>os.rename (oldname, newname)</code></a></h3>

+
+
+
+<p>
+<hr><h3><a name="pdf-os.setlocale"><code>os.setlocale (locale [, category])</code></a></h3>
+
+
+<p>
+Sets the current locale of the program.
+<code>locale</code> is a string specifying a locale;
+<code>category</code> is an optional string describing which category to change:
+<code>"all"</code>, <code>"collate"</code>, <code>"ctype"</code>,
+<code>"monetary"</code>, <code>"numeric"</code>, or <code>"time"</code>;
+the default category is <code>"all"</code>.
+The function returns the name of the new locale,
+or <b>nil</b> if the request cannot be honored.
+
+
+<p>
+If <code>locale</code> is the empty string,
+the current locale is set to an implementation-defined native locale.
+If <code>locale</code> is the string "<code>C</code>",
+the current locale is set to the standard C locale.
+
+
+<p>
+When called with <b>nil</b> as the first argument,

+This table must have fields <code>year</code>, <code>month</code>, and <code>day</code>,
+and may have fields <code>hour</code>, <code>min</code>, <code>sec</code>, and <code>isdst</code>
+(for a description of these fields, see the <a href="#pdf-os.date"><code>os.date</code></a> function).
+
+
+<p>
+The returned value is a number, whose meaning depends on your system.
+In POSIX, Windows, and some other systems, this number counts the number
+of seconds since some given start time (the "epoch").
+In other systems, the meaning is not specified,
+and the number returned by <code>time</code> can be used only as an argument to

+<h2>5.9 - <a name="5.9">The Debug Library</a></h2>
+
+<p>
+This library provides
+the functionality of the debug interface to Lua programs.
+You should exert care when using this library.
+The functions provided here should be used exclusively for debugging
+and similar tasks, such as profiling.
+Please resist the temptation to use them as a
+usual programming tool:
+they can be very slow.
+Moreover, several of these functions
+violate some assumptions about Lua code
+(e.g., that variables local to a function
+cannot be accessed from outside or
+that userdata metatables cannot be changed by Lua code)
+and therefore can compromise otherwise secure code.
+
+
+<p>
+All functions in this library are provided
+inside the <a name="pdf-debug"><code>debug</code></a> table.
+All functions that operate over a thread
+have an optional first argument which is the
+thread to operate over.
+The default is always the current thread.
+
+
+<p>
+<hr><h3><a name="pdf-debug.debug"><code>debug.debug ()</code></a></h3>
+
+
+<p>
+Enters an interactive mode with the user,
+running each string that the user enters.
+Using simple commands and other debug facilities,
+the user can inspect global and local variables,
+change their values, evaluate expressions, and so on.
+A line containing only the word <code>cont</code> finishes this function,
+so that the caller continues its execution.
+
+
+<p>
+Note that commands for <code>debug.debug</code> are not lexically nested
+within any function, and so have no direct access to local variables.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-debug.getfenv"><code>debug.getfenv (o)</code></a></h3>
+Returns the environment of object <code>o</code>.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-debug.gethook"><code>debug.gethook ([thread])</code></a></h3>
+
+
+<p>
+Returns the current hook settings of the thread, as three values:
+the current hook function, the current hook mask,
+and the current hook count
+(as set by the <a href="#pdf-debug.sethook"><code>debug.sethook</code></a> function).
+
+
+
+
+<p>
+<hr><h3><a name="pdf-debug.getinfo"><code>debug.getinfo ([thread,] function [, what])</code></a></h3>
+
+
+<p>
+Returns a table with information about a function.
+You can give the function directly,
+or you can give a number as the value of <code>function</code>,
+which means the function running at level <code>function</code> of the call stack
+of the given thread:
+level&nbsp;0 is the current function (<code>getinfo</code> itself);
+level&nbsp;1 is the function that called <code>getinfo</code>;
+and so on.
+If <code>function</code> is a number larger than the number of active functions,
+then <code>getinfo</code> returns <b>nil</b>.
+
+
+<p>
+The returned table may contain all the fields returned by <a href="#lua_getinfo"><code>lua_getinfo</code></a>,
+with the string <code>what</code> describing which fields to fill in.
+The default for <code>what</code> is to get all information available,
+except the table of valid lines.
+If present,
+the option '<code>f</code>'
+adds a field named <code>func</code> with the function itself.
+If present,
+the option '<code>L</code>'
+adds a field named <code>activelines</code> with the table of
+valid lines.
+
+
+<p>
+For instance, the expression <code>debug.getinfo(1,"n").name</code> returns
+a table with a name for the current function,
+if a reasonable name can be found,
+and the expression <code>debug.getinfo(print)</code>
+returns a table with all available information
+about the <a href="#pdf-print"><code>print</code></a> function.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-debug.getlocal"><code>debug.getlocal ([thread,] level, local)</code></a></h3>
+
+
+<p>
+This function returns the name and the value of the local variable
+with index <code>local</code> of the function at level <code>level</code> of the stack.
+(The first parameter or local variable has index&nbsp;1, and so on,
+until the last active local variable.)
+The function returns <b>nil</b> if there is no local
+variable with the given index,
+and raises an error when called with a <code>level</code> out of range.
+(You can call <a href="#pdf-debug.getinfo"><code>debug.getinfo</code></a> to check whether the level is valid.)
+
+
+<p>
+Variable names starting with '<code>(</code>' (open parentheses)
+represent internal variables
+(loop control variables, temporaries, and C&nbsp;function locals).
+
+
+
+
+<p>
+<hr><h3><a name="pdf-debug.getmetatable"><code>debug.getmetatable (object)</code></a></h3>
+

+
+
+
+
+<p>
+<hr><h3><a name="pdf-debug.getregistry"><code>debug.getregistry ()</code></a></h3>

+
+
+
+
+<p>
+<hr><h3><a name="pdf-debug.getupvalue"><code>debug.getupvalue (func, up)</code></a></h3>
+
+
+<p>
+This function returns the name and the value of the upvalue
+with index <code>up</code> of the function <code>func</code>.
+The function returns <b>nil</b> if there is no upvalue with the given index.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-debug.setfenv"><code>debug.setfenv (object, table)</code></a></h3>
+
+
+<p>
+Sets the environment of the given <code>object</code> to the given <code>table</code>.
+Returns <code>object</code>.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-debug.sethook"><code>debug.sethook ([thread,] hook, mask [, count])</code></a></h3>
+
+
+<p>
+Sets the given function as a hook.
+The string <code>mask</code> and the number <code>count</code> describe
+when the hook will be called.
+The string mask may have the following characters,
+with the given meaning:
+
+<ul>
+<li><b><code>"c"</code>:</b> the hook is called every time Lua calls a function;</li>
+<li><b><code>"r"</code>:</b> the hook is called every time Lua returns from a function;</li>
+<li><b><code>"l"</code>:</b> the hook is called every time Lua enters a new line of code.</li>
+</ul><p>
+With a <code>count</code> different from zero,
+the hook is called after every <code>count</code> instructions.
+
+
+<p>
+When called without arguments,
+<a href="#pdf-debug.sethook"><code>debug.sethook</code></a> turns off the hook.
+
+
+<p>
+When the hook is called, its first parameter is a string
+describing the event that has triggered its call:
+<code>"call"</code>, <code>"return"</code> (or <code>"tail return"</code>),
+<code>"line"</code>, and <code>"count"</code>.
+For line events,
+the hook also gets the new line number as its second parameter.
+Inside a hook,
+you can call <code>getinfo</code> with level&nbsp;2 to get more information about
+the running function
+(level&nbsp;0 is the <code>getinfo</code> function,
+and level&nbsp;1 is the hook function),
+unless the event is <code>"tail return"</code>.
+In this case, Lua is only simulating the return,
+and a call to <code>getinfo</code> will return invalid data.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-debug.setlocal"><code>debug.setlocal ([thread,] level, local, value)</code></a></h3>
+
+
+<p>
+This function assigns the value <code>value</code> to the local variable
+with index <code>local</code> of the function at level <code>level</code> of the stack.
+The function returns <b>nil</b> if there is no local
+variable with the given index,
+and raises an error when called with a <code>level</code> out of range.
+(You can call <code>getinfo</code> to check whether the level is valid.)
+Otherwise, it returns the name of the local variable.

+
+
+
+
+<p>
+<hr><h3><a name="pdf-debug.setupvalue"><code>debug.setupvalue (func, up, value)</code></a></h3>
+
+
+<p>
+This function assigns the value <code>value</code> to the upvalue
+with index <code>up</code> of the function <code>func</code>.
+The function returns <b>nil</b> if there is no upvalue
+with the given index.
+Otherwise, it returns the name of the upvalue.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-debug.traceback"><code>debug.traceback ([thread,] [message] [, level])</code></a></h3>
+
+
+<p>
+Returns a string with a traceback of the call stack.
+An optional <code>message</code> string is appended
+at the beginning of the traceback.
+An optional <code>level</code> number tells at which level
+to start the traceback
+(default is 1, the function calling <code>traceback</code>).
+
+
+
+

+
+<h1>6 - <a name="6">Lua Stand-alone</a></h1>
+
+<p>
+Although Lua has been designed as an extension language,
+to be embedded in a host C&nbsp;program,
+it is also frequently used as a stand-alone language.
+An interpreter for Lua as a stand-alone language,
+called simply <code>lua</code>,
+is provided with the standard distribution.
+The stand-alone interpreter includes
+all standard libraries, including the debug library.
+Its usage is:
+
+<pre>
+     lua [options] [script [args]]
+</pre><p>
+The options are:
+
+<ul>
+<li><b><code>-e <em>stat</em></code>:</b> executes string <em>stat</em>;</li>
+<li><b><code>-l <em>mod</em></code>:</b> "requires" <em>mod</em>;</li>
+<li><b><code>-i</code>:</b> enters interactive mode after running <em>script</em>;</li>
+<li><b><code>-v</code>:</b> prints version information;</li>
+<li><b><code>--</code>:</b> stops handling options;</li>
+<li><b><code>-</code>:</b> executes <code>stdin</code> as a file and stops handling options.</li>
+</ul><p>
+After handling its options, <code>lua</code> runs the given <em>script</em>,
+passing to it the given <em>args</em> as string arguments.
+When called without arguments,
+<code>lua</code> behaves as <code>lua -v -i</code>
+when the standard input (<code>stdin</code>) is a terminal,
+and as <code>lua -</code> otherwise.
+
+
+<p>
+Before running any argument,
+the interpreter checks for an environment variable <a name="pdf-LUA_INIT"><code>LUA_INIT</code></a>.
+If its format is <code>@<em>filename</em></code>,
+then <code>lua</code> executes the file.
+Otherwise, <code>lua</code> executes the string itself.
+
+
+<p>
+All options are handled in order, except <code>-i</code>.
+For instance, an invocation like
+
+<pre>
+     $ lua -e'a=1' -e 'print(a)' script.lua
+</pre><p>
+will first set <code>a</code> to 1, then print the value of <code>a</code> (which is '<code>1</code>'),
+and finally run the file <code>script.lua</code> with no arguments.
+(Here <code>$</code> is the shell prompt. Your prompt may be different.)
+
+
+<p>
+Before starting to run the script,
+<code>lua</code> collects all arguments in the command line
+in a global table called <code>arg</code>.
+The script name is stored at index 0,
+the first argument after the script name goes to index 1,
+and so on.
+Any arguments before the script name
+(that is, the interpreter name plus the options)
+go to negative indices.
+For instance, in the call
+
+<pre>
+     $ lua -la b.lua t1 t2
+</pre><p>
+the interpreter first runs the file <code>a.lua</code>,
+then creates a table
+
+<pre>
+     arg = { [-2] = "lua", [-1] = "-la",
+             [0] = "b.lua",
+             [1] = "t1", [2] = "t2" }
+</pre><p>
+and finally runs the file <code>b.lua</code>.
+The script is called with <code>arg[1]</code>, <code>arg[2]</code>, &middot;&middot;&middot;
+as arguments;
+it can also access these arguments with the vararg expression '<code>...</code>'.
+
+
+<p>
+In interactive mode,
+if you write an incomplete statement,
+the interpreter waits for its completion
+by issuing a different prompt.
+
+
+<p>
+If the global variable <a name="pdf-_PROMPT"><code>_PROMPT</code></a> contains a string,
+then its value is used as the prompt.
+Similarly, if the global variable <a name="pdf-_PROMPT2"><code>_PROMPT2</code></a> contains a string,
+its value is used as the secondary prompt
+(issued during incomplete statements).
+Therefore, both prompts can be changed directly on the command line
+or in any Lua programs by assigning to <code>_PROMPT</code>.
+See the next example:
+
+<pre>
+     $ lua -e"_PROMPT='myprompt&gt; '" -i
+</pre><p>
+(The outer pair of quotes is for the shell,
+the inner pair is for Lua.)
+Note the use of <code>-i</code> to enter interactive mode;
+otherwise,
+the program would just end silently
+right after the assignment to <code>_PROMPT</code>.
+
+
+<p>
+To allow the use of Lua as a
+script interpreter in Unix systems,
+the stand-alone interpreter skips
+the first line of a chunk if it starts with <code>#</code>.
+Therefore, Lua scripts can be made into executable programs
+by using <code>chmod +x</code> and the&nbsp;<code>#!</code> form,
+as in
+
+<pre>
+     #!/usr/local/bin/lua
+</pre><p>
+(Of course,
+the location of the Lua interpreter may be different in your machine.
+If <code>lua</code> is in your <code>PATH</code>,
+then 
+
+<pre>
+     #!/usr/bin/env lua
+</pre><p>
+is a more portable solution.) 
+
+
+
+<h1>7 - <a name="7">Incompatibilities with the Previous Version</a></h1>
+
+<p>
+Here we list the incompatibilities that you may find when moving a program
+from Lua&nbsp;5.0 to Lua&nbsp;5.1.
+You can avoid most of the incompatibilities compiling Lua with
+appropriate options (see file <code>luaconf.h</code>).
+However,
+all these compatibility options will be removed in the next version of Lua.
+
+
+
+<h2>7.1 - <a name="7.1">Changes in the Language</a></h2>
+<ul>
+
+<li>
+The vararg system changed from the pseudo-argument <code>arg</code> with a
+table with the extra arguments to the vararg expression.
+(See compile-time option <code>LUA_COMPAT_VARARG</code> in <code>luaconf.h</code>.)
+</li>
+
+<li>
+There was a subtle change in the scope of the implicit
+variables of the <b>for</b> statement and for the <b>repeat</b> statement.
+</li>
+
+<li>
+The long string/long comment syntax (<code>[[<em>string</em>]]</code>)
+does not allow nesting.
+You can use the new syntax (<code>[=[<em>string</em>]=]</code>) in these cases.
+(See compile-time option <code>LUA_COMPAT_LSTR</code> in <code>luaconf.h</code>.)
+</li>
+
+</ul>
+
+
+
+
+<h2>7.2 - <a name="7.2">Changes in the Libraries</a></h2>
+<ul>
+
+<li>
+Function <code>string.gfind</code> was renamed <a href="#pdf-string.gmatch"><code>string.gmatch</code></a>.
+(See compile-time option <code>LUA_COMPAT_GFIND</code> in <code>luaconf.h</code>.)
+</li>
+
+<li>
+When <a href="#pdf-string.gsub"><code>string.gsub</code></a> is called with a function as its
+third argument,
+whenever this function returns <b>nil</b> or <b>false</b> the
+replacement string is the whole match,
+instead of the empty string.
+</li>
+
+<li>
+Function <code>table.setn</code> was deprecated.
+Function <code>table.getn</code> corresponds
+to the new length operator (<code>#</code>);
+use the operator instead of the function.
+(See compile-time option <code>LUA_COMPAT_GETN</code> in <code>luaconf.h</code>.)
+</li>
+
+<li>
+Function <code>loadlib</code> was renamed <a href="#pdf-package.loadlib"><code>package.loadlib</code></a>.
+(See compile-time option <code>LUA_COMPAT_LOADLIB</code> in <code>luaconf.h</code>.)
+</li>
+
+<li>
+Function <code>math.mod</code> was renamed <a href="#pdf-math.fmod"><code>math.fmod</code></a>.
+(See compile-time option <code>LUA_COMPAT_MOD</code> in <code>luaconf.h</code>.)
+</li>
+
+<li>
+Functions <code>table.foreach</code> and <code>table.foreachi</code> are deprecated.
+You can use a for loop with <code>pairs</code> or <code>ipairs</code> instead.
+</li>
+
+<li>
+There were substantial changes in function <a href="#pdf-require"><code>require</code></a> due to
+the new module system.
+However, the new behavior is mostly compatible with the old,
+but <code>require</code> gets the path from <a href="#pdf-package.path"><code>package.path</code></a> instead
+of from <code>LUA_PATH</code>.
+</li>
+
+<li>
+Function <a href="#pdf-collectgarbage"><code>collectgarbage</code></a> has different arguments.
+Function <code>gcinfo</code> is deprecated;
+use <code>collectgarbage("count")</code> instead.
+</li>
+
+</ul>
+
+
+
+
+<h2>7.3 - <a name="7.3">Changes in the API</a></h2>
+<ul>
+
+<li>
+The <code>luaopen_*</code> functions (to open libraries)
+cannot be called directly,
+like a regular C function.
+They must be called through Lua,
+like a Lua function.
+</li>
+
+<li>
+Function <code>lua_open</code> was replaced by <a href="#lua_newstate"><code>lua_newstate</code></a> to
+allow the user to set a memory-allocation function.
+You can use <a href="#luaL_newstate"><code>luaL_newstate</code></a> from the standard library to
+create a state with a standard allocation function
+(based on <code>realloc</code>).
+</li>
+
+<li>
+Functions <code>luaL_getn</code> and <code>luaL_setn</code>
+(from the auxiliary library) are deprecated.
+Use <a href="#lua_objlen"><code>lua_objlen</code></a> instead of <code>luaL_getn</code>
+and nothing instead of <code>luaL_setn</code>.
+</li>
+
+<li>
+Function <code>luaL_openlib</code> was replaced by <a href="#luaL_register"><code>luaL_register</code></a>.
+</li>
+
+<li>
+Function <code>luaL_checkudata</code> now throws an error when the given value
+is not a userdata of the expected type.
+(In Lua&nbsp;5.0 it returned <code>NULL</code>.)
+</li>
+
+</ul>
+
+

+** Implementation of tables (aka arrays, objects, or hash tables).
+** Tables keep its elements in two parts: an array part and a hash part.
+** Non-negative integer keys are all candidates to be kept in the array
+** part. The actual size of the array is the largest `n' such that at
+** least half the slots between 0 and n are in use.
+** Hash uses a mix of chained scatter table with Brent's variation.
+** A main invariant of these tables is that, if an element is not
+** in its main position (i.e. the `original' position that its hash gives
+** to it), then the colliding element is in its own main position.
+** Hence even when the load factor reaches 100%, performance remains good.

+/*
+ * chain.c
+ *
+ * Chainload a hard disk (currently rather braindead.)
+ *
+ * Usage: chain [options]
+ *	  chain hd<disk#> [<partition>] [options]
+ *	  chain fd<disk#> [options]
+ *	  chain mbr:<id> [<partition>] [options]
+ *	  chain guid:<guid> [<partition>] [options]
+ *	  chain label:<label> [<partition>] [options]
+ *	  chain boot [<partition>] [options]
+ *
+ * For example, "chain msdos=io.sys" will load DOS from the current Syslinux
+ * filesystem.  "chain hd0 1" will boot the first partition on the first hard
+ * disk.
+ *
+ * When none of the "hdX", "fdX", "mbr:", "guid:", "label:", "boot" or "fs"
+ * options are specified, the default behaviour is equivalent to "boot".
+ * "boot" means to use the current Syslinux drive, and you can also specify
+ * a partition.
+ *
+ * The mbr: syntax means search all the hard disks until one with a
+ * specific MBR serial number (bytes 440-443) is found.
+ *
+ * Partitions 1-4 are primary, 5+ logical, 0 = boot MBR (default.)
+ *
+ * "fs" will use the current Syslinux filesystem as the boot drive/partition.
+ * When booting from PXELINUX, you will most likely wish to specify a disk.
+ *
+ * Options:
+ *
+ * file=<loader>
+ *	loads the file <loader> **from the Syslinux filesystem**
+ *	instead of loading the boot sector.
+ *
+ * seg=<segment>
+ *	loads at and jumps to <seg>:0000 instead of 0000:7C00.
+ *
+ * isolinux=<loader>
+ *	chainload another version/build of the ISOLINUX bootloader and patch
+ *	the loader with appropriate parameters in memory.
+ *	This avoids the need for the -eltorito-alt-boot parameter of mkisofs,
+ *	when you want more than one ISOLINUX per CD/DVD.
+ *
+ * ntldr=<loader>
+ *	equivalent to seg=0x2000 file=<loader> sethidden,
+ *	used with WinNT's loaders
+ *
+ * cmldr=<loader>
+ *	used with Recovery Console of Windows NT/2K/XP.
+ *	same as ntldr=<loader> & "cmdcons\0" written to
+ *	the system name field in the bootsector
+ *
+ * freedos=<loader>
+ *	equivalent to seg=0x60 file=<loader> sethidden,
+ *	used with FreeDOS' kernel.sys.
+ *
+ * msdos=<loader>
+ * pcdos=<loader>
+ *	equivalent to seg=0x70 file=<loader> sethidden,
+ *	used with DOS' io.sys.
+ *
+ * grub=<loader>
+ *	same as seg=0x800 file=<loader> & jumping to seg 0x820,
+ *	used with GRUB Legacy stage2 files.
+ *
+ * grubcfg=<filename>
+ *	set an alternative config filename in stage2 of Grub Legacy,
+ *	only applicable in combination with "grub=<loader>".
+ *
+ * grldr=<loader>
+ *	pass the partition number to GRUB4DOS,
+ *	used with GRUB4DOS' grldr.
+ *
+ * swap
+ *	if the disk is not fd0/hd0, install a BIOS stub which swaps
+ *	the drive numbers.
+ *
+ * hide
+ *	change type of primary partitions with IDs 01, 04, 06, 07,
+ *	0b, 0c, or 0e to 1x, except for the selected partition, which
+ *	is converted the other way.
+ *
+ * sethidden
+ *	update the "hidden sectors" (partition offset) field in a
+ *	FAT/NTFS boot sector.
+ *
+ * keeppxe
+ *	keep the PXE and UNDI stacks in memory (PXELINUX only).

+ * ifplop.c
+ *
+ * This COM32 module detects if the PLoP Boot Manager was used to boot a CDROM
+ * drive or USB drive, by checking for the presence of the PLoP INT13h hook.
+ *
+ * Usage:    ifplop.c32 [<plop_detected>] -- [<plop_not_detected>]
+ * Examples: ifplop.c32 menu.c32 another.cfg -- plpbt hiddenusb usb1=2
+ *              You need to remove the ".bin" extension of the plpbt.bin file
+ *              if you use it this way.
+ *           ifplop.c32 plop_detected -- plop_not_detected
+ *
+ * A possible config file could be:
+ *
+ * ===========================================================================
+ *  DEFAULT plopcheck
+ *
+ *  # Check for the presence of PLoP (run by default)
+ *  #   When PLoP INT13h hook is found, run the first command (plop_detected)
+ *  #   When PLoP INT13h hook isn't found, run the second command (plop_not_detected)
+ *  LABEL plopcheck
+ *      COM32 ifplop.c32
+ *      APPEND plop_detected -- plop_not_detected
+ *
+ *  # When PLoP INT13h hook was found, boot the menu system.
+ *  # PLoP can have added USB 2.0 speed, so the entries we want to boot
+ *  # will be read from disk much faster (supposing that we have a BIOS
+ *  # that only supports USB 1.1 speed, but a mobo with USB 2.0 controllers).
+ *  LABEL plop_detected
+ *      COM32 menu.c32
+ *      APPEND another.cfg
+ *
+ *  # PLoP INT13h hook wasn't found, so we boot PLoP, so it can add USB 2.0 support
+ *  # When using "LINUX plpbt.bin", you don't need to remove the .bin extension.
+ *  LABEL plop_not_detected
+ *      LINUX plpbt.bin
+ *      APPEND hiddenusb usb1=2
+ *
+ * ===========================================================================
+ *
+ * Why is/can this module be useful?
+ *
+ * You may want to boot PLoP by default from Syslinux when you boot from your
+ * USB stick/drive:
+ *   1. PLoP can upgrade USB 1.1 speed offered by the BIOS to USB 2.0 speed
+ *      if you have USB 2.0 controllers on your mobo.
+ *   2. Some BIOSes only can access the first 128GiB (137GB) on USB drives, while
+ *      internal hard drives don't necessarily suffer from this 128GiB problem.
+ *      Using PLoPs USB capabilities, you can access the whole drive.
+ *
+ * When you select the "USB" entry in PLoP, it will boot your USB stick/drive
+ * again and it will boot PLoP again when you have set booting PLoP as DEFAULT
+ * boot option in your Syslinux configuration file.
+ *
+ * By using ifplop.c32 you can specify which action you want to do the second
+ * time your USB stick/drive is booted. So you can load another config file or
+ * boot a large hard disk image or whatever you want.

+This is a very simple COMBOOT program which can be used to dump memory
+regions over a serial port.  To use it, type on the SYSLINUX command
+line:
+
+memdump <port> <prefix> <start>,<len> <start>,<len>...
+
+For example:
+
+memdump 0 funnysystem- 0,0x600 0x9fc00,0x400 0xf0000,0x10000
+
+... dumps three memory ranges (the standard BIOS memory ranges, often
+useful) onto serial port 0.  The <port> can either be in the range 0-3
+for the standard BIOS serial port, or the I/O address of the UART.
+
+The data is transferred using the YMODEM protocol; the Unix
+implementation of this protocol is called "rb" and is part of the
+"lrzsz" (or "rzsz") package.  If one uses a terminal program like
+Minicom, there is often a way to invoke it from inside the terminal
+program; in Minicom, this is done with the Ctrl-A R control sequence.

+    1.  TOWER OF BABEL
+
+    A "YMODEM Tower of Babel" has descended on the microcomputing community
+    bringing with it confusion, frustration, bloated phone bills, and wasted
+    man hours.  Sadly, I (Chuck Forsberg) am partly to blame for this mess.
+
+    As author of the early 1980s batch and 1k XMODEM extensions, I assumed
+    readers of earlier versions of this document would implement as much of
+    the YMODEM protocol as their programming skills and computing environments
+    would permit.  This proved a rather naive assumption as programmers
+    motivated by competitive pressure implemented as little of YMODEM as
+    possible.  Some have taken whatever parts of YMODEM that appealed to them,
+    applied them to MODEM7 Batch, Telink, XMODEM or whatever, and called the
+    result YMODEM.
+
+    Jeff Garbers (Crosstalk package development director) said it all: "With
+    protocols in the public domain, anyone who wants to dink around with them
+    can go ahead." [1]
+
+    Documents containing altered examples derived from YMODEM.DOC have added
+    to the confusion.  In one instance, some self styled rewriter of history
+    altered the heading in YMODEM.DOC's Figure 1 from "1024 byte Packets" to
+    "YMODEM/CRC File Transfer Protocol".  None of the XMODEM and YMODEM
+    examples shown in that document were correct.
+
+    To put an end to this confusion, we must make "perfectly clear" what
+    YMODEM stands for, as Ward Christensen defined it in his 1985 coining of
+    the term.
+
+    To the majority of you who read, understood, and respected Ward's
+    definition of YMODEM, I apologize for the inconvenience.
+
+    1.1  Definitions
+
+    ARC     ARC is a program that compresses one or more files into an archive
+            and extracts files from such archives.
+
+    XMODEM  refers to the file transfer etiquette introduced by Ward
+            Christensen's 1977 MODEM.ASM program.  The name XMODEM comes from
+            Keith Petersen's XMODEM.ASM program, an adaptation of MODEM.ASM
+            for Remote CP/M (RCPM) systems.  It's also called the MODEM or
+            MODEM2 protocol.  Some who are unaware of MODEM7's unusual batch
+            file mode call it MODEM7.  Other aliases include "CP/M Users'
+            Group" and "TERM II FTP 3".  The name XMODEM caught on partly
+            because it is distinctive and partly because of media interest in

+            communications program because of its universality, simplicity,
+            and reasonable performance.
+
+    XMODEM/CRC replaces XMODEM's 1 byte checksum with a two byte Cyclical

+    2.  YMODEM MINIMUM REQUIREMENTS
+
+    All programs claiming to support YMODEM must meet the following minimum
+    requirements:
+
+       + The sending program shall send the pathname (file name) in block 0.
+
+       + The pathname shall be a null terminated ASCII string as described
+         below.
+
+         For those who are too lazy to read the entire document:
+
+            + Unless specifically requested, only the file name portion is
+              sent.
+
+            + No drive letter is sent.
+
+            + Systems that do not distinguish between upper and lower case
+              letters in filenames shall send the pathname in lower case only.
+
+
+       + The receiving program shall use this pathname for the received file
+         name, unless explicitly overridden.
+
+       + When the receiving program receives this block and successfully
+         opened the output file, it shall acknowledge this block with an ACK
+         character and then proceed with a normal XMODEM file transfer
+         beginning with a "C" or NAK tranmsitted by the receiver.
+
+       + The sending program shall use CRC-16 in response to a "C" pathname
+         nak, otherwise use 8 bit checksum.
+
+       + The receiving program must accept any mixture of 128 and 1024 byte
+         blocks within each file it receives.  Sending programs may
+         arbitrarily switch between 1024 and 128 byte blocks.
+
+       + The sending program must not change the length of an unacknowledged
+         block.
+
+       + At the end of each file, the sending program shall send EOT up to ten
+         times until it receives an ACK character.  (This is part of the
+         XMODEM spec.)
+
+       + The end of a transfer session shall be signified by a null (empty)
+         pathname, this pathname block shall be acknowledged the same as other
+         pathname blocks.
+
+    Programs not meeting all of these requirements are not YMODEM compatible,
+    and shall not be described as supporting YMODEM.
+
+    Meeting these MINIMUM requirements does not guarantee reliable file

+    3.  WHY YMODEM?
+
+    Since its development half a decade ago, the Ward Christensen modem
+    protocol has enabled a wide variety of computer systems to interchange
+    data.  There is hardly a communications program that doesn't at least
+    claim to support this protocol.
+
+    Advances in computing, modems and networking have revealed a number of
+    weaknesses in the original protocol:
+
+       + The short block length caused throughput to suffer when used with
+         timesharing systems, packet switched networks, satellite circuits,
+         and buffered (error correcting) modems.
+
+       + The 8 bit arithmetic checksum and other aspects allowed line
+         impairments to interfere with dependable, accurate transfers.
+
+       + Only one file could be sent per command.  The file name had to be
+         given twice, first to the sending program and then again to the
+         receiving program.
+
+       + The transmitted file could accumulate as many as 127 extraneous
+         bytes.
+
+       + The modification date of the file was lost.
+
+    A number of other protocols have been developed over the years, but none
+    have displaced XMODEM to date:
+
+       + Lack of public domain documentation and example programs have kept
+         proprietary protocols such as Blast, Relay, and others tightly bound
+         to the fortunes of their suppliers.
+
+       + Complexity discourages the widespread application of BISYNC, SDLC,
+         HDLC, X.25, and X.PC protocols.
+
+       + Performance compromises and complexity have limited the popularity of
+         the Kermit protocol, which was developed to allow file transfers in
+         environments hostile to XMODEM.
+
+    The XMODEM protocol extensions and YMODEM Batch address some of these
+    weaknesses while maintaining most of XMODEM's simplicity.
+
+    YMODEM is supported by the public domain programs YAM (CP/M),
+    YAM(CP/M-86), YAM(CCPM-86), IMP (CP/M), KMD (CP/M), rz/sz (Unix, Xenix,
+    VMS, Berkeley Unix, Venix, Xenix, Coherent, IDRIS, Regulus).  Commercial
+    implementations include MIRROR, and Professional-YAM.[1] Communications

+
+
+
+    programs supporting these extensions have been in use since 1981.
+
+    The 1k block length (XMODEM-1k) described below may be used in conjunction
+    with YMODEM Batch Protocol, or with single file transfers identical to the
+    XMODEM/CRC protocol except for minimal changes to support 1k blocks.
+
+    Another extension is the YMODEM-g protocol.  YMODEM-g provides batch
+    transfers with maximum throughput when used with end to end error
+    correcting media, such as X.PC and error correcting modems, including 9600
+    bps units by TeleBit, U.S.Robotics, Hayes, Electronic Vaults, Data Race,
+    and others.
+
+    To complete this tome, edited versions of Ward Christensen's original
+    protocol document and John Byrns's CRC-16 document are included for
+    reference.
+
+    References to the MODEM or MODEM7 protocol have been changed to XMODEM to
+    accommodate the vernacular.  In Australia, it is properly called the
+    Christensen Protocol.

+    I think its time for me to
+
+    (1) document it; (people call me and say "my product is going to include
+    it - what can I 'reference'", or "I'm writing a paper on it, what do I put
+    in the bibliography") and
+
+    (2) propose an "incremental extension" to it, which might take "exactly"
+    the form of Chuck Forsberg's YAM protocol.  He wrote YAM in C for CP/M and
+    put it in the public domain, and wrote a batch protocol for Unix[4] called
+    rb and sb (receive batch, send batch), which was basically XMODEM with
+       (a) a record 0 containing filename date time and size
+       (b) a 1K block size option
+       (c) CRC-16.
+
+    He did some clever programming to detect false ACK or EOT, but basically
+    left them the same.
+
+    People who suggest I make SIGNIFICANT changes to the protocol, such as
+    "full duplex", "multiple outstanding blocks", "multiple destinations", etc
+    etc don't understand that the incredible simplicity of the protocol is one
+    of the reasons it survived to this day in as many machines and programs as
+    it may be found in!
+
+    Consider the PC-NET group back in '77 or so - documenting to beat the band
+    - THEY had a protocol, but it was "extremely complex", because it tried to
+    be "all things to all people" - i.e. send binary files on a 7-bit system,
+    etc.  I was not that "benevolent". I (emphasize > I < ) had an 8-bit UART,
+    so "my protocol was an 8-bit protocol", and I would just say "sorry" to
+    people who were held back by 7-bit limitations.  ...
+
+    Block size: Chuck Forsberg created an extension of my protocol, called
+    YAM, which is also supported via his public domain programs for UNIX
+    called rb and sb - receive batch and send batch.  They cleverly send a
+    "block 0" which contains the filename, date, time, and size.
+    Unfortunately, its UNIX style, and is a bit weird[5] - octal numbers, etc.
+    BUT, it is a nice way to overcome the kludgy "echo the chars of the name"
+    introduced with MODEM7.  Further, chuck uses CRC-16 and optional 1K
+    blocks.  Thus the record 0, 1K, and CRC, make it a "pretty slick new
+    protocol" which is not significantly different from my own.
+
+    Also, there is a catchy name - YMODEM.  That means to some that it is the
+    "next thing after XMODEM", and to others that it is the Y(am)MODEM
+

+
+     5. The file length, time, and file mode are optional.  The pathname and
+        file length may be sent alone if desired.

+    protocol.  I don't want to emphasize that too much - out of fear that
+    other mfgrs might think it is a "competitive" protocol, rather than an
+    "unaffiliated" protocol.  Chuck is currently selling a much-enhanced
+    version of his CP/M-80 C program YAM, calling it Professional Yam, and its
+    for the PC - I'm using it right now.  VERY slick!  32K capture buffer,

+    for just about everything - directory (sorted every which way), XMODEM,
+    YMODEM, KERMIT, and ASCII file upload/download, etc.  You can program it
+    to "behave" with most any system - for example when trying a number for
+    CIS it detects the "busy" string back from the modem and substitutes a
+    diff phone # into the dialing string and branches back to try it.

+
+    4.  XMODEM PROTOCOL ENHANCEMENTS
+
+    This chapter discusses the protocol extensions to Ward Christensen's 1982
+    XMODEM protocol description document.
+
+    The original document recommends the user be asked whether to continue
+    trying or abort after 10 retries.  Most programs no longer ask the
+    operator whether he wishes to keep retrying.  Virtually all correctable
+    errors are corrected within the first few retransmissions.  If the line is
+    so bad that ten attempts are insufficient, there is a significant danger
+    of undetected errors.  If the connection is that bad, it's better to
+    redial for a better connection, or mail a floppy disk.
+
+
+    4.1  Graceful Abort
+
+    The YAM and Professional-YAM X/YMODEM routines recognize a sequence of two
+    consecutive CAN (Hex 18) characters without modem errors (overrun,
+    framing, etc.) as a transfer abort command.  This sequence is recognized
+    when is waiting for the beginning of a block or for an acknowledgement to
+    a block that has been sent.  The check for two consecutive CAN characters
+    reduces the number of transfers aborted by line hits.  YAM sends eight CAN
+    characters when it aborts an XMODEM, YMODEM, or ZMODEM protocol file
+    transfer.  Pro-YAM then sends eight backspaces to delete the CAN
+    characters from the remote's keyboard input buffer, in case the remote had
+    already aborted the transfer and was awaiting a keyboarded command.
+
+
+    4.2  CRC-16 Option
+
+    The XMODEM protocol uses an optional two character CRC-16 instead of the
+    one character arithmetic checksum used by the original protocol and by
+    most commercial implementations.  CRC-16 guarantees detection of all
+    single and double bit errors,  all errors with an odd number of error
+    bits, all burst errors of length 16 or less, 99.9969% of all 17-bit error
+    bursts, and 99.9984 per cent of all possible longer error bursts.  By
+    contrast, a double bit error, or a burst error of 9 bits or more can sneak
+    past the XMODEM protocol arithmetic checksum.
+
+    The XMODEM/CRC protocol is similar to the XMODEM protocol, except that the
+    receiver specifies CRC-16 by sending C (Hex 43) instead of NAK when
+    requesting the FIRST block.  A two byte CRC is sent in place of the one
+    byte arithmetic checksum.
+
+    YAM's c option to the r command enables CRC-16 in single file reception,
+    corresponding to the original implementation in the MODEM7 series
+    programs.  This remains the default because many commercial communications
+    programs and bulletin board systems still do not support CRC-16,
+    especially those written in Basic or Pascal.
+
+    XMODEM protocol with CRC is accurate provided both sender and receiver

+
+
+
+    both report a successful transmission.  The protocol is robust in the
+    presence of characters lost by buffer overloading on timesharing systems.
+
+    The single character ACK/NAK responses generated by the receiving program
+    adapt well to split speed modems, where the reverse channel is limited to
+    ten per cent or less of the main channel's speed.
+
+    XMODEM and YMODEM are half duplex protocols which do not attempt to
+    transmit information and control signals in both directions at the same
+    time.  This avoids buffer overrun problems that have been reported by
+    users attempting to exploit full duplex asynchronous file transfer
+    protocols such as Blast.
+
+    Professional-YAM adds several proprietary logic enhancements to XMODEM's
+    error detection and recovery.  These compatible enhancements eliminate
+    most of the bad file transfers other programs make when using the XMODEM
+    protocol under less than ideal conditions.
+
+
+    4.3  XMODEM-1k 1024 Byte Block
+
+    Disappointing throughput downloading from Unix with YMODEM[1] lead to the
+    development of 1024 byte blocks in 1982.  1024 byte blocks reduce the
+    effect of delays from timesharing systems, modems, and packet switched
+    networks on throughput by 87.5 per cent in addition to decreasing XMODEM's
+    3 per cent overhead (block number, CRC, etc.).
+
+    Some environments cannot accept 1024 byte bursts, including some networks
+    and minicomputer ports.  The longer block length should be an option.
+
+    The choice to use 1024 byte blocks is expressed to the sending program on
+    its command line or selection menu.[2] 1024 byte blocks improve throughput
+    in many applications.
+
+    An STX (02) replaces the SOH (01) at the beginning of the transmitted
+    block to notify the receiver of the longer block length.  The transmitted
+    block contains 1024 bytes of data.  The receiver should be able to accept
+    any mixture of 128 and 1024 byte blocks.  The block number (in the second
+    and third bytes of the block) is incremented by one for each block
+    regardless of the block length.
+
+    The sender must not change between 128 and 1024 byte block lengths if it
+    has not received a valid ACK for the current block.  Failure to observe

+    this restriction allows transmission errors to pass undetected.
+
+    If 1024 byte blocks are being used, it is possible for a file to "grow" up
+    to the next multiple of 1024 bytes.  This does not waste disk space if the
+    allocation granularity is 1k or greater.  With YMODEM batch transmission,
+    the optional file length transmitted in the file name block allows the
+    receiver to discard the padding, preserving the exact file length and
+    contents.
+
+    1024 byte blocks may be used with batch file transmission or with single
+    file transmission.  CRC-16 should be used with the k option to preserve
+    data integrity over phone lines.  If a program wishes to enforce this
+    recommendation, it should cancel the transfer, then issue an informative
+    diagnostic message if the receiver requests checksum instead of CRC-16.
+
+    Under no circumstances may a sending program use CRC-16 unless the
+    receiver commands CRC-16.

+    5.  YMODEM Batch File Transmission
+
+    The YMODEM Batch protocol is an extension to the XMODEM/CRC protocol that
+    allows 0 or more files to be transmitted with a single command.  (Zero
+    files may be sent if none of the requested files is accessible.) The
+    design approach of the YMODEM Batch protocol is to use the normal routines
+    for sending and receiving XMODEM blocks in a layered fashion similar to
+    packet switching methods.
+
+    Why was it necessary to design a new batch protocol when one already
+    existed in MODEM7?[1] The batch file mode used by MODEM7 is unsuitable
+    because it does not permit full pathnames, file length, file date, or
+    other attribute information to be transmitted.  Such a restrictive design,
+    hastily implemented with only CP/M in mind, would not have permitted
+    extensions to current areas of personal computing such as Unix, DOS, and
+    object oriented systems.  In addition, the MODEM7 batch file mode is
+    somewhat susceptible to transmission impairments.
+
+    As in the case of single a file transfer, the receiver initiates batch
+    file transmission by sending a "C" character (for CRC-16).
+
+    The sender opens the first file and sends block number 0 with the
+    following information.[2]
+
+    Only the pathname (file name) part is required for batch transfers.
+
+    To maintain upwards compatibility, all unused bytes in block 0 must be set
+    to null.
+
+    Pathname The pathname (conventionally, the file name) is sent as a null
+         terminated ASCII string.  This is the filename format used by the
+         handle oriented MSDOS(TM) functions and C library fopen functions.
+         An assembly language example follows:
+                                  DB      'foo.bar',0
+         No spaces are included in the pathname.  Normally only the file name
+         stem (no directory prefix) is transmitted unless the sender has
+         selected YAM's f option to send the full pathname.  The source drive
+         (A:, B:, etc.) is not sent.
+
+         Filename Considerations:
+
+
+
+    __________
+
+     1. The MODEM7 batch protocol transmitted CP/M FCB bytes f1...f8 and
+        t1...t3 one character at a time.  The receiver echoed these bytes as
+        received, one at a time.
+
+     2. Only the data part of the block is described here.

+
+
+
+            + File names are forced to lower case unless the sending system
+              supports upper/lower case file names.  This is a convenience for
+              users of systems (such as Unix) which store filenames in upper
+              and lower case.
+
+            + The receiver should accommodate file names in lower and upper
+              case.
+
+            + When transmitting files between different operating systems,
+              file names must be acceptable to both the sender and receiving
+              operating systems.
+
+         If directories are included, they are delimited by /; i.e.,
+         "subdir/foo" is acceptable, "subdir\foo" is not.
+
+    Length The file length and each of the succeeding fields are optional.[3]
+         The length field is stored in the block as a decimal string counting
+         the number of data bytes in the file.  The file length does not
+         include any CPMEOF (^Z) or other garbage characters used to pad the
+         last block.
+
+         If the file being transmitted is growing during transmission, the
+         length field should be set to at least the final expected file
+         length, or not sent.
+
+         The receiver stores the specified number of characters, discarding
+         any padding added by the sender to fill up the last block.
+
+    Modification Date The mod date is optional, and the filename and length
+         may be sent without requiring the mod date to be sent.
+
+         Iff the modification date is sent, a single space separates the
+         modification date from the file length.
+
+         The mod date is sent as an octal number giving the time the contents
+         of the file were last changed, measured in seconds from Jan 1 1970
+         Universal Coordinated Time (GMT).  A date of 0 implies the
+         modification date is unknown and should be left as the date the file
+         is received.
+
+         This standard format was chosen to eliminate ambiguities arising from
+         transfers between different time zones.

+
+
+
+    Mode Iff the file mode is sent, a single space separates the file mode
+         from the modification date.  The file mode is stored as an octal
+         string.  Unless the file originated from a Unix system, the file mode
+         is set to 0.  rb(1) checks the file mode for the 0x8000 bit which
+         indicates a Unix type regular file.  Files with the 0x8000 bit set
+         are assumed to have been sent from another Unix (or similar) system
+         which uses the same file conventions.  Such files are not translated
+         in any way.
+
+
+    Serial Number Iff the serial number is sent, a single space separates the
+         serial number from the file mode.  The serial number of the
+         transmitting program is stored as an octal string.  Programs which do
+         not have a serial number should omit this field, or set it to 0.  The
+         receiver's use of this field is optional.
+
+
+    Other Fields YMODEM was designed to allow additional header fields to be
+         added as above without creating compatibility problems with older
+         YMODEM programs.  Please contact Omen Technology if other fields are
+         needed for special application requirements.
+
+    The rest of the block is set to nulls.  This is essential to preserve
+    upward compatibility.[4]
+
+    If the filename block is received with a CRC or other error, a
+    retransmission is requested.  After the filename block has been received,
+    it is ACK'ed if the write open is successful.  If the file cannot be
+    opened for writing, the receiver cancels the transfer with CAN characters
+    as described above.
+
+    The receiver then initiates transfer of the file contents with a "C"
+    character, according to the standard XMODEM/CRC protocol.
+
+    After the file contents and XMODEM EOT have been transmitted and
+    acknowledged, the receiver again asks for the next pathname.
+
+    Transmission of a null pathname terminates batch file transmission.
+
+    Note that transmission of no files is not necessarily an error.  This is
+    possible if none of the files requested of the sender could be opened for
+    reading.
+
+
+
+    __________
+
+     4. If, perchance, this information extends beyond 128 bytes (possible
+        with Unix 4.2 BSD extended file names), the block should be sent as a
+        1k block as described above.

+    Most YMODEM receivers request CRC-16 by default.

+
+    KMD and IMP use a "CK" character sequence emitted by the receiver to
+    trigger the use of 1024 byte blocks as an alternative to specifying this
+    option to the sending program.  This two character sequence generally

+    herein.  Programs with marginal XMODEM implementations do not fare so
+    well.  Timesharing systems and packet switched networks can separate the
+    successive characters, rendering this method unreliable.
+
+    Sending programs may detect the CK sequence if the operating enviornment
+    does not preclude reliable implementation.
+
+    Instead of the standard YMODEM file length in decimal, KMD and IMP
+    transmit the CP/M record count in the last two bytes of the header block.

+
+    6.  YMODEM-g File Transmission
+
+    Developing technology is providing phone line data transmission at ever
+    higher speeds using very specialized techniques.  These high speed modems,
+    as well as session protocols such as X.PC, provide high speed, nearly
+    error free communications at the expense of considerably increased delay
+    time.
+
+    This delay time is moderate compared to human interactions, but it
+    cripples the throughput of most error correcting protocols.
+
+    The g option to YMODEM has proven effective under these circumstances.
+    The g option is driven by the receiver, which initiates the batch transfer
+    by transmitting a G instead of C.  When the sender recognizes the G, it
+    bypasses the usual wait for an ACK to each transmitted block, sending
+    succeeding blocks at full speed, subject to XOFF/XON or other flow control
+    exerted by the medium.
+
+    The sender expects an inital G to initiate the transmission of a
+    particular file, and also expects an ACK on the EOT sent at the end of
+    each file.  This synchronization allows the receiver time to open and

+
+    If an error is detected in a YMODEM-g transfer, the receiver aborts the
+    transfer with the multiple CAN abort sequence.  The ZMODEM protocol should
+    be used in applications that require both streaming throughput and error

+      <can> 18H

+
+
+    7.2  Transmission Medium Level Protocol
+
+    Asynchronous, 8 data bits, no parity, one stop bit.
+
+    The protocol imposes no restrictions on the contents of the data being
+    transmitted.  No control characters are looked for in the 128-byte data
+    messages.  Absolutely any kind of data may be sent - binary, ASCII, etc.
+    The protocol has not formally been adopted to a 7-bit environment for the
+    transmission of ASCII-only (or unpacked-hex) data , although it could be
+    simply by having both ends agree to AND the protocol-dependent data with
+    7F hex before validating it.  I specifically am referring to the checksum,
+    and the block numbers and their ones- complement.
+
+    Those wishing to maintain compatibility of the CP/M file structure, i.e.
+    to allow modemming ASCII files to or from CP/M systems should follow this
+    data format:
+
+       + ASCII tabs used (09H); tabs set every 8.
+
+       + Lines terminated by CR/LF (0DH 0AH)
+
+       + End-of-file indicated by ^Z, 1AH.  (one or more)
+
+       + Data is variable length, i.e. should be considered a continuous
+         stream of data bytes, broken into 128-byte chunks purely for the
+         purpose of transmission.
+
+       + A CP/M "peculiarity": If the data ends exactly on a 128-byte
+         boundary, i.e. CR in 127, and LF in 128, a subsequent sector
+         containing the ^Z EOF character(s) is optional, but is preferred.
+         Some utilities or user programs still do not handle EOF without ^Zs.

+
+
+
+       + The last block sent is no different from others, i.e.  there is no
+         "short block".
+                  Figure 9.  XMODEM Message Block Level Protocol
+
+    Each block of the transfer looks like:
+          <SOH><blk #><255-blk #><--128 data bytes--><cksum>
+    in which:
+    <SOH>         = 01 hex
+    <blk #>       = binary number, starts at 01 increments by 1, and
+                    wraps 0FFH to 00H (not to 01)
+    <255-blk #>   = blk # after going thru 8080 "CMA" instr, i.e.
+                    each bit complemented in the 8-bit block number.
+                    Formally, this is the "ones complement".
+    <cksum>       = the sum of the data bytes only.  Toss any carry.
+
+    7.3  File Level Protocol
+
+    7.3.1  Common_to_Both_Sender_and_Receiver
+    All errors are retried 10 times.  For versions running with an operator
+    (i.e. NOT with XMODEM), a message is typed after 10 errors asking the
+    operator whether to "retry or quit".
+
+    Some versions of the protocol use <can>, ASCII ^X, to cancel transmission.
+    This was never adopted as a standard, as having a single "abort" character
+    makes the transmission susceptible to false termination due to an <ack>
+    <nak> or <soh> being corrupted into a <can> and aborting transmission.
+
+    The protocol may be considered "receiver driven", that is, the sender need
+    not automatically re-transmit, although it does in the current
+    implementations.
+
+
+    7.3.2  Receive_Program_Considerations
+    The receiver has a 10-second timeout.  It sends a <nak> every time it
+    times out.  The receiver's first timeout, which sends a <nak>, signals the
+    transmitter to start.  Optionally, the receiver could send a <nak>
+    immediately, in case the sender was ready.  This would save the initial 10
+    second timeout.  However, the receiver MUST continue to timeout every 10
+    seconds in case the sender wasn't ready.
+
+    Once into a receiving a block, the receiver goes into a one-second timeout
+    for each character and the checksum.  If the receiver wishes to <nak> a
+    block for any reason (invalid header, timeout receiving data), it must
+    wait for the line to clear.  See "programming tips" for ideas
+
+    Synchronizing:  If a valid block number is received, it will be: 1) the
+    expected one, in which case everything is fine; or 2) a repeat of the
+    previously received block.  This should be considered OK, and only
+    indicates that the receivers <ack> got glitched, and the sender re-
+    transmitted; 3) any other block number indicates a fatal loss of
+    synchronization, such as the rare case of the sender getting a line-glitch

+
+
+    that looked like an <ack>.  Abort the transmission, sending a <can>
+
+
+    7.3.3  Sending_program_considerations
+    While waiting for transmission to begin, the sender has only a single very
+    long timeout, say one minute.  In the current protocol, the sender has a
+    10 second timeout before retrying.  I suggest NOT doing this, and letting
+    the protocol be completely receiver-driven.  This will be compatible with
+    existing programs.
+
+    When the sender has no more data, it sends an <eot>, and awaits an <ack>,
+    resending the <eot> if it doesn't get one.  Again, the protocol could be
+    receiver-driven, with the sender only having the high-level 1-minute
+    timeout to abort.
+
+
+    Here is a sample of the data flow, sending a 3-block message.  It includes
+    the two most common line hits - a garbaged block, and an <ack> reply
+    getting garbaged.  <xx> represents the checksum byte.

+                                  <---              <nak>

+    <soh> 02 FD -data- xx         --->

+    <eot>                         --->
+                                  <---              <ack>
+    (finished)
+
+    7.4  Programming Tips
+
+       + The character-receive subroutine should be called with a parameter
+         specifying the number of seconds to wait.  The receiver should first
+         call it with a time of 10, then <nak> and try again, 10 times.
+
+         After receiving the <soh>, the receiver should call the character
+         receive subroutine with a 1-second timeout, for the remainder of the
+         message and the <cksum>.  Since they are sent as a continuous stream,
+         timing out of this implies a serious like glitch that caused, say,
+         127 characters to be seen instead of 128.

+
+
+
+       + When the receiver wishes to <nak>, it should call a "PURGE"
+         subroutine, to wait for the line to clear.  Recall the sender tosses
+         any characters in its UART buffer immediately upon completing sending
+         a block, to ensure no glitches were mis- interpreted.
+
+         The most common technique is for "PURGE" to call the character
+         receive subroutine, specifying a 1-second timeout,[1] and looping
+         back to PURGE until a timeout occurs.  The <nak> is then sent,
+         ensuring the other end will see it.
+
+       + You may wish to add code recommended by John Mahr to your character
+         receive routine - to set an error flag if the UART shows framing
+         error, or overrun.  This will help catch a few more glitches - the
+         most common of which is a hit in the high bits of the byte in two
+         consecutive bytes.  The <cksum> comes out OK since counting in 1-byte
+         produces the same result of adding 80H + 80H as with adding 00H +
+         00H.

+    885-1105.
+
+    The CRC used in the Modem Protocol is an alternate form of block check
+    which provides more robust error detection than the original checksum.
+    Andrew S. Tanenbaum says in his book, Computer Networks, that the CRC-
+    CCITT used by the Modem Protocol will detect all single and double bit
+    errors, all errors with an odd number of bits, all burst errors of length
+    16 or less, 99.997% of 17-bit error bursts, and 99.998% of 18-bit and
+    longer bursts.[1]
+
+    The changes to the Modem Protocol to replace the checksum with the CRC are
+    straight forward. If that were all that we did we would not be able to
+    communicate between a program using the old checksum protocol and one
+    using the new CRC protocol. An initial handshake was added to solve this
+    problem. The handshake allows a receiving program with CRC capability to
+    determine whether the sending program supports the CRC option, and to
+    switch it to CRC mode if it does. This handshake is designed so that it
+    will work properly with programs which implement only the original
+    protocol. A description of this handshake is presented in section 10.
+
+                Figure 11.  Message Block Level Protocol, CRC mode
+
+    Each block of the transfer in CRC mode looks like:
+         <SOH><blk #><255-blk #><--128 data bytes--><CRC hi><CRC lo>
+    in which:
+    <SOH>        = 01 hex
+    <blk #>      = binary number, starts at 01 increments by 1, and
+                   wraps 0FFH to 00H (not to 01)
+    <255-blk #>  = ones complement of blk #.
+    <CRC hi>     = byte containing the 8 hi order coefficients of the CRC.
+    <CRC lo>     = byte containing the 8 lo order coefficients of the CRC.
+
+    8.1  CRC Calculation
+
+    8.1.1  Formal_Definition
+    To calculate the 16 bit CRC the message bits are considered to be the
+    coefficients of a polynomial. This message polynomial is first multiplied
+    by X^16 and then divided by the generator polynomial (X^16 + X^12 + X^5 +
+
+
+    __________
+
+     1. This reliability figure is misleading because XMODEM's critical
+        supervisory functions are not protected by this CRC.

+    1) using modulo two arithmetic. The remainder left after the division is
+    the desired CRC. Since a message block in the Modem Protocol is 128 bytes
+    or 1024 bits, the message polynomial will be of order X^1023. The hi order
+    bit of the first byte of the message block is the coefficient of X^1023 in
+    the message polynomial.  The lo order bit of the last byte of the message
+    block is the coefficient of X^0 in the message polynomial.

+    8.2  CRC File Level Protocol Changes
+
+    8.2.1  Common_to_Both_Sender_and_Receiver
+    The only change to the File Level Protocol for the CRC option is the
+    initial handshake which is used to determine if both the sending and the
+    receiving programs support the CRC mode. All Modem Programs should support
+    the checksum mode for compatibility with older versions.  A receiving
+    program that wishes to receive in CRC mode implements the mode setting
+    handshake by sending a <C> in place of the initial <nak>.  If the sending
+    program supports CRC mode it will recognize the <C> and will set itself
+    into CRC mode, and respond by sending the first block as if a <nak> had
+    been received. If the sending program does not support CRC mode it will
+    not respond to the <C> at all. After the receiver has sent the <C> it will
+    wait up to 3 seconds for the <soh> that starts the first block. If it
+    receives a <soh> within 3 seconds it will assume the sender supports CRC
+    mode and will proceed with the file exchange in CRC mode. If no <soh> is

+
+
+
+    received within 3 seconds the receiver will switch to checksum mode, send
+    a <nak>, and proceed in checksum mode. If the receiver wishes to use
+    checksum mode it should send an initial <nak> and the sending program
+    should respond to the <nak> as defined in the original Modem Protocol.
+    After the mode has been set by the initial <C> or <nak> the protocol
+    follows the original Modem Protocol and is identical whether the checksum
+    or CRC is being used.
+
+
+    8.2.2  Receive_Program_Considerations
+    There are at least 4 things that can go wrong with the mode setting
+    handshake.
+
+      1.  the initial <C> can be garbled or lost.
+
+      2.  the initial <soh> can be garbled.
+
+      3.  the initial <C> can be changed to a <nak>.
+
+      4.  the initial <nak> from a receiver which wants to receive in checksum
+          can be changed to a <C>.
+
+    The first problem can be solved if the receiver sends a second <C> after
+    it times out the first time. This process can be repeated several times.
+    It must not be repeated too many times before sending a <nak> and
+    switching to checksum mode or a sending program without CRC support may
+    time out and abort. Repeating the <C> will also fix the second problem if
+    the sending program cooperates by responding as if a <nak> were received
+    instead of ignoring the extra <C>.
+
+    It is possible to fix problems 3 and 4 but probably not worth the trouble
+    since they will occur very infrequently. They could be fixed by switching
+    modes in either the sending or the receiving program after a large number
+    of successive <nak>s. This solution would risk other problems however.
+
+
+    8.2.3  Sending_Program_Considerations
+    The sending program should start in the checksum mode. This will insure
+    compatibility with checksum only receiving programs. Anytime a <C> is
+    received before the first <nak> or <ack> the sending program should set
+    itself into CRC mode and respond as if a <nak> were received. The sender
+    should respond to additional <C>s as if they were <nak>s until the first
+    <ack> is received. This will assist the receiving program in determining
+    the correct mode when the <soh> is lost or garbled. After the first <ack>
+    is received the sending program should ignore <C>s.

+
+    Here is a data flow example for the case where the receiver requests
+    transmission in the CRC mode but the sender does not support the CRC
+    option. This example also includes various transmission errors.  <xx>
+    represents the checksum byte.

+    of this document.
+
+
+    9.1  TeleGodzilla Bulletin Board
+
+    More information may be obtained by calling TeleGodzilla at 503-621-3746.
+    Speed detection is automatic for 1200, 2400 and 19200(Telebit PEP) bps.
+    TrailBlazer modem users may issue the TeleGodzilla trailblazer command to
+    swith to 19200 bps once they have logged in.
+
+    Interesting files include RZSZ.ZOO (C source code), YZMODEM.ZOO (Official
+    XMODEM, YMODEM, and ZMODEM protocol descriptions), ZCOMMEXE.ARC,
+    ZCOMMDOC.ARC, and ZCOMMHLP.ARC (PC-DOS shareware comm program with XMODEM,
+    True YMODEM(TM), ZMODEM, Kermit Sliding Windows, Telink, MODEM7 Batch,
+    script language, etc.).
+
+
+    9.2  Unix UUCP Access
+
+    UUCP sites can obtain the current version of this file with
+                     uucp omen!/u/caf/public/ymodem.doc /tmp
+    A continually updated list of available files is stored in
+    /usr/spool/uucppublic/FILES.  When retrieving these files with uucp,
+    remember that the destination directory on your system must be writeable
+    by anyone, or the UUCP transfer will fail.
+
+    The following L.sys line calls TeleGodzilla (Pro-YAM in host operation).
+    TeleGodzilla determines the incoming speed automatically.
+
+    In response to "Name Please:" uucico gives the Pro-YAM "link" command as a
+    user name.  The password (Giznoid) controls access to the Xenix system
+    connected to the IBM PC's other serial port.  Communications between
+    Pro-YAM and Xenix use 9600 bps; YAM converts this to the caller's speed.
+
+    Finally, the calling uucico logs in as uucp.

+
+    ZCOMM, A shareware little brother to Professional-YAM, is available as
+    ZCOMMEXE.ARC on TeleGodzilla and other bulletin board systems.  ZCOMM may
+    be used to test YMODEM amd ZMODEM implementations.
+
+    Unix programs supporting YMODEM are available on TeleGodzilla in RZSZ.ZOO.
+    This ZOO archive includes a ZCOMM/Pro-YAM/PowerCom script ZUPL.T to upload
+    a bootstrap program MINIRB.C, compile it, and then upload the rest of the
+    files using the compiled MINIRB.  Most Unix like systems are supported,
+    including V7, Xenix, Sys III, 4.2 BSD, SYS V, Idris, Coherent, and
+    Regulus.
+
+    A version for VAX-VMS is available in VRBSB.SHQ.
+
+    Irv Hoff has added 1k blocks and basic YMODEM batch transfers to the KMD
+    and IMP series programs, which replace the XMODEM and MODEM7/MDM7xx series
+    respectively.  Overlays are available for a wide variety of CP/M systems.

+    Unlike ZMODEM and Kermit, XMODEM and YMODEM place obstacles in the path of
+    a reliable high performance implementation, evidenced by poor reliability
+    under stress of the industry leaders' XMODEM and YMODEM programs.  Omen
+    Technology provides consulting and other services to those wishing to

+ * getfssec.c
+ *
+ * Generic getfssec implementation for disk-based filesystems, which
+ * support the next_extent() method.
+ *
+ * The expected semantics of next_extent are as follows:
+ *
+ * The second argument will contain the initial sector number to be
+ * mapped.  The routine is expected to populate
+ * inode->next_extent.pstart and inode->next_extent.len (the caller
+ * will store the initial sector number into inode->next_extent.lstart
+ * on return.)
+ *
+ * If inode->next_extent.len != 0 on entry then the routine is allowed
+ * to assume inode->next_extent contains valid data from the previous
+ * usage, which can be used for optimization purposes.
+ *
+ * If the filesystem can map the entire file as a single extent
+ * (e.g. iso9660), then the filesystem can simply insert the extent
+ * information into inode->next_extent at searchdir/iget time, and leave
+ * next_extent() as NULL.
+ *
+ * Note: the filesystem driver is not required to do extent coalescing,
+ * if that is difficult to do; this routine will perform extent lookahead
+ * and coalescing.

+;; There is a problem with certain versions of the AWARD BIOS ...

+;;	pushf
+;;	call	<direct far>
+;;
+;; and use <direct far> as the new vector for int 13. The code above is
+;; used to load the boot code into ram, and there should be no reason

+views on anybody, but this is what goes for anything that I have to be
+able to maintain, and I'd prefer it for most other things too.  Please
+at least consider the points made here.
+
+First off, I'd suggest printing out a copy of the GNU coding standards,
+and NOT read it.  Burn them, it's a great symbolic gesture.
+
+Anyway, here goes:
+
+
+	 	Chapter 1: Indentation
+
+Tabs are 8 characters, and thus indentations are also 8 characters.
+There are heretic movements that try to make indentations 4 (or even 2!)
+characters deep, and that is akin to trying to define the value of PI to
+be 3.
+
+Rationale: The whole idea behind indentation is to clearly define where
+a block of control starts and ends.  Especially when you've been looking
+at your screen for 20 straight hours, you'll find it a lot easier to see
+how the indentation works if you have large indentations.
+
+Now, some people will claim that having 8-character indentations makes
+the code move too far to the right, and makes it hard to read on a
+80-character terminal screen.  The answer to that is that if you need
+more than 3 levels of indentation, you're screwed anyway, and should fix
+your program.
+
+In short, 8-char indents make things easier to read, and have the added
+benefit of warning you when you're nesting your functions too deep.
+Heed that warning.
+
+The preferred way to ease multiple indentation levels in a switch statement is
+to align the "switch" and its subordinate "case" labels in the same column
+instead of "double-indenting" the "case" labels.  E.g.:
+
+	switch (suffix) {
+	case 'G':
+	case 'g':
+		mem <<= 30;
+		break;
+	case 'M':
+	case 'm':
+		mem <<= 20;
+		break;
+	case 'K':
+	case 'k':
+		mem <<= 10;
+		/* fall through */
+	default:
+		break;
+	}
+
+
+Don't put multiple statements on a single line unless you have
+something to hide:
+
+	if (condition) do_this;
+	  do_something_everytime;
+
+Don't put multiple assignments on a single line either.  Kernel coding style
+is super simple.  Avoid tricky expressions.
+
+Outside of comments, documentation and except in Kconfig, spaces are never
+used for indentation, and the above example is deliberately broken.
+
+Get a decent editor and don't leave whitespace at the end of lines.
+
+
+		Chapter 2: Breaking long lines and strings
+
+Coding style is all about readability and maintainability using commonly
+available tools.
+
+The limit on the length of lines is 80 columns and this is a strongly
+preferred limit.
+
+Statements longer than 80 columns will be broken into sensible chunks.
+Descendants are always substantially shorter than the parent and are placed
+substantially to the right. The same applies to function headers with a long
+argument list. Long strings are as well broken into shorter strings. The
+only exception to this is where exceeding 80 columns significantly increases
+readability and does not hide information.
+
+void fun(int a, int b, int c)
+{
+	if (condition)
+		printk(KERN_WARNING "Warning this is a long printk with "
+						"3 parameters a: %u b: %u "
+						"c: %u \n", a, b, c);
+	else
+		next_statement;
+}
+
+		Chapter 3: Placing Braces and Spaces
+
+The other issue that always comes up in C styling is the placement of
+braces.  Unlike the indent size, there are few technical reasons to
+choose one placement strategy over the other, but the preferred way, as
+shown to us by the prophets Kernighan and Ritchie, is to put the opening
+brace last on the line, and put the closing brace first, thusly:
+
+	if (x is true) {
+		we do y
+	}
+
+This applies to all non-function statement blocks (if, switch, for,
+while, do).  E.g.:
+
+	switch (action) {
+	case KOBJ_ADD:
+		return "add";
+	case KOBJ_REMOVE:
+		return "remove";
+	case KOBJ_CHANGE:
+		return "change";
+	default:
+		return NULL;
+	}
+
+However, there is one special case, namely functions: they have the
+opening brace at the beginning of the next line, thus:
+
+	int function(int x)
+	{
+		body of function
+	}
+
+Heretic people all over the world have claimed that this inconsistency
+is ...  well ...  inconsistent, but all right-thinking people know that
+(a) K&R are _right_ and (b) K&R are right.  Besides, functions are
+special anyway (you can't nest them in C).
+
+Note that the closing brace is empty on a line of its own, _except_ in
+the cases where it is followed by a continuation of the same statement,
+ie a "while" in a do-statement or an "else" in an if-statement, like
+this:
+
+	do {
+		body of do-loop
+	} while (condition);
+
+and
+
+	if (x == y) {
+		..
+	} else if (x > y) {
+		...
+	} else {
+		....
+	}
+
+Rationale: K&R.
+
+Also, note that this brace-placement also minimizes the number of empty
+(or almost empty) lines, without any loss of readability.  Thus, as the
+supply of new-lines on your screen is not a renewable resource (think
+25-line terminal screens here), you have more empty lines to put
+comments on.
+
+Do not unnecessarily use braces where a single statement will do.
+
+if (condition)
+	action();
+
+This does not apply if one branch of a conditional statement is a single
+statement. Use braces in both branches.
+
+if (condition) {
+	do_this();
+	do_that();
+} else {
+	otherwise();
+}
+
+		3.1:  Spaces
+
+Linux kernel style for use of spaces depends (mostly) on
+function-versus-keyword usage.  Use a space after (most) keywords.  The
+notable exceptions are sizeof, typeof, alignof, and __attribute__, which look
+somewhat like functions (and are usually used with parentheses in Linux,
+although they are not required in the language, as in: "sizeof info" after
+"struct fileinfo info;" is declared).
+
+So use a space after these keywords:
+	if, switch, case, for, do, while
+but not with sizeof, typeof, alignof, or __attribute__.  E.g.,
+	s = sizeof(struct file);
+
+Do not add spaces around (inside) parenthesized expressions.  This example is
+*bad*:
+
+	s = sizeof( struct file );
+
+When declaring pointer data or a function that returns a pointer type, the
+preferred use of '*' is adjacent to the data name or function name and not
+adjacent to the type name.  Examples:
+
+	char *linux_banner;
+	unsigned long long memparse(char *ptr, char **retptr);
+	char *match_strdup(substring_t *s);
+
+Use one space around (on each side of) most binary and ternary operators,
+such as any of these:
+
+	=  +  -  <  >  *  /  %  |  &  ^  <=  >=  ==  !=  ?  :
+
+but no space after unary operators:
+	&  *  +  -  ~  !  sizeof  typeof  alignof  __attribute__  defined
+
+no space before the postfix increment & decrement unary operators:
+	++  --
+
+no space after the prefix increment & decrement unary operators:
+	++  --
+
+and no space around the '.' and "->" structure member operators.
+
+Do not leave trailing whitespace at the ends of lines.  Some editors with
+"smart" indentation will insert whitespace at the beginning of new lines as
+appropriate, so you can start typing the next line of code right away.
+However, some such editors do not remove the whitespace if you end up not
+putting a line of code there, such as if you leave a blank line.  As a result,
+you end up with lines containing trailing whitespace.
+
+Git will warn you about patches that introduce trailing whitespace, and can
+optionally strip the trailing whitespace for you; however, if applying a series
+of patches, this may make later patches in the series fail by changing their
+context lines.
+
+
+		Chapter 4: Naming
+
+C is a Spartan language, and so should your naming be.  Unlike Modula-2
+and Pascal programmers, C programmers do not use cute names like
+ThisVariableIsATemporaryCounter.  A C programmer would call that
+variable "tmp", which is much easier to write, and not the least more
+difficult to understand.
+
+HOWEVER, while mixed-case names are frowned upon, descriptive names for
+global variables are a must.  To call a global function "foo" is a
+shooting offense.
+
+GLOBAL variables (to be used only if you _really_ need them) need to
+have descriptive names, as do global functions.  If you have a function
+that counts the number of active users, you should call that
+"count_active_users()" or similar, you should _not_ call it "cntusr()".
+
+Encoding the type of a function into the name (so-called Hungarian
+notation) is brain damaged - the compiler knows the types anyway and can
+check those, and it only confuses the programmer.  No wonder MicroSoft
+makes buggy programs.
+
+LOCAL variable names should be short, and to the point.  If you have
+some random integer loop counter, it should probably be called "i".
+Calling it "loop_counter" is non-productive, if there is no chance of it
+being mis-understood.  Similarly, "tmp" can be just about any type of
+variable that is used to hold a temporary value.
+
+If you are afraid to mix up your local variable names, you have another
+problem, which is called the function-growth-hormone-imbalance syndrome.
+See chapter 6 (Functions).
+
+
+		Chapter 5: Typedefs
+
+Please don't use things like "vps_t".
+
+It's a _mistake_ to use typedef for structures and pointers. When you see a
+
+	vps_t a;
+
+in the source, what does it mean?
+
+In contrast, if it says
+
+	struct virtual_container *a;
+
+you can actually tell what "a" is.
+
+Lots of people think that typedefs "help readability". Not so. They are
+useful only for:
+
+ (a) totally opaque objects (where the typedef is actively used to _hide_
+     what the object is).
+
+     Example: "pte_t" etc. opaque objects that you can only access using
+     the proper accessor functions.
+
+     NOTE! Opaqueness and "accessor functions" are not good in themselves.
+     The reason we have them for things like pte_t etc. is that there
+     really is absolutely _zero_ portably accessible information there.
+
+ (b) Clear integer types, where the abstraction _helps_ avoid confusion
+     whether it is "int" or "long".
+
+     u8/u16/u32 are perfectly fine typedefs, although they fit into
+     category (d) better than here.
+
+     NOTE! Again - there needs to be a _reason_ for this. If something is
+     "unsigned long", then there's no reason to do
+
+	typedef unsigned long myflags_t;
+
+     but if there is a clear reason for why it under certain circumstances
+     might be an "unsigned int" and under other configurations might be
+     "unsigned long", then by all means go ahead and use a typedef.
+
+ (c) when you use sparse to literally create a _new_ type for
+     type-checking.
+
+ (d) New types which are identical to standard C99 types, in certain
+     exceptional circumstances.
+
+     Although it would only take a short amount of time for the eyes and
+     brain to become accustomed to the standard types like 'uint32_t',
+     some people object to their use anyway.
+
+     Therefore, the Linux-specific 'u8/u16/u32/u64' types and their
+     signed equivalents which are identical to standard types are
+     permitted -- although they are not mandatory in new code of your
+     own.
+
+     When editing existing code which already uses one or the other set
+     of types, you should conform to the existing choices in that code.
+
+ (e) Types safe for use in userspace.
+
+     In certain structures which are visible to userspace, we cannot
+     require C99 types and cannot use the 'u32' form above. Thus, we
+     use __u32 and similar types in all structures which are shared
+     with userspace.
+
+Maybe there are other cases too, but the rule should basically be to NEVER
+EVER use a typedef unless you can clearly match one of those rules.
+
+In general, a pointer, or a struct that has elements that can reasonably
+be directly accessed should _never_ be a typedef.
+
+
+		Chapter 6: Functions
+
+Functions should be short and sweet, and do just one thing.  They should
+fit on one or two screenfuls of text (the ISO/ANSI screen size is 80x24,
+as we all know), and do one thing and do that well.
+
+The maximum length of a function is inversely proportional to the
+complexity and indentation level of that function.  So, if you have a
+conceptually simple function that is just one long (but simple)
+case-statement, where you have to do lots of small things for a lot of
+different cases, it's OK to have a longer function.
+
+However, if you have a complex function, and you suspect that a
+less-than-gifted first-year high-school student might not even
+understand what the function is all about, you should adhere to the
+maximum limits all the more closely.  Use helper functions with
+descriptive names (you can ask the compiler to in-line them if you think
+it's performance-critical, and it will probably do a better job of it
+than you would have done).
+
+Another measure of the function is the number of local variables.  They
+shouldn't exceed 5-10, or you're doing something wrong.  Re-think the
+function, and split it into smaller pieces.  A human brain can
+generally easily keep track of about 7 different things, anything more
+and it gets confused.  You know you're brilliant, but maybe you'd like
+to understand what you did 2 weeks from now.
+
+In source files, separate functions with one blank line.  If the function is
+exported, the EXPORT* macro for it should follow immediately after the closing
+function brace line.  E.g.:
+
+int system_is_up(void)
+{
+	return system_state == SYSTEM_RUNNING;
+}
+EXPORT_SYMBOL(system_is_up);
+
+In function prototypes, include parameter names with their data types.
+Although this is not required by the C language, it is preferred in Linux
+because it is a simple way to add valuable information for the reader.
+
+
+		Chapter 7: Centralized exiting of functions
+
+Albeit deprecated by some people, the equivalent of the goto statement is
+used frequently by compilers in form of the unconditional jump instruction.
+
+The goto statement comes in handy when a function exits from multiple
+locations and some common work such as cleanup has to be done.
+
+The rationale is:
+
+- unconditional statements are easier to understand and follow
+- nesting is reduced
+- errors by not updating individual exit points when making
+    modifications are prevented
+- saves the compiler work to optimize redundant code away ;)
+
+int fun(int a)
+{
+	int result = 0;
+	char *buffer = kmalloc(SIZE);
+
+	if (buffer == NULL)
+		return -ENOMEM;
+
+	if (condition1) {
+		while (loop1) {
+			...
+		}
+		result = 1;
+		goto out;
+	}
+	...
+out:
+	kfree(buffer);
+	return result;
+}
+
+		Chapter 8: Commenting
+
+Comments are good, but there is also a danger of over-commenting.  NEVER
+try to explain HOW your code works in a comment: it's much better to
+write the code so that the _working_ is obvious, and it's a waste of
+time to explain badly written code.
+
+Generally, you want your comments to tell WHAT your code does, not HOW.
+Also, try to avoid putting comments inside a function body: if the
+function is so complex that you need to separately comment parts of it,
+you should probably go back to chapter 6 for a while.  You can make
+small comments to note or warn about something particularly clever (or
+ugly), but try to avoid excess.  Instead, put the comments at the head
+of the function, telling people what it does, and possibly WHY it does
+it.
+
+When commenting the kernel API functions, please use the kernel-doc format.
+See the files Documentation/kernel-doc-nano-HOWTO.txt and scripts/kernel-doc
+for details.
+
+Linux style for comments is the C89 "/* ... */" style.
+Don't use C99-style "// ..." comments.
+
+The preferred style for long (multi-line) comments is:
+
+	/*
+	 * This is the preferred style for multi-line
+	 * comments in the Linux kernel source code.
+	 * Please use it consistently.
+	 *
+	 * Description:  A column of asterisks on the left side,
+	 * with beginning and ending almost-blank lines.
+	 */
+
+It's also important to comment data, whether they are basic types or derived
+types.  To this end, use just one data declaration per line (no commas for
+multiple data declarations).  This leaves you room for a small comment on each
+item, explaining its use.
+
+
+		Chapter 9: You've made a mess of it
+
+That's OK, we all do.  You've probably been told by your long-time Unix
+user helper that "GNU emacs" automatically formats the C sources for
+you, and you've noticed that yes, it does do that, but the defaults it
+uses are less than desirable (in fact, they are worse than random
+typing - an infinite number of monkeys typing into GNU emacs would never
+make a good program).
+
+So, you can either get rid of GNU emacs, or change it to use saner
+values.  To do the latter, you can stick the following in your .emacs file:
+
+(defun c-lineup-arglist-tabs-only (ignored)
+  "Line up argument lists by tabs, not spaces"
+  (let* ((anchor (c-langelem-pos c-syntactic-element))
+	 (column (c-langelem-2nd-pos c-syntactic-element))
+	 (offset (- (1+ column) anchor))
+	 (steps (floor offset c-basic-offset)))
+    (* (max steps 1)
+       c-basic-offset)))
+
+(add-hook 'c-mode-common-hook
+          (lambda ()
+            ;; Add kernel style
+            (c-add-style
+             "linux-tabs-only"
+             '("linux" (c-offsets-alist
+                        (arglist-cont-nonempty
+                         c-lineup-gcc-asm-reg
+                         c-lineup-arglist-tabs-only))))))
+
+(add-hook 'c-mode-hook
+          (lambda ()
+            (let ((filename (buffer-file-name)))
+              ;; Enable kernel mode for the appropriate files
+              (when (and filename
+                         (string-match (expand-file-name "~/src/linux-trees")
+                                       filename))
+                (setq indent-tabs-mode t)
+                (c-set-style "linux-tabs-only")))))
+
+This will make emacs go better with the kernel coding style for C
+files below ~/src/linux-trees.
+
+But even if you fail in getting emacs to do sane formatting, not
+everything is lost: use "indent".
+
+Now, again, GNU indent has the same brain-dead settings that GNU emacs
+has, which is why you need to give it a few command line options.
+However, that's not too bad, because even the makers of GNU indent
+recognize the authority of K&R (the GNU people aren't evil, they are
+just severely misguided in this matter), so you just give indent the
+options "-kr -i8" (stands for "K&R, 8 character indents"), or use
+"scripts/Lindent", which indents in the latest style.
+
+"indent" has a lot of options, and especially when it comes to comment
+re-formatting you may want to take a look at the man page.  But
+remember: "indent" is not a fix for bad programming.
+
+
+		Chapter 10: Kconfig configuration files
+
+For all of the Kconfig* configuration files throughout the source tree,
+the indentation is somewhat different.  Lines under a "config" definition
+are indented with one tab, while help text is indented an additional two
+spaces.  Example:
+
+config AUDIT
+	bool "Auditing support"
+	depends on NET
+	help
+	  Enable auditing infrastructure that can be used with another
+	  kernel subsystem, such as SELinux (which requires this for
+	  logging of avc messages output).  Does not do system-call
+	  auditing without CONFIG_AUDITSYSCALL.
+
+Features that might still be considered unstable should be defined as
+dependent on "EXPERIMENTAL":
+
+config SLUB
+	depends on EXPERIMENTAL && !ARCH_USES_SLAB_PAGE_STRUCT
+	bool "SLUB (Unqueued Allocator)"
+	...
+
+while seriously dangerous features (such as write support for certain
+filesystems) should advertise this prominently in their prompt string:
+
+config ADFS_FS_RW
+	bool "ADFS write support (DANGEROUS)"
+	depends on ADFS_FS
+	...
+
+For full documentation on the configuration files, see the file
+Documentation/kbuild/kconfig-language.txt.
+
+
+		Chapter 11: Data structures
+
+Data structures that have visibility outside the single-threaded
+environment they are created and destroyed in should always have
+reference counts.  In the kernel, garbage collection doesn't exist (and
+outside the kernel garbage collection is slow and inefficient), which
+means that you absolutely _have_ to reference count all your uses.
+
+Reference counting means that you can avoid locking, and allows multiple
+users to have access to the data structure in parallel - and not having
+to worry about the structure suddenly going away from under them just
+because they slept or did something else for a while.
+
+Note that locking is _not_ a replacement for reference counting.
+Locking is used to keep data structures coherent, while reference
+counting is a memory management technique.  Usually both are needed, and
+they are not to be confused with each other.
+
+Many data structures can indeed have two levels of reference counting,
+when there are users of different "classes".  The subclass count counts
+the number of subclass users, and decrements the global count just once
+when the subclass count goes to zero.
+
+Examples of this kind of "multi-level-reference-counting" can be found in
+memory management ("struct mm_struct": mm_users and mm_count), and in
+filesystem code ("struct super_block": s_count and s_active).
+
+Remember: if another thread can find your data structure, and you don't
+have a reference count on it, you almost certainly have a bug.
+
+
+		Chapter 12: Macros, Enums and RTL
+
+Names of macros defining constants and labels in enums are capitalized.
+
+#define CONSTANT 0x12345
+
+Enums are preferred when defining several related constants.
+
+CAPITALIZED macro names are appreciated but macros resembling functions
+may be named in lower case.
+
+Generally, inline functions are preferable to macros resembling functions.
+
+Macros with multiple statements should be enclosed in a do - while block:
+
+#define macrofun(a, b, c) 			\
+	do {					\
+		if (a == 5)			\
+			do_this(b, c);		\
+	} while (0)
+
+Things to avoid when using macros:
+
+1) macros that affect control flow:
+
+#define FOO(x)					\
+	do {					\
+		if (blah(x) < 0)		\
+			return -EBUGGERED;	\
+	} while(0)
+
+is a _very_ bad idea.  It looks like a function call but exits the "calling"
+function; don't break the internal parsers of those who will read the code.
+
+2) macros that depend on having a local variable with a magic name:
+
+#define FOO(val) bar(index, val)
+
+might look like a good thing, but it's confusing as hell when one reads the
+code and it's prone to breakage from seemingly innocent changes.
+
+3) macros with arguments that are used as l-values: FOO(x) = y; will
+bite you if somebody e.g. turns FOO into an inline function.
+
+4) forgetting about precedence: macros defining constants using expressions
+must enclose the expression in parentheses. Beware of similar issues with
+macros using parameters.
+
+#define CONSTANT 0x4000
+#define CONSTEXP (CONSTANT | 3)
+
+The cpp manual deals with macros exhaustively. The gcc internals manual also
+covers RTL which is used frequently with assembly language in the kernel.
+
+
+		Chapter 13: Printing kernel messages
+
+Kernel developers like to be seen as literate. Do mind the spelling
+of kernel messages to make a good impression. Do not use crippled
+words like "dont"; use "do not" or "don't" instead.  Make the messages
+concise, clear, and unambiguous.
+
+Kernel messages do not have to be terminated with a period.
+
+Printing numbers in parentheses (%d) adds no value and should be avoided.
+
+There are a number of driver model diagnostic macros in <linux/device.h>
+which you should use to make sure messages are matched to the right device
+and driver, and are tagged with the right level:  dev_err(), dev_warn(),
+dev_info(), and so forth.  For messages that aren't associated with a
+particular device, <linux/kernel.h> defines pr_debug() and pr_info().
+
+Coming up with good debugging messages can be quite a challenge; and once
+you have them, they can be a huge help for remote troubleshooting.  Such
+messages should be compiled out when the DEBUG symbol is not defined (that
+is, by default they are not included).  When you use dev_dbg() or pr_debug(),
+that's automatic.  Many subsystems have Kconfig options to turn on -DDEBUG.
+A related convention uses VERBOSE_DEBUG to add dev_vdbg() messages to the
+ones already enabled by DEBUG.
+
+
+		Chapter 14: Allocating memory
+
+The kernel provides the following general purpose memory allocators:
+kmalloc(), kzalloc(), kcalloc(), and vmalloc().  Please refer to the API
+documentation for further information about them.
+
+The preferred form for passing a size of a struct is the following:
+
+	p = kmalloc(sizeof(*p), ...);
+
+The alternative form where struct name is spelled out hurts readability and
+introduces an opportunity for a bug when the pointer variable type is changed
+but the corresponding sizeof that is passed to a memory allocator is not.
+
+Casting the return value which is a void pointer is redundant. The conversion
+from void pointer to any other pointer type is guaranteed by the C programming
+language.
+
+
+		Chapter 15: The inline disease
+
+There appears to be a common misperception that gcc has a magic "make me
+faster" speedup option called "inline". While the use of inlines can be
+appropriate (for example as a means of replacing macros, see Chapter 12), it
+very often is not. Abundant use of the inline keyword leads to a much bigger
+kernel, which in turn slows the system as a whole down, due to a bigger
+icache footprint for the CPU and simply because there is less memory
+available for the pagecache. Just think about it; a pagecache miss causes a
+disk seek, which easily takes 5 miliseconds. There are a LOT of cpu cycles
+that can go into these 5 miliseconds.
+
+A reasonable rule of thumb is to not put inline at functions that have more
+than 3 lines of code in them. An exception to this rule are the cases where
+a parameter is known to be a compiletime constant, and as a result of this
+constantness you *know* the compiler will be able to optimize most of your
+function away at compile time. For a good example of this later case, see
+the kmalloc() inline function.
+
+Often people argue that adding inline to functions that are static and used
+only once is always a win since there is no space tradeoff. While this is
+technically correct, gcc is capable of inlining these automatically without
+help, and the maintenance issue of removing the inline when a second user
+appears outweighs the potential value of the hint that tells gcc to do
+something it would have done anyway.
+
+
+		Chapter 16: Function return values and names
+
+Functions can return values of many different kinds, and one of the
+most common is a value indicating whether the function succeeded or
+failed.  Such a value can be represented as an error-code integer
+(-Exxx = failure, 0 = success) or a "succeeded" boolean (0 = failure,
+non-zero = success).
+
+Mixing up these two sorts of representations is a fertile source of
+difficult-to-find bugs.  If the C language included a strong distinction
+between integers and booleans then the compiler would find these mistakes
+for us... but it doesn't.  To help prevent such bugs, always follow this
+convention:
+
+	If the name of a function is an action or an imperative command,
+	the function should return an error-code integer.  If the name
+	is a predicate, the function should return a "succeeded" boolean.
+
+For example, "add work" is a command, and the add_work() function returns 0
+for success or -EBUSY for failure.  In the same way, "PCI device present" is
+a predicate, and the pci_dev_present() function returns 1 if it succeeds in
+finding a matching device or 0 if it doesn't.
+
+All EXPORTed functions must respect this convention, and so should all
+public functions.  Private (static) functions need not, but it is
+recommended that they do.
+
+Functions whose return value is the actual result of a computation, rather
+than an indication of whether the computation succeeded, are not subject to
+this rule.  Generally they indicate failure by returning some out-of-range
+result.  Typical examples would be functions that return pointers; they use
+NULL or the ERR_PTR mechanism to report failure.
+
+
+		Chapter 17:  Don't re-invent the kernel macros
+
+The header file include/linux/kernel.h contains a number of macros that
+you should use, rather than explicitly coding some variant of them yourself.
+For example, if you need to calculate the length of an array, take advantage
+of the macro
+
+  #define ARRAY_SIZE(x) (sizeof(x) / sizeof((x)[0]))
+
+Similarly, if you need to calculate the size of some structure member, use
+
+  #define FIELD_SIZEOF(t, f) (sizeof(((t*)0)->f))
+
+There are also min() and max() macros that do strict type checking if you
+need them.  Feel free to peruse that header file to see what else is already
+defined that you shouldn't reproduce in your code.
+
+
+		Chapter 18:  Editor modelines and other cruft
+
+Some editors can interpret configuration information embedded in source files,
+indicated with special markers.  For example, emacs interprets lines marked
+like this:
+
+-*- mode: c -*-
+
+Or like this:
+
+/*
+Local Variables:
+compile-command: "gcc -DMAGIC_DEBUG_FLAG foo.c"
+End:
+*/
+
+Vim interprets markers that look like this:
+
+/* vim:set sw=8 noet */
+
+Do not include any of these in source files.  People have their own personal
+editor configurations, and your source files should not override them.  This
+includes markers for indentation and mode configuration.  People may use their
+own custom mode, or may have some other magic method for making indentation
+work correctly.

+
+
+
+	How to Get Your Change Into the Linux Kernel
+		or
+	Care And Operation Of Your Linus Torvalds
+
+
+
+For a person or company who wishes to submit a change to the Linux
+kernel, the process can sometimes be daunting if you're not familiar
+with "the system."  This text is a collection of suggestions which
+can greatly increase the chances of your change being accepted.
+
+Read Documentation/SubmitChecklist for a list of items to check
+before submitting code.  If you are submitting a driver, also read
+Documentation/SubmittingDrivers.
+
+
+
+--------------------------------------------
+SECTION 1 - CREATING AND SENDING YOUR CHANGE
+--------------------------------------------
+
+
+
+1) "diff -up"
+------------
+
+Use "diff -up" or "diff -uprN" to create patches.
+
+All changes to the Linux kernel occur in the form of patches, as
+generated by diff(1).  When creating your patch, make sure to create it
+in "unified diff" format, as supplied by the '-u' argument to diff(1).
+Also, please use the '-p' argument which shows which C function each
+change is in - that makes the resultant diff a lot easier to read.
+Patches should be based in the root kernel source directory,
+not in any lower subdirectory.
+
+To create a patch for a single file, it is often sufficient to do:
+
+	SRCTREE= linux-2.6
+	MYFILE=  drivers/net/mydriver.c
+
+	cd $SRCTREE
+	cp $MYFILE $MYFILE.orig
+	vi $MYFILE	# make your change
+	cd ..
+	diff -up $SRCTREE/$MYFILE{.orig,} > /tmp/patch
+
+To create a patch for multiple files, you should unpack a "vanilla",
+or unmodified kernel source tree, and generate a diff against your
+own source tree.  For example:
+
+	MYSRC= /devel/linux-2.6
+
+	tar xvfz linux-2.6.12.tar.gz
+	mv linux-2.6.12 linux-2.6.12-vanilla
+	diff -uprN -X linux-2.6.12-vanilla/Documentation/dontdiff \
+		linux-2.6.12-vanilla $MYSRC > /tmp/patch
+
+"dontdiff" is a list of files which are generated by the kernel during
+the build process, and should be ignored in any diff(1)-generated
+patch.  The "dontdiff" file is included in the kernel tree in
+2.6.12 and later.  For earlier kernel versions, you can get it
+from <http://www.xenotime.net/linux/doc/dontdiff>.
+
+Make sure your patch does not include any extra files which do not
+belong in a patch submission.  Make sure to review your patch -after-
+generated it with diff(1), to ensure accuracy.
+
+If your changes produce a lot of deltas, you may want to look into
+splitting them into individual patches which modify things in
+logical stages.  This will facilitate easier reviewing by other
+kernel developers, very important if you want your patch accepted.
+There are a number of scripts which can aid in this:
+
+Quilt:
+http://savannah.nongnu.org/projects/quilt
+
+Andrew Morton's patch scripts:
+http://www.zip.com.au/~akpm/linux/patches/
+Instead of these scripts, quilt is the recommended patch management
+tool (see above).
+
+
+
+2) Describe your changes.
+
+Describe the technical detail of the change(s) your patch includes.
+
+Be as specific as possible.  The WORST descriptions possible include
+things like "update driver X", "bug fix for driver X", or "this patch
+includes updates for subsystem X.  Please apply."
+
+If your description starts to get long, that's a sign that you probably
+need to split up your patch.  See #3, next.
+
+
+
+3) Separate your changes.
+
+Separate _logical changes_ into a single patch file.
+
+For example, if your changes include both bug fixes and performance
+enhancements for a single driver, separate those changes into two
+or more patches.  If your changes include an API update, and a new
+driver which uses that new API, separate those into two patches.
+
+On the other hand, if you make a single change to numerous files,
+group those changes into a single patch.  Thus a single logical change
+is contained within a single patch.
+
+If one patch depends on another patch in order for a change to be
+complete, that is OK.  Simply note "this patch depends on patch X"
+in your patch description.
+
+If you cannot condense your patch set into a smaller set of patches,
+then only post say 15 or so at a time and wait for review and integration.
+
+
+
+4) Style check your changes.
+
+Check your patch for basic style violations, details of which can be
+found in Documentation/CodingStyle.  Failure to do so simply wastes
+the reviewers time and will get your patch rejected, probably
+without even being read.
+
+At a minimum you should check your patches with the patch style
+checker prior to submission (scripts/checkpatch.pl).  You should
+be able to justify all violations that remain in your patch.
+
+
+
+5) Select e-mail destination.
+
+Look through the MAINTAINERS file and the source code, and determine
+if your change applies to a specific subsystem of the kernel, with
+an assigned maintainer.  If so, e-mail that person.
+
+If no maintainer is listed, or the maintainer does not respond, send
+your patch to the primary Linux kernel developer's mailing list,
+linux-kernel@vger.kernel.org.  Most kernel developers monitor this
+e-mail list, and can comment on your changes.
+
+
+Do not send more than 15 patches at once to the vger mailing lists!!!
+
+
+Linus Torvalds is the final arbiter of all changes accepted into the
+Linux kernel.  His e-mail address is <torvalds@linux-foundation.org>.
+He gets a lot of e-mail, so typically you should do your best to -avoid-
+sending him e-mail.
+
+Patches which are bug fixes, are "obvious" changes, or similarly
+require little discussion should be sent or CC'd to Linus.  Patches
+which require discussion or do not have a clear advantage should
+usually be sent first to linux-kernel.  Only after the patch is
+discussed should the patch then be submitted to Linus.
+
+
+
+6) Select your CC (e-mail carbon copy) list.
+
+Unless you have a reason NOT to do so, CC linux-kernel@vger.kernel.org.
+
+Other kernel developers besides Linus need to be aware of your change,
+so that they may comment on it and offer code review and suggestions.
+linux-kernel is the primary Linux kernel developer mailing list.
+Other mailing lists are available for specific subsystems, such as
+USB, framebuffer devices, the VFS, the SCSI subsystem, etc.  See the
+MAINTAINERS file for a mailing list that relates specifically to
+your change.
+
+Majordomo lists of VGER.KERNEL.ORG at:
+	<http://vger.kernel.org/vger-lists.html>
+
+If changes affect userland-kernel interfaces, please send
+the MAN-PAGES maintainer (as listed in the MAINTAINERS file)
+a man-pages patch, or at least a notification of the change,
+so that some information makes its way into the manual pages.
+
+Even if the maintainer did not respond in step #4, make sure to ALWAYS
+copy the maintainer when you change their code.
+
+For small patches you may want to CC the Trivial Patch Monkey
+trivial@kernel.org managed by Adrian Bunk; which collects "trivial"
+patches. Trivial patches must qualify for one of the following rules:
+ Spelling fixes in documentation
+ Spelling fixes which could break grep(1)
+ Warning fixes (cluttering with useless warnings is bad)
+ Compilation fixes (only if they are actually correct)
+ Runtime fixes (only if they actually fix things)
+ Removing use of deprecated functions/macros (eg. check_region)
+ Contact detail and documentation fixes
+ Non-portable code replaced by portable code (even in arch-specific,
+ since people copy, as long as it's trivial)
+ Any fix by the author/maintainer of the file (ie. patch monkey
+ in re-transmission mode)
+URL: <http://www.kernel.org/pub/linux/kernel/people/bunk/trivial/>
+
+
+
+7) No MIME, no links, no compression, no attachments.  Just plain text.
+
+Linus and other kernel developers need to be able to read and comment
+on the changes you are submitting.  It is important for a kernel
+developer to be able to "quote" your changes, using standard e-mail
+tools, so that they may comment on specific portions of your code.
+
+For this reason, all patches should be submitting e-mail "inline".
+WARNING:  Be wary of your editor's word-wrap corrupting your patch,
+if you choose to cut-n-paste your patch.
+
+Do not attach the patch as a MIME attachment, compressed or not.
+Many popular e-mail applications will not always transmit a MIME
+attachment as plain text, making it impossible to comment on your
+code.  A MIME attachment also takes Linus a bit more time to process,
+decreasing the likelihood of your MIME-attached change being accepted.
+
+Exception:  If your mailer is mangling patches then someone may ask
+you to re-send them using MIME.
+
+See Documentation/email-clients.txt for hints about configuring
+your e-mail client so that it sends your patches untouched.
+
+8) E-mail size.
+
+When sending patches to Linus, always follow step #7.
+
+Large changes are not appropriate for mailing lists, and some
+maintainers.  If your patch, uncompressed, exceeds 40 kB in size,
+it is preferred that you store your patch on an Internet-accessible
+server, and provide instead a URL (link) pointing to your patch.
+
+
+
+9) Name your kernel version.
+
+It is important to note, either in the subject line or in the patch
+description, the kernel version to which this patch applies.
+
+If the patch does not apply cleanly to the latest kernel version,
+Linus will not apply it.
+
+
+
+10) Don't get discouraged.  Re-submit.
+
+After you have submitted your change, be patient and wait.  If Linus
+likes your change and applies it, it will appear in the next version
+of the kernel that he releases.
+
+However, if your change doesn't appear in the next version of the
+kernel, there could be any number of reasons.  It's YOUR job to
+narrow down those reasons, correct what was wrong, and submit your
+updated change.
+
+It is quite common for Linus to "drop" your patch without comment.
+That's the nature of the system.  If he drops your patch, it could be
+due to
+* Your patch did not apply cleanly to the latest kernel version.
+* Your patch was not sufficiently discussed on linux-kernel.
+* A style issue (see section 2).
+* An e-mail formatting issue (re-read this section).
+* A technical problem with your change.
+* He gets tons of e-mail, and yours got lost in the shuffle.
+* You are being annoying.
+
+When in doubt, solicit comments on linux-kernel mailing list.
+
+
+
+11) Include PATCH in the subject
+
+Due to high e-mail traffic to Linus, and to linux-kernel, it is common
+convention to prefix your subject line with [PATCH].  This lets Linus
+and other kernel developers more easily distinguish patches from other
+e-mail discussions.
+
+
+
+12) Sign your work
+
+To improve tracking of who did what, especially with patches that can
+percolate to their final resting place in the kernel through several
+layers of maintainers, we've introduced a "sign-off" procedure on
+patches that are being emailed around.
+
+The sign-off is a simple line at the end of the explanation for the
+patch, which certifies that you wrote it or otherwise have the right to
+pass it on as a open-source patch.  The rules are pretty simple: if you
+can certify the below:
+
+        Developer's Certificate of Origin 1.1
+
+        By making a contribution to this project, I certify that:
+
+        (a) The contribution was created in whole or in part by me and I
+            have the right to submit it under the open source license
+            indicated in the file; or
+
+        (b) The contribution is based upon previous work that, to the best
+            of my knowledge, is covered under an appropriate open source
+            license and I have the right under that license to submit that
+            work with modifications, whether created in whole or in part
+            by me, under the same open source license (unless I am
+            permitted to submit under a different license), as indicated
+            in the file; or
+
+        (c) The contribution was provided directly to me by some other
+            person who certified (a), (b) or (c) and I have not modified
+            it.
+
+	(d) I understand and agree that this project and the contribution
+	    are public and that a record of the contribution (including all
+	    personal information I submit with it, including my sign-off) is
+	    maintained indefinitely and may be redistributed consistent with
+	    this project or the open source license(s) involved.
+
+then you just add a line saying
+
+	Signed-off-by: Random J Developer <random@developer.example.org>
+
+using your real name (sorry, no pseudonyms or anonymous contributions.)
+
+Some people also put extra tags at the end.  They'll just be ignored for
+now, but you can do this to mark internal company procedures or just
+point out some special detail about the sign-off.
+
+
+13) When to use Acked-by:
+
+The Signed-off-by: tag indicates that the signer was involved in the
+development of the patch, or that he/she was in the patch's delivery path.
+
+If a person was not directly involved in the preparation or handling of a
+patch but wishes to signify and record their approval of it then they can
+arrange to have an Acked-by: line added to the patch's changelog.
+
+Acked-by: is often used by the maintainer of the affected code when that
+maintainer neither contributed to nor forwarded the patch.
+
+Acked-by: is not as formal as Signed-off-by:.  It is a record that the acker
+has at least reviewed the patch and has indicated acceptance.  Hence patch
+mergers will sometimes manually convert an acker's "yep, looks good to me"
+into an Acked-by:.
+
+Acked-by: does not necessarily indicate acknowledgement of the entire patch.
+For example, if a patch affects multiple subsystems and has an Acked-by: from
+one subsystem maintainer then this usually indicates acknowledgement of just
+the part which affects that maintainer's code.  Judgement should be used here.
+ When in doubt people should refer to the original discussion in the mailing
+list archives.
+
+
+14) The canonical patch format
+
+The canonical patch subject line is:
+
+    Subject: [PATCH 001/123] subsystem: summary phrase
+
+The canonical patch message body contains the following:
+
+  - A "from" line specifying the patch author.
+
+  - An empty line.
+
+  - The body of the explanation, which will be copied to the
+    permanent changelog to describe this patch.
+
+  - The "Signed-off-by:" lines, described above, which will
+    also go in the changelog.
+
+  - A marker line containing simply "---".
+
+  - Any additional comments not suitable for the changelog.
+
+  - The actual patch (diff output).
+
+The Subject line format makes it very easy to sort the emails
+alphabetically by subject line - pretty much any email reader will
+support that - since because the sequence number is zero-padded,
+the numerical and alphabetic sort is the same.
+
+The "subsystem" in the email's Subject should identify which
+area or subsystem of the kernel is being patched.
+
+The "summary phrase" in the email's Subject should concisely
+describe the patch which that email contains.  The "summary
+phrase" should not be a filename.  Do not use the same "summary
+phrase" for every patch in a whole patch series (where a "patch
+series" is an ordered sequence of multiple, related patches).
+
+Bear in mind that the "summary phrase" of your email becomes
+a globally-unique identifier for that patch.  It propagates
+all the way into the git changelog.  The "summary phrase" may
+later be used in developer discussions which refer to the patch.
+People will want to google for the "summary phrase" to read
+discussion regarding that patch.
+
+A couple of example Subjects:
+
+    Subject: [patch 2/5] ext2: improve scalability of bitmap searching
+    Subject: [PATCHv2 001/207] x86: fix eflags tracking
+
+The "from" line must be the very first line in the message body,
+and has the form:
+
+        From: Original Author <author@example.com>
+
+The "from" line specifies who will be credited as the author of the
+patch in the permanent changelog.  If the "from" line is missing,
+then the "From:" line from the email header will be used to determine
+the patch author in the changelog.
+
+The explanation body will be committed to the permanent source
+changelog, so should make sense to a competent reader who has long
+since forgotten the immediate details of the discussion that might
+have led to this patch.
+
+The "---" marker line serves the essential purpose of marking for patch
+handling tools where the changelog message ends.
+
+One good use for the additional comments after the "---" marker is for
+a diffstat, to show what files have changed, and the number of inserted
+and deleted lines per file.  A diffstat is especially useful on bigger
+patches.  Other comments relevant only to the moment or the maintainer,
+not suitable for the permanent changelog, should also go here.
+Use diffstat options "-p 1 -w 70" so that filenames are listed from the
+top of the kernel source tree and don't use too much horizontal space
+(easily fit in 80 columns, maybe with some indentation).
+
+See more details on the proper patch format in the following
+references.
+
+
+
+
+-----------------------------------
+SECTION 2 - HINTS, TIPS, AND TRICKS
+-----------------------------------
+
+This section lists many of the common "rules" associated with code
+submitted to the kernel.  There are always exceptions... but you must
+have a really good reason for doing so.  You could probably call this
+section Linus Computer Science 101.
+
+
+
+1) Read Documentation/CodingStyle
+
+Nuff said.  If your code deviates too much from this, it is likely
+to be rejected without further review, and without comment.
+
+One significant exception is when moving code from one file to
+another -- in this case you should not modify the moved code at all in
+the same patch which moves it.  This clearly delineates the act of
+moving the code and your changes.  This greatly aids review of the
+actual differences and allows tools to better track the history of
+the code itself.
+
+Check your patches with the patch style checker prior to submission
+(scripts/checkpatch.pl).  The style checker should be viewed as
+a guide not as the final word.  If your code looks better with
+a violation then its probably best left alone.
+
+The checker reports at three levels:
+ - ERROR: things that are very likely to be wrong
+ - WARNING: things requiring careful review
+ - CHECK: things requiring thought
+
+You should be able to justify all violations that remain in your
+patch.
+
+
+
+2) #ifdefs are ugly
+
+Code cluttered with ifdefs is difficult to read and maintain.  Don't do
+it.  Instead, put your ifdefs in a header, and conditionally define
+'static inline' functions, or macros, which are used in the code.
+Let the compiler optimize away the "no-op" case.
+
+Simple example, of poor code:
+
+	dev = alloc_etherdev (sizeof(struct funky_private));
+	if (!dev)
+		return -ENODEV;
+	#ifdef CONFIG_NET_FUNKINESS
+	init_funky_net(dev);
+	#endif
+
+Cleaned-up example:
+
+(in header)
+	#ifndef CONFIG_NET_FUNKINESS
+	static inline void init_funky_net (struct net_device *d) {}
+	#endif
+
+(in the code itself)
+	dev = alloc_etherdev (sizeof(struct funky_private));
+	if (!dev)
+		return -ENODEV;
+	init_funky_net(dev);
+
+
+
+3) 'static inline' is better than a macro
+
+Static inline functions are greatly preferred over macros.
+They provide type safety, have no length limitations, no formatting
+limitations, and under gcc they are as cheap as macros.
+
+Macros should only be used for cases where a static inline is clearly
+suboptimal [there a few, isolated cases of this in fast paths],
+or where it is impossible to use a static inline function [such as
+string-izing].
+
+'static inline' is preferred over 'static __inline__', 'extern inline',
+and 'extern __inline__'.
+
+
+
+4) Don't over-design.
+
+Don't try to anticipate nebulous future cases which may or may not
+be useful:  "Make it as simple as you can, and no simpler."
+

+		       COMBOOT and COM32 files
+
+
+Syslinux supports simple standalone programs, using a file format
+similar to DOS ".com" files.  A 32-bit version, called COM32, is also
+provided.  A simple API provides access to a limited set of filesystem
+and console functions.
+
+
+	++++ COMBOOT file format ++++
+
+A COMBOOT file is a raw binary file containing 16-bit code.  It should
+be linked to run at offset 0x100, and contain no absolute segment
+references.  It is run in 16-bit real mode.
+
+A COMBOOT image can be written to be compatible with MS-DOS.  Such a
+file will usually have extension ".com".  A COMBOOT file which is not
+compatible with MS-DOS will usually have extension ".cbt".
+
+Before running the program, Syslinux sets up the following fields in
+the Program Segment Prefix (PSP), a structure at offset 0 in the
+program segment:
+
+ Offset	Size	Meaning
+ 0	word	Contains an INT 20h instruction
+ 2	word	Contains the paragraph (16-byte "segment" address) at
+		the end of memory available to the program.
+ 128	byte	Length of the command line arguments, including the leading
+		space but not including the final CR character.
+ 129	127b	Command line arguments, starting with a space and ending
+		with a CR character (ASCII 13).
+
+The program is allowed to use memory between the PSP paragraph (which
+all the CS, DS, ES and SS registers point to at program start) and the
+paragraph value given at offset 2.
+
+On startup, SP is set up to point to the end of the 64K segment, at
+0xfffe.  Under DOS it is possible for SP to contain a smaller
+value if memory is very tight; this is never the case under Syslinux.
+
+The program should make no assumptions about what segment address it
+will be loaded at; instead it should look at the segment registers on
+program startup.  Both DOS and Syslinux will guarantee CS == DS == ES
+== SS on program start; the program should not assume anything about
+the values of FS or GS.
+
+To exit, a program can either execute a near RET (which will jump to
+offset 0 which contains an INT 20h instruction, terminating the
+program), or execute INT 20h or INT 21h AH=00h or INT 21h AH=4Ch.
+If compatiblity with Syslinux 1.xx is desired, use INT 20h.
+
+
+	++++ COM32R file format ++++
+
+A COM32R file is a raw binary file containing 32-bit code.  It should
+be self-relocating, as it will be loaded by the Syslinux core at any
+4K aligned address.  It will be run in flat-memory 32-bit protected
+mode.  Under Syslinux, it will be run in CPL 0, however, since it may
+be possible to create a COM32 execution engine that would run under
+something like Linux DOSEMU, it is recommended that the code does not
+assume CPL 0 unless absolutely necessary.
+
+A COM32R program must start with the byte sequence B8 FE 4C CD 21 (mov
+eax,21cd4cfeh) as a magic number.
+
+The COM32R format replaces the earlier COM32 format, which was linked
+to a fixed address (0x101000).
+
+A COM32R file should have extension ".c32".
+
+On startup, CS will be set up as a flat 32-bit code segment, and DS ==
+ES == SS will be set up as the equivalent flat 32-bit data segment.
+FS and GS are reserved for future use and are currently initialized to
+zero.  A COM32R image should not assume any particular values of
+segment selectors.
+
+ESP is set up at the end of available memory and also serves as
+notification to the program how much memory is available.
+
+The following arguments are passed to the program on the stack:
+
+ Address  Size	Meaning
+ [ESP]    dword Return (termination) address
+ [ESP+4]  dword	Number of additional arguments (currently 8)
+ [ESP+8]  dword	Pointer to the command line arguments (null-terminated string)
+ [ESP+12] dword Pointer to INT call helper function
+ [ESP+16] dword Pointer to low memory bounce buffer
+ [ESP+20] dword Size of low memory bounce buffer
+ [ESP+24] dword Pointer to FAR call helper function (new in 2.05)
+ [ESP+28] dword Pointer to CDECL helper function (new in 3.54)
+ [ESP+32] dword Amount of memory controlled by the Syslinux core (new in 3.74)
+ [ESP+36] dword Pointer to the filename of the com32 module (new in 3.86)
+ [ESP+40] dword	Pointer to protected-mode functions (new in 4.00)
+
+The libcom32 startup code loads this into a structure named __com32,
+defined in <com32.h>:
+
+extern struct com32_sys_args {
+    uint32_t cs_sysargs;
+    char *cs_cmdline;
+    void __cdecl(*cs_intcall)(uint8_t, const com32sys_t *, com32sys_t *);
+    void *cs_bounce;
+    uint32_t cs_bounce_size;
+    void __cdecl(*cs_farcall)(uint32_t, const com32sys_t *, com32sys_t *);
+    int __cdecl(*cs_cfarcall)(uint32_t, const void *, uint32_t);
+    uint32_t cs_memsize;
+    const char *cs_name;
+    const struct com32_pmapi *cs_pm;
+} __com32;
+
+The intcall helper function can be used to issue BIOS or Syslinux API
+calls, and takes the interrupt number as first argument.  The second
+argument is a pointer to the input register definition, an instance of
+the following structure (available in <com32.h>):
+
+typedef union {
+  uint32_t l;
+  uint16_t w[2];
+  uint8_t  b[4];
+} reg32_t;
+
+typedef struct {
+  uint16_t gs;			/* Offset  0 */
+  uint16_t fs;			/* Offset  2 */
+  uint16_t es;			/* Offset  4 */
+  uint16_t ds;			/* Offset  6 */
+
+  reg32_t edi;			/* Offset  8 */
+  reg32_t esi;			/* Offset 12 */
+  reg32_t ebp;			/* Offset 16 */
+  reg32_t _unused_esp;		/* Offset 20 */
+  reg32_t ebx;			/* Offset 24 */
+  reg32_t edx;			/* Offset 28 */
+  reg32_t ecx;			/* Offset 32 */
+  reg32_t eax;			/* Offset 36 */
+
+  reg32_t eflags;		/* Offset 40 */
+} com32sys_t;
+
+The third argument is a pointer to the output register definition, an
+instance of the same structure.  The third argument can also be zero
+(NULL).
+
+Since BIOS or Syslinux API calls can generally only manipulate data
+below address 0x100000, a "bounce buffer" in low memory, at least 64K
+in size, is available, to copy data in and out.
+
+The farcall helper function behaves similarly, but takes as its first
+argument the CS:IP (in the form (CS << 16) + IP) of procedure to be
+invoked via a FAR CALL.
+
+The cfarcall helper function takes (CS << 16)+IP, a pointer to a stack
+frame, a size of that stack frame, and returns the return value of EAX
+(which may need to be appropriate truncated by the user.)
+
+Starting in version 4.00, some of these API calls are available as
+protected-mode function calls, using the regparm(3) calling convention
+(the first three argumetns in EAX, EDX, ECX; the rest on the stack.)
+Those functions are defined in struct com32_pmapi, defined in
+<syslinux/pmapi.h>.
+
+
+	++++ SYSLINUX API CALLS +++
+
+Syslinux provides the following API calls.  Syslinux 1.xx only
+supported INT 20h - terminate program. [] indicates the first version
+of Syslinux which supported this feature (correctly.)
+
+NOTE: Most of the API functionality is still experimental.  Expect to
+find bugs.
+
+
+	++++ DOS-COMPATIBLE API CALLS ++++
+
+INT 20h		[1.48] Terminate program
+INT 21h AH=00h	[2.00] Terminate program
+INT 21h AH=4Ch	[2.00] Terminate program
+
+	All of these terminate the program.
+
+
+INT 21h AH=01h	[2.01] Get Key with Echo
+
+	Reads a key from the console input, with echo to the console
+	output.  The read character is returned in AL.  Extended
+	characters received from the keyboard are returned as NUL (00h)
+	+ the extended character code.
+
+
+INT 21h AH=02h	[2.01] Write Character
+
+	Writes a character in DL to the console (video and serial)
+	output.
+
+
+INT 21h AH=04h	[2.01] Write Character to Serial Port
+
+	Writes a character in DL to the serial console output
+	(if enabled.)  If no serial port is configured, this routine
+	does nothing.
+
+
+INT 21h AH=08h	[2.09] Get Key without Echo
+
+	Reads a key fron the console input, without echoing it to the
+	console output.  The read character is returned in AL.
+
+
+INT 21h AH=09h	[2.01] Write DOS String to Console
+
+	Writes a DOS $-terminated string in DS:DX to the console.
+
+
+INT 21h AH=0Bh	[2.00] Check Keyboard
+
+	Returns AL=FFh if there is a keystroke waiting (which can then
+	be read with INT 21h, AH=01h or AH=08h), otherwise AL=00h.
+
+
+INT 21h AH=30h	[2.00] Check DOS Version
+
+	This function returns AX=BX=CX=DX=0, corresponding to a
+	hypothetical "DOS 0.0", but the high parts of EAX-EBX-ECX-EDX
+	spell "SYSLINUX":
+
+	EAX=59530000h EBX=4C530000h ECX=4E490000h EDX=58550000h
+
+	This function can thus be used to distinguish running on
+	Syslinux from running on DOS.
+
+
+	++++ SYSLINUX-SPECIFIC API CALLS ++++
+
+Syslinux-specific API calls are executed using INT 22h, with a
+function number in AX.  INT 22h is used by DOS for internal purposes;
+do not execute INT 22h under DOS.
+
+DOS-compatible function INT 21h, AH=30h can be used to detect if the
+Syslinux API calls are available.
+
+Any register not specifically listed as modified is preserved;
+however, future versions of Syslinux may add additional output
+registers to existing calls.
+
+All calls return CF=0 on success, CF=1 on failure.  The noted outputs
+apply if CF=0 only unless otherwise noted.  All calls clobber the
+arithmetric flags (CF, PF, AF, ZF, SF and OF) but leave all other
+flags unchanged unless otherwise noted.
+
+
+AX=0001h [2.00]	Get Version
+
+	Input:	AX	0001h
+	Output:	AX	number of INT 22h API functions available
+		CH	Syslinux major version number
+		CL	Syslinux minor version number
+		DL	Syslinux derivative ID (e.g. 32h = PXELINUX)
+		ES:SI	Syslinux version string
+		ES:DI	Syslinux copyright string
+
+	This API call returns the Syslinux version and API
+	information.
+
+	Note: before version 3.86, the version string had a leading CR LF
+	and the copyright string had a leading space.  The strings might
+	still contain trailing CR and/or LF.
+
+
+AX=0002h [2.01] Write String
+
+	Input:	AX	0002h
+		ES:BX	null-terminated string
+	Output:	None
+
+	Writes a null-terminated string on the console.
+
+
+AX=0003h [2.01] Run command
+
+	Input:	AX	0003h
+		ES:BX	null-terminated command string
+	Output:	Does not return
+
+	This API call terminates the program and executes the command
+	string as if the user had entered it at the Syslinux command
+	line.  This API call does not return.
+
+
+AX=0004h [2.01] Run default command
+
+	Input:	AX	0004h
+	Output:	Does not return
+
+	This API call terminates the program and executes the default
+	command string as if the user had pressed Enter alone on the
+	Syslinux command line.  This API call does not return.
+
+
+AX=0005h [2.00] Force text mode
+
+	Input:	AX	0005h
+	Output:	None
+
+	If the screen was in graphics mode (due to displaying a splash
+	screen using the <Ctrl-X> command in a message file, or
+	similar), return to text mode.
+
+
+AX=0006h [2.08] Open file
+
+	Input:	AX	0006h
+		ES:SI	null-terminated filename
+	Output:	SI	file handle
+		EAX	length of file in bytes, or -1
+		CX	file block size
+
+	Open a file for reading.  The exact syntax of the filenames
+	allowed depends on the particular Syslinux derivative.
+
+	The Syslinux file system is block-oriented.  The size of a
+	block will always be a power of two and no greater than 16K.
+
+	Note: Syslinux considers a zero-length file to be nonexistent.
+
+	In 3.70 or later, EAX can contain -1 indicating that the file
+	length is unknown.
+
+	32-BIT VERSION:
+
+	int cs_pm->open_file(const char *filename, struct com32_filedata *data)
+
+	filename - null-terminated filename
+	data	 - pointer to a file data buffer
+
+	Returns the file handle, or -1 on failure.
+	The file data buffer contains block size and file size.
+
+
+AX=0007h [2.08] Read file
+
+	Input:	AX	0007h
+		SI	file handle
+		ES:BX	buffer
+		CX	number of blocks to read
+	Output:	SI	file handle, or 0 if EOF was reached
+		ECX	number of bytes read [3.70]
+
+	Read blocks from a file.  Note that the file handle that is
+	returned in SI may not be the same value that was passed in.
+
+	If end of file was reached (SI=0), the file was automatically
+	closed.
+
+	In 3.70 or later, ECX returns the number of bytes read.  This
+	will always be a multiple of the block size unless EOF is
+	reached.
+
+	The address of the buffer (ES:BX) should be at least 512-byte
+	aligned.  Syslinux guarantees at least this alignment for the
+	COMBOOT load segment or the COM32 bounce buffer.
+
+	Keep in mind that a "file" may be a TFTP connection, and that
+	leaving a file open for an extended period of time may result
+	in a timeout.
+
+	WARNING: Calling this function with an invalid file handle
+	will probably crash the system.
+
+	32-BIT VERSION:
+
+	size_t cs_pm->read_file(uint16_t *handle, void *buf, size_t blocks)
+
+	handle	- file handle (input and output, set to zero on end of file)
+	buf	- buffer to write to
+	blocks	- number of blocks to read
+
+	Returns number of bytes read, or 0 on failure.
+
+
+AX=0008h [2.08] Close file
+
+	Input:	AX	0008h
+		SI	file handle
+	Output:	None
+
+	Close a file before reaching the end of file.
+
+	WARNING: Calling this function with an invalid file handle
+	will probably crash the system.
+
+	32-BIT VERSION:
+
+	void cs_pm->close_file(uint16_t handle)
+
+	handle	- file handle to close
+
+
+AX=0009h [2.00] Call PXE Stack [PXELINUX ONLY]
+
+	Input:	AX	0009h
+		BX	PXE function number
+		ES:DI	PXE parameter structure buffer
+	Output:	AX	PXE return status code
+
+	Invoke an arbitrary PXE stack function.  On SYSLINUX/ISOLINUX,
+	this function returns with an error (CF=1) and no action is
+	taken.  On PXELINUX, this function always returns with CF=0
+	indicating that the PXE stack was successfully invoked; check
+	the status code in AX and in the first word of the data buffer
+	to determine if the PXE call succeeded or not.
+
+	The PXE stack will have the UDP stack OPEN; if you change that
+	you cannot call any of the file-related API functions, and
+	must restore UDP OPEN before returning to PXELINUX.
+
+	PXELINUX reserves UDP port numbers from 49152 to 65535 for its
+	own use; port numbers below that range is available.
+
+
+AX=000Ah [2.00]	Get Derivative-Specific Information
+
+	[SYSLINUX, EXTLINUX]
+	Input:	AX	000Ah
+		CL	9 (to get a valid return in CL for all versions)
+	Output:	AL	31h (SYSLINUX), 34h (EXTLINUX)
+		DL	drive number
+		CL	sector size as a power of 2 (9 = 512 bytes) [3.35]
+		CH	mode [3.73]
+			1 = CBIOS mode
+			2 = EBIOS mode
+		ES:BX	pointer to partition table entry (if DL >= 80h)
+		FS:SI	pointer to initial ES:DI value [3.53]
+		GS:DI	pointer to partition offset (QWORD) [4.00]
+
+		Note: This function was broken in EXTLINUX 3.00-3.02.
+
+		On boot, ES:DI is supposed to point to the BIOS $PnP
+		structure, although in practice most operating systems
+		will search for it in memory.  However, preserving
+		this while chainloading is probably a good idea.
+
+		Note that FS:SI is a pointer to a memory location
+		containing the original ES:DI value, not the value
+		itself.
+
+
+	[PXELINUX]
+	Input:	AX	000Ah
+	Output:	AL	32h (PXELINUX)
+		DX	PXE API version detected (DH=major, DL=minor)
+		ECX	Local IP number (network byte order) [3.85]
+		ES:BX	pointer to PXENV+ or !PXE structure
+		FS:SI	pointer to original stack with invocation record
+		GS:DI	pointer to network information [4.00]
+
+		Note: DX notes the API version detected by PXELINUX,
+		which may be more conservative than the actual version
+		available.  For exact information examine the API
+		version entry in the PXENV+ structure, or the API
+		version entries in the ROMID structures pointed from
+		the !PXE structure.
+
+		PXELINUX will use, and provide, the !PXE structure
+		over the PXENV+ structure.  Examine the structure
+		signature to determine which particular structure was
+		provided.
+
+		The FS:SI pointer points to the top of the original stack
+		provided by the PXE stack, with the following values
+		pushed at the time PXELINUX is started:
+
+		[fs:si+0]	GS		<- top of stack
+		[fs:si+2]	FS
+		[fs:si+4]	ES
+		[fs:si+6]	DS
+		[fs:si+8]	EDI
+		[fs:si+12]	ESI
+		[fs:si+16]	EBP
+		[fs:si+20]	-
+		[fs:si+24]	EBX
+		[fs:si+28]	EDX
+		[fs:si+32]	ECX
+		[fs:si+36]	EAX
+		[fs:si+40]	EFLAGS
+		[fs:si+44]	PXE return IP	<- t.o.s. when PXELINUX invoked
+		[fs:si+46]	PXE return CS
+
+		GS:DI points to a structure of the following form:
+
+		[gs:di+0]	4		- IPv4
+		[gs:di+4]	My IP
+		[gs:di+8]	Boot server IP
+		[gs:di+12]	Gateway IP
+		[gs:di+16]	Netmask
+
+	[ISOLINUX]
+	Input:	AX	000Ah
+	Output:	AL	33h (ISOLINUX)
+		DL	drive number
+		CL	11 (sector size as a power of 2) [3.35]
+		CH	mode [3.73]
+			0 = El Torito
+			1 = Hybrid (hard disk), CBIOS mode
+			2 = Hybrid (hard disk), EBIOS mode
+		ES:BX	pointer to El Torito spec packet
+		FS:SI	pointer to initial ES:DI value [3.53]
+		GS:DI	pointer to partition offset (QWORD) [4.00]
+
+		Note: Some very broken El Torito implementations do
+		not provide the spec packet information.  If so, ES:BX
+		may point to all zeroes or to garbage.  Call INT 13h,
+		AX=4B01h to obtain the spec packet directly from the
+		BIOS if necessary.
+
+
+AX=000Bh [2.00]	Get Serial Console Configuration
+
+	Input:	AX	000Bh
+	Output:	DX	serial port I/O base (e.g. 3F8h = COM1...)
+		CX	baud rate divisor (1 = 115200 bps, 2 = 57600 bps...)
+		BX	flow control configuration bits (see syslinux.txt)
+			-> bit 15 is set if the video console is disabled
+
+	If no serial port is configured, DX will be set to 0 and the
+	other registers are undefined.
+
+
+AX=000Ch [2.00]	Perform final cleanup
+	Input:	AX	000Ch
+		DX	derivative-specific flags (0000h = clean up all)
+	Output:	None
+
+	This routine performs any "final cleanup" the boot loader
+	would normally perform before loading a kernel, such as
+	unloading the PXE stack in the case of PXELINUX.  AFTER
+	INVOKING THIS CALL, NO OTHER API CALLS MAY BE INVOKED, NOR MAY
+	THE PROGRAM TERMINATE AND RETURN TO THE BOOT LOADER.  This
+	call basically tells the boot loader "get out of the way, I'll
+	handle it from here."
+
+	For COM32 images, the boot loader will continue to provide
+	interrupt and BIOS call thunking services as long its memory
+	areas (0x0800-0xffff, 0x100000-0x100fff) are not overwritten.
+	MAKE SURE TO DISABLE INTERRUPTS, AND INSTALL NEW GDT AND IDTS
+	BEFORE OVERWRITING THESE MEMORY AREAS.
+
+	The permissible values for DX is an OR of these values:
+
+	SYSLINUX:	0000h	Normal cleanup
+
+	PXELINUX:	0000h	Normal cleanup
+			0003h	Keep UNDI and PXE stacks loaded
+
+	ISOLINUX:	0000h	Normal cleanup
+
+	EXTLINUX:	0000h	Normal cleanup
+
+	All other values are undefined, and may have different
+	meanings in future versions of Syslinux.
+
+
+AX=000Dh [2.08]	Cleanup and replace bootstrap code
+	Input:	AX	000Dh
+		DX	derivative-specific flags (see previous function)
+		EDI	bootstrap code (linear address, can be in high memory)
+		ECX	bootstrap code length in bytes (must fit in low mem)
+		EBX(!)	initial value of EDX after bootstrap
+		ESI	initial value of ESI after bootstrap
+		DS	initial value of DS after bootstrap
+	Output:	Does not return
+
+	This routine performs final cleanup, then takes a piece of
+	code, copies it over the primary bootstrap at address 7C00h,
+	and jumps to it.  This can be used to chainload boot sectors,
+	MBRs, bootstraps, etc.
+
+	Normal boot sectors expect DL to contain the drive number,
+	and, for hard drives (DL >= 80h) DS:SI to contain a pointer to
+	the 16-byte partition table entry.  The memory between
+	600h-7FFh is available to put the partition table entry in.
+
+	For PXELINUX, if the PXE stack is not unloaded, all registers
+	(except DS, ESI and EDX) and the stack will be set up as they
+	were set up by the PXE ROM.
+
+
+AX=000Eh [2.11]	Get configuration file name
+	Input:	AX	0000Eh
+	Output:	ES:BX	null-terminated file name string
+
+	Returns the name of the configuration file.  Note that it is
+	possible that the configuration file doesn't actually exist.
+
+
+AX=000Fh [3.00] Get IPAPPEND strings [PXELINUX]
+	Input:  AX	000Fh
+	Output:	CX	number of strings (currently 2)
+		ES:BX	pointer to an array of NEAR pointers in
+			the same segment, one for each of the above
+			strings
+
+	Returns the same strings that the "ipappend" option would have
+	added to the command line, one for each bit of the "ipappend"
+	flag value, so entry 0 is the "ip=" string and entry 1 is the
+	"BOOTIF=" string.
+
+
+AX=0010h [3.00] Resolve hostname [PXELINUX]
+	Input:  AX	0010h
+		ES:BX	pointer to null-terminated hostname
+	Output:	EAX	IP address of hostname (zero if not found)
+
+	Queries the DNS server(s) for a specific hostname.  If the
+	hostname does not contain a dot (.), the local domain name
+	is automatically appended.
+
+	This function only return CF=1 if the function is not
+	supported.  If the function is supported, but the hostname did
+	not resolve, it returns with CF=0, EAX=0.
+
+	The IP address is returned in network byte order, i.e. if the
+	IP address is 1.2.3.4, EAX will contain 0x04030201.  Note that
+	all uses of IP addresses in PXE are also in network byte order.
+
+
+AX=0011h [3.05] Obsoleted in 3.80
+
+
+AX=0012h [3.50] Cleanup, shuffle and boot
+	Input:	AX	0012h
+		DX	derivative-specific flags (see function 000Ch)
+		ES:DI	shuffle descriptor list (must be in low memory)
+		CX	number of shuffle descriptors
+		EBX(!)	initial value of EDX after bootstrap
+		ESI	initial value of ESI after bootstrap
+		DS	initial value of DS after bootstrap
+		EBP	CS:IP of routine to jump to
+	Output:	Does not return
+		(if CX is too large the routine returns with CF=1)
+
+	This routine performs final cleanup, then performs a sequence
+	of copies, and jumps to a specified real mode entry point.
+	This is a more general version of function 000Dh, which can
+	also be used to load other types of programs.
+
+	The copies must not touch memory below address 7C00h.
+
+	ES:DI points to a list of CX descriptors each of the form:
+
+		Offset	Size	Meaning
+		 0	dword	destination address
+		 4	dword	source address
+		 8	dword	length in bytes
+
+	The copies are overlap-safe, like memmove().
+
+	Starting in version 3.50, if the source address is -1
+	(FFFFFFFFh) then the block specified by the destination
+	address	and the length is set to all zero.
+
+	Starting in version 3.50, if the destination address is -1
+	(FFFFFFFFh) then the data block is loaded as a new set of
+	descriptors, and processing is continued (and unprocessed
+	descriptors are lost, this is thus typically only used as the
+	last descriptor in a block.)  The block must still fit in the
+	internal descriptor buffer (see function 0011h), but can, of
+	course, itself chain another block.
+
+
+	Normal boot sectors expect DL to contain the drive number,
+	and, for hard drives (DL >= 80h) DS:SI to contain a pointer to
+	the 16-byte partition table entry.  The memory between
+	600h-7FFh is available to put the partition table entry in.
+
+	For PXELINUX, if the PXE stack is not unloaded, all registers
+	(except DS, ESI and EDX) and the stack will be set up as they
+	were set up by the PXE ROM.
+
+	This interface was probably broken before version 3.50.
+
+
+AX=0013h [3.08] Idle loop call
+	Input:	AX	0013h
+	Output:	None
+
+	Call this routine while sitting in an idle loop.  It performs
+	any periodic activities required by the filesystem code.  At
+	the moment, this is a no-op on all derivatives except
+	PXELINUX, where it executes PXE calls to answer ARP queries.
+
+	Starting with version 3.10, this API call harmlessly returns
+	failure (CF=1) if invoked on a platform which does not need
+	idle calls.  Additionally, it's safe to call this API call on
+	previous Syslinux versions (2.00 or later); it will just
+	harmlessly fail.  Thus, if this call returns failure (CF=1),
+	it means that there is no technical reason to call this
+	function again, although doing so is of course safe.
+
+
+AX=0014h [3.10] Local boot [PXELINUX, ISOLINUX]
+	Input:	AX	0014h
+		DX	Local boot parameter
+	Output:	Does not return
+
+	This function invokes the equivalent of the "localboot"
+	configuration file option.  The parameter in DX is the same
+	parameter as would be entered after "localboot" in the
+	configuration file; this parameter is derivative-specific --
+	see syslinux.txt for the definition.
+
+
+AX=0015h [3.10] Get feature flags
+	Input:	AX	0015h
+	Output:	ES:BX	pointer to flags in memory
+		CX	number of flag bytes
+
+	This function reports whether or not this Syslinux version and
+	derivative supports specific features.  Keep in mind that
+	future versions might have more bits; remember to treat any
+	bits beyond the end of the array (as defined by the value in
+	CX) as zero.
+
+	Currently the following feature flag is defined:
+
+	Byte	Bit	Definition
+	----------------------------------------------------
+	0	0	Local boot (AX=0014h) supported
+		1	Idle loop call (AX=0013h) is a no-op
+
+	All other flags are reserved.
+
+
+AX=0016h [3.10] Run kernel image
+	Input:	AX	0016h
+		DS:SI	Filename of kernel image (zero-terminated string)
+		ES:BX	Command line (zero-terminated string)
+		ECX	IPAPPEND flags [PXELINUX]
+		EDX	Type of file (since 3.50)
+	Output:	Does not return if successful; returns with CF=1 if
+		the kernel image is not found.
+
+	This function is similiar to AX=0003h Run command, except that
+	the filename and command line are treated as if specified in a
+	KERNEL and APPEND statement of a LABEL statement, which means:
+
+	- The filename has to be exact; no variants are tried;
+	- No global APPEND statement is applied;
+	- ALLOWOPTIONS and IMPLICIT statements in the configuration
+	  file do not apply.  It is therefore important that the
+	  COMBOOT module doesn't allow the end user to violate the
+	  intent of the administrator.
+
+	Additionally, this function returns with a failure if the file
+	doesn't exist, instead of returning to the command line.  (It
+	may still return to the command line if the image is somehow
+	corrupt, however.)
+
+	The file types are defined as follows:
+
+		    Equivalent
+	EDX	Config	Extensions	Type of file
+	0	KERNEL			Determined by filename extension
+	1	LINUX	none		Linux kernel image
+	2	BOOT	.bs .bin	Bootstrap program
+	3	BSS	.bss		Boot sector with patch [SYSLINUX]
+	4	PXE	.0		PXE Network Bootstrap Prog [PXELINUX]
+	5	FDIMAGE	.img		Floppy disk image [ISOLINUX]
+	6	COMBOOT	.com .cbt	16-bit COMBOOT program
+	7	COM32	.c32		COM32 program
+	8	CONFIG			Configuration file
+
+
+AX=0017h [3.30] Report video mode change
+	Input:	AX	0017h
+		BX	Video mode flags
+			Bit 0:	graphics mode
+			Bit 1:	non-default mode
+			Bit 2:	VESA mode
+			Bit 3:	text functions not supported
+		CX	For graphics modes, pixel columns
+		DX	For graphics modes, pixel rows
+	Output:	None
+
+	This function is used to report video mode changes to
+	Syslinux.  It does NOT actually change the video mode, but
+	rather, allows Syslinux to take appropriate action in response
+	to a video mode change.  Modes that cannot be exited either
+	with the conventional BIOS mode set command (INT 10h, AH=00h)
+	or the VESA VBE mode set command (INT 10h, AX=4F02h) should
+	not be used.
+
+	This function returns with a failure if BX contains any bits
+	which are undefined in the current version of Syslinux.
+
+	The following bits in BX are currently defined:
+
+	Bit 0: graphics mode
+
+		Indicates that the mode is a graphics mode, as opposed
+		to a text mode.
+
+	Bit 1: non-standard mode
+
+		A non-standard mode is any mode except text mode and
+		graphics mode 0012h (VGA 640x480, 16 color.)
+
+	Bit 2: VESA mode
+
+		This mode is a VESA mode, and has to be exited with
+		the VESA VBE API (INT 10h, AX=4F02h) as opposed to the
+		conventional BIOS API (INT 10h, AH=00h).
+
+	Bit 3: Text functions not supported
+
+		This indicates that the BIOS text output functions
+		(INT 10h, AH=02h, 03h, 06h, 09h, 0Eh, 11h) don't work.
+		If this bit is set, Syslinux will reset the mode
+		before printing any characters on the screen.
+
+		This is common for VESA modes.
+
+
+AX=0018h [3.30]	Query custom font
+	Input:	AX	0018h
+	Output:	AL	Height of custom font in scan lines, or zero
+		ES:BX	Pointer to custom font in memory
+
+	This call queries if a custom display font has been loaded via
+	the "font" configuration file command.  If no custom font has
+	been loaded, AL contains zero.
+
+
+AX=0019h [3.50] Read disk [SYSLINUX, ISOLINUX, EXTLINUX]
+	Input:	AX	0019h
+		EDX	Sector number (LSW)
+		ESI	Sector number (MSW) [4.00]
+		EDI	Reserved - MUST BE ZERO
+		CX	Sector count
+		ES:BX	Buffer address
+	Output:	None
+
+	Read disk blocks from the active filesystem (partition); for
+	disks, sector number zero is the boot sector.  For ISOLINUX,
+	this call reads the CD-ROM.
+
+	For compatiblity with all systems, the buffer should
+	*neither* cross 64K boundaries, *nor* wrap around the segment.
+
+	This routine reports "boot failed" (and does not return) on
+	disk error.
+
+	Note: for ISOLINUX in hybrid mode, this call uses simulated
+	2048-byte CD-ROM sector numbers.
+
+
+AX=001Ah [3.50] Obsoleted in 3.80
+
+
+AX=001Bh [3.50]	Obsoleted in 3.80
+
+
+AX=001Ch [3.60] Get pointer to auxilliary data vector
+	Input:	AX	001Ch
+	Output:	ES:BX	Auxilliary data vector
+		CX	Size of the ADV (currently 500 bytes)
+
+	The auxillary data vector is a tagged data structure used
+	to carry a small amount of information (up to 500 bytes) from
+	one boot to another.
+
+
+AX=001Dh [3.60]	Write auxilliary data vector
+	Input:	AX	001Dh
+	Output:	None
+
+	Write the auxilliary data vector back to disk.  Returns
+	failure for non-disk-based derivatives unless the "auxdata"
+	configuration command is used to specify a disk location
+	(not yet implemented.)
+
+	In a future version, PXELINUX may end up attempting to save
+	the ADV on the server via TFTP write.
+
+
+AX=001Eh [3.74] Keyboard remapping table
+	Input:	AX	001Eh
+		DX	0000h - all other values reserved
+	Output:	AX	format version (1)
+		CX	length in bytes (256)
+		ES:BX	pointer to keyboard table
+
+	This call queries the keyboard remapping table.  For the current
+	version, the format code is always 1 and the length is always
+	256.  This version can be updated simply by overwriting the version
+	in memory; this may not be true in the future.
+
+
+AX=001Fh [3.74]	Get current working directory
+	Input:	AX	0001Fh
+	Output:	ES:BX	null-terminated directory name string
+
+	Returns the current working directory.
+
+
+AX=0020h [3.74] Obsoleted in 4.00
+AX=0021h [3.74] Obsoleted in 4.00
+AX=0022h [3.74] Obsoleted in 4.00
+
+	These three functions provided opendir/readdir/closedir
+	functionality in the late 3.xx series.  They have been
+	replaced by the protected-mode interface.
+
+
+AX=0023h [3.80] Get shuffler parameters
+	Input:	AX	0023h
+	Output:	CX	size of shuffler "safe area" in bytes
+		Other registers reserved for future use
+
+	This call gives the size of the required shuffler "safe area",
+	in bytes; for call 0024h.  In the future, it may provide
+	additional parameters.
+
+
+AX=0024h [3.80] Cleanup, shuffle and boot, raw version
+	Input:	AX	0024h
+		DX	derivative-specific flags (see function 000Ch)
+		EDI	shuffle descriptor list safe area
+		ESI	shuffle descriptor list source
+		ECX	byte count of shuffle descriptor list
+	Output:	Does not return
+
+	This routine performs final cleanup, then performs a sequence
+	of copies, and jumps to a specified real mode entry point.
+	This is a more general version of function 000Dh, which can
+	also be used to load other types of programs.
+
+	Unlike previous obsolete versions of this function, there are
+	no restrictions that copies must not touch memory below
+	address 7C00h.  Either the shuffle descriptor list or the safe
+	area (or both) may be located in high memory.
+
+	ESI points to a list of descriptors each of the form:
+
+		Offset	Size	Meaning
+		 0	dword	destination address
+		 4	dword	source address (-1 = zero)
+		 8	dword	length in bytes (0 = end of list)
+
+	The copies are overlap-safe, like memmove().
+
+	Before actually executing the move list, the list is moved to
+	the address specified in EDI.  The caller is responsibe to
+	ensure that the moved descriptor list plus a "safe area"
+	immediately afterwards (the size of which is specified by
+	function 0023h) is not disturbed by the copy sequence.  It is,
+	however, safe to overwrite descriptors already consumed.
+
+	If the source address is -1 (FFFFFFFFh) then the block
+	specified by the destination address and the length is set to
+	all zero.
+
+	The list is terminated by an entry with length 0.  For that
+	entry, the destination is used as an entry point, and the
+	source represents the type of entry point:
+
+		0	16-bit protected mode (dst is CS.base)
+		1	Flat 32-bit protected mode (dst is EIP)
+
+	This routine does not set up any GPR register state
+	whatsoever, including stack.  It is the responsibility of the
+	caller to make sure the entry point provided sets up any
+	registers needed.
+
+	For mode 0 (16-bit real mode), EAX will contain CR0 with bit 0
+	masked out, suitable for loading into CR0 to immediately enter
+	real mode.  Note: if real-mode entry is planned,
+	(CS.base & 0xfff0000f) should == 0 for compatibility with KVM,
+	and possibly other virtualization solutions.
+
+	In both mode 0 and mode 1, the data segments will be loaded
+	with read/write data segments, matching the respective code
+	segment.  For mode 0, B=0 and the limits will be 64K, for mode
+	1, B=1 and the limits will be 4 GB.

+For creators of Linux distributions:

+Syslinux is a notoriously hard program to debug, since it runs outside

+
+To rebuild the installer programs *only*, starting from a freshly

+EXTLINUX is a new Syslinux derivative, which boots from a Linux
+ext2/ext3 filesystem.
+
+It works the same way as SYSLINUX (see doc/syslinux.txt), with a few
+slight modifications.
+
+1. The installer is run on a *mounted* filesystem.  Run the extlinux
+   installer on the directory in which you want extlinux installed:
+
+	extlinux --install /boot
+
+   Specify --install (-i) to install for the first time, or
+   --update (-U) to upgrade a previous installation.
+
+   NOTE: this doesn't have to be the root directory of a filesystem.
+   If /boot is a filesystem, you can do:
+
+	mkdir -p /boot/extlinux
+	extlinux --install /boot/extlinux
+
+   ... to create a subdirectory and install extlinux in it.
+   /boot/extlinux is the recommended location for extlinux.
+
+
+2. The configuration file is called "extlinux.conf", and is expected
+   to be found in the same directory as extlinux is installed in.
+
+
+3. Pathnames can be absolute or relative; if absolute (with a leading
+   slash), they are relative to the root of the filesystem on which
+   extlinux is installed (/boot in the example above), if relative,
+   they are relative to the extlinux directory.
+
+   extlinux supports subdirectories, but the total path length is
+   limited to 511 characters.
+
+
+4. EXTLINUX now supports symbolic links.  However, extremely long
+   symbolic links might hit the pathname limit.  Also, please note
+   that absolute symbolic links are interpreted from the root *of the
+   filesystem*, which might be different from how the running system
+   would interpret it (e.g. in the case of a separate /boot
+   partition.)  Therefore, use relative symbolic links if at all
+   possible.
+
+
+5. EXTLINUX now has "boot-once" support.  The boot-once information is
+   stored in an on-disk datastructure, part of extlinux.sys, called
+   the "Auxillary Data Vector".  The Auxilliary Data Vector is also
+   available to COMBOOT/COM32 modules that want to store small amounts
+   of information.
+
+   To set the boot-once information, do:
+
+	extlinux --once 'command' /boot/extlinux
+
+   where 'command' is any command you could enter at the Syslinux
+   command line.  It will be executed on the next boot and then
+   erased.
+
+   To clear the boot-once information, do:
+
+	extlinux --clear-once /boot/extlinux
+
+   If EXTLINUX is used on a RAID-1, this is recommended, since under
+   certain circumstances a RAID-1 rebuild can "resurrect" the
+   boot-once information otherwise.
+
+   To clear the entire Auxillary Data Vector, do:
+
+	extlinux --reset-adv /boot/extlinux
+
+   This will erase all data stored in the ADV, including boot-once.
+
+   The --once, --clear-once, and --reset-adv commands can be combined
+   with --install or --update, if desired.  The ADV is preserved
+   across updates, unless --reset-adv is specified.
+
+
+Note that EXTLINUX installs in the filesystem partition like a
+well-behaved bootloader :)  Thus, it needs a master boot record in the
+partition table; the mbr.bin shipped with Syslinux should work well.
+To install it just do:
+
+	cat mbr.bin > /dev/XXX
+
+... where /dev/XXX is the appropriate master device, e.g. /dev/hda,
+and make sure the correct partition in set active.
+
+
+If you have multiple disks in a software RAID configuration, the
+preferred way to boot is:
+
+- Create a separate RAID-1 partition for /boot.  Note that the Linux
+  RAID-1 driver can span as many disks as you wish.
+
+- Install the MBR on *each disk*, and mark the RAID-1 partition
+  active.
+
+- Run "extlinux --raid --install /boot" to install extlinux.  This
+  will install it on all the drives in the RAID-1 set, which means
+  you can boot any combination of drives in any order.
+
+
+
+It is not required to re-run the extlinux installer after installing
+new kernels.  If you are using ext3 journalling, however, it might be
+desirable to do so, since running the extlinux installer will flush
+the log.  Otherwise a dirty shutdown could cause some of the new
+kernel image to still be in the log.  This is a general problem for
+boot loaders on journalling filesystems; it is not specific to
+extlinux.  The "sync" command does not flush the log on the ext3
+filesystem.
+
+
+The Syslinux Project boot loaders support chain loading other
+operating systems via a separate module, chain.c32 (located in
+com32/modules/chain.c32).  To use it, specify a LABEL in the
+configuration file with KERNEL chain.c32 and APPEND [hd|fd]<number>
+[<partition>]
+
+For example:
+
+# Windows CE/ME/NT, a very dense operating system.
+# Second partition (2) on the first hard disk (hd0);
+# Linux would *typically* call this /dev/hda2 or /dev/sda2.
+LABEL cement
+	KERNEL chain.c32
+	APPEND hd0 2

+			  GPT boot protocol
+
+There are two ways to boot a GPT-formatted disk on a BIOS system.
+Hybrid booting, and the new GPT-only booting protocol originally
+proposed by the author, and later adopted by the T13 committee in
+slightly modified form.
+
+
+	*** Hybrid booting ***
+
+Hybrid booting uses a standard MBR, and has bootable ("active")
+partitions present, as partitions, in the GPT PMBR sector.  This means
+the PMBR, instead of containing only one "protective" partition (type
+EE), may contain up to three partitions: a protective partition (EE)
+*before* the active partition, the active partition, and a protective
+partition (EE) *after* the active partition.  The active partition is
+limited to the first 2^32 sectors (2 TB) of the disk.
+
+All partitions, including the active partition, should have GPT
+partition entries.  Thus, changing which partition is active does NOT
+change the GPT partition table.
+
+This is the only known way to boot Microsoft operating systems from a
+GPT disk with BIOS firmware.
+
+
+	*** New protocol ***
+
+This defines the T13-approved protocol for GPT partitions with BIOS
+firmware.  It maintains backwards compatibility to the extent
+possible.  It is implemented by the file mbr/gptmbr.bin.
+
+The (P)MBR format is the normal PMBR specified in the UEFI
+documentation, with the first 440 bytes used for the boot code.  The
+partition to be booted is marked by setting bit 2 in the GPT Partition
+Entry Attributes field (offset 48); this bit is reserved by the UEFI
+Forum for "Legacy BIOS Bootable".
+
+
+    -> The handover protocol
+
+The PMBR boot code loads the first sector of the bootable partition,
+and passes in DL=<disk number>, ES:DI=<pointer to $PnP>, sets EAX to
+0x54504721 ("!GPT") and points DS:SI to a structure of the following
+form:
+
+	Offset	Size	Contents
+	---------------------------------------------------------
+	  0	  1	0x80 (this is a bootable partition)
+	  1	  3	CHS of partition (using INT 13h geometry)
+	  4	  1	0xED (partition type: synthetic)
+	  5	  3	CHS of partition end
+	  8	  4	Partition start LBA
+	 12	  4	Partition end LBA
+	 16	  4	Length of the GPT entry
+	 20	varies	GPT partition entry
+
+The CHS information is optional; gptmbr.bin currently does *NOT*
+calculate them, and just leaves them as zero.
+
+Bytes 0-15 matches the standard MBR handover (DS:SI points to the
+partition entry), except that the information is provided
+synthetically.  The MBR-compatible fields are directly usable if they
+are < 2 TB, otherwise these fields should contain 0xFFFFFFFF and the
+OS will need to understand the GPT partition entry which follows the
+MBR one.  The "!GPT" magic number in EAX and the 0xED partition type
+also informs the OS that the GPT partition information is present.
+
+Syslinux 4.00 and later fully implements this protocol.

+
+       A bootloader for Linux using ISO 9660/El Torito CD-ROMs
+
+       Copyright 1994-2008 H. Peter Anvin - All Rights Reserved
+
+This program is provided under the terms of the GNU General Public
+License, version 2 or, at your option, any later version.  There is no
+warranty, neither expressed nor implied, to the function of this
+program.  Please see the included file COPYING for details.
+
+----------------------------------------------------------------------
+
+ISOLINUX is a boot loader for Linux/i386 that operates off ISO 9660/El
+Torito CD-ROMs in "no emulation" mode.  This avoids the need to create
+an "emulation disk image" with limited space (for "floppy emulation")
+or compatibility problems (for "hard disk emulation".)
+
+This documentation isn't here yet, but here is enough that you should
+be able to test it out:
+
+Make sure you have a recent enough version of mkisofs.  I recommend
+mkisofs 1.13 (distributed with cdrecord 1.9), but 1.12 might work as
+well (not tested.)
+
+To create an image, create a directory called "isolinux" (or, if you
+prefer, "boot/isolinux") underneath the root directory of your ISO
+image master file tree.  Copy isolinux.bin, a config file called
+"isolinux.cfg" (see syslinux.txt for details on the configuration
+file), and all necessary files (kernels, initrd, display files, etc.)
+into this directory, then use the following command to create your ISO
+image (add additional options as appropriate, such as -J or -R):
+
+	mkisofs -o <isoimage> \
+		-b isolinux/isolinux.bin -c isolinux/boot.cat \
+		-no-emul-boot -boot-load-size 4 -boot-info-table \
+		<root-of-iso-tree>
+
+(If you named the directory boot/isolinux that should of course be
+-b boot/isolinux/isolinux.bin -c boot/isolinux/boot.cat.)
+
+ISOLINUX resolves pathnames the following way:
+
+- A pathname consists of names separated by slashes, Unix-style.
+- A leading / means it searches from the root directory; otherwise the
+  search is from the isolinux directory (think of this as the "current
+  directory".)
+- . and .. in pathname searches are not supported.
+- The maximum length of any pathname is 255 characters.
+
+Note that ISOLINUX only uses the "plain" ISO 9660 filenames, i.e. it
+does not support Rock Ridge or Joliet filenames.  It can still be used
+on a disk which uses Rock Ridge and/or Joliet extensions, of course.
+Under Linux, you can verify the plain filenames by mounting with the
+"-o norock,nojoliet" option to the mount command.  Note, however, that
+ISOLINUX does support "long" (level 2) ISO 9660 plain filenames, so if
+compatibility with short-names-only operating systems like MS-DOS is
+not an issue, you can use the "-l" or "-iso-level 2" option to mkisofs
+to generate long (up to 31 characters) plain filenames.
+
+ISOLINUX does not support discontiguous files, interleaved mode, or
+logical block and sector sizes other than 2048.  This should normally
+not be a problem.
+
+ISOLINUX is by default built in two versions, one version with extra
+debugging messages enabled.  If you are having problems with ISOLINUX,
+I would greatly appreciate if you could try out the debugging version
+(isolinux-debug.bin) and let me know what it reports.  The debugging
+version does not include hybrid mode support (see below.)
+
+
+      ++++ NOTE ON THE CONFIG FILE DIRECTORY ++++
+
+ISOLINUX will search for the config file directory in the order
+/boot/isolinux, /isolinux, /.  The first directory that exists is
+used, even if it contains no files.  Therefore, please make sure that
+these directories don't exist if you don't want ISOLINUX to use them.
+
+
+      ++++ HYBRID CD-ROM/HARD DISK MODE ++++
+
+Starting in version 3.72, ISOLINUX supports a "hybrid mode" which can
+be booted from either CD-ROM or from a device which BIOS considers a
+hard disk or ZIP disk, e.g. a USB key or similar.
+
+To enable this mode, the .iso image should be postprocessed with the
+"isohybrid" script from the utils directory:
+
+	isohybrid filename.iso
+
+This script creates the necessary additional information to be able to
+boot in hybrid mode.  It also pads out the image to an even multiple
+of 1 MB.
+
+This image can then be copied using any raw disk writing tool (on Unix
+systems, typically "dd" or "cat") to a USB disk, or written to a
+CD-ROM using standard CD burning tools.
+
+The ISO 9660 filesystem is encapsulated in a partition (which starts
+at offset zero, which may confuse some systems.)  This makes it
+possible for the operating system, once booted, to use the remainder
+of the device for persistent storage by creating a second partition.
+
+
+      ++++ BOOTING DOS (OR OTHER SIMILAR OPERATING SYSTEMS) ++++
+
+WARNING: This feature depends on BIOS functionality which is
+apparently broken in a very large number of BIOSes.  Therefore, this
+may not work on any particular system.  No workaround is possible; if
+you find that it doesn't work please complain to your vendor and
+indicate that "BIOS INT 13h AX=4C00h fails."
+
+To boot DOS, or other real-mode operating systems (protected-mode
+operating systems may or may not work correctly), using ISOLINUX, you
+need to prepare a disk image (usually a floppy image, but a hard disk
+image can be used on *most* systems) with the relevant operating
+system.  This file should be included on the CD-ROM in the /isolinux
+directory, and have a .img extension.  The ".img" extension does not
+have to be specified on the command line, but has to be explicitly
+specified if used in a "kernel" statement in isolinux.cfg.
+
+For a floppy image, the size of the image should be exactly one of the
+following:
+
+	1,228,800 bytes		- For a 1200K floppy image
+	1,474,560 bytes		- For a 1440K floppy image
+	2,949,120 bytes		- For a 2880K floppy image
+
+Any other size is assumed to be a hard disk image.  In order to work
+on as many systems as possible, a hard disk image should have exactly
+one partition, marked active, that covers the entire size of the disk
+image file.  Even so, hard disk images are not supported on all
+BIOSes.

+
+Keyboard translation
+--------------------
+
+The PC keyboard emits so-called scan codes, which are basically key
+numbers. The BIOS then translates those scan codes to the character codes
+of the characters printed on the key-caps. By default, the BIOS normally
+assumes that the keyboard has a US layout. Once an operating system is
+loaded, this operating system can use a different mapping.
+
+At boot time, LILO only has access to the basic services provided by the
+BIOS and therefore receives the character codes for an US keyboard. It
+provides a simple mechanism to re-map the character codes to what is
+appropriate for the actual layout.*
+
+  *  The current mechanism isn't perfect, because it sits on top of the
+    scan code to character code translation performed by the BIOS. This
+    means that key combinations that don't produce any useful character on
+    the US keyboard will be ignored by LILO. The advantage of this approach
+    is its simplicity.
+
+
+Compiling keyboard translation tables
+- - - - - - - - - - - - - - - - - - -
+
+LILO obtains layout information from the keyboard translation tables Linux
+uses for the text console. They are usually stored in
+/usr/lib/kbd/keytables. LILO comes with a program keytab-lilo.pl that reads
+those tables and generates a table suitable for use by the map installer.
+keytab-lilo.pl invokes the program loadkeys to print the tables in a format
+that is easy to parse.*
+
+  *  On some systems, only root can execute loadkeys. It is then necessary
+    to run keytab-lilo.pl as root too.
+
+keytab-lilo.pl is used as follows:
+
+  keytab-lilo.pl [ -p <old_code>=<new_code> ] ...
+    [<path>]<default_layout>[.<extension>] ]
+     [<path>]<kbd_layout>[.<extension>] ]
+
+   -p <old_code>=<new_code>
+     Specifies corrections ("patches") to the mapping obtained from the
+    translation table files. E.g. if pressing the upper case "A" should
+    yield an at sign, -p 65=64 would be used. The  -p  option can be
+    repeated any number of times. The codes can also be given as
+    hexadecimal or as octal numbers if they are prefixed with 0x or 0,
+    respectively.
+  <path>  The directory in which the file resides. The default path is
+    /usr/lib/kbd/keytables.
+  <extension>  Usually the trailing .map, which is automatically added if
+    the file name doesn't contain dots.
+  <default_layout>  Is the layout which specifies the translation by the
+    BIOS. If none is specified, us is assumed.
+  <kbd_layout>  Is the actual layout of the keyboard.
+
+keytab-lilo.pl writes the resulting translation table as a binary string to
+standard output. Such tables can be stored anywhere with any name, but the
+suggested naming convention is /boot/<kbd>.ktl ("Keyboard Table for Lilo"),
+where <kbd> is the name of the keyboard layout.
+
+Example:
+
+keytab-lilo.pl de >/boot/de.ktl

+mboot.c32
+---------
+
+mboot.c32 is a 32-bit comboot module that allows Syslinux and its
+variants to load and boot kernels that use the Multiboot standard
+(e.g. the Xen virtual machine monitor, and the Fiasco and GNU Mach
+microkernels).
+
+To load a multiboot kernel and modules in Syslinux, put mboot.c32 (from
+com32/modules) in the boot directory, and load it as the "kernel" in the
+configuration file.  The command-line to pass to mboot.c32 is the kernel
+command-line, followed by all the module command lines, separated with
+'---'.  For example, to load a Xen VMM, xenlinux and an initrd:
+
+DEFAULT mboot.c32 xen.gz dom0_mem=15000 nosmp noacpi --- linux.gz console=tty0 root=/dev/hda1 --- initrd.img
+
+or, as a choice in a menu:
+
+LABEL Xen
+  KERNEL mboot.c32
+  APPEND xen.gz dom0_mem=15000 nosmp noacpi --- linux.gz console=tty0 root=/dev/hda1 --- initrd.img
+
+mboot.c32 requires version 2.12 or later of Syslinux.

+[This documentation is rather crufty at the moment.]
+
+MEMDISK is meant to allow booting legacy operating systems via PXE,
+and as a workaround for BIOSes where ISOLINUX image support doesn't
+work.
+
+MEMDISK simulates a disk by claiming a chunk of high memory for the
+disk and a (very small - 2K typical) chunk of low (DOS) memory for the
+driver itself, then hooking the INT 13h (disk driver) and INT 15h
+(memory query) BIOS interrupts.
+
+MEMDISK allows for an OS to detect the MEMDISK instance.  (See the
+"Additional technical information" section below.)
+
+To use it, type on the Syslinux command line:
+
+memdisk initrd=diskimg.img
+
+... where diskimg.img is the disk image you want to boot from.
+
+[Obviously, the memdisk binary as well as your disk image file need to
+be present in the boot image directory.]
+
+... or add to your syslinux.cfg/pxelinux.cfg/isolinux.cfg something like:
+
+label dos
+    kernel memdisk
+    append initrd=dosboot.img
+
+Note the following:
+
+a) The disk image can be uncompressed or compressed with gzip or zip.
+
+b) If the disk image is less than 4,194,304 bytes (4096K, 4 MB) it is
+   assumed to be a floppy image and MEMDISK will try to guess its
+   geometry based on the size of the file.  MEMDISK recognizes all the
+   standard floppy sizes as well as common extended formats:
+
+     163,840 bytes  (160K) c=40 h=1 s=8		5.25" SSSD
+     184,320 bytes  (180K) c=40 h=1 s=9		5.25" SSSD

+
+   A small perl script is included in the MEMDISK directory which can
+   determine the geometry that MEMDISK would select for other sizes;
+   in general MEMDISK will correctly detect most physical extended
+   formats used, with 80 cylinders or slightly more.
+
+   If the image is 4 MB or larger, it is assumed to be a hard disk
+   image, and should typically have an MBR and a partition table.  It
+   may optionally have a DOSEMU geometry header; in which case the
+   header is used to determine the C/H/S geometry of the disk.
+   Otherwise, the geometry is determined by examining the partition
+   table, so the entire image should be partitioned for proper
+   operation (it may be divided between multiple partitions, however.)
+
+   You can also specify the geometry manually with the following command
+   line options:
+
+   c=#		Specify number of cylinders (max 1024[*])
+   h=#		Specify number of heads (max 256[*])
+   s=#		Specify number of sectors (max 63)
+   floppy[=#]	The image is a floppy image[**]
+   harddisk[=#]	The image is a hard disk image[**]
+   iso		The image is an El Torito ISO9660 image (drive 0xE0)
+
+   # represents a decimal number.
+
+    [*] MS-DOS only allows max 255 heads, and only allows 255 cylinders
+        on floppy disks.
+
+   [**] Normally MEMDISK emulates the first floppy or hard disk.  This
+        can be overridden by specifying an index, e.g. floppy=1 will
+        simulate fd1 (B:). This may not work on all operating systems
+        or BIOSes.
+
+c) The disk is normally writable (although, of course, there is
+   nothing backing it up, so it only lasts until reset.)  If you want,
+   you can mimic a write-protected disk by specifying the command line
+   option:
+
+   ro		Disk is readonly
+
+d) MEMDISK normally uses the BIOS "INT 15h mover" API to access high
+   memory.  This is well-behaved with extended memory managers which load
+   later.  Unfortunately it appears that the "DOS boot disk" from
+   WinME/XP *deliberately* crash the system when this API is invoked.
+   The following command-line options tells MEMDISK to enter protected
+   mode directly, whenever possible:
+
+   raw		Use raw access to protected mode memory.
+
+   bigraw	Use raw access to protected mode memory, and leave the
+		CPU in "big real" mode afterwards.
+
+   int		Use plain INT 15h access to protected memory.  This assumes
+   		that anything which hooks INT 15h knows what it is doing.
+
+   safeint	Use INT 15h access to protected memory, but invoke
+		INT 15h the way it was *before* MEMDISK was loaded.
+		This is the default since version 3.73.
+
+e) MEMDISK by default supports EDD/EBIOS on hard disks, but not on
+   floppy disks.  This can be controlled with the options:
+
+   edd		Enable EDD/EBIOS
+   noedd	Disable EDD/EBIOS
+
+f) The following option can be used to pause to view the messages:
+
+   pause	Wait for a keypress right before booting
+
+g) The following option can be used to set the real-mode stack size.
+   The default is 512 bytes, but if there is a failure it might be
+   interesting to set it to something larger:
+
+   stack=size   Set the stack to "size" bytes
+
+h) Some systems without a floppy drive have been known to have
+   problems with floppy images.  To avoid that those problems, first
+   of all make sure you don't have a floppy drive configured on the
+   BIOS screen.  If there is no option to configure that, or that
+   doesn't work, you can use the option:
+
+   nopass	Hide all real drives of the same type (floppy or hard disk)
+   nopassany    Hide all real drives (floppy and hard disk)
+
+
+Some interesting things to note:
+
+If you're using MEMDISK to boot DOS from a CD-ROM (using ISOLINUX),
+you might find the generic El Torito CD-ROM driver by Gary Tong and
+Bart Lagerweij useful.  It is now included with the Syslinux
+distribution, in the dosutil directory.  See the file
+dosutil/eltorito.txt for more information.
+
+Similarly, if you're booting DOS over the network using PXELINUX, you
+can use the "keeppxe" option and use the generic PXE (UNDI) NDIS
+network driver, which is part of the PROBOOT.EXE distribution from
+Intel:
+
+	http://www.intel.com/support/network/adapter/1000/software.htm
+
+
+Additional technical information:
+
+Starting with version 2.08, MEMDISK now supports an installation check
+API.  This works as follows:
+
+	EAX = 454D08xxh ("ME") (08h = parameter query)
+	ECX = 444Dxxxxh ("MD")
+	EDX = 5349xxnnh	("IS") (nn = drive #)
+	EBX = 3F4Bxxxxh ("K?")
+	INT 13h
+
+If drive nn is a MEMDISK, the registers will contain:
+
+	EAX = 4D21xxxxh	("!M")
+	ECX = 4D45xxxxh ("EM")
+	EDX = 4944xxxxh ("DI")
+	EBX = 4B53xxxxh ("SK")
+
+	ES:DI -> MEMDISK info structures
+
+The low parts of EAX/ECX/EDX/EBX have the normal return values for INT
+13h, AH=08h, i.e. information of the disk geometry etc.
+
+See Ralf Brown's interrupt list,
+http://www.cs.cmu.edu/afs/cs.cmu.edu/user/ralf/pub/WWW/files.html or
+http://www.ctyme.com/rbrown.htm, for a detailed description.
+
+The MEMDISK info structure currently contains:
+
+	[ES:DI]		word	Total size of structure (currently 30 bytes)
+	[ES:DI+2]	byte	MEMDISK minor version
+	[ES:DI+3]	byte	MEMDISK major version
+	[ES:DI+4]	dword	Pointer to MEMDISK data in high memory
+	[ES:DI+8]	dword	Size of MEMDISK data in sectors
+	[ES:DI+12]	16:16	Far pointer to command line
+	[ES:DI+16]	16:16	Old INT 13h pointer
+	[ES:DI+20]	16:16	Old INT 15h pointer
+	[ES:DI+24]	word	Amount of DOS memory before MEMDISK loaded
+	[ES:DI+26]	byte	Boot loader ID
+	[ES:DI+27]	byte	Sector size as a power of 2
+				(If zero, assume 512-byte sectors)
+	[ES:DI+28]	word	If nonzero, offset (vs ES) to installed DPT
+				This pointer+16 contains the original INT 1Eh
+
+Sizes of this structure:
+
+3.71+		30 bytes	Added DPT pointer
+3.00-3.70	27 bytes	Added boot loader ID
+pre-3.00	26 bytes
+
+In addition, the following fields are available at [ES:0]:
+
+	[ES:0]		word	Offset of INT 13h routine (segment == ES)
+	[ES:2]		word	Offset of INT 15h routine (segment == ES)
+
+The program mdiskchk.c in the sample directory is an example on how
+this API can be used.
+
+The following code can be used to "disable" MEMDISK.  Note that it
+does not free the handler in DOS memory, and that running this from
+DOS will probably crash your machine (DOS doesn't like drives suddenly
+disappearing from underneath.)  This is also not necessarily the best
+method for this.

+MEMDISK supports the Win9x "safe hook" structure for OS detection.
+(See "Safe Master Boot Record INT 13h Hook Routines," available at
+http://www.osronline.com/ddkx/w98ddk/storage_5l6g.htm as of
+December 7th, 2009.)  An OS driver can take a look at the INTerrupt table
+and try to walk along the chain of those hooks that implement the "safe hook"
+structure.  For each hook discovered, a vendor can be identified and the OS
+driver can take appropriate action.  The OS driver can mark the "flags" field
+of the "safe hook" to indicate that the driver has reviewed it already.  This
+prevents accidental re-detection, for example.
+
+MEMDISK adds one additional extension field to the "safe hook" structure, a
+pointer to a special MEMDISK structure called the "mBFT."  The mBFT is the
+"MEMDISK Boot Firmware Table" (akin to the iSCSI iBFT and the AoE aBFT).  An
+OS driver looking at MEMDISK's "safe hook" should know that this field will
+be present based on the fact that MEMDISK is the vendor identifier.
+
+The mBFT is little more than an ACPI table to prefix MEMDISK's traditional
+MEMDISK info structure (the "MDI").  The ACPI table's details are:
+
+  OEM ID. . . .: MEMDSK
+  OEM Table ID : Syslinux
+
+There is a 1-byte checksum field which covers the length of the mBFT all
+the way through to the end of the MEMDISK info structure.
+
+There is also a physical pointer to the "safe hook" structure associated
+with the MEMDISK instance.  An OS driver might use the following logic:
+
+  1. Walk INT 13h "safe hook" chain as far as possible, marking hooks as
+     having been reviewed.  For MEMDISK hooks, the driver then follows the
+     pointer to the mBFT and gathers the RAM disk details from the included
+     MDI.
+  2. The OS driver scans low memory for valid mBFTs.  MEMDISK instances that
+     have been "disconnected" from the INT 13h "safe hook" chain can be thus
+     discovered.  Looking at their associated "safe hook" structure will
+     reveal if they were indeed reviewed by the previous stage.

+There are two menu systems included with Syslinux, the advanced menu
+system, and the simple menu system.
+
+
++++ THE ADVANCED MENU SYSTEM +++
+
+The advanced menu system, written by Murali Krishnan Ganapathy, is
+located in the menu/ subdirectly.  It allows the user to create
+hierarchial submenus, dynamic options, checkboxes, and just about
+anything you want.  It requires that the menu is compiled from a
+simple C file, see menu/simple.c and menu/complex.c for examples.
+
+The advanced menu system doesn't support serial console at this time.
+
+See menu/README for more information.
+
+
++++ THE SIMPLE MENU SYSTEM +++
+
+The simple menu system is a single module located at
+com32/modules/vesamenu.c32 (graphical) or com32/modules/menu.c32 (text
+mode only).  It uses the same configuration file as the regular
+Syslinux command line, and displays all the LABEL statements.
+
+To use the menu system, simply make sure [vesa]menu.c32 is in the
+appropriate location for your boot medium (the same directory as the
+configuration file for SYSLINUX, EXTLINUX and ISOLINUX, and the same
+directory as pxelinux.0 for PXELINUX), and put the following options
+in your configuration file:
+
+UI menu.c32
+
+
+There are a few menu additions to the configuration file, all starting
+with the keywords MENU or TEXT; like the rest of the Syslinux config
+file language, it is case insensitive:
+
+
+MENU TITLE title
+
+	Give the menu a title.  The title is presented at the top of
+	the menu.
+
+
+MENU HIDDEN
+
+	Do not display the actual menu unless the user presses a key.
+	All that is displayed is a timeout message.
+
+
+MENU CLEAR
+
+	Clear the screen when exiting the menu, instead of leaving the
+	menu displayed.  For vesamenu, this means the graphical
+	background is still displayed without the menu itself for as
+	long as the screen remains in graphics mode.
+
+
+MENU SHIFTKEY
+
+	Exit the menu system immediately unless either the Shift or Alt
+	key is pressed, or Caps Lock or Scroll Lock is set.
+
+
+MENU SEPARATOR
+
+	Insert an empty line in the menu.
+
+
+MENU LABEL label
+
+	(Only valid after a LABEL statement.)
+	Changes the label displayed for a specific entry.  This allows
+	you to have a label that isn't suitable for the command line,
+	for example:
+
+	# Soft Cap Linux
+	LABEL softcap
+		MENU LABEL Soft Cap ^Linux 9.6.36
+		KERNEL softcap-9.6.36.bzi
+		APPEND whatever
+
+	# A very dense operating system
+	LABEL brick
+		MENU LABEL ^Windows CE/ME/NT
+		KERNEL chain.c32
+		APPEND hd0 2
+
+	The ^ symbol in a MENU LABEL statement defines a hotkey.
+	The hotkey will be highlighted in the menu and will move the
+	menu cursor immediately to that entry.
+
+	Reusing hotkeys is disallowed, subsequent entries will not be
+	highlighted, and will not work.
+
+	Keep in mind that the LABELs, not MENU LABELs, must be unique,
+	or odd things will happen to the command-line.
+
+
+MENU INDENT count
+
+	(Only valid after a LABEL statement.)
+	Will add "count" spaces in front of the displayed menu entry.
+
+
+MENU DISABLE
+
+	(Only valid after a LABEL statement.)
+	Makes the entry unselectable.  This allows you to make a
+	section in your menu with different options below it.
+	for example:
+
+	# Entries for network boots
+	LABEL -
+		MENU LABEL Network:
+		MENU DISABLE
+
+	# Soft Cap Linux
+	LABEL softcap
+		MENU LABEL Soft Cap ^Linux 9.6.36
+		MENU INDENT 1
+		KERNEL softcap-9.6.36.bzi
+		APPEND whatever
+
+	# Dos 6.22
+	LABEL dos
+		MENU LABEL ^Dos 6.22
+		MENU INDENT 1
+		KERNEL memdisk
+		APPEND initrd=dos622.imz
+
+	# Separator
+	MENU SEPARATOR
+
+	# Entries for local boots
+	LABEL -
+		MENU LABEL Local:
+		MENU DISABLE
+
+	# Windows 2000
+	LABEL w2k
+		MENU LABEL ^Windows 2000
+		MENU INDENT 1
+		KERNEL chain.c32
+		APPEND hd0 1
+
+	# Windows XP
+	LABEL xp
+		MENU LABEL Windows ^XP
+		MENU INDENT 1
+		KERNEL chain.c32
+		APPEND hd0 2
+
+MENU HIDE
+
+	(Only valid after a LABEL statement.)
+	Suppresses a particular LABEL entry from the menu.
+
+
+MENU DEFAULT
+
+	(Only valid after a LABEL statement.)
+
+	Indicates that this entry should be the default for this
+	particular submenu.  See also the DEFAULT directive below.
+
+
+TEXT HELP
+Help text ...
+... which can span multiple lines
+ENDTEXT
+
+	(Only valid after a LABEL statement.)
+
+	Specifies a help text that should be displayed when a particular
+	selection is highlighted.
+
+
+MENU PASSWD passwd
+
+	(Only valid after a LABEL statement.)
+
+	Sets a password on this menu entry.  "passwd" can be either a
+	cleartext password or a password encrypted with one of the
+	following algorithms:
+
+	MD5		(Signature: $1$)
+	SHA-1		(Signature: $4$)
+	SHA-2-256	(Signature: $5$)
+	SHA-2-512	(Signature: $6$)
+
+	Use the included Perl scripts "sha1pass" or "md5pass" to
+	encrypt passwords.  MD5 passwords are compatible with most
+	Unix password file utilities; SHA-1 passwords are probably
+	unique to Syslinux; SHA-2 passwords are compatible with very
+	recent Linux distributions.  Obviously, if you don't encrypt
+	your passwords they will not be very secure at all.
+
+	If you are using passwords, you want to make sure you also use
+	the settings "NOESCAPE 1", "PROMPT 0", and either set
+	"ALLOWOPTIONS 0" or use a master password (see below.)
+
+	If passwd is an empty string, this menu entry can only be
+	unlocked with the master password.
+
+
+MENU MASTER PASSWD passwd
+
+	Sets a master password.  This password can be used to boot any
+	menu entry, and is required for the [Tab] and [Esc] keys to
+	work.
+
+
+MENU RESOLUTION height width
+
+	Requests a specific screen resolution when in graphics mode.
+	The default is "640 480" corresponding to a resolution of
+	640x480 pixels, which all VGA-compatible monitors should be
+	able to display.
+
+	If the selected resolution is unavailable, the text mode menu
+	is displayed instead.
+
+
+MENU BACKGROUND background
+
+	For vesamenu.c32, sets the background image.  The background
+	can either be a color (see MENU COLOR) or the name of an image
+	file, which should be the size of the screen (normally 640x480
+	pixels, but see MENU RESOLUTION) and either in PNG, JPEG or
+	LSS16 format.
+
+
+MENU BEGIN [tagname]
+MENU END
+
+	Begin/end a submenu.  The entries between MENU BEGIN and MENU
+	END form a submenu, which is marked with a > mark on the right
+	hand of the screen.  Submenus inherit the properties of their
+	parent menus, but can override them, and can thus have their
+	own backgrounds, master passwords, titles, timeouts, messages
+	and so forth.
+
+
+MENU GOTO tagname
+
+	(Only valid after a LABEL statement.)
+
+	This label will transfer to the named submenu instead of
+	booting anything.  To transfer to the top-level menu, specify
+	"menu goto .top".
+
+
+MENU EXIT [tagname]
+
+	(Only valid after a label statement inside MENU BEGIN ...
+	MENU END)
+
+	Exit to the next higher menu, or, if tagname is specified, to
+	the named menu.
+
+
+MENU QUIT
+
+	(Only valid after a LABEL statement.)
+
+	This label quits the menu system.
+
+	WARNING: if MENU MASTER PASSWD or ALLOWOPTIONS 0 is set, this
+	will still allow exiting to the CLI; however, a separate MENU
+	PASSWD can of course be set for this label.
+
+
+MENU START
+
+	(Only valid inside MENU BEGIN ... MENU END)
+
+	Indicates that the menu system should start at the menu being
+	defined instead of at the top-level menu.  See also the
+	DEFAULT directive below.
+
+
+DEFAULT label
+
+	Set the global default.  If "label" points into a submenu,
+	that menu becomes the start menu; in other words, this
+	directive has the same effect as both MENU DEFAULT and MENU
+	START.
+
+	For backwards compatibility with earlier versions of Syslinux,
+	this directive is ignored unless the configuration file also
+	contains a UI directive.
+
+	Note: the CLI accepts options after the label, or even a
+	non-label.  The menu system does not support that.
+
+
+MENU SAVE
+MENU NOSAVE
+
+	Remember the last entry selected and make that the default for
+	the next boot.  A password-protected menu entry is *not*
+	saved.  This requires the ADV data storage mechanism, which is
+	currently only implemented for EXTLINUX, although the other
+	Syslinux derivatives will accept the command (and ignore it.)
+
+	NOTE: MENU SAVE stores the LABEL tag of the selected entry;
+	this mechanism therefore relies on LABEL tags being unique.
+	On the other hand, it handles changes in the configuration
+	file gracefully.
+
+	NOTE: In software RAID-1 setups MENU SAVE only stores the
+	default label on the actual boot disk.  This may lead to
+	inconsistent reads from the array, or unexpectedly change the
+	default label after array resynchronization or disk failure.
+
+	The MENU SAVE information can be fully cleared with
+	"extlinux --reset-adv <bootdir>".
+
+	A MENU SAVE or MENU NOSAVE at the top of a (sub)menu affects
+	all entries underneath that (sub)menu except those that in
+	turn have MENU SAVE or MENU NOSAVE declared.  This can be used
+	to only save certain entires when selected.
+
+
+INCLUDE filename [tagname]
+MENU INCLUDE filename [tagname]
+
+	Include the contents of the configuration file filename at
+	this point.
+
+	In the case of MENU INCLUDE, the included data is only seen by
+	the menu system; the core syslinux code does not parse this
+	command, so any labels defined in it are unavailable.
+
+	If a tagname is included, the whole file is considered to have
+	been bracketed with a MENU BEGIN tagname ... MENU END pair,
+	and will therefore show up as a submenu.
+
+
+MENU AUTOBOOT message
+
+	Replaces the message "Automatic boot in # second{,s}...".  The
+	symbol # is replaced with the number of seconds remaining.
+	The syntax "{singular,[dual,]plural}" can be used to conjugate
+	appropriately.
+
+
+MENU TABMSG message
+
+	Replaces the message "Press [Tab] to edit options".
+
+
+MENU NOTABMSG message
+
+	Takes the place of the TABMSG message if option editing is
+	disabled.  Defaults to blank.
+
+
+MENU PASSPROMPT message
+
+	Replaces the message "Password required".
+
+
+MENU COLOR element ansi foreground background shadow
+
+	Sets the color of element "element" to the specified color
+	sequence:
+
+	screen          Rest of the screen
+	border          Border area
+	title           Title bar
+	unsel           Unselected menu item
+	hotkey          Unselected hotkey
+	sel             Selection bar
+	hotsel          Selected hotkey
+	disabled	Disabled menu item
+	scrollbar       Scroll bar
+	tabmsg          Press [Tab] message
+	cmdmark         Command line marker
+	cmdline         Command line
+	pwdborder       Password box border
+	pwdheader       Password box header
+	pwdentry        Password box contents
+	timeout_msg     Timeout message
+	timeout         Timeout counter
+	help		Help text
+	msgXX		Message (F-key) file attribute XX
+
+	... where XX is two hexadecimal digits (the "plain text" is 07).
+
+	"ansi" is a sequence of semicolon-separated ECMA-48 Set
+	Graphics Rendition (<ESC>[m) sequences:
+
+	0     reset all attributes to their defaults
+	1     set bold
+	4     set underscore (simulated with color on a color display)
+	5     set blink
+	7     set reverse video
+	22    set normal intensity
+	24    underline off
+	25    blink off
+	27    reverse video off
+	30    set black foreground
+	31    set red foreground
+	32    set green foreground
+	33    set brown foreground
+	34    set blue foreground
+	35    set magenta foreground
+	36    set cyan foreground
+	37    set white foreground
+	38    set underscore on, set default foreground color
+	39    set underscore off, set default foreground color
+	40    set black background
+	41    set red background
+	42    set green background
+	43    set brown background
+	44    set blue background
+	45    set magenta background
+	46    set cyan background
+	47    set white background
+	49    set default background color
+
+	These are used (a) in text mode, and (b) on the serial
+	console.
+
+	"foreground" and "background" are color codes in #AARRGGBB
+	notation, where AA RR GG BB are hexadecimal digits for alpha
+	(opacity), red, green and blue, respectively.  #00000000
+	represents fully transparent, and #ffffffff represents opaque
+	white.
+
+	"shadow" controls the handling of the graphical console text
+	shadow.  Permitted values are "none" (no shadowing), "std" or
+	"standard" (standard shadowing - foreground pixels are
+	raised), "all" (both background and foreground raised), and
+	"rev" or "reverse" (background pixels are raised.)
+
+	If any field is set to "*" or omitted (at the end of the line)
+	then that field is left unchanged.
+
+
+	The current defaults are:
+
+	menu color screen	37;40      #80ffffff #00000000 std
+	menu color border	30;44      #40000000 #00000000 std

+	menu color msg07	37;40      #90ffffff #00000000 std
+
+
+MENU MSGCOLOR fg_filter bg_filter shadow
+
+	Sets *all* the msgXX colors to a color scheme derived from the
+	fg_filter and bg_filter values.  Background color zero is
+	always treated as transparent.  The default corresponds to:
+
+	menu msgcolor #90ffffff #80ffffff std
+
+	This directive should come before any directive that
+	customizes individual msgXX colors.
+
+
+MENU WIDTH 80
+MENU MARGIN 10
+MENU PASSWORDMARGIN 3
+MENU ROWS 12
+MENU TABMSGROW 18
+MENU CMDLINEROW 18
+MENU ENDROW -1
+MENU PASSWORDROW 11
+MENU TIMEOUTROW 20
+MENU HELPMSGROW 22
+MENU HELPMSGENDROW -1
+MENU HIDDENROW -2
+MENU HSHIFT 0
+MENU VSHIFT 0
+
+	These options control the layout of the menu on the screen.
+	The values above are the defaults.
+
+	A negative value is relative to the calculated length of the
+	screen (25 for text mode, 28 for VESA graphics mode.)
+
+
+F1 textfile [background]
+...
+F12 textfile [background]
+
+	Displays full-screen help (also available at the command line.)
+	The same control code sequences as in the command line
+	interface are supported, although some are ignored.
+
+	Additionally, a optional second argument allows a different
+	background image (see MENU BACKGROUND for supported formats)
+	to be displayed.
+
+
+MENU HELP textfile [background]
+
+	Creates a menu entry which, when selected, displays
+	full-screen help in the same way as the F-key help.
+
+
+The menu system honours the TIMEOUT command; if TIMEOUT is specified
+it will execute the ONTIMEOUT command if one exists, otherwise it will
+pick the default menu option.  WARNING: the timeout action will bypass
+password protection even if one is set for the specified or default
+entry!
+
+Normally, the user can press [Tab] to edit the menu entry, and [Esc]
+to return to the Syslinux command line.  However, if the configuration
+file specifies ALLOWOPTIONS 0, these keys will be disabled, and if
+MENU MASTER PASSWD is set, they require the master password.
+
+The simple menu system supports serial console, using the normal
+SERIAL directive.  However, it can be quite slow over a slow serial
+link; you probably want to set your baudrate to 38400 or higher if
+possible.  It requires a Linux/VT220/ANSI-compatible terminal on the
+other end.
+
+
+	+++ USING AN ALTERNATE CONFIGURATION FILE +++
+
+
+It is also possible to load a secondary configuration file, to get to
+another menu.  To do that, invoke menu.c32 with the name of the
+secondary configuration file.
+
+LABEL othermenu
+	MENU LABEL Another Menu
+	KERNEL menu.c32
+	APPEND othermenu.conf
+
+If you specify more than one file, they will all be read, in the order
+specified.  The dummy filename ~ (tilde) is replaced with the filename
+of the main configuration file.
+
+# The file graphics.conf contains common color and layout commands for
+# all menus.
+LABEL othermenu
+	MENU LABEL Another Menu
+	KERNEL vesamenu.c32
+	APPEND graphics.conf othermenu.conf
+
+# Return to the main menu
+LABEL mainmenu
+	MENU LABEL Return to Main Menu
+	KERNEL vesamenu.c32
+	APPEND graphics.conf ~
+
+See also the MENU INCLUDE directive above.

+
+    A bootloader for Linux using the PXE network booting protocol
+
+       Copyright 1994-2008 H. Peter Anvin - All Rights Reserved
+
+This program is provided under the terms of the GNU General Public
+License, version 2 or, at your option, any later version.  There is no

+----------------------------------------------------------------------
+
+PXELINUX is a Syslinux derivative, for booting Linux off a network
+server, using a network ROM conforming to the Intel PXE (Pre-Execution
+Environment) specification.  PXELINUX is *not* a program that is
+intended to be flashed or burned into a PROM on the network card; if
+you want that, check out Etherboot (http://www.etherboot.org/).
+Etherboot 5.4 or later can also be used to create a PXE-compliant boot
+PROM for many network cards.
+
+
+    ++++ HOW TO CONFIGURE PXELINUX ++++
+
+PXELINUX operates in many ways like SYSLINUX.  If you are not familiar
+with SYSLINUX, read syslinux.txt first, since this documentation only
+explains the differences.
+
+On the TFTP server, create the directory "/tftpboot", and copy the
+following files to it:
+
+	pxelinux.0		- from the Syslinux distribution
+
+	any kernel or initrd images you want to boot
+
+Finally, create the directory "/tftpboot/pxelinux.cfg".  The
+configuration file (equivalent of syslinux.cfg -- see syslinux.txt for
+the options here) will live in this directory.  Because more than one
+system may be booted from the same server, the configuration file name
+depends on the IP address of the booting machine.  PXELINUX will
+search for its config file on the boot server in the following way:
+
+  First, it will search for the config file using the client UUID, if
+  one is provided by the PXE stack (note, some BIOSes don't have a
+  valid UUID, and you might end up with something like all 1's.)  This is
+  in the standard UUID format using lower case hexadecimal digits, e.g.
+  b8945908-d6a6-41a9-611d-74a6ab80b83d.
+
+  Next, it will search for the config file using the hardware type
+  (using its ARP type code) and address, all in lower case hexadecimal
+  with dash separators; for example, for an Ethernet (ARP type 1)
+  with address 88:99:AA:BB:CC:DD it would search for the filename
+  01-88-99-aa-bb-cc-dd.
+
+  Next, it will search for the config file using its own IP address
+  in upper case hexadecimal, e.g. 192.0.2.91 -> C000025B
+  (you can use the included progam "gethostip" to compute the
+  hexadecimal IP address for any host.)
+
+  If that file is not found, it will remove one hex digit and try
+  again.  Ultimately, it will try looking for a file named "default"
+  (in lower case).
+
+  As an example, if the boot file name is /mybootdir/pxelinux.0, the
+  UUID is b8945908-d6a6-41a9-611d-74a6ab80b83d, the Ethernet MAC
+  address is 88:99:AA:BB:CC:DD and the IP address 192.0.2.91, it will
+  try:
+
+	/mybootdir/pxelinux.cfg/b8945908-d6a6-41a9-611d-74a6ab80b83d
+	/mybootdir/pxelinux.cfg/01-88-99-aa-bb-cc-dd
+	/mybootdir/pxelinux.cfg/C000025B
+	/mybootdir/pxelinux.cfg/C000025
+	/mybootdir/pxelinux.cfg/C00002
+	/mybootdir/pxelinux.cfg/C0000
+	/mybootdir/pxelinux.cfg/C000
+	/mybootdir/pxelinux.cfg/C00
+	/mybootdir/pxelinux.cfg/C0
+	/mybootdir/pxelinux.cfg/C
+	/mybootdir/pxelinux.cfg/default
+
+  ... in that order.
+
+Note that all filename references are relative to the directory
+pxelinux.0 lives in.  PXELINUX generally requires that filenames
+(including any relative path) are 127 characters or shorter in length.
+
+Starting in release 3.20, PXELINUX will no longer apply a built-in
+default if it cannot find any configuration file at all; instead it
+will reboot after the timeout interval has expired.  This keeps a
+machine from getting stuck indefinitely due to a boot server failure.
+
+Starting in release 3.50, PXELINUX displays network information at
+the boot prompt pressing <Ctrl-N>.
+
+PXELINUX does not support MTFTP, and I have no plans of doing so, as
+MTFTP is inherently broken for files more than 65535 packets (about
+92 MB) in size.  It is of course possible to use MTFTP for the initial
+boot, if you have such a setup.  MTFTP server setup is beyond the
+scope of this document.
+
+
+    ++++ SETTING UP THE TFTP SERVER ++++
+
+PXELINUX currently requires that the boot server has a TFTP server
+which supports the "tsize" TFTP option (RFC 1784/RFC 2349).  The
+"tftp-hpa" TFTP server, which support options, is available at:
+
+	http://www.kernel.org/pub/software/network/tftp/
+	ftp://www.kernel.org/pub/software/network/tftp/
+
+... and on any kernel.org mirror (see http://www.kernel.org/mirrors/).
+
+Another TFTP server which supports this is atftp by Jean-Pierre
+Lefebvre:
+
+	ftp://ftp.mamalinux.com/pub/atftp/
+
+If your boot server is running Windows (and you can't fix that), try
+tftpd32 by Philippe Jounin (you need version 2.11 or later; previous
+versions had a bug which made it incompatible with PXELINUX):
+
+	http://tftpd32.jounin.net/
+
+
+    ++++ SETTING UP THE DHCP SERVER ++++
+
+The PXE protocol uses a very complex set of extensions to DHCP or
+BOOTP.  However, most PXE implementations -- this includes all Intel
+ones version 0.99n and later -- seem to be able to boot in a
+"conventional" DHCP/TFTP configuration.  Assuming you don't have to
+support any very old or otherwise severely broken clients, this is
+probably the best configuration unless you already have a PXE boot
+server on your network.
+
+A sample DHCP setup, using the "conventional TFTP" configuration,
+would look something like the following, using ISC dhcp 2.0 dhcpd.conf
+syntax:
+
+        allow booting;
+        allow bootp;
+
+	# Standard configuration directives...
+
+        option domain-name "<domain name>";
+        option subnet-mask <subnet mask>;
+        option broadcast-address <broadcast address>;
+        option domain-name-servers <dns servers>;
+        option routers <default router>;
+
+	# Group the PXE bootable hosts together
+	group {
+		# PXE-specific configuration directives...
+		next-server <TFTP server address>;
+		filename "/tftpboot/pxelinux.0";
+
+		# You need an entry like this for every host
+		# unless you're using dynamic addresses
+	        host <hostname> {
+		        hardware ethernet <ethernet address>;
+			fixed-address <hostname>;
+		}
+	}
+
+Note that if your particular TFTP daemon runs under chroot (tftp-hpa
+will do this if you specify the -s (secure) option; this is highly
+recommended), you almost certainly should not include the /tftpboot
+prefix in the filename statement.
+
+If this does not work for your configuration, you probably should set
+up a "PXE boot server" on port 4011 of your TFTP server; a free PXE
+boot server is available at:
+
+	http://www.kano.org.uk/projects/pxe/
+
+With such a boot server defined, your DHCP configuration should look
+the same except for an "option dhcp-class-identifier" ("option
+vendor-class-identifier" if you are using DHCP 3.0):
+
+        allow booting;
+        allow bootp;
+
+	# Standard configuration directives...
+
+        option domain-name "<domain name>";
+        option subnet-mask <subnet mask>;
+        option broadcast-address <broadcast address>;
+        option domain-name-servers <dns servers>;
+        option routers <default router>;
+
+	# Group the PXE bootable hosts together
+	group {
+		# PXE-specific configuration directives...
+	        option dhcp-class-identifier "PXEClient";
+		next-server <pxe boot server address>;
+
+		# You need an entry like this for every host
+		# unless you're using dynamic addresses
+	        host <hostname> {
+		        hardware ethernet <ethernet address>;
+			fixed-address <hostname>;
+		}
+	}
+
+Here, the boot file name is obtained from the PXE server.
+
+If the "conventional TFTP" configuration doesn't work on your clients,
+and setting up a PXE boot server is not an option, you can attempt the
+following configuration.  It has been known to boot some
+configurations correctly; however, there are no guarantees:
+
+        allow booting;
+        allow bootp;
+
+	# Standard configuration directives...
+
+        option domain-name "<domain name>";
+        option subnet-mask <subnet mask>;
+        option broadcast-address <broadcast address>;
+        option domain-name-servers <dns servers>;
+        option routers <default router>;
+
+	# Group the PXE bootable hosts together
+	group {
+		# PXE-specific configuration directives...
+	        option dhcp-class-identifier "PXEClient";
+		option vendor-encapsulated-options 09:0f:80:00:0c:4e:65:74:77:6f:72:6b:20:62:6f:6f:74:0a:07:00:50:72:6f:6d:70:74:06:01:02:08:03:80:00:00:47:04:80:00:00:00:ff;
+		next-server <TFTP server>;
+		filename "/tftpboot/pxelinux.0";
+
+		# You need an entry like this for every host
+		# unless you're using dynamic addresses
+	        host <hostname> {
+		        hardware ethernet <ethernet address>;
+			fixed-address <hostname>;
+		}
+	}
+
+Note that this *will not* boot some clients that *will* boot with the
+"conventional TFTP" configuration; Intel Boot Client 3.0 and later are
+known to fall into this category.
+
+
+    ++++ SPECIAL DHCP OPTIONS ++++
+
+PXELINUX (starting with version 1.62) supports the following
+nonstandard DHCP options, which depending on your DHCP server you may
+be able to use to customize the specific behaviour of PXELINUX.  See
+RFC 5071 for some additional information about these options.
+
+Option 208	pxelinux.magic
+	- Earlier versions of PXELINUX required this to be set to
+	  F1:00:74:7E (241.0.116.126) for PXELINUX to
+	  recognize any special DHCP options whatsoever.  As of
+	  PXELINUX 3.55, this option is deprecated and is no longer
+	  required.
+
+Option 209	pxelinux.configfile
+	- Specifies the PXELINUX configuration file name.
+
+Option 210	pxelinux.pathprefix
+	- Specifies the PXELINUX common path prefix, instead of
+	  deriving it from the boot file name.  This almost certainly
+	  needs to end in whatever character the TFTP server OS uses
+	  as a pathname separator, e.g. slash (/) for Unix.
+
+Option 211	pxelinux.reboottime
+	- Specifies, in seconds, the time to wait before reboot in the
+	  event of TFTP failure.  0 means wait "forever" (in reality,
+	  it waits approximately 136 years.)
+
+ISC dhcp 3.0 supports a rather nice syntax for specifying custom
+options; you can use the following syntax in dhcpd.conf if you are
+running this version of dhcpd:
+
+	option space pxelinux;
+	option pxelinux.magic      code 208 = string;
+	option pxelinux.configfile code 209 = text;
+	option pxelinux.pathprefix code 210 = text;
+	option pxelinux.reboottime code 211 = unsigned integer 32;
+
+    NOTE: In earlier versions of PXELINUX, this would only work as a
+    "site-option-space".  Since PXELINUX 2.07, this will work both as a
+    "site-option-space" (unencapsulated) and as a "vendor-option-space"
+    (type 43 encapsulated.)  This may avoid messing with the
+    dhcp-parameter-request-list, as detailed below.
+
+Then, inside your PXELINUX-booting group or class (whereever you have
+the PXELINUX-related options, such as the filename option), you can
+add, for example:
+
+	# Always include the following lines for all PXELINUX clients
+	site-option-space "pxelinux";
+	option pxelinux.magic f1:00:74:7e;
+	if exists dhcp-parameter-request-list {
+		# Always send the PXELINUX options (specified in hexadecimal)
+		option dhcp-parameter-request-list = concat(option dhcp-parameter-request-list,d0,d1,d2,d3);
+	}
+	# These lines should be customized to your setup
+	option pxelinux.configfile "configs/common";
+	option pxelinux.pathprefix "/tftpboot/pxelinux/files/";
+	option pxelinux.reboottime 30;
+	filename "/tftpboot/pxelinux/pxelinux.bin";
+
+Note that the configfile is relative to the pathprefix: this will look
+for a config file called /tftpboot/pxelinux/files/configs/common on
+the TFTP server.
+
+The "option dhcp-parameter-request-list" statement forces the DHCP
+server to send the PXELINUX-specific options, even though they are not
+explicitly requested.  Since the DHCP request is done before PXELINUX
+is loaded, the PXE client won't know to request them.
+
+Using ISC dhcp 3.0 you can create a lot of these strings on the fly.
+For example, to use the hexadecimal form of the hardware address as
+the configuration file name, you could do something like:
+
+	site-option-space "pxelinux";
+	option pxelinux.magic f1:00:74:7e;
+	if exists dhcp-parameter-request-list {
+		# Always send the PXELINUX options (specified in hexadecimal)
+		option dhcp-parameter-request-list = concat(option dhcp-parameter-request-list,d0,d1,d2,d3);
+	}
+	option pxelinux.configfile =
+		concat("pxelinux.cfg/", binary-to-ascii(16, 8, ":", hardware));
+	filename "/tftpboot/pxelinux.bin";
+
+If you used this from a client whose Ethernet address was
+58:FA:84:CF:55:0E, this would look for a configuration file named
+"/tftpboot/pxelinux.cfg/1:58:fa:84:cf:55:e".
+
+
+    ++++ ALTERNATE TFTP SERVERS ++++
+
+PXELINUX supports the following special pathname conventions:
+
+::filename
+
+	Suppresses the common filename prefix, i.e. passes the string
+	"filename" unmodified to the server.
+
+IP address::filename		(e.g. 192.0.2.1::filename)
+
+	Suppresses the common filename prefix, *and* sends a request
+	to an alternate TFTP server.  Instead of an IP address, a
+	DNS name can be used.  It will be assumed to be fully
+	qualified if it contains dots; otherwise the local domain as
+	reported by the DHCP server (option 15) will be added.
+
+:: was chosen because it is unlikely to conflict with operating system
+usage.  However, if you happen to have an environment for which the
+special treatment of :: is a problem, please contact the Syslinux
+mailing list.
+
+
+    ++++ SOME NOTES ++++
+
+If the boot fails, PXELINUX (unlike SYSLINUX) will not wait forever;
+rather, if it has not received any input for approximately five
+minutes after displaying an error message, it will reset the machine.
+This allows an unattended machine to recover in case it had bad enough
+luck of trying to boot at the same time the TFTP server goes down.
+
+Lots of PXE stacks, especially old ones, have various problems of
+varying degrees of severity.  Please see:
+
+	http://syslinux.zytor.com/hardware.php
+
+... for a list of currently known hardware problems, with workarounds
+if known.
+
+
+    ++++ KEEPING THE PXE STACK AROUND ++++
+
+Normally, PXELINUX will unload the PXE and UNDI stacks before invoking
+the kernel.  In special circumstances (for example, when using MEMDISK
+to boot an operating system with an UNDI network driver) it might be
+desirable to keep the PXE stack in memory.  If the option "keeppxe"
+is given on the kernel command line, PXELINUX will keep the PXE and
+UNDI stacks in memory.  (If you don't know what this means, you
+probably don't need it.)
+
+
+    ++++ PROBLEMS WITH YOUR PXE STACK ++++
+
+There are a number of extremely broken PXE stacks in the field.  The
+gPXE project (formerly known as Etherboot) provides an open-source PXE
+stack that works with a number of cards, and which can be loaded from
+a CD-ROM, USB key, or floppy if desired.
+
+Information on gPXE is available from:
+
+	http://www.etherboot.org/
+
+... and ready-to-use ROM or disk images from:
+
+	http://www.rom-o-matic.net/
+
+Some cards, like may systems with the SiS 900, has a PXE stack which
+works just barely well enough to load a single file, but doesn't
+handle the more advanced items required by PXELINUX.  If so, it is
+possible to use the built-in PXE stack to load gPXE, which can then
+load PXELINUX.  See:
+
+	http://www.etherboot.org/wiki/pxechaining
+
+
+    ++++ CURRENTLY KNOWN PROBLEMS ++++
+
+The following problems are known with PXELINUX, so far:
+
++ The error recovery routine doesn't work quite right.  For right now,
+  it just does a hard reset - seems good enough.
++ We should probably call the UDP receive function in the keyboard
+  entry loop, so that we answer ARP requests.
++ Boot sectors/disk images are not supported yet.
+
+If you have additional problems, please contact the Syslinux mailing
+list (see syslinux.txt for the address.)

+RFC 5071                    PXELINUX Options               December 2007
+
+
+1.  Introduction
+
+   PXE, the Preboot eXecution Environment, is a first-stage network
+   bootstrap agent.  PXE is loaded out of firmware on the client host,
+   and performs DHCP [3] queries to obtain an IP address.
+
+   Once on the network, it loads a second-stage bootstrap agent as
+   configured by DHCP header and option contents.
+
+   PXELINUX is one such second-stage bootstrap agent.  Once PXE has
+   passed execution to it, PXELINUX seeks its configuration from a cache
+   of DHCP options supplied to the PXE first-stage agent, and then takes
+   action based upon those options.
+
+   Most frequently, this implies loading via Trivial File Transfer
+   Protocol (TFTP) [6] one or more images that are decompressed into
+   memory, then executed to pass execution to the final Host Operating
+   System.
+
+   PXELINUX uses DHCP options 208-211 to govern parts of this bootstrap
+   process, but these options are not requested by the PXE DHCP client
+   at the time it acquires its lease.  At that time, the PXE bootloader
+   has no knowledge that PXELINUX is going to be in use, and even so,
+   would have no way to know what option(s) PXELINUX might digest.
+   Local installations that serve this PXELINUX image to its clients
+   must also configure their DHCP servers to provide these options even
+   though they are not on the DHCP Parameter Request List [4].
+
+   These options are:
+
+   o  "MAGIC" - 208 - An option whose presence and content verifies to
+      the PXELINUX bootloader that the options numbered 209-211 are for
+      the purpose as described herein.
+
+   o  "ConfigFile" - 209 - Configures the path/filename component of the
+      configuration file's location, which this bootloader should use to
+      configure itself.
+
+   o  "PathPrefix" - 210 - Configures a value to be prepended to the
+      ConfigFile to discern the directory location of the file.
+
+   o  "RebootTime" - 211 - Configures a timeout after which the
+      bootstrap program will reboot the system (most likely returning it
+      to PXE).
+
+   Historically, these option codes numbering from 208-211 were
+   designated 'Site Local', but after publication of RFC3942 [8], they
+   were made available for allocation as new standard DHCP options.
+
+
+
+Hankins                      Informational                      [Page 3]
+
+RFC 5071                    PXELINUX Options               December 2007
+
+
+   This document marks these codes as assigned.
+
+   This direct assignment of option code values in the option
+   definitions below is unusual as it is not mentioned in DHCP Option
+   Code assignment guidelines [5].  This document's Option Code
+   assignments are done within RFC 3942's provisions for documenting
+   prior use of option codes within the new range (128-223 inclusive).
+
+2.  Terminology
+
+   o  "first-stage bootloader" - Although a given bootloading order may
+      have many stages, such as where a BIOS boots a DOS Boot Disk,
+      which then loads a PXE executable, it is, in this example, only
+      the PXE executable that this document describes as the "first-
+      stage bootloader" -- in essence, this is the first stage of
+      booting at which DHCP is involved.
+
+   o  "second-stage bootloader" - This describes a program loaded by the
+      first-stage bootloader at the behest of the DHCP server.
+
+   o  "bootloader" and "network bootstrap agent" - These are synonyms,
+      excepting that "bootloader" is intentionally vague in that its
+      next form of bootstrapping may not in fact involve network
+      resources.
+
+   The key words "MAY", "MUST", "MUST NOT", "SHOULD", and "SHOULD NOT"
+   in this document are to be interpreted as described in RFC 2119 [2].
+
+3.  MAGIC Option
+
+3.1.  Description
+
+   If this option is provided to the PXE bootloader, then the value is
+   checked by PXELINUX to match the octet string f1:00:74:7e.  If this
+   matches, then PXELINUX bootloaders will also consume options 209-211,
+   as described below.  Otherwise, they are ignored.
+
+   This measure was intended to ensure that, as the 'Site Local' option
+   space is not allocated from a central authority, no conflict would
+   result in a PXELINUX bootloader improperly digesting options intended
+   for another purpose.

+3.2.  Packet Format
+
+   The MAGIC Option format is as follows:
+

+           +--------+--------+--------+--------+--------+--------+
+
+   The code for this option is 208.  The length is always four.
+
+3.3.  Applicability
+
+   This option is absolutely inapplicable to any other purpose.
+
+3.4.  Response to RFC 3942
+
+   The option code 208 will be adopted for this purpose and immediately
+   deprecated.  Future standards action may return this option to an
+   available status should it be necessary.
+
+   A collision of the use of this option is harmless (at least from
+   PXELINUX' point of view) by design: if it does not match the
+   aforementioned magic value, the PXELINUX bootloader will take no
+   special action.
+
+   The PXELINUX project will deprecate the use of this option; future
+   versions of the software will not evaluate its contents.
+
+   It is reasonable to utilize this option code for another purpose, but
+   it is recommended to do this at a later time, given the desire to
+   avoid potential collisions in legacy user bases.
+
+4.  Configuration File Option
+
+4.1.  Description
+
+   Once the PXELINUX executable has been entered from the PXE
+   bootloader, it evaluates this option and loads a file of that name
+   via TFTP.  The contents of this file serve to configure PXELINUX in
+   its next stage of bootloading (specifying boot image names,
+   locations, boot-time flags, text to present the user in menu
+   selections, etc).
+
+   In the absence of this option, the PXELINUX agent will search the
+   TFTP server (as determined by PXE prior to this stage) for a config
+   file of several default names.

+
+4.2.  Packet Format
+
+   The Configuration File Option format is as follows:
+
+              Code    Length    Config-file...
+           +--------+--------+--------+--------+--------+--------+
+           |   209  |    n   |   c1   |   c2   |   ...  |   c(n) |
+           +--------+--------+--------+--------+--------+--------+
+
+   The code for this option is 209.  The Config-file (c1..c(n)) is an
+   NVT-ASCII [1] printable string; it is not terminated by a zero or any
+   other value.
+
+4.3.  Applicability
+
+   Any bootloader, PXE or otherwise, that makes use of a separate
+   configuration file rather than containing all configurations within
+   DHCP options (which may be impossible due to the limited space
+   available for DHCP options) may conceivably make use of this option.
+
+4.4.  Response to RFC 3942
+
+   The code 209 will be adopted for this purpose.
+
+4.5.  Client and Server Behaviour
+
+   The Config File Option MUST be supplied by the DHCP server if it
+   appears on the Parameter Request List, but MUST also be supplied if
+   the server administrator believed it would later be useful to the
+   client (such as because the server is configured to offer a second-
+   stage boot image, which they know will make use of it).  The option
+   MUST NOT be supplied if no value has been configured for it, or if a
+   value of zero length has been configured.
+
+   The DHCP client MUST only cache this option in a location the second-
+   stage bootloader may access.
+
+   The second-stage bootloader MUST, in concert with other DHCP options
+   and fields, use this option's value as a filename to be loaded via
+   TFTP and read for further second-stage-loader-specific configuration
+   parameters.  The format and content of such a file is specific to the
+   second-stage bootloader, and as such, is out of scope of this
+   document.

+
+
+5.  Path Prefix Option
+
+5.1.  Description
+
+   In PXELINUX' case, it is often the case that several different
+   environments would have the same TFTP path prefix, but would have
+   different filenames (for example: hosts' bootloader images and config
+   files may be kept in a directory structure derived from their Media
+   Access Control (MAC) address).  Consequently, it was deemed
+   worthwhile to deliver a TFTP path prefix configuration option, so
+   that these two things could be configured separately in a DHCP Server
+   configuration: the prefix and the possibly host-specific file
+   location.
+
+   The actual filename that PXELINUX requests from its TFTP server is
+   derived by prepending this value to the Config File Option above.
+   Once this config file is loaded and during processing, any TFTP file
+   paths specified within it are similarly processed -- prepending the
+   contents of this option.
+
+5.2.  Packet Format
+
+   The Path Prefix Option format is as follows:
+
+              Code    Length   Path-Prefix...
+           +--------+--------+--------+--------+--------+--------+
+           |   210  |    n   |   p1   |   p2   |   ...  |   p(n) |
+           +--------+--------+--------+--------+--------+--------+
+
+   The code for this option is 210.  The Path Prefix is an NVT-ASCII
+   printable string; it is not terminated by zero or any other value.
+
+5.3.  Applicability
+
+   This option came into existence because server administrators found
+   it useful to configure the prefix and suffix of the config file path
+   separately.  A group of different PXE booting clients may use the
+   same path prefix, but different filenames, or vice versa.
+
+   The 'shortcut' this represents is worthwhile, but it is questionable
+   whether that needs to manifest itself on the protocol wire.
+
+
+

+
+
+   It only becomes interesting from a protocol standpoint if other
+   options are adopted that prefix this value as well -- performing a
+   kind of string compression is highly beneficial to the limited
+   available DHCP option space.
+
+   But it's clearly inapplicable to any current use of, e.g., the
+   FILENAME header contents or the DHCP Boot File Name option (#67).
+   Use of these fields is encoded on firmware of thousands of devices
+   that can't or are not likely to be upgraded.  Altering any behaviour
+   here is likely to cause severe compatibility problems.
+
+   Although compression of the TFTP-loaded configuration file contents
+   is not a compelling factor, contrived configurations using these
+   values may also exist: where each of a large variety of different
+   clients load the same configuration file, with the same contents, but
+   due to a differently configured path prefix actually load different
+   images.  Whether this sort of use is truly needed remains unproven.
+
+5.4.  Response to RFC 3942
+
+   The code 210 will be adopted for this purpose.
+
+5.5.  Client and Server Behaviour
+
+   The Path Prefix option MUST be supplied by the DHCP server if it
+   appears on the Parameter Request List, but MUST also be supplied if
+   the server administrator believed it would later be useful to the
+   client (such as because the server is configured to offer a second-
+   stage boot image that they know will make use of it).  The option
+   MUST NOT be supplied if no value has been configured for it, or if a
+   value of zero length has been configured.
+
+   The DHCP client MUST only cache this option in a location where the
+   second-stage bootloader may access it.
+
+   The second-stage bootloader MUST prepend this option's value, if any,
+   to the contents of the ConfigFile option prior to obtaining the
+   resulting value via TFTP, or the default 'Config File Search Path',
+   which the second-stage bootloader iterates in the absence of a Config
+   File Option.  The client MAY prepend the value to other configuration
+   directives within that file once it has been loaded.  The client MUST
+   NOT prepend this option's value to any other DHCP option contents or
+   field, unless explicitly stated in a document describing that option
+   or field.

+
+
+6.  Reboot Time Option
+
+6.1.  Description
+
+   Should PXELINUX be executed, and then for some reason, be unable to
+   reach its TFTP server to continue bootstrapping, the client will, by
+   default, reboot itself after 300 seconds have passed.  This may be
+   too long, too short, or inappropriate behaviour entirely, depending
+   on the environment.
+
+   By configuring a non-zero value in this option, admins can inform
+   PXELINUX of which specific timeout is desired.  The client will
+   reboot itself if it fails to achieve its configured network resources
+   within the specified number of seconds.
+
+   This reboot will run through the system's normal boot-time execution
+   path, most likely leading it back to PXE and therefore PXELINUX.  So,
+   in the general case, this is akin to returning the client to the DHCP
+   INIT state.
+
+   By configuring zero, the feature is disabled, and instead the client
+   chooses to remove itself from the network and wait indefinitely for
+   operator intervention.
+
+   It should be stressed that this is in no way related to configuring a
+   lease time.  The perceived transition to INIT state is due to client
+   running state -- reinitializing itself -- not due to lease timer
+   activity.  That is, it is not safe to assume that a PXELINUX client
+   will abandon its lease when this timer expires.
+
+6.2.  Packet Format
+
+   The Reboot Time Option format is as follows:
+
+              Code    Length
+           +--------+--------+--------+--------+--------+--------+
+           |   211  |    4   |            Reboot Time            |
+           +--------+--------+--------+--------+--------+--------+
+
+   The code for this option is 211.  The length is always four.  The
+   Reboot Time is a 32-bit (4 byte) integer in network byte order.

+
+
+6.3.  Applicability
+
+   Any network bootstrap program in any sufficiently complex networking
+   environment could conceivably enter into such a similar condition,
+   either due to having its IP address stolen out from under it by a
+   rogue client on the network, by being moved between networks where
+   its PXE-derived DHCP lease is no longer valid, or any similar means.
+
+   It seems desirable for any network bootstrap agent to implement an
+   ultimate timeout for it to start over.
+
+   The client may, for example, get different working configuration
+   parameters from a different DHCP server upon restarting.
+
+6.4.  Response to RFC 3942
+
+   The code 211 will be adopted for this purpose.
+
+6.5.  Client and Server Behaviour
+
+   The Reboot Time Option MUST be supplied by the DHCP server if it
+   appears on the Parameter Request List, but MUST also be supplied if
+   the server administrator believed it would later be useful to the
+   client (such as because the server is configured to offer a second-
+   stage boot image that they know will make use of it).  The option
+   MUST NOT be supplied if no value has been configured for it, or if it
+   contains a value of zero length.
+
+   The DHCP client MUST only cache this option in a location the second-
+   stage bootloader may access.
+
+   If the value of this option is nonzero, the second-stage bootloader
+   MUST schedule a timeout: after a number of seconds equal to this
+   option's value have passed, the second-stage bootloader MUST reboot
+   the system, ultimately returning the path of execution back to the
+   first-stage bootloader.  It MUST NOT reboot the system once the
+   thread of execution has been passed to the host operating system (at
+   which point, this timeout is effectively obviated).
+
+   If the value of this option is zero, the second-stage bootloader MUST
+   NOT schedule such a timeout at all.  Any second-stage bootloader that
+   finds it has encountered excessive timeouts attempting to obtain its
+   host operating system SHOULD disconnect itself from the network to
+   wait for operator intervention, but MAY continue to attempt to
+   acquire the host operating system indefinitely.

+
+
+7.  Specification Conformance
+
+   To conform to this specification, clients and servers MUST implement
+   the Configuration File, Path Prefix, and Reboot Time options as
+   directed.
+
+   The MAGIC option MAY NOT be implemented, as it has been deprecated.
+
+8.  Security Considerations
+
+   PXE and PXELINUX allow any entity acting as a DHCP server to execute
+   arbitrary code upon a system.  At present, no PXE implementation is
+   known to implement authentication mechanisms [7] so that PXE clients
+   can be sure they are receiving configuration information from the
+   correct, authoritative DHCP server.
+
+   The use of TFTP by PXE and PXELINUX also lacks any form of
+   cryptographic signature -- so a 'Man in the Middle' attack may lead
+   to an attacker's code being executed on the client system.  Since
+   this is not an encrypted channel, any of the TFTP loaded data may
+   also be exposed (such as in loading a "RAMDISK" image, which contains
+   /etc/passwd or similar information).
+
+   The use of the Ethernet MAC Address as the client's unique identity
+   may allow an attacker who takes on that identity to gain
+   inappropriate access to a client system's network resources by being
+   given by the DHCP server whatever 'keys' are required, in fact, to be
+   the target system (to boot up as though it were the target).
+
+   Great care should be taken to secure PXE and PXELINUX installations,
+   such as by using IP firewalls, to reduce or eliminate these concerns.
+
+   A nearby attacker might feed a "Reboot Time" option value of 1 second
+   to a mass of unsuspecting clients, to effect a Denial Of Service
+   (DoS) upon the DHCP server, but then again it may just as easily
+   supply these clients with rogue second-stage bootloaders that simply
+   transmit a flood of packets.
+
+   This document in and by itself provides no security, nor does it
+   impact existing DCHP security as described in RFC 2131 [3].
+
+9.  IANA Considerations
+
+   IANA has done the following:
+
+   1.  Moved DHCPv4 Option code 208 from 'Tentatively Assigned' to
+       'Assigned', referencing this document.  IANA has marked this same
+       option code, 208, as Deprecated.

+		       SDI files
+
+
+Syslinux supports SDI files ( *.sdi ).
+
+Features:
+ * Support for gzipped SDI images
+ * When used with gpxelinux.0, images can be downloaded by HTTP or FTP,
+   leading to fastest boot times.
+
+"System Deployment Image" is a file format created by Microsoft and mostly used
+in its products to provide in a single file a boot loader, an OS loader
+(like NTLDR) and a disk or partition image to boot from it without any
+other installed program. This is typically used in a PXE environment to boot
+embedded Windows versions without boot disk support.
+
+The support of SDI images in Syslinux is based on a white
+paper from Saad Syed. You can find the paper here:
+
+http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnxpesp1/html/ram_sdi.asp
+
+SDI support has been only been tested with SDI v1.0 with Windows XP Embedded
+images and may not work with later versions or alternative uses.
+
+
+   ++++ Supported SDI images ++++
+
+To make a SDI image supported by pxelinux/isolinux/syslinux, you need to
+follow the steps below (detailed instructions are in the white paper
+cited above):
+
+You need to install "Windows Embedded Studio" and to run the
+"Remote Boot Service Setup".
+
+1) Create a new SDI file (eg: sdimgr /new xpe.sdi).
+
+2) Before importing your target partition, add the following files
+in the root folder:
+	* ntdetect.com
+	* boot.ini
+	Its content should be:
+		[boot loader]
+		  default=ramdisk(0)\WINDOWS
+		  [operating systems]
+		  ramdisk(0)\WINDOWS="Windows XPE  From RAM" /fastdetect
+(you can customize the name and add options like /debug)
+
+Note: Your partition may be compressed (using compressed NTFS), but these two
+files need to be uncompressed.
+
+3) Import the partition in the SDI file (eg: sdimgr xpe.sdi /readpart:D:).
+The size of the partition must be less than 500 MB.
+
+4) Import the boot program STARTROM.COM
+(eg: sdimgr xpe.sdi /import:BOOT,0,C:\Program Files\Windows Embedded\Remote Boot Service\Downloads\startrom.com)
+
+5) Import the nt loader NTLDR in the SDI file
+(eg: sdimgr xpe.sdi /import:LOAD,0,C:\Program Files\Windows Embedded\Remote Boot Service\Downloads\ntldr)
+
+Note: only the version of NTLDR provided by Remote Boot Service Setup
+and located in this directory has been tested. According to
+"http://skolk.livejournal.com/667.html", "osloader.exe" from retail XP
+can also be used to replace this NTLDR version.
+
+6) Pack the SDI file (eg: sdimgr xpe.sdi /pack)
+
+7) Gzip your image
+If you want to speed the download time, you can gzip the image as it will
+be uncompressed by syslinux during the loading. You can use some programs
+like ntfsclone ("http://www.linux-ntfs.org/doku.php?id=ntfsclone") to
+remove unused blocks from the NTFS filesystem before deploying your image.
+
+8) You are now ready to boot your image.
+Unlike the traditional way of using SDI images (startrom.n12), you don't need
+other files than your SDI image in the tftpboot (for pxelinux), the CD
+(for isolinux), or the hard disk for syslinux.
+
+* You can use the usual options of pxelinux/isolinux/syslinux (config file,
+config path, reboot time...)
+
+For example, a simple configuration with pxelinux:
+/tftpboot/xpe.sdi
+/tftpboot/pxelinux.0
+/tftpboot/pxelinux.cfg/default with the following content:
+
+	DEFAULT 0
+	label 0 [WinXpe]
+		KERNEL sdi.c32
+		APPEND xpe.sdi
+
+
+   ++++ Error messages ++++
+
+* No $SDI signature in file
+        A SDI image should begin by a signature "$SDI", the signature has not
+been found in your file. Perhaps your file is corrupted or has not been created
+correctly. Run sdimgr on it to see if everything is correct.
+
+* No BOOT BLOB in image
+        You have to import a boot program (eg: startrom.com) when you make
+your SDI image (see above). The offset of this program in the SDI file
+is in the SDI header (begining of the file). However, the offset
+found in your SDI file is null.
+You probably forgot to include the boot program. Run the sdimgr program
+and look if you see a line like:
+BOOT 0x00000000.00001000 0x00000000.00005EC2...
+                --------
+                This is the
+                offset and
+                should not
+                be null
+
+* BOOT BLOB is empty
+        See above. The size of your boot program included in the SDI
+is null. You probably imported a corrupted version of startrom.com.
+Run sdimgr and check the size in the following line:
+BOOT 0x00000000.00001000 0x00000000.00005EC2...
+                                    --------
+                                    this is the
+                                    size and
+                                    should not
+                                    be null
+
+* BOOT BLOB extends beyond file
+        You have a BOOT BLOB in your SDI file, but its size is invalid
+because its goes beyond the total image size. Check the tools you used
+to build the image file.
+
+* BOOT BLOB too large for memory
+        Your BOOT BLOB seems correct, however there is not enough memory
+to load it. Increase your RAM or reduce the SDI size. This is a very
+abnormal situation as the BOOT BLOB is usually very small. Your SDI
+file might be corrupted.
+
+* Image too large for memory
+        Your SDI file seems correct, however there is not enough memory
+to load it. Increase your RAM or reduce the SDI size.
+
+* SDI header is corrupted
+        Your SDI file seems correct, but its header contains a checksum
+that is invalid. You most likely have a corrupted SDI file.
+
+
+   ++++ Warning messages ++++
+
+* Warning: unknown SDI version
+You are using a newer version of SDI than the one with which this program
+has been tested. It may not work. Please give feedback and provide your
+SDI version.

+
+	 Copyright 1994-2010 H. Peter Anvin and contributors

+
+----------------------------------------------------------------------
+
+      Syslinux now has a home page at http://syslinux.zytor.com/
+
+----------------------------------------------------------------------
+
+The Syslinux suite contains the following boot loaders
+("derivatives"), for their respective boot media:
+
+	SYSLINUX - MS-DOS/Windows FAT filesystem
+	PXELINUX - PXE network booting
+	ISOLINUX - ISO9660 CD-ROM
+	EXTLINUX - Linux ext2/ext3 filesystem
+
+For historical reasons, some of the sections in this document applies
+to the FAT loader (SYSLINUX) only; see pxelinux.txt, isolinux.txt and
+extlinux.txt for what differs in these versions.  The all-caps term
+"SYSLINUX" generally refers to the FAT loader, whereas "Syslinux"
+refers to the project as a whole.
+
+Help with cleaning up the docs would be greatly appreciated.
+
+
+   ++++ Options ++++
+
+These are the options common to all versions of Syslinux:
+
+	-s	Safe, slow, stupid; uses simpler code that boots better
+	-f	Force installing
+	-r	Raid mode.  If boot fails, tell the BIOS to boot the next
+		device in the boot sequence (usually the next hard disk)
+		instead of stopping with an error message.
+		This is useful for RAID-1 booting.
+
+These are only in the Windows version:
+
+	-m	Mbr; install a bootable MBR sector to the beginning of the
+		drive.
+	-a	Active; marks the partition used active (=bootable)
+
+
+   ++++ CREATING A BOOTABLE LINUX FLOPPY +++
+
+In order to create a bootable Linux floppy using SYSLINUX, prepare a
+normal MS-DOS formatted floppy.  Copy one or more Linux kernel files to
+it, then execute the DOS command:
+
+        syslinux [-sfrma][-d directory] a: [bootsecfile]
+
+(or whichever drive letter is appropriate; the [] meaning optional.)
+
+Use "syslinux.com" (in the dos subdirectory of the distribution) for
+plain DOS (MS-DOS, DR-DOS, PC-DOS, FreeDOS...) or Win9x/ME.
+
+Use "syslinux.exe" (in the win32 subdirectory of the distribution) for
+WinNT/2000/XP.
+
+Under Linux, execute the command:
+
+	syslinux [-sfr][-d directory][-o offset] /dev/fd0
+
+(or, again, whichever device is the correct one.)
+
+This will alter the boot sector on the disk and copy a file named
+LDLINUX.SYS into its root directory (or a subdirectory, if the -d
+option is specified.)
+
+The -s option, if given, will install a "safe, slow and stupid"
+version of SYSLINUX.  This version may work on some very buggy BIOSes
+on which SYSLINUX would otherwise fail.  If you find a machine on
+which the -s option is required to make it boot reliably, please send
+as much info about your machine as you can, and include the failure
+mode.
+
+The -o option is used with a disk image file and specifies the byte
+offset of the filesystem image in the file.
+
+For the DOS and Windows installers, the -m and -a options can be used
+on hard drives to write a Master Boot Record (MBR), and to mark the
+specific partition active.
+
+If the Shift or Alt keys are held down during boot, or the Caps or Scroll
+locks are set, Syslinux will display a LILO-style "boot:" prompt.  The
+user can then type a kernel file name followed by any kernel parameters.
+The Syslinux loader does not need to know about the kernel file in
+advance; all that is required is that it is a file located in the root
+directory on the disk.
+
+There are two versions of the Linux installer; one in the "mtools"
+directory which requires no special privilege (other than write
+permission to the device where you are installing) but requires the
+mtools program suite to be available, and one in the "unix" directory
+which requires root privilege.
+
+
+   ++++ CONFIGURATION FILE ++++
+
+All the configurable defaults in SYSLINUX can be changed by putting a
+file called "syslinux.cfg" in the root directory of the boot disk.
+
+This is a text file in either UNIX or DOS format, containing one or
+more of the following items (case is insensitive for keywords; upper
+case is used here to indicate that a word should be typed verbatim):
+
+Starting with version 3.35, the configuration file can also be in
+either the /boot/syslinux or /syslinux directories (searched in that
+order.)  If that is the case, then all filenames are assumed to be
+relative to that same directory, unless preceded with a slash or
+backslash.
+
+All options here applies to PXELINUX, ISOLINUX and EXTLINUX as well as
+SYSLINUX unless otherwise noted.  See the respective .txt files.
+
+# comment
+	A comment line.  The whitespace after the hash mark is mandatory.
+
+INCLUDE filename
+	Inserts the contents of another file at this point in the
+	configuration file. Files can currently be nested up to 16
+	levels deep, but it is not guaranteed that more than 8 levels
+	will be supported in the future.
+
+DEFAULT kernel options...
+        Sets the default command line.  If Syslinux boots automatically,
+        it will act just as if the entries after DEFAULT had been typed
+        in at the "boot:" prompt.
+
+	If no configuration file is present, or no DEFAULT entry is
+        present in the config file, an error message is displayed and
+	the boot: prompt is shown.
+
+UI module options...
+	Selects a specific user interface module (typically menu.c32
+	or vesamenu.c32).  The command-line interface treats this as a
+	directive that overrides the DEFAULT and PROMPT directives.
+
+APPEND options...
+        Add one or more options to the kernel command line.  These are
+        added both for automatic and manual boots.  The options are
+        added at the very beginning of the kernel command line,
+        usually permitting explicitly entered kernel options to override
+        them.  This is the equivalent of the LILO "append" option.
+
+IPAPPEND flag_val			[PXELINUX only]
+	The IPAPPEND option is available only on PXELINUX.  The
+	flag_val is an OR of the following options:
+
+	1: indicates that an option of the following format
+	should be generated and added to the kernel command line:
+
+		ip=<client-ip>:<boot-server-ip>:<gw-ip>:<netmask>
+
+	... based on the input from the DHCP/BOOTP or PXE boot server.
+
+	NOTE: The use of this option is no substitute for running a
+	DHCP client in the booted system.  Without regular renewals,
+	the lease acquired by the PXE BIOS will expire, making the
+	IP address available for reuse by the DHCP server.
+
+	2: indicates that an option of the following format
+	should be generated and added to the kernel command line:
+
+		BOOTIF=<hardware-address-of-boot-interface>
+
+	... in dash-separated hexadecimal with leading hardware type
+	(same as for the configuration file; see pxelinux.txt.)
+
+	This allows an initrd program to determine from which
+	interface the system booted.
+
+	4: indicates that an option of the following format
+	should be generated and added to the kernel command line:
+
+		SYSUUID=<system uuid>
+
+	... in lower case hexadecimal in the format normally used for
+	UUIDs (same as for the configuration file; see pxelinux.txt.)
+
+LABEL label
+    KERNEL image
+    APPEND options...
+    IPAPPEND flag_val			[PXELINUX only]
+	Indicates that if "label" is entered as the kernel to boot,
+        Syslinux should instead boot "image", and the specified APPEND
+	and IPAPPEND options should be used instead of the ones
+        specified in the global section of the file (before the first
+        LABEL command.)  The default for "image" is the same as
+        "label", and if no APPEND is given the default is to use the
+        global entry (if any).
+
+	Starting with version 3.62, the number of LABEL statements is
+	virtually unlimited.
+
+        Note that LILO uses the syntax:
+        image = mykernel
+          label = mylabel
+          append = "myoptions"
+
+        ... whereas Syslinux uses the syntax:
+        label mylabel
+          kernel mykernel
+          append myoptions
+
+	Note: The "kernel" doesn't have to be a Linux kernel; it can
+	      be a boot sector or a COMBOOT file (see below.)
+
+	Since version 3.32 label names are no longer mangled into DOS
+	format (for SYSLINUX.)
+
+    The following commands are available after a LABEL statement:
+
+    LINUX image			- Linux kernel image (default)
+    BOOT image			- Bootstrap program (.bs, .bin)
+    BSS image			- BSS image (.bss)
+    PXE image			- PXE Network Bootstrap Program (.0)
+    FDIMAGE image		- Floppy disk image (.img)
+    COMBOOT image		- COMBOOT program (.com, .cbt)
+    COM32 image			- COM32 program (.c32)
+    CONFIG image		- New configuration file
+	Using one of these keywords instead of KERNEL forces the
+	filetype, regardless of the filename.
+
+	CONFIG means restart the boot loader using a different
+	configuration file.
+
+    APPEND -
+        Append nothing.  APPEND with a single hyphen as argument in a
+        LABEL section can be used to override a global APPEND.
+
+    LOCALBOOT type			[ISOLINUX, PXELINUX]
+	On PXELINUX, specifying "LOCALBOOT 0" instead of a "KERNEL"
+	option means invoking this particular label will cause a local
+	disk boot instead of booting a kernel.
+
+	The argument 0 means perform a normal boot.  The argument 4
+	will perform a local boot with the Universal Network Driver
+	Interface (UNDI) driver still resident in memory.  Finally,
+	the argument 5 will perform a local boot with the entire PXE
+	stack, including the UNDI driver, still resident in memory.
+	All other values are undefined.  If you don't know what the
+	UNDI or PXE stacks are, don't worry -- you don't want them,
+	just specify 0.
+
+	On ISOLINUX, the "type" specifies the local drive number to
+	boot from; 0x00 is the primary floppy drive and 0x80 is the
+	primary hard drive.  The special value -1 causes ISOLINUX to
+	report failure to the BIOS, which, on recent BIOSes, should
+	mean that the next boot device in the boot sequence should be
+	activated.
+
+    INITRD initrd_file
+	Starting with version 3.71, an initrd can be specified in a
+	separate statement (INITRD) instead of as part of the APPEND
+	statement; this functionally appends "initrd=initrd_file" to
+	the kernel command line.
+
+	It supports multiple filenames separated by commas.
+	This is mostly useful for initramfs, which can be composed of
+	multiple separate cpio or cpio.gz archives.
+	Note: all files except the last one are zero-padded to a
+	4K page boundary.  This should not affect initramfs.
+
+IMPLICIT flag_val
+        If flag_val is 0, do not load a kernel image unless it has been
+        explicitly named in a LABEL statement.  The default is 1.
+
+ALLOWOPTIONS flag_val
+	If flag_val is 0, the user is not allowed to specify any
+	arguments on the kernel command line.  The only options
+	recognized are those specified in an APPEND statement.  The
+	default is 1.
+
+TIMEOUT timeout
+        Indicates how long to wait at the boot: prompt until booting
+        automatically, in units of 1/10 s.  The timeout is cancelled as
+        soon as the user types anything on the keyboard, the assumption
+        being that the user will complete the command line already
+        begun.  A timeout of zero will disable the timeout completely,
+        this is also the default.
+
+TOTALTIMEOUT timeout
+        Indicates how long to wait until booting automatically, in
+	units of 1/10 s.  This timeout is *not* cancelled by user
+	input, and can thus be used to deal with serial port glitches
+	or "the user walked away" type situations.  A timeout of zero
+	will disable the timeout completely, this is also the default.
+
+	Both TIMEOUT and TOTALTIMEOUT can be used together, for
+	example:
+
+		# Wait 5 seconds unless the user types something, but
+		# always boot after 15 minutes.
+		TIMEOUT 50
+		TOTALTIMEOUT 9000
+
+ONTIMEOUT kernel options...
+	Sets the command line invoked on a timeout.  Normally this is
+	the same thing as invoked by "DEFAULT".  If this is specified,
+	then "DEFAULT" is used only if the user presses <Enter> to
+	boot.
+
+ONERROR kernel options...
+	If a kernel image is not found (either due to it not existing,
+	or because IMPLICIT is set), run the specified command.  The
+	faulty command line is appended to the specified options, so
+	if the ONERROR directive reads as:
+
+		ONERROR xyzzy plugh
+
+	... and the command line as entered by the user is:
+
+		foo bar baz
+
+	... Syslinux will execute the following as if entered by the
+	user:
+
+		xyzzy plugh foo bar baz
+
+SERIAL port [[baudrate] flowcontrol]
+	Enables a serial port to act as the console.  "port" is a
+	number (0 = /dev/ttyS0 = COM1, etc.) or an I/O port address
+	(e.g. 0x3F8); if "baudrate" is omitted, the baud rate defaults
+	to 9600 bps.  The serial parameters are hardcoded to be 8
+	bits, no parity, 1 stop bit.
+
+	"flowcontrol" is a combination of the following bits:
+	0x001 - Assert DTR
+	0x002 - Assert RTS
+	0x008 - Enable interrupts
+	0x010 - Wait for CTS assertion
+	0x020 - Wait for DSR assertion
+	0x040 - Wait for RI assertion
+	0x080 - Wait for DCD assertion
+	0x100 - Ignore input unless CTS asserted
+	0x200 - Ignore input unless DSR asserted
+	0x400 - Ignore input unless RI asserted
+	0x800 - Ignore input unless DCD asserted
+
+	All other bits are reserved.
+
+	Typical values are:
+
+	    0 - No flow control (default)
+	0x303 - Null modem cable detect
+	0x013 - RTS/CTS flow control
+	0x813 - RTS/CTS flow control, modem input
+	0x023 - DTR/DSR flow control
+	0x083 - DTR/DCD flow control
+
+	For the SERIAL directive to be guaranteed to work properly, it
+	should be the first directive in the configuration file.
+
+	NOTE: "port" values from 0 to 3 means the first four serial
+	ports detected by the BIOS.  They may or may not correspond to
+	the legacy port values 0x3F8, 0x2F8, 0x3E8, 0x2E8.
+
+	Enabling interrupts (setting the 0x008 bit) may give better
+	responsiveness without setting the NOHALT option, but could
+	potentially cause problems with buggy BIOSes.
+
+NOHALT flag_val
+	If flag_val is 1, don't halt the processor while idle.
+	Halting the processor while idle significantly reduces the
+	power consumption, but can cause poor responsiveness to the
+	serial console, especially when using scripts to drive the
+	serial console, as opposed to human interaction.
+
+CONSOLE flag_val
+	If flag_val is 0, disable output to the normal video console.
+	If flag_val is 1, enable output to the video console (this is
+	the default.)
+
+	Some BIOSes try to forward this to the serial console and
+	sometimes make a total mess thereof, so this option lets you
+	disable the video console on these systems.
+
+FONT filename
+	Load a font in .psf format before displaying any output
+	(except the copyright line, which is output as ldlinux.sys
+	itself is loaded.)  Syslinux only loads the font onto the
+	video card; if the .psf file contains a Unicode table it is
+	ignored.  This only works on EGA and VGA cards; hopefully it
+	should do nothing on others.
+
+KBDMAP keymap
+	Install a simple keyboard map.  The keyboard remapper used is
+	*very* simplistic (it simply remaps the keycodes received from
+	the BIOS, which means that only the key combinations relevant
+	in the default layout -- usually U.S. English -- can be
+	mapped) but should at least help people with AZERTY keyboard
+	layout and the locations of = and , (two special characters
+	used heavily on the Linux kernel command line.)
+
+	The included program keytab-lilo.pl from the LILO distribution
+	can be used to create such keymaps.  The file keytab-lilo.txt
+	contains the documentation for this program.
+
+DISPLAY filename
+	Displays the indicated file on the screen at boot time (before
+        the boot: prompt, if displayed).  Please see the section below
+        on DISPLAY files.
+
+        NOTE: If the file is missing, this option is simply ignored.
+
+SAY message
+	Prints the message on the screen.
+
+PROMPT flag_val
+        If flag_val is 0, display the boot: prompt only if the Shift or Alt
+        key is pressed, or Caps Lock or Scroll lock is set (this is the
+        default).  If flag_val is 1, always display the boot: prompt.
+
+NOESCAPE flag_val
+	If flag_val is set to 1, ignore the Shift/Alt/Caps Lock/Scroll
+	Lock escapes.  Use this (together with PROMPT 0) to force the
+	default boot alternative.
+
+NOCOMPLETE flag_val
+	If flag_val is set to 1, the Tab key does not display labels
+	at the boot: prompt.
+
+F1 filename
+F2 filename
+   ...etc...
+F9 filename
+F10 filename
+F11 filename
+F12 filename
+        Displays the indicated file on the screen when a function key is
+        pressed at the boot: prompt.  This can be used to implement
+        pre-boot online help (presumably for the kernel command line
+        options.)  Please see the section below on DISPLAY files.
+
+	When using the serial console, press <Ctrl-F><digit> to get to
+	the help screens, e.g. <Ctrl-F><2> to get to the F2 screen.
+	For F10-F12, hit <Ctrl-F><A>, <Ctrl-F>B, <Ctrl-F>C.  For
+	compatibility with earlier versions, F10 can also be entered as
+	<Ctrl-F>0.
+
+Blank lines are ignored.
+
+Note that the configuration file is not completely decoded.  Syntax
+different from the one described above may still work correctly in this
+version of Syslinux, but may break in a future one.
+
+
+   ++++ DISPLAY FILE FORMAT ++++
+
+DISPLAY and function-key help files are text files in either DOS or UNIX
+format (with or without <CR>).  In addition, the following special codes
+are interpreted:
+
+<FF>                                    <FF> = <Ctrl-L> = ASCII 12
+        Clear the screen, home the cursor.  Note that the screen is
+        filled with the current display color.
+
+<SI><bg><fg>                            <SI> = <Ctrl-O> = ASCII 15
+        Set the display colors to the specified background and
+        foreground colors, where <bg> and <fg> are hex digits,
+        corresponding to the standard PC display attributes:
+
+        0 = black               8 = dark grey
+        1 = dark blue           9 = bright blue
+        2 = dark green          a = bright green
+        3 = dark cyan           b = bright cyan
+        4 = dark red            c = bright red
+        5 = dark purple         d = bright purple
+        6 = brown               e = yellow
+        7 = light grey          f = white
+
+        Picking a bright color (8-f) for the background results in the
+        corresponding dark color (0-7), with the foreground flashing.
+
+	Colors are not visible over the serial console.
+
+<CAN>filename<newline>			<CAN> = <Ctrl-X> = ASCII 24
+	If a VGA display is present, enter graphics mode and display
+	the graphic included in the specified file.  The file format
+	is an ad hoc format called LSS16; the included Perl program
+	"ppmtolss16" can be used to produce these images.  This Perl
+	program also includes the file format specification.
+
+	The image is displayed in 640x480 16-color mode.  Once in
+	graphics mode, the display attributes (set by <SI> code
+	sequences) work slightly differently: the background color is
+	ignored, and the foreground colors are the 16 colors specified
+	in the image file.  For that reason, ppmtolss16 allows you to
+	specify that certain colors should be assigned to specific
+	color indicies.
+
+	Color indicies 0 and 7, in particular, should be chosen with
+	care: 0 is the background color, and 7 is the color used for
+	the text printed by Syslinux itself.
+
+<EM>					<EM> = <Ctrl-Y> = ASCII 25
+	If we are currently in graphics mode, return to text mode.
+

+<Esc>		interrupt boot in progress
+<Ctrl-N>	display network information (PXELINUX only)
+
+
+   ++++ COMBOOT IMAGES AND OTHER OPERATING SYSTEMS ++++
+
+This version of Syslinux supports chain loading of other operating
+systems (such as MS-DOS and its derivatives, including Windows 95/98),
+as well as COMBOOT-style standalone executables (a subset of DOS .COM
+files; see separate section below.)
+
+Chain loading requires the boot sector of the foreign operating system
+to be stored in a file in the root directory of the filesystem.
+Because neither Linux kernels, boot sector images, nor COMBOOT files
+have reliable magic numbers, Syslinux will look at the file extension.
+The following extensions are recognized (case insensitive):
+
+  none or other	Linux kernel image
+  .0		PXE bootstrap program (NBP) [PXELINUX only]
+  .bin		"CD boot sector" [ISOLINUX only]
+  .bs		Boot sector [SYSLINUX only]
+  .bss		Boot sector, DOS superblock will be patched in [SYSLINUX only]
+  .c32		COM32 image (32-bit COMBOOT)
+  .cbt		COMBOOT image (not runnable from DOS)
+  .com		COMBOOT image (runnable from DOS)
+  .img		Disk image [ISOLINUX only]
+
+For filenames given on the command line, Syslinux will search for the
+file by adding extensions in the order listed above if the plain
+filename is not found.  Filenames in KERNEL statements must be fully
+qualified.
+
+If this is specified with one of the keywords LINUX, BOOT, BSS,
+FDIMAGE, COMBOOT, COM32, or CONFIG instead of KERNEL, the filetype is
+considered to be the one specified regardless of the filename.
+
+
+      ++++ BOOTING DOS (OR OTHER SIMILAR OPERATING SYSTEMS) ++++
+
+This section applies to SYSLINUX only, not to PXELINUX or ISOLINUX.
+See isolinux.txt for an equivalent procedure for ISOLINUX.
+
+This is the recommended procedure for creating a SYSLINUX disk that
+can boot either DOS or Linux.  This example assumes the drive is A: in
+DOS and /dev/fd0 in Linux; for other drives, substitute the
+appropriate drive designator.
+
+   ---- Linux procedure ----
+
+1. Make a DOS bootable disk.  This can be done either by specifying
+   the /s option when formatting the disk in DOS, or by running the
+   DOS command SYS (this can be done under DOSEMU if DOSEMU has
+   direct device access to the relevant drive):
+
+	format a: /s
+   or
+	sys a:
+
+2. Boot Linux.  Copy the DOS boot sector from the disk into a file:
+
+	dd if=/dev/fd0 of=dos.bss bs=512 count=1
+
+3. Run SYSLINUX on the disk:
+
+	syslinux /dev/fd0
+
+4. Mount the disk and copy the DOS boot sector file to it.  The file
+   *must* have extension .bss:
+
+	mount -t msdos /dev/fd0 /mnt
+	cp dos.bss /mnt
+
+5. Copy the Linux kernel image(s), initrd(s), etc to the disk, and
+   create/edit syslinux.cfg and help files if desired:
+
+	cp vmlinux /mnt
+	cp initrd.gz /mnt
+
+6. Unmount the disk (if applicable.)
+
+	umount /mnt
+
+   ---- DOS/Windows procedure ----
+
+To make this installation in DOS only, you need the utility copybs.com
+(included with Syslinux) as well as the syslinux.com installer.  If
+you are on an WinNT-based system (WinNT, Win2k, WinXP or later), use
+syslinux.exe instead.
+
+1. Make a DOS bootable disk.  This can be done either by specifying
+   the /s option when formatting the disk in DOS, or by running the
+   DOS command SYS:
+
+	format a: /s
+   or
+	sys a:
+
+2. Copy the DOS boot sector from the disk into a file.  The file
+   *must* have extension .bss:
+
+	copybs a: a:dos.bss
+
+3. Run SYSLINUX on the disk:
+
+	syslinux a:
+
+4. Copy the Linux kernel image(s), initrd(s), etc to the disk, and
+   create/edit syslinux.cfg and help files if desired:
+
+	copy vmlinux a:
+	copy initrd.gz a:
+
+
+   ++++ COMBOOT EXECUTABLES ++++
+
+Syslinux supports simple standalone programs, using a file format
+similar to DOS ".com" files.  A 32-bit version, called COM32, is also
+provided.  A simple API provides access to a limited set of filesystem
+and console functions.
+
+See the file comboot.txt for more information on COMBOOT and COM32
+programs.
+
+
+   ++++ NOVICE PROTECTION ++++
+
+Syslinux will attempt to detect booting on a machine with too little
+memory, which means the Linux boot sequence cannot complete.  If so, a
+message is displayed and the boot sequence aborted.  Holding down the
+Ctrl key while booting disables this feature.
+
+Any file that SYSLINUX uses can be marked hidden, system or readonly
+if so is convenient; SYSLINUX ignores all file attributes.  The
+SYSLINUX installed automatically sets the readonly/hidden/system
+attributes on LDLINUX.SYS.
+
+
+   ++++ NOTES ON BOOTABLE CD-ROMS ++++
+
+SYSLINUX can be used to create bootdisk images for El
+Torito-compatible bootable CD-ROMs.  However, it appears that many
+BIOSes are very buggy when it comes to booting CD-ROMs.  Some users
+have reported that the following steps are helpful in making a CD-ROM
+that is bootable on the largest possible number of machines:
+
+	a) Use the -s (safe, slow and stupid) option to SYSLINUX;
+	b) Put the boot image as close to the beginning of the
+	   ISO 9660 filesystem as possible.
+
+A CD-ROM is so much faster than a floppy that the -s option shouldn't
+matter from a speed perspective.
+
+Of course, you probably want to use ISOLINUX instead.  See isolinux.txt.
+
+
+   ++++ BOOTING FROM A FAT FILESYSTEM PARTITION ON A HARD DISK ++++
+
+SYSLINUX can boot from a FAT filesystem partition on a hard disk
+(including FAT32).  The installation procedure is identical to the
+procedure for installing it on a floppy, and should work under either
+DOS or Linux.  To boot from a partition, SYSLINUX needs to be launched
+from a Master Boot Record or another boot loader, just like DOS itself
+would.
+
+Under DOS, you can install a standard simple MBR on the primary hard
+disk by running the command:
+
+	FDISK /MBR
+
+Then use the FDISK command to mark the appropriate partition active.
+
+A simple MBR, roughly on par with the one installed by DOS (but
+unencumbered), is included in the SYSLINUX distribution.  To install
+it under Linux, simply type:
+
+	cat mbr.bin > /dev/XXX
+
+... where /dev/XXX is the device you wish to install it on.
+
+Under DOS or Win32, you can install the SYSLINUX MBR with the -m
+option to the SYSLINUX installer, and use the -a option to mark the
+current partition active:
+
+	syslinux -ma c:
+
+Note that this will also install SYSLINUX on the specified partition.
+
+
+   ++++ HARDWARE INFORMATION +++
+
+I have started to maintain a web page of hardware with known
+problems.  There are, unfortunately, lots of broken hardware out
+there; especially early PXE stacks (for PXELINUX) have lots of
+problems.
+
+A list of problems, and workarounds (if known), is maintained at:
+
+	http://syslinux.zytor.com/hardware.php
+
+
+   ++++ BOOT LOADER IDS USED ++++
+
+The Linux boot protocol supports a "boot loader ID", a single byte
+where the upper nybble specifies a boot loader family (3 = Syslinux)
+and the lower nybble is version or, in the case of Syslinux, media:
+
+	0x31 (49) = SYSLINUX
+	0x32 (50) = PXELINUX
+	0x33 (51) = ISOLINUX
+	0x34 (52) = EXTLINUX
+
+In recent versions of Linux, this ID is available as
+/proc/sys/kernel/bootloader_type.
+
+
+   ++++ BUG REPORTS ++++
+
+I would appreciate hearing of any problems you have with Syslinux.  I
+would also like to hear from you if you have successfully used Syslinux,
+*especially* if you are using it for a distribution.
+
+If you are reporting problems, please include all possible information
+about your system and your BIOS; the vast majority of all problems
+reported turn out to be BIOS or hardware bugs, and I need as much
+information as possible in order to diagnose the problems.
+
+There is a mailing list for discussion among Syslinux users and for
+announcements of new and test versions.  To join, or to browse the
+archive, go to:
+
+   http://www.zytor.com/mailman/listinfo/syslinux
+
+Please DO NOT send HTML messages or attachments to the mailing list
+(including multipart/alternative or similar.)  All such messages will
+be bounced.

+The proper mode to boot a USB key drive in is "USB-HDD".  That is the
+ONLY mode in which the C/H/S geometry encoded on the disk itself
+doesn't have to match what the BIOS thinks it is.  Since geometry on
+USB drives is completely arbitrary, and can vary from BIOS to BIOS,
+this is the only mode which will work in general.
+
+Some BIOSes have been reported (in particular, certain versions of the
+Award BIOS) that cannot boot USB keys in "USB-HDD" mode.  This is a
+very serious BIOS bug, but it is unfortunately rather typical of the
+kind of quality we're seeing out of major BIOS vendors these days.  On
+these BIOSes, you're generally stuck booting them in USB-ZIP mode.
+
+THIS MEANS THE FILESYSTEM IMAGE ON THE DISK HAS TO HAVE A CORRECT
+ZIPDRIVE-COMPATIBLE GEOMETRY.
+
+A standard zipdrive (both the 100 MB and the 250 MB varieties) have a
+"geometry" of 64 heads, 32 sectors, and are partitioned devices with a
+single partition 4 (unlike most other media of this type which uses
+partition 1.)  The 100 MB variety has 96 cylinders, and the 250 MB
+variety has 239 cylinders; but any number of cylinders will do as
+appropriate for the size device you have.  For example, if your device
+reports when inserted into a Linux system:
+
+usb-storage: device found at 4
+  Vendor: 32MB      Model: HardDrive         Rev: 1.88
+  Type:   Direct-Access                      ANSI SCSI revision: 02
+SCSI device sda: 64000 512-byte hdwr sectors (33 MB)
+
+... you would have 64000/(64*32) = 31.25 cylinders; round down to 31.
+
+The script "mkdiskimage" which is supplied with the syslinux
+distribution can be used to initialize USB keys in a Zip-like fashion.
+To do that, calculate the correct number of cylinders (31 in the
+example above), and, if your USB key is /dev/sda (CHECK THE KERNEL
+MESSAGES CAREFULLY - IF YOU ENTER THE WRONG DISK DRIVE IT CANNOT BE
+RECOVERED), run:
+
+	mkdiskimage -4 /dev/sda 0 64 32
+
+(The 0 means automatically determine the size of the device, and -4
+means mimic a zipdisk by using partition 4.)
+
+Then you should be able to run
+
+	syslinux /dev/sda4
+
+... and mount /dev/sda4 and put your files on it as needed.

+Change log for eltorito.asm, by Bart Lagerweij
+
+Jun 25, 2009 - License source code under the MIT license
+
+Jun 6, 2002 - v1.2
+Eltorito.sys does now also finds the correct driver number for the booted CD-Rom
+on a Dell PC with very buggy BIOS. It does not clear the carry flag after a
+succesfull call to int13/ax=4b01h call. Other PC's also using Phoenix BIOS
+version 1.10 A14, or alike maybe also benefit from this "workaround".
+
+Mar 9, 2002
+- All read requests are now retried 5 times.
+- Bug fix, had...
+	cmp	ax, 3FFFh		;Too large?
+	ja	ReadLBad		;If yes
+  seperated from...
+	mov	ax,es:[bx+18]		;Get number of sectors to read
+	mov	word ptr [SpecPkt+2],ax
+  so, it was checking "wild" ax values...
+- Some cleanup and small changes
+- The tracers give trouble when using SHCD..
+- Reverted proc ReadL back to Rev. 0.15BETA
+
+Mar 5, 2002
+- Bug fix, when changing CD media some machines would "hang" in the PriVolDesc
+  routine.
+- Added printing of TRACER characters to trace the bug above
+- Major cleanup and now using ASCIIZ strings
+
+May 9, 2001
+- Fixed a "pad devicename with spaces" bug, this only happened when a device
+  name was used with less than 8 characters, for example, "MSCD000" became
+  "MSCD000("
+- Bug fix, when eltorito.sys was called with invalid command line parameters,
+  garbage was printed and sometimes followed by "system halted" that has been
+  there since the very first version of eltorito.sys. I know that because I
+  had the bug back then. When loading eltorito.sys using a device loader,
+  for example "device.com eltorito.sys /test:123" garbage was printed instead
+  of "No device name found." "driver not installed".
+  Changed the error message to include a "usage" string.
+
+May 8, 2001
+- If diskemu.bin is loaded eltorito.sys uses the drivenumber from diskemu
+  A call is made to "diskemu/Get status" (INT13/AX=5400) and the drivenumber is returned in CL
+  This should fix boot problems on Dell PCs (YES!)
+  When diskemu.bin is not loaded, eltorito still loops all drive numbers using eltorito calls.
+- Removed "press Escape..."
+- When the Alt-key is pressed (and holded) more info is printed and eltorito.sys halts
+

+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+		    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+			    NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+	Appendix: How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) 19yy  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program; if not, write to the Free Software
+    Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) 19yy name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989
+  Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+gPXE README File
+
+gPXE is an implementation of the PXE specification for network
+booting, with extensions to allow additional features such as booting
+via HTTP, iSCSI, and AoE.  
+
+In generally, gPXE is compatible with the industry-standard PXE
+specification, and also supports Etherboot .nbi file loading and some
+additional protocols and features.
+
+For more detailed information about gPXE, please visit our project
+website at: http://etherboot.org/
+
+BUILDING gPXE IMAGE FROM SOURCE
+
+If you don't want to install development tools, and have access to the
+Web, you can get gPXE and Etherboot ROM images made on demand from
+http://rom-o-matic.net/
+
+If you would like to compile gPXE images from source, here are some tips.
+
+We normally compile gPXE images on x86, 32-bit Linux machines. It is
+possible to also use x86-64 machines. We use gcc compiler options to
+create 32-bit output.
+
+It is important to have the necessary software  packages installed.  A gcc-based
+toolchain is required.
+
+The following packages (at least) are required:
+
+  - a gcc tool chain (gcc 3.x or gcc 4.x)
+  - binutils
+  - perl
+  - syslinux
+  - mtools
+  
+To test your environment, cd to the "src" directory and type:
+
+   make
+
+You should see a lot of output, and when it stops, the "bin" directory
+should be populated with gPXE images and object files.
+
+To learn more about what to build and how to use gPXE, please visit our
+project website at http://etherboot.org/ , particularly the "howto" section.
+
+CONTACTING US
+
+Pointers to our project mailing lists are on http://etherboot.org/
+
+Real-time help is often available on IRC on the #etherboot channel of
+irc.freenode.net.

+Etherboot/NILO i386 initialisation path and external call interface
+===================================================================
+
+1. Background
+
+GCC compiles 32-bit code.  It is capable of producing
+position-independent code, but the resulting binary is about 25%
+bigger than the corresponding fixed-position code.  Since one main use
+of Etherboot is as firmware to be burned into an EPROM, code size must
+be kept as small as possible.
+
+This means that we want to compile fixed-position code with GCC, and
+link it to have a predetermined start address.  The problem then is
+that we must know the address that the code will be loaded to when it
+runs.  There are several ways to solve this:
+
+1. Pick an address, link the code with this start address, then make
+   sure that the code gets loaded at that location.  This is
+   problematic, because we may pick an address that we later end up
+   wanting to use to load the operating system that we're booting.
+
+2. Pick an address, link the code with this start address, then set up
+   virtual addressing so that the virtual addresses match the
+   link-time addresses regardless of the real physical address that
+   the code is loaded to.  This enables us to relocate Etherboot to
+   the top of high memory, where it will be out of the way of any
+   loading operating system.
+
+3. Link the code with a text start address of zero and a data start
+   address also of zero.  Use 16-bit real mode and the
+   quasi-position-independence it gives you via segment addressing.
+   Doing this requires that we generate 16-bit code, rather than
+   32-bit code, and restricts us to a maximum of 64kB in each segment.
+
+There are other possible approaches (e.g. including a relocation table
+and code that performs standard dynamic relocation), but the three
+options listed above are probably the best available.
+
+Etherboot can be invoked in a variety of ways (ROM, floppy, as a PXE
+NBP, etc).  Several of these ways involve control being passed to
+Etherboot with the CPU in 16-bit real mode.  Some will involve the CPU
+being in 32-bit protected mode, and there's an outside chance that
+some may involve the CPU being in 16-bit protected mode.  We will
+almost certainly have to effect a CPU mode change in order to reach
+the mode we want to be in to execute the C code.
+
+Additionally, Etherboot may wish to call external routines, such as
+BIOS interrupts, which must be called in 16-bit real mode.  When
+providing a PXE API, Etherboot must provide a mechanism for external
+code to call it from 16-bit real mode.
+
+Not all i386 builds of Etherboot will want to make real-mode calls.
+For example, when built for LinuxBIOS rather than the standard PCBIOS,
+no real-mode calls are necessary.
+
+For the ultimate in PXE compatibility, we may want to build Etherboot
+to run permanently in real mode.
+
+There is a wide variety of potential combinations of mode switches
+that we may wish to implement.  There are additional complications,
+such as the inability to access a high-memory stack when running in
+real mode.
+
+2. Transition libraries
+
+To handle all these various combinations of mode switches, we have
+several "transition" libraries in Etherboot.  We also have the concept
+of an "internal" and an "external" environment.  The internal
+environment is the environment within which we can execute C code.
+The external environment is the environment of whatever external code
+we're trying to interface to, such as the system BIOS or a PXE NBP.
+
+As well as having a separate addressing scheme, the internal
+environment also has a separate stack.
+
+The transition libraries are:
+
+a) librm
+
+librm handles transitions between an external 16-bit real-mode
+environment and an internal 32-bit protected-mode environment with
+virtual addresses.
+
+b) libkir
+
+libkir handles transitions between an external 16-bit real-mode (or
+16:16 or 16:32 protected-mode) environment and an internal 16-bit
+real-mode (or 16:16 protected-mode) environment.
+
+c) libpm
+
+libpm handles transitions between an external 32-bit protected-mode
+environment with flat physical addresses and an internal 32-bit
+protected-mode environment with virtual addresses.
+
+The transition libraries handle the transitions required when
+Etherboot is started up for the first time, the transitions required
+to execute any external code, and the transitions required when
+Etherboot exits (if it exits).  When Etherboot provides a PXE API,
+they also handle the transitions required when a PXE client makes a
+PXE API call to Etherboot.
+
+Etherboot may use multiple transition libraries.  For example, an
+Etherboot ELF image does not require librm for its initial transitions
+from prefix to runtime, but may require librm for calling external
+real-mode functions.
+
+3. Setup and initialisation
+
+Etherboot is conceptually divided into the prefix, the decompressor,
+and the runtime image.  (For non-compressed images, the decompressor
+is a no-op.)  The complete image comprises all three parts and is
+distinct from the runtime image, which exclude the prefix and the
+decompressor.
+
+The prefix does several tasks:
+
+  Load the complete image into memory.  (For example, the floppy
+  prefix issues BIOS calls to load the remainder of the complete image
+  from the floppy disk into RAM, and the ISA ROM prefix copies the ROM
+  contents into RAM for faster access.)
+
+  Call the decompressor, if the runtime image is compressed.  This
+  decompresses the runtime image.
+
+  Call the runtime image's setup() routine.  This is a routine
+  implemented in assembly code which sets up the internal environment
+  so that C code can execute.
+
+  Call the runtime image's arch_initialise() routine.  This is a
+  routine implemented in C which does some basic startup tasks, such
+  as initialising the console device, obtaining a memory map and
+  relocating the runtime image to high memory.
+
+  Call the runtime image's arch_main() routine.  This records the exit
+  mechanism requested by the prefix and calls main().  (The prefix
+  needs to register an exit mechanism because by the time main()
+  returns, the memory occupied by the prefix has most likely been
+  overwritten.)
+
+When acting as a PXE ROM, the ROM prefix contains an UNDI loader
+routine in addition to its usual code.  The UNDI loader performs a
+similar sequence of steps:
+
+  Load the complete image into memory.
+
+  Call the decompressor.
+
+  Call the runtime image's setup() routine.
+
+  Call the runtime image's arch_initialise() routine.
+
+  Call the runtime image's install_pxe_stack() routine.
+
+  Return to caller.
+
+The runtime image's setup() routine will perform the following steps:
+
+  Switch to the internal environment using an appropriate transition
+  library.  This will record the parameters of the external
+  environment.
+
+  Set up the internal environment: load a stack, and set up a GDT for
+  virtual addressing if virtual addressing is to be used.
+
+  Switch back to the external environment using the transition
+  library.  This will record the parameters of the internal
+  environment.
+
+Once the setup() routine has returned, the internal environment has been
+set up ready for C code to run.  The prefix can call C routines using
+a function from the transition library.
+
+The runtime image's arch_initialise() routine will perform the
+following steps:
+
+  Zero the bss
+
+  Initialise the console device(s) and print a welcome message.
+
+  Obtain a memory map via the INT 15,E820 BIOS call or suitable
+  fallback mechanism. [not done if libkir is being used]
+
+  Relocate the runtime image to the top of high memory. [not done if
+  libkir is being used]
+
+  Install librm to base memory. [done only if librm is being used]
+
+  Call initialise().
+
+  Return to the prefix, setting registers to indicate to the prefix
+  the new location of the transition library, if applicable.  Which
+  registers these are is specific to the transition library being
+  used.
+
+Once the arch_initialise() routine has returned, the prefix will
+probably call arch_main().

+ * occurred every time undinet_poll() is called.  This isn't too much
+ * of a hack; PCI devices share IRQs and so the first thing that a
+ * proper ISR should do is call PXENV_UNDI_ISR to determine whether or
+ * not the UNDI NIC generated the interrupt; there is no harm done by
+ * spurious calls to PXENV_UNDI_ISR.  Similarly, we wouldn't be
+ * handling them any more rapidly than the usual rate of
+ * undinet_poll() being called even if we did implement a full ISR.
+ * So it should work.  Ha!
+ *
+ * Addendum (21/10/03).  Some cards don't play nicely with this trick,
+ * so instead of doing it the easy way we have to go to all the hassle
+ * of installing a genuine interrupt service routine and dealing with
+ * the wonderful 8259 Programmable Interrupt Controller.  Joy.
+ *
+ * Addendum (10/07/07).  When doing things such as iSCSI boot, in
+ * which we have to co-operate with a running OS, we can't get away
+ * with the "ISR-just-increments-a-counter-and-returns" trick at all,
+ * because it involves tying up the PIC for far too long, and other
+ * interrupt-dependent components (e.g. local disks) start breaking.
+ * We therefore implement a "proper" ISR which calls PXENV_UNDI_ISR
+ * from within interrupt context in order to deassert the device
+ * interrupt, and sends EOI if applicable.

+ * to extend the data structure by adding an extra "extended
+ * attributes" field and by including critical information within this
+ * field, such as whether or not the region is enabled.  A caller who
+ * passes in only a 20-byte buffer therefore risks getting very, very
+ * misleading information.
+ *
+ * I have personally witnessed an HP BIOS that returns a value of
+ * 0x0009 in the extended attributes field.  If we don't pass this
+ * value through to the caller, 32-bit WinPE will die, usually with a
+ * PAGE_FAULT_IN_NONPAGED_AREA blue screen of death.
+ *
+ * Allow a ridiculously large maximum value (64 bytes) for the E820
+ * buffer as a guard against insufficiently creative idiots in the
+ * future.

+
+@section pxe_routing IP routing
+
+Several PXE API calls (e.g. pxenv_tftp_open() and pxenv_udp_write())
+allow for the caller to specify a "relay agent IP address", often in a
+field called "gateway" or similar.  The PXE specification states that
+"The IP layer should provide space for a minimum of four routing
+entries obtained from the default router and static route DHCP option
+tags in the DHCPACK message, plus any non-zero giaddr field from the
+DHCPOFFER message(s) accepted by the client".
+
+The DHCP static route option ("option static-routes" in dhcpd.conf)
+works only for classed IP routing (i.e. it provides no way to specify
+a subnet mask).  Since virtually everything now uses classless IP
+routing, the DHCP static route option is almost totally useless, and
+is (according to the dhcp-options man page) not implemented by any of
+the popular DHCP clients.
+
+This leaves the caller-specified "relay agent IP address", the giaddr
+field from the DHCPOFFER message(s) and the default gateway(s)
+provided via the routers option ("option routers" in dhcpd.conf) in
+the DHCPACK message.  Each of these is a default gateway address.
+It's a fair bet that the routers option should take priority over the
+giaddr field, since the routers option has to be explicitly specified
+by the DHCP server operator.  Similarly, it's fair to assume that the
+caller-specified "relay agent IP address", if present, should take
+priority over any other routing table entries.
+
+@bug Etherboot currently ignores all potential sources of routing
+information other than the first router provided to it by a DHCP
+routers option.
+
+@section pxe_x86_modes x86 processor mode restrictions
+
+On the x86 platform, different PXE API calls have different
+restrictions on the processor modes (real or protected) that can be
+used.  See the individual API call descriptions for the restrictions
+that apply to any particular call.
+
+@subsection pxe_x86_pmode16 Real mode, or protected-mode with 16-bit stack
+
+The PXE specification states that the API function can be called in
+protected mode only if the s_PXE::StatusCallout field is set to a
+non-zero value, and that the API function cannot be called with a
+32-bit stack segment.
+
+Etherboot does not enforce either of these restrictions; they seem (as
+with so much of the PXE specification) to be artifacts of the Intel
+implementation.

+ * Declaration of variables in .data16
+ *
+ * To place a variable in the .data16 segment, declare it using the
+ * pattern:
+ *
+ *   int __data16 ( foo );
+ *   #define foo __use_data16 ( foo );
+ *
+ *   extern uint32_t __data16 ( bar );
+ *   #define bar __use_data16 ( bar );
+ *
+ *   static long __data16 ( baz ) = 0xff000000UL;
+ *   #define baz __use_data16 ( baz );
+ *
+ * i.e. take a normal declaration, add __data16() around the variable
+ * name, and add a line saying "#define <name> __use_data16 ( <name> )
+ *
+ * You can then access them just like any other variable, for example
+ *
+ *   int x = foo + bar;
+ *
+ * This magic is achieved at a cost of only around 7 extra bytes per
+ * group of accesses to .data16 variables.  When using KEEP_IT_REAL,
+ * there is no extra cost.
+ *
+ * You should place variables in .data16 when they need to be accessed
+ * by real-mode code.  Real-mode assembly (e.g. as created by
+ * REAL_CODE()) can access these variables via the usual data segment.
+ * You can therefore write something like
+ *
+ *   static uint16_t __data16 ( foo );
+ *   #define foo __use_data16 ( foo )
+ *
+ *   int bar ( void ) {
+ *     __asm__ __volatile__ ( REAL_CODE ( "int $0xff\n\t"
+ *                                        "movw %ax, foo" )
+ *                            : : );
+ *     return foo;
+ *   }
+ *
+ * Variables may also be placed in .text16 using __text16 and
+ * __use_text16.  Some variables (e.g. chained interrupt vectors) fit
+ * most naturally in .text16; most should be in .data16.
+ *
+ * If you have only a pointer to a magic symbol within .data16 or
+ * .text16, rather than the symbol itself, you can attempt to extract
+ * the underlying symbol name using __from_data16() or
+ * __from_text16().  This is not for the faint-hearted; check the
+ * assembler output to make sure that it's doing the right thing.

+ * network headers have already been removed.
+ *
+ * The buffer must be large enough to contain a packet of the size
+ * negotiated via the s_PXENV_TFTP_OPEN::PacketSize field in the
+ * pxenv_tftp_open() call.  It is worth noting that the PXE
+ * specification does @b not require the caller to fill in
+ * s_PXENV_TFTP_READ::BufferSize before calling pxenv_tftp_read(), so
+ * the PXE stack is free to ignore whatever value the caller might
+ * place there and just assume that the buffer is large enough.  That
+ * said, it may be worth the caller always filling in
+ * s_PXENV_TFTP_READ::BufferSize to guard against PXE stacks that
+ * mistake it for an input parameter.
+ *
+ * The length of the TFTP data packet will be returned via
+ * s_PXENV_TFTP_READ::BufferSize.  If this length is less than the
+ * blksize negotiated via s_PXENV_TFTP_OPEN::PacketSize in the call to
+ * pxenv_tftp_open(), this indicates that the block is the last block
+ * in the file.  Note that zero is a valid length for
+ * s_PXENV_TFTP_READ::BufferSize, and will occur when the length of
+ * the file is a multiple of the blksize.
+ *
+ * The PXE specification doesn't actually state that calls to
+ * pxenv_tftp_read() will return the data packets in strict sequential
+ * order, though most PXE stacks will probably do so.  The sequence
+ * number of the packet will be returned in
+ * s_PXENV_TFTP_READ::PacketNumber.  The first packet in the file has
+ * a sequence number of one, not zero.
+ *
+ * To guard against flawed PXE stacks, the caller should probably set
+ * s_PXENV_TFTP_READ::PacketNumber to one less than the expected
+ * returned value (i.e. set it to zero for the first call to
+ * pxenv_tftp_read() and then re-use the returned s_PXENV_TFTP_READ
+ * parameter block for subsequent calls without modifying
+ * s_PXENV_TFTP_READ::PacketNumber between calls).  The caller should
+ * also guard against potential problems caused by flawed
+ * implementations returning the occasional duplicate packet, by
+ * checking that the value returned in s_PXENV_TFTP_READ::PacketNumber
+ * is as expected (i.e. one greater than that returned from the

+ * pointed to by s_PXENV_TFTP_READ_FILE::Buffer.
+ *
+ * The PXE specification does not make it clear how the caller
+ * requests that MTFTP be used rather than TFTP (or vice versa).  One
+ * reasonable guess is that setting
+ * s_PXENV_TFTP_READ_FILE::McastIPAddress to 0.0.0.0 would cause TFTP
+ * to be used instead of MTFTP, though it is conceivable that some PXE
+ * stacks would interpret that as "use the DHCP-provided multicast IP
+ * address" instead.  Some PXE stacks will not implement MTFTP at all,
+ * and will always use TFTP.
+ *
+ * It is not specified whether or not
+ * s_PXENV_TFTP_READ_FILE::TFTPSrvPort will be used as the TFTP server
+ * port for TFTP (rather than MTFTP) downloads.  Callers should assume
+ * that the only way to access a TFTP server on a non-standard port is
+ * to use pxenv_tftp_open() and pxenv_tftp_read().
+ *
+ * If s_PXENV_TFTP_READ_FILE::GatewayIPAddress is 0.0.0.0, normal IP
+ * routing will take place.  See the relevant
+ * @ref pxe_routing "implementation note" for more details.
+ *
+ * It is interesting to note that s_PXENV_TFTP_READ_FILE::Buffer is an
+ * #ADDR32_t type, i.e. nominally a flat physical address.  Some PXE
+ * NBPs (e.g. NTLDR) are known to call pxenv_tftp_read_file() in real
+ * mode with s_PXENV_TFTP_READ_FILE::Buffer set to an address above
+ * 1MB.  This means that PXE stacks must be prepared to write to areas
+ * outside base memory.  Exactly how this is to be achieved is not
+ * specified, though using INT 15,87 is as close to a standard method
+ * as any, and should probably be used.  Switching to protected-mode
+ * in order to access high memory will fail if pxenv_tftp_read_file()
+ * is called in V86 mode; it is reasonably to expect that a V86
+ * monitor would intercept the relatively well-defined INT 15,87 if it
+ * wants the PXE stack to be able to write to high memory.
+ *
+ * Things get even more interesting if pxenv_tftp_read_file() is
+ * called in protected mode, because there is then absolutely no way
+ * for the PXE stack to write to an absolute physical address.  You
+ * can't even get around the problem by creating a special "access
+ * everything" segment in the s_PXE data structure, because the
+ * #SEGDESC_t descriptors are limited to 64kB in size.
+ *
+ * Previous versions of the PXE specification (e.g. WfM 1.1a) provide
+ * a separate API call, %pxenv_tftp_read_file_pmode(), specifically to
+ * work around this problem.  The s_PXENV_TFTP_READ_FILE_PMODE
+ * parameter block splits s_PXENV_TFTP_READ_FILE::Buffer into
+ * s_PXENV_TFTP_READ_FILE_PMODE::BufferSelector and
+ * s_PXENV_TFTP_READ_FILE_PMODE::BufferOffset, i.e. it provides a
+ * protected-mode segment:offset address for the data buffer.  This
+ * API call is no longer present in version 2.1 of the PXE
+ * specification.
+ *
+ * Etherboot makes the assumption that s_PXENV_TFTP_READ_FILE::Buffer
+ * is an offset relative to the caller's data segment, when
+ * pxenv_tftp_read_file() is called in protected mode.
+ *
+ * On x86, you must set the s_PXE::StatusCallout field to a nonzero
+ * value before calling this function in protected mode.  You cannot
+ * call this function with a 32-bit stack segment.  (See the relevant
+ * @ref pxe_x86_pmode16 "implementation note" for more details.)
+ *
+ * @note Microsoft's NTLDR assumes that the filename passed in via
+ * s_PXENV_TFTP_READ_FILE::FileName will be stored in the "file" field
+ * of the stored DHCPACK packet, whence it will be returned via any
+ * subsequent calls to pxenv_get_cached_info().  Though this is
+ * essentially a bug in the Intel PXE implementation (not, for once,
+ * in the specification!), it is a bug that Microsoft relies upon, and
+ * so we implement this bug-for-bug compatibility by overwriting the
+ * filename stored DHCPACK packet with the filename passed in
+ * s_PXENV_TFTP_READ_FILE::FileName.

+
+	Description:	
+
+	This is just a little bit of code and data that can get prepended
+	to a ROM image in order to allow bootloaders to load the result
+	as if it were a Linux kernel image.
+
+	A real Linux kernel image consists of a one-sector boot loader
+	(to load the image from a floppy disk), followed a few sectors
+	of setup code, followed by the kernel code itself.  There's
+	a table in the first sector (starting at offset 497) that indicates
+	how many sectors of setup code follow the first sector and which
+	contains some other parameters that aren't interesting in this
+	case.
+
+	When a bootloader loads the sectors that comprise a kernel image,
+	it doesn't execute the code in the first sector (since that code
+	would try to load the image from a floppy disk.)  The code in the
+	first sector below doesn't expect to get executed (and prints an
+	error message if it ever -is- executed.)
+
+	We don't require much in the way of setup code.  Historically, the
+	Linux kernel required at least 4 sectors of setup code.
+	Therefore, at least 4 sectors must be present even though we don't
+	use them.

+ * This file defines libkir: an interface between external and

+ *
+ * libkir is written to avoid assuming that segments are anything

+/**
+ * @defgroup bigint_api Big Integer API
+ * @brief The bigint implementation as used by the axTLS project.
+ *
+ * The bigint library is for RSA encryption/decryption as well as signing.
+ * This code tries to minimise use of malloc/free by maintaining a small 
+ * cache. A bigint context may maintain state by being made "permanent". 
+ * It be be later released with a bi_depermanent() and bi_free() call.
+ *
+ * It supports the following reduction techniques:
+ * - Classical
+ * - Barrett
+ * - Montgomery
+ *
+ * It also implements the following:
+ * - Karatsuba multiplication
+ * - Squaring
+ * - Sliding window exponentiation
+ * - Chinese Remainder Theorem (implemented in rsa.c).
+ *
+ * All the algorithms used are pretty standard, and designed for different
+ * data bus sizes. Negative numbers are not dealt with at all, so a subtraction
+ * may need to be tested for negativity.
+ *
+ * This library steals some ideas from Jef Poskanzer
+ * <http://cs.marlboro.edu/term/cs-fall02/algorithms/crypto/RSA/bigint>
+ * and GMP <http://www.swox.com/gmp>. It gets most of its implementation
+ * detail from "The Handbook of Applied Cryptography"
+ * <http://www.cacr.math.uwaterloo.ca/hac/about/chap14.pdf>

+/** @page build_sys Build system
+
+@section overview Overview
+
+Building an Etherboot image consists of three stages:
+
+  -# @ref compilation : Compiling all the source files into object files
+  -# @ref linking : Linking a particular image from selected object files
+  -# @ref finalisation : Producing the final output binary
+
+Though this is a remarkably complex process, it is important to note
+that it all happens automatically.  Whatever state your build tree is
+in, you can always type, for example
+
+@code
+
+	make bin/rtl8139.dsk
+
+@endcode
+
+and know that you will get a floppy disk image with an RTL8139 driver
+built from the current sources.
+
+@section compilation Compilation
+
+@subsection comp_overview Overview
+
+Each source file (a @c .c or a @c .S file) is compiled into a @c .o
+file in the @c bin/ directory.  Etherboot makes minimal use of
+conditional compilation (see @ref ifdef_harmful), and so you will find
+that all objects get built, even the objects that correspond to
+features that you are not intending to include in your image.  For
+example, all network card drivers will be compiled even if you are
+just building a ROM for a 3c509 card.  This is a deliberate design
+decision; please do @b not attempt to "fix" the build system to avoid
+doing this.
+
+Source files are defined to be any @c .c or @c .S files found in a
+directory listed in the Makefile variable #SRCDIRS.  You therefore do
+@b not need to edit the Makefile just because you have added a new
+source file (although you will need to edit the Makefile if you have
+added a new source directory).  To see a list of all source
+directories and source files that the build system currently knows
+about, you can use the commands
+
+@code
+
+	make srcdirs
+	make srcs
+
+@endcode
+
+Rules for compiling @c .c and @c .S files are defined in the Makefile
+variables #RULE_c and #RULE_S.  Makefile rules are automatically
+generated for each source file using these rules.  The generated rules
+can be found in the @c .d file corresponding to each source file;
+these are located in <tt>bin/deps/</tt>.  For example, the rules
+generated for <tt>drivers/net/rtl8139.c</tt> can be found in
+<tt>bin/deps/drivers/net/rtl8139.c.d</tt>.  These rules allow you to
+type, for example
+
+@code
+
+	make bin/rtl8139.o
+
+@endcode
+
+and have <tt>rtl8139.o</tt> be built from
+<tt>drivers/net/rtl8139.c</tt> using the generic rule #RULE_c for
+compiling @c .c files.
+
+You can see the full list of object files that will be built using
+
+@code
+
+	make bobjs
+
+@endcode
+
+@subsection comp_ar After compilation
+
+Once all objects have been compiled, they will be collected into a
+build library ("blib") in <tt>bin/blib.a</tt>.
+
+@subsection comp_custom Customising compilation
+
+The Makefile rules for a particular object can be customised to a
+certain extent by defining the Makefile variable CFLAGS_@<object@>.
+For example, if you were to set
+
+@code
+
+	CFLAGS_rtl8139 = -DFOO
+
+@endcode
+
+then <tt>bin/rtl8139.o</tt> would be compiled with the additional
+flags <tt>-DFOO</tt>.  To see the flags that will be used when
+compiling a particular object, you can use e.g.
+
+@code
+
+	make bin/rtl8139.flags
+
+@endcode
+
+If you need more flexibility than the CFLAGS_@<object@> mechanism
+provides, then you can exclude source files from the automatic rule
+generation process by listing them in the Makefile variable
+#NON_AUTO_SRCS.  The command
+
+@code
+
+	make autosrcs
+
+@endcode
+
+will show you which files are currently part of the automatic rule
+generation process.
+
+@subsection comp_multiobj Multiple objects
+
+A single source file can be used to generate multiple object files.
+This is used, for example, to generate the decompressing and the
+non-decompressing prefixes from the same source files.
+
+By default, a single object will be built from each source file.  To
+override the list of objects for a source file, you can define the
+Makefile variable OBJS_@<object@>.  For example, the
+<tt>arch/i386/prefix/dskprefix.S</tt> source file is built into two
+objects, <tt>bin/dskprefix.o</tt> and <tt>zdskprefix.o</tt> by
+defining the Makefile variable
+
+@code
+
+	OBJS_dskprefix = dskprefix zdskprefix
+
+@endcode
+
+Since there would be little point in building two identical objects,
+customised compilation flags (see @ref comp_custom) are defined as
+
+@code
+
+	CFLAGS_zdskprefix = -DCOMPRESS
+
+@endcode
+
+Thus, <tt>arch/i386/prefix/dskprefix.S</tt> is built into @c
+dskprefix.o using the normal set of flags, and into @c zdskprefix.o
+using the normal set of flags plus <tt>-DCOMPRESS</tt>.
+
+@subsection comp_debug Special debugging targets
+
+In addition to the basic rules #RULE_c and #RULE_S for compiling
+source files into object files, there are various other rules that can
+be useful for debugging.
+
+@subsubsection comp_debug_c_to_c Preprocessed C
+
+You can see the results of preprocessing a @c .c file (including the
+per-object flags defined via CFLAGS_@<object@> if applicable) using
+e.g.
+
+@code
+
+	make bin/rtl8139.c
+
+@endcode
+
+and examining the resulting file (<tt>bin/rtl8139.c</tt> in this
+case).
+
+@subsubsection comp_debug_x_to_s Assembler
+
+You can see the results of assembling a @c .c file, or of
+preprocessing a @c .S file, using e.g.
+
+@code
+
+	make bin/rtl8139.s
+	make bin/zdskprefix.s
+
+@endcode
+
+@subsubsection comp_debug_dbg Debugging-enabled targets
+
+You can build targets with debug messages (DBG()) enabled using e.g.
+
+@code
+
+	make bin/rtl8139.dbg.o
+	make bin/rtl8139.dbg2.o
+
+@endcode
+
+You will probably not need to use these targets directly, since a
+mechanism exists to select debugging levels at build time; see @ref
+debug.
+
+@section linking Linking
+
+@subsection link_overview Overview
+
+Etherboot is designed to be small and extremely customisable.  This is
+achieved by linking in only the features that are really wanted in any
+particular build.
+
+There are two places from which the list of desired features is
+obtained:
+
+  -# @ref link_config_h
+  -# @ref link_cmdline
+
+@subsection link_config_h config.h
+
+The config.h file is used to define global build options that are
+likely to apply to all images that you build, such as the console
+types, supported download protocols etc.  See the documentation for
+config.h for more details.
+
+@subsection link_cmdline The make command line
+
+When you type a command such as
+
+@code
+
+	make bin/dfe538.zrom
+
+@endcode
+
+it is used to derive the following information:
+
+   - We are building a compressed ROM image
+   - The DFE538 is a PCI NIC, so we need the decompressing PCI ROM prefix
+   - The PCI IDs for the DFE538 are 1186:1300
+   - The DFE538 is an rtl8139-based card, therefore we need the rtl8139 driver
+
+You can see this process in action using the command
+
+@code
+
+	make bin/dfe538.zrom.info
+
+@endcode
+
+which will print
+
+@code
+
+	Elements             : dfe538
+	Prefix               : zrom
+	Drivers              : rtl8139
+	ROM name             : dfe538
+	Media                : rom
+
+	ROM type             : pci
+	PCI vendor           : 0x1186
+	PCI device           : 0x1300
+
+	LD driver symbols    : obj_rtl8139
+	LD prefix symbols    : obj_zpciprefix
+	LD ID symbols        : pci_vendor_id=0x1186 pci_device_id=0x1300
+
+	LD target flags      :  -u obj_zpciprefix --defsym check_obj_zpciprefix=obj_zpciprefix   -u obj_rtl8139 --defsym check_obj_rtl8139=obj_rtl8139   -u obj_config --defsym check_obj_config=obj_config  --defsym pci_vendor_id=0x1186 --defsym pci_device_id=0x1300
+
+@endcode
+
+This should be interpreted as follows:
+
+@code
+
+	Elements             : dfe538
+	Prefix               : zrom
+
+@endcode
+
+"Elements" is the list of components preceding the first dot in the
+target name.  "Prefix" is the component following the first dot in the
+target name.  (It's called a "prefix" because the code that makes it a
+@c .zrom (rather than a @c .dsk, @c .zpxe or any other type of target)
+usually ends up at the start of the resulting binary image.)
+
+@code
+
+	Drivers              : rtl8139
+
+@endcode
+
+"Drivers" is the list of drivers corresponding to the "Elements".
+Most drivers support several network cards.  The PCI_ROM() and
+ISA_ROM() macros are used in the driver source files to list the cards
+that a particular driver can support.
+
+@code
+
+	ROM name             : dfe538
+
+@endcode
+
+"ROM name" is the first element in the "Elements" list.  It is used to
+select the PCI IDs for a PCI ROM.
+
+@code
+
+	Media                : rom
+
+@endcode
+
+"Media" is the "Prefix" minus the leading @c z, if any.
+
+@code
+
+	ROM type             : pci
+	PCI vendor           : 0x1186
+	PCI device           : 0x1300
+
+@endcode
+
+These are derived from the "ROM name" and the PCI_ROM() or ISA_ROM()
+macros in the driver source files.
+
+@code
+
+	LD driver symbols    : obj_rtl8139
+	LD prefix symbols    : obj_zpciprefix
+
+@endcode
+
+This is the interesting part.  At this point, we have established that
+we need the rtl8139 driver (i.e. @c rtl8139.o) and the decompressing
+PCI prefix (i.e. @c zpciprefix.o).  Our build system (via the
+compiler.h header file) arranges that every object exports a symbol
+obj_@<object@>; this can be seen by e.g.
+
+@code
+
+	objdump -t bin/rtl8139.o
+
+@endcode
+
+which will show the line
+
+@code
+
+	00000000 g       *ABS*  00000000 obj_rtl8139
+
+@endcode
+
+By instructing the linker that we need the symbols @c obj_rtl8139 and
+@c obj_zpciprefix, we can therefore ensure that these two objects are
+included in our build.  (The linker will also include any objects that
+these two objects require, since that's the whole purpose of the
+linker.)
+
+In a similar way, we always instruct the linker that we need the
+symbol @c obj_config, in order to include the object @c config.o.  @c
+config.o is used to drag in the objects that were specified via
+config.h; see @ref link_config_h.
+
+@code
+
+	LD target flags      :  -u obj_zpciprefix --defsym check_obj_zpciprefix=obj_zpciprefix   -u obj_rtl8139 --defsym check_obj_rtl8139=obj_rtl8139   -u obj_config --defsym check_obj_config=obj_config  --defsym pci_vendor_id=0x1186 --defsym pci_device_id=0x1300
+
+@endcode
+
+These are the flags that we pass to the linker in order to include the
+objects that we want in our build, and to check that they really get
+included.  (This latter check is needed to work around what seems to
+be a bug in @c ld).
+
+The linker does its job of linking all the required objects together
+into a coherent build.  The best way to see what is happening is to
+look at one of the resulting linker maps; try, for example
+
+@code
+
+	make bin/dfe538.dsk.map
+
+@endcode
+
+The linker map includes, amongst others:
+
+  - A list of which objects are included in the build, and why.
+  - The results of processing the linker script, line-by-line.
+  - A complete symbol table of the resulting build.
+
+It is worth spending time examining the linker map to see how an
+Etherboot image is assembled.
+
+Whatever format is selected, the Etherboot image is built into an ELF
+file, simply because this is the default format used by @c ld.
+
+@section finalisation Finalisation
+
+@subsection final_overview Overview
+
+The ELF file resulting from @ref linking "linking" needs to be
+converted into the final binary image.  Usually, this is just a case
+of running
+
+@code
+
+	objcopy -O binary <elf file> <output file>
+
+@endcode
+
+to convert the ELF file into a raw binary image.  Certain image
+formats require special additional treatment.
+
+@subsection final_rom ROM images
+
+ROM images must be rounded up to a suitable ROM size (e.g. 16kB or
+32kB), and certain header information such as checksums needs to be
+filled in.  This is done by the @c makerom.pl program.

+3c515.c -- 3COM 3C515 Fast Etherlink ISA 10/100BASE-TX driver for etherboot
+Copyright (C) 2002 Timothy Legge <tlegge@rogers.com>
+
+This driver is for the 3COM 3C515 Fast Etherlink ISA 10/100BASE-TX
+
+REVISION HISTORY:
+================
+v0.10 4-17-2002       TJL       Initial implementation.
+v0.11 4-17-2002       TJL       Cleanup of the code
+v0.12 4-26-2002       TJL       Added ISA Plug and Play for Non-PNP Bioses
+v0.13 3-31-2003	      TJL	Fixed issue 1 and 2 below
+
+The driver is heavily based on the work of others are referenced in the 3c515.c file.
+
+ISA Plug and Play (ISAPNP) support has been added for Non-PNP Bioses.  The ISAPNP code requires the defination of ISA_PNP as:
+
+#define ISA_PNP
+
+Issues:
+=======
+1) RESOLVED - When ISAPNP is defined, the etherboot probe is unable to find the card during the first probe.  This is true even though the ISA PNP code actually found and activated the driver.
+
+2) RESOLVED - When ISA_PNP is defined, the etherboot probe finds the incorrect MAC address for the card. However, when the linux kernel boots and loads the linux 3c515 driver the correct MAC address is found. This means that with ISA_PNP defined, you require both MAC addresses defined in the /etc/dhcpd.conf file.  The first MAC address allows the driver to load the LTSP Linux kernel.  The second allows the Linux dhclient to resolve its IP address.
+
+3) Although the ISA PNP docs specify that the IRQ, DMA and IO Address needs to be assigned to the card before it is activated, Etherboot does not seem to care.  Therefore the code does not assign the card with these values.
+
+If you can help address any of thse issues, please feel free.

+ * v1.00pre1	2-11-1998	GRB	Got prom boot issue fixed.
+ * v2.0		9-24-1999	SCS	Modified for 3c905 (from 3c905b code)
+ *					Re-wrote poll and transmit for

+/* Command style register access
+
+Registers CMD0, CMD2, CMD3,CMD7 and INTEN0 uses a write access technique called command style access. It allows the write to selected bits of this register without altering the bits that are not selected. Command style registers are divided into 4 bytes that can be written independently. Higher order bit of each byte is the  value bit that specifies the value that will be written into the selected bits of register. 
+
+eg., if the value 10011010b is written into the least significant byte of a command style register, bits 1,3 and 4 of the register will be set to 1, and the other bits will not be altered. If the value 00011010b is written into the same byte, bits 1,3 and 4 will be cleared to 0 and the other bits will not be altered.

+ * Modulation for Atheros' Turbo G and Turbo A, its supposed to provide a
+ * throughput transmission speed up to 40Mbit/s-60Mbit/s at a 108Mbit/s
+ * signaling rate achieved through the bonding of two 54Mbit/s 802.11g
+ * channels. To use this feature your Access Point must also suport it.
+ * There is also a distinction between "static" and "dynamic" turbo modes:
+ *
+ * - Static: is the dumb version: devices set to this mode stick to it until
+ *     the mode is turned off.
+ * - Dynamic: is the intelligent version, the network decides itself if it
+ *     is ok to use turbo. As soon as traffic is detected on adjacent channels
+ *     (which would get used in turbo mode), or when a non-turbo station joins
+ *     the network, turbo mode won't be used until the situation changes again.
+ *     Dynamic mode is achieved by Atheros' Adaptive Radio (AR) feature which
+ *     monitors the used radio band in order to decide whether turbo mode may
+ *     be used or not.
+ *
+ * This article claims Super G sticks to bonding of channels 5 and 6 for
+ * USA:
+ *
+ * http://www.pcworld.com/article/id,113428-page,1/article.html
+ *
+ * The channel bonding seems to be driver specific though. In addition to
+ * deciding what channels will be used, these "Turbo" modes are accomplished
+ * by also enabling the following features:
+ *
+ * - Bursting: allows multiple frames to be sent at once, rather than pausing
+ *     after each frame. Bursting is a standards-compliant feature that can be
+ *     used with any Access Point.
+ * - Fast frames: increases the amount of information that can be sent per
+ *     frame, also resulting in a reduction of transmission overhead. It is a
+ *     proprietary feature that needs to be supported by the Access Point.
+ * - Compression: data frames are compressed in real time using a Lempel Ziv
+ *     algorithm. This is done transparently. Once this feature is enabled,
+ *     compression and decompression takes place inside the chipset, without
+ *     putting additional load on the host CPU.

+ * enum ath5k_int - Hardware interrupt masks helpers
+ *
+ * @AR5K_INT_RX: mask to identify received frame interrupts, of type
+ * 	AR5K_ISR_RXOK or AR5K_ISR_RXERR
+ * @AR5K_INT_RXDESC: Request RX descriptor/Read RX descriptor (?)
+ * @AR5K_INT_RXNOFRM: No frame received (?)
+ * @AR5K_INT_RXEOL: received End Of List for VEOL (Virtual End Of List). The
+ * 	Queue Control Unit (QCU) signals an EOL interrupt only if a descriptor's
+ * 	LinkPtr is NULL. For more details, refer to:
+ * 	http://www.freepatentsonline.com/20030225739.html
+ * @AR5K_INT_RXORN: Indicates we got RX overrun (eg. no more descriptors).
+ * 	Note that Rx overrun is not always fatal, on some chips we can continue
+ * 	operation without reseting the card, that's why int_fatal is not
+ * 	common for all chips.
+ * @AR5K_INT_TX: mask to identify received frame interrupts, of type
+ * 	AR5K_ISR_TXOK or AR5K_ISR_TXERR
+ * @AR5K_INT_TXDESC: Request TX descriptor/Read TX status descriptor (?)
+ * @AR5K_INT_TXURN: received when we should increase the TX trigger threshold
+ * 	We currently do increments on interrupt by
+ * 	(AR5K_TUNE_MAX_TX_FIFO_THRES - current_trigger_level) / 2
+ * @AR5K_INT_MIB: Indicates the Management Information Base counters should be
+ * 	checked. We should do this with ath5k_hw_update_mib_counters() but
+ * 	it seems we should also then do some noise immunity work.
+ * @AR5K_INT_RXPHY: RX PHY Error
+ * @AR5K_INT_RXKCM: RX Key cache miss
+ * @AR5K_INT_SWBA: SoftWare Beacon Alert - indicates its time to send a
+ * 	beacon that must be handled in software. The alternative is if you
+ * 	have VEOL support, in that case you let the hardware deal with things.
+ * @AR5K_INT_BMISS: If in STA mode this indicates we have stopped seeing
+ * 	beacons from the AP have associated with, we should probably try to
+ * 	reassociate. When in IBSS mode this might mean we have not received
+ * 	any beacons from any local stations. Note that every station in an
+ * 	IBSS schedules to send beacons at the Target Beacon Transmission Time
+ * 	(TBTT) with a random backoff.
+ * @AR5K_INT_BNR: Beacon Not Ready interrupt - ??
+ * @AR5K_INT_GPIO: GPIO interrupt is used for RF Kill, disabled for now
+ * 	until properly handled
+ * @AR5K_INT_FATAL: Fatal errors were encountered, typically caused by DMA
+ * 	errors. These types of errors we can enable seem to be of type
+ * 	AR5K_SIMR2_MCABT, AR5K_SIMR2_SSERR and AR5K_SIMR2_DPERR.
+ * @AR5K_INT_GLOBAL: Used to clear and set the IER
+ * @AR5K_INT_NOCARD: signals the card has been removed
+ * @AR5K_INT_COMMON: common interrupts shared amogst MACs with the same
+ * 	bit value
+ *
+ * These are mapped to take advantage of some common bits
+ * between the MACs, to be able to set intr properties
+ * easier. Some of them are not used yet inside hw.c. Most map
+ * to the respective hw interrupt value as they are common amogst different
+ * MACs.

+ * BSSID masking is a method used by AR5212 and newer hardware to inform PCU

+ * to decide which packets to ACK. In station mode and AP mode with a single
+ * BSS every bit matters since we lock to only one BSS. In AP mode with

+ * accept frames for all BSSes and so we tweak some bits of our mac address
+ * in order to have multiple BSSes.
+ *
+ * NOTE: This is a simple filter and does *not* filter out all
+ * relevant frames. Some frames that are not for us might get ACKed from us
+ * by PCU because they just match the mask.
+ *
+ * When handling multiple BSSes you can get the BSSID mask by computing the
+ * set of  ~ ( MAC XOR BSSID ) for all bssids we handle.
+ *
+ * When you do this you are essentially computing the common bits of all your
+ * BSSes. Later it is assumed the harware will "and" (&) the BSSID mask with
+ * the MAC address to obtain the relevant bits and compare the result with
+ * (frame's BSSID & mask) to see if they match.
+ */

+ * Simple example: on your card you have have two BSSes you have created with
+ * BSSID-01 and BSSID-02. Lets assume BSSID-01 will not use the MAC address.
+ * There is another BSSID-03 but you are not part of it. For simplicity's sake,
+ * assuming only 4 bits for a mac address and for BSSIDs you can then have:
+ *
+ *                  \
+ * MAC:                0001 |
+ * BSSID-01:   0100 | --> Belongs to us
+ * BSSID-02:   1001 |
+ *                  /
+ * -------------------
+ * BSSID-03:   0110  | --> External
+ * -------------------
+ *
+ * Our bssid_mask would then be:
+ *
+ *             On loop iteration for BSSID-01:
+ *             ~(0001 ^ 0100)  -> ~(0101)
+ *                             ->   1010
+ *             bssid_mask      =    1010
+ *
+ *             On loop iteration for BSSID-02:
+ *             bssid_mask &= ~(0001   ^   1001)
+ *             bssid_mask =   (1010)  & ~(0001 ^ 1001)
+ *             bssid_mask =   (1010)  & ~(1001)
+ *             bssid_mask =   (1010)  &  (0110)
+ *             bssid_mask =   0010
+ *
+ * A bssid_mask of 0010 means "only pay attention to the second least
+ * significant bit". This is because its the only bit common
+ * amongst the MAC and all BSSIDs we support. To findout what the real
+ * common bit is we can simply "&" the bssid_mask now with any BSSID we have
+ * or our MAC address (we assume the hardware uses the MAC address).
+ *
+ * Now, suppose there's an incoming frame for BSSID-03:
+ *
+ * IFRAME-01:  0110
+ *
+ * An easy eye-inspeciton of this already should tell you that this frame
+ * will not pass our check. This is beacuse the bssid_mask tells the
+ * hardware to only look at the second least significant bit and the
+ * common bit amongst the MAC and BSSIDs is 0, this frame has the 2nd LSB
+ * as 1, which does not match 0.
+ *
+ * So with IFRAME-01 we *assume* the hardware will do:
+ *
+ *     allow = (IFRAME-01 & bssid_mask) == (bssid_mask & MAC) ? 1 : 0;
+ *  --> allow = (0110 & 0010) == (0010 & 0001) ? 1 : 0;
+ *  --> allow = (0010) == 0000 ? 1 : 0;
+ *  --> allow = 0
+ *
+ *  Lets now test a frame that should work:
+ *
+ * IFRAME-02:  0001 (we should allow)
+ *
+ *     allow = (0001 & 1010) == 1010
+ *
+ *     allow = (IFRAME-02 & bssid_mask) == (bssid_mask & MAC) ? 1 : 0;
+ *  --> allow = (0001 & 0010) ==  (0010 & 0001) ? 1 :0;
+ *  --> allow = (0010) == (0010)
+ *  --> allow = 1
+ *
+ * Other examples:
+ *
+ * IFRAME-03:  0100 --> allowed
+ * IFRAME-04:  1001 --> allowed
+ * IFRAME-05:  1101 --> allowed but its not for us!!!

+ * There are some special registers on the RF chip
+ * that control various operation settings related mostly to
+ * the analog parts (channel, gain adjustment etc).
+ *
+ * We don't write on those registers directly but
+ * we send a data packet on the chip, using a special register,
+ * that holds all the settings we need. After we 've sent the
+ * data packet, we write on another special register to notify hw
+ * to apply the settings. This is done so that control registers
+ * can be dynamicaly programmed during operation and the settings
+ * are applied faster on the hw.
+ *
+ * We call each data packet an "RF Bank" and all the data we write
+ * (all RF Banks) "RF Buffer". This file holds initial RF Buffer
+ * data for the different RF chips, and various info to match RF
+ * Buffer offsets with specific RF registers so that we can access
+ * them. We tweak these settings on rfregs_init function.

+  ChangeLog:
+
+  Thu Dec 6 22:40:00 1996  Markus Gutschke  <gutschk@math.uni-muenster.de>
+
+  * disabled all "advanced" features; this should make the code more reliable
+
+  * reorganized the reset function
+
+  * always reset the address port, so that autoprobing will continue working
+
+  * some cosmetic changes
+
+  * 2.5
+
+  Thu Dec 5 21:00:00 1996  Markus Gutschke  <gutschk@math.uni-muenster.de>
+
+  * tested the code against a CS8900 card
+
+  * lots of minor bug fixes and adjustments
+
+  * this is the first release, that actually works! it still requires some
+    changes in order to be more tolerant to different environments
+
+  * 4
+
+  Fri Nov 22 23:00:00 1996  Markus Gutschke  <gutschk@math.uni-muenster.de>
+
+  * read the manuals for the CS89x0 chipsets and took note of all the
+    changes that will be neccessary in order to adapt Russel Nelson's code
+    to the requirements of a BOOT-Prom
+
+  * 6
+
+  Thu Nov 19 22:00:00 1996  Markus Gutschke  <gutschk@math.uni-muenster.de>
+
+  * Synched with Russel Nelson's current code (v1.00)
+
+  * 2
+
+  Thu Nov 12 18:00:00 1996  Markus Gutschke  <gutschk@math.uni-muenster.de>
+
+  * Cleaned up some of the code and tried to optimize the code size.
+
+  * 1.5
+
+  Sun Nov 10 16:30:00 1996  Markus Gutschke  <gutschk@math.uni-muenster.de>
+
+  * First experimental release. This code compiles fine, but I
+  have no way of testing whether it actually works.
+
+  * I did not (yet) bother to make the code 16bit aware, so for
+  the time being, it will only work for Etherboot/32.

+
+    This driver is written for the Digital Equipment Corporation series
+    of DEPCA and EtherWORKS ethernet cards:
+
+        DEPCA       (the original)
+    	DE100
+    	DE101
+	DE200 Turbo
+	DE201 Turbo
+	DE202 Turbo (TP BNC)
+	DE210
+	DE422       (EISA)
+
+    The  driver has been tested on DE100, DE200 and DE202 cards  in  a
+    relatively busy network. The DE422 has been tested a little.
+
+    This  driver will NOT work   for the DE203,  DE204  and DE205 series  of
+    cards,  since they have  a  new custom ASIC in   place of the AMD  LANCE
+    chip.  See the 'ewrk3.c'   driver in the  Linux  source tree for running
+    those cards.
+
+    I have benchmarked the driver with a  DE100 at 595kB/s to (542kB/s from)
+    a DECstation 5000/200.

+
+    The  driver was originally based  on   the 'lance.c' driver from  Donald
+    Becker   which  is included with  the  standard  driver distribution for
+    linux.  V0.4  is  a complete  re-write  with only  the kernel  interface
+    remaining from the original code.

+
+    Peter Bauer's depca.c (V0.5) was referred to when debugging V0.1 of this
+    driver.
+
+    The original DEPCA  card requires that the  ethernet ROM address counter
+    be enabled to count and has an 8 bit NICSR.  The ROM counter enabling is
+    only  done when a  0x08 is read as the  first address octet (to minimise
+    the chances  of writing over some  other hardware's  I/O register).  The
+    NICSR accesses   have been changed  to  byte accesses  for all the cards
+    supported by this driver, since there is only one  useful bit in the MSB
+    (remote boot timeout) and it  is not used.  Also, there  is a maximum of
+    only 48kB network  RAM for this  card.  My thanks  to Torbjorn Lindh for
+    help debugging all this (and holding my feet to  the fire until I got it
+    right).
+
+    The DE200  series  boards have  on-board 64kB  RAM for  use  as a shared
+    memory network  buffer. Only the DE100  cards make use  of a  2kB buffer
+    mode which has not  been implemented in  this driver (only the 32kB  and
+    64kB modes are supported [16kB/48kB for the original DEPCA]).
+
+    At the most only 2 DEPCA cards can  be supported on  the ISA bus because
+    there is only provision  for two I/O base addresses  on each card (0x300
+    and 0x200). The I/O address is detected by searching for a byte sequence
+    in the Ethernet station address PROM at the expected I/O address for the
+    Ethernet  PROM.   The shared memory  base   address  is 'autoprobed'  by
+    looking  for the self  test PROM  and detecting the  card name.   When a
+    second  DEPCA is  detected,  information  is   placed in the   base_addr
+    variable of the  next device structure (which  is created if necessary),
+    thus  enabling ethif_probe  initialization  for the device.  More than 2
+    EISA cards can  be  supported, but  care will  be  needed assigning  the
+    shared memory to ensure that each slot has the  correct IRQ, I/O address
+    and shared memory address assigned.
+
+    ************************************************************************
+
+    NOTE: If you are using two  ISA DEPCAs, it is  important that you assign
+    the base memory addresses correctly.   The  driver autoprobes I/O  0x300
+    then 0x200.  The  base memory address for  the first device must be less
+    than that of the second so that the auto probe will correctly assign the
+    I/O and memory addresses on the same card.  I can't think of a way to do
+    this unambiguously at the moment, since there is nothing on the cards to
+    tie I/O and memory information together.
+
+    I am unable  to  test  2 cards   together for now,    so this  code   is
+    unchecked. All reports, good or bad, are welcome.
+
+    ************************************************************************
+
+    The board IRQ   setting must be  at an  unused IRQ which  is auto-probed
+    using Donald Becker's autoprobe routines. DEPCA and DE100 board IRQs are
+    {2,3,4,5,7}, whereas the  DE200 is at {5,9,10,11,15}.  Note that IRQ2 is
+    really IRQ9 in machines with 16 IRQ lines.
+
+    No 16MB memory  limitation should exist with this  driver as DMA is  not
+    used and the common memory area is in low memory on the network card (my
+    current system has 20MB and I've not had problems yet).
+
+    The ability to load this driver as a loadable module has been added. To
+    utilise this ability, you have to do <8 things:
+
+    0) have a copy of the loadable modules code installed on your system.
+    1) copy depca.c from the  /linux/drivers/net directory to your favourite
+    temporary directory.
+    2) if you wish, edit the  source code near  line 1530 to reflect the I/O
+    address and IRQ you're using (see also 5).
+    3) compile  depca.c, but include -DMODULE in  the command line to ensure
+    that the correct bits are compiled (see end of source code).
+    4) if you are wanting to add a new  card, goto 5. Otherwise, recompile a
+    kernel with the depca configuration turned off and reboot.
+    5) insmod depca.o [irq=7] [io=0x200] [mem=0xd0000] [adapter_name=DE100]
+       [Alan Cox: Changed the code to allow command line irq/io assignments]
+       [Dave Davies: Changed the code to allow command line mem/name
+                                                                assignments]
+    6) run the net startup bits for your eth?? interface manually 
+    (usually /etc/rc.inet[12] at boot time). 
+    7) enjoy!
+
+    Note that autoprobing is not allowed in loadable modules - the system is
+    already up and running and you're messing with interrupts.
+
+    To unload a module, turn off the associated interface 
+    'ifconfig eth?? down' then 'rmmod depca'.
+
+    To assign a base memory address for the shared memory  when running as a
+    loadable module, see 5 above.  To include the adapter  name (if you have
+    no PROM  but know the card name)  also see 5  above. Note that this last
+    option  will not work  with kernel  built-in  depca's. 
+
+    The shared memory assignment for a loadable module  makes sense to avoid
+    the 'memory autoprobe' picking the wrong shared memory  (for the case of
+    2 depca's in a PC).
+
+    ************************************************************************
+    Support for MCA EtherWORKS cards added 11-3-98.
+    Verified to work with up to 2 DE212 cards in a system (although not
+      fully stress-tested).  
+
+    Currently known bugs/limitations:
+
+    Note:  with the MCA stuff as a module, it trusts the MCA configuration,
+           not the command line for IRQ and memory address.  You can
+           specify them if you want, but it will throw your values out.
+           You still have to pass the IO address it was configured as
+           though.

+/**************************************************************************
+Etherboot -  BOOTP/TFTP Bootstrap Program
+Intel EEPRO/10 NIC driver for Etherboot
+Adapted from Linux eepro.c from kernel 2.2.17
+
+This board accepts a 32 pin EEPROM (29C256), however a test with a
+27C010 shows that this EPROM also works in the socket, but it's not clear
+how repeatably. The two top address pins appear to be held low, thus
+the bottom 32kB of the 27C010 is visible in the CPU's address space.
+To be sure you could put 4 copies of the code in the 27C010, then
+it doesn't matter whether the extra lines are held low or high, just
+hopefully not floating as CMOS chips don't like floating inputs.
+
+Be careful with seating the EPROM as the socket on my board actually
+has 34 pins, the top row of 2 are not used.

+/*
+ * General Theory of Operation
+ *
+ * Initialization
+ *
+ * ifec_pci_probe() is called by gPXE during initialization. Typical NIC
+ * initialization is performed.  EEPROM data is read.
+ *
+ * Network Boot
+ *
+ * ifec_net_open() is called by gPXE before attempting to network boot from the
+ * card.  Here, the Command Unit & Receive Unit are initialized.  The tx & rx
+ * rings are setup.  The MAC address is programmed and the card is configured.
+ *
+ * Transmit
+ *
+ * ifec_net_transmit() enqueues a packet in the tx ring - active::tcbs[]  The tx
+ * ring is composed of TCBs linked to each other into a ring.  A tx request
+ * fills out the next available TCB with a pointer to the packet data.
+ * The last enqueued tx is always at active::tcb_head.  Thus, a tx request fills
+ * out the TCB following tcb_head.
+ * active::tcb_tail points to the TCB we're awaiting completion of.
+ * ifec_tx_process() checks tcb_tail, and once complete,
+ * blindly increments tcb_tail to the next ring TCB.
+ *
+ * Receive
+ *
+ * priv::rfds[] is an array of Receive Frame Descriptors. The RFDs are linked
+ * together to form a ring.
+ * ifec_net_poll() calls ifec_rx_process(), which checks the next RFD for
+ * data.  If we received a packet, we allocate a new io_buffer and copy the
+ * packet data into it. If alloc_iob() fails, we don't touch the RFD and try
+ * again on the next poll.
+ */
+
+/*
+ * Debugging levels:
+ *	- DBG() is for any errors, i.e. failed alloc_iob(), malloc_dma(),
+ *	  TX overflow, corrupted packets, ...
+ *	- DBG2() is for successful events, like packet received,
+ *	  packet transmitted, and other general notifications.
+ *	- DBGP() prints the name of each called function on entry

+ *
+ * Etherfabric bitfield access
+ *
+ * Etherfabric NICs make extensive use of bitfields up to 128 bits
+ * wide.  Since there is no native 128-bit datatype on most systems,
+ * and since 64-bit datatypes are inefficient on 32-bit systems and
+ * vice versa, we wrap accesses in a way that uses the most efficient
+ * datatype.
+ *
+ * The NICs are PCI devices and therefore little-endian.  Since most
+ * of the quantities that we deal with are DMAed to/from host memory,
+ * we define our datatypes (efab_oword_t, efab_qword_t and
+ * efab_dword_t) to be little-endian.
+ *
+ * In the less common case of using PIO for individual register
+ * writes, we construct the little-endian datatype in host memory and
+ * then use non-swapping equivalents of writel/writeq, rather than
+ * constructing a native-endian datatype and relying on the implicit
+ * byte-swapping done by writel/writeq.  (We use a similar strategy
+ * for register reads.)

+ * General Theory of Operation
+ *
+ * This is a minimal Myricom 10 gigabit Ethernet driver for network
+ * boot.
+ *
+ * Initialization
+ *
+ * myri10ge_pci_probe() is called by gPXE during initialization.
+ * Minimal NIC initialization is performed to minimize resources
+ * consumed when the driver is resident but unused.
+ *
+ * Network Boot
+ *
+ * myri10ge_net_open() is called by gPXE before attempting to network
+ * boot from the card.  Packet buffers are allocated and the NIC
+ * interface is initialized.
+ *
+ * Transmit
+ *
+ * myri10ge_net_transmit() enqueues frames for transmission by writing
+ * discriptors to the NIC's tx ring.  For simplicity and to avoid
+ * copies, we always have the NIC DMA up the packet.  The sent I/O
+ * buffer is released once the NIC signals myri10ge_interrupt_handler()
+ * that the send has completed.
+ *
+ * Receive
+ *
+ * Receives are posted to the NIC's receive ring.  The NIC fills a
+ * DMAable receive_completion ring with completion notifications.
+ * myri10ge_net_poll() polls for these receive notifications, posts
+ * replacement receive buffers to the NIC, and passes received frames
+ * to netdev_rx().
+ */
+
+/*
+ * Debugging levels:
+ *	- DBG() is for any errors, i.e. failed alloc_iob(), malloc_dma(),
+ *	  TX overflow, corrupted packets, ...
+ *	- DBG2() is for successful events, like packet received,
+ *	  packet transmitted, and other general notifications.
+ *	- DBGP() prints the name of each called function on entry

+/*
+  02 Jul 2007  Udayan Kumar	 1.2 ported the driver from etherboot to gPXE API.
+				     Fully rewritten,adapting the old driver.
+		      	      	     Added a circular buffer for transmit and receive.
+		                     transmit routine will not wait for transmission to finish.
+			             poll routine deals with it.
+  13 Dec 2003  Tim Legge         1.1 Enabled Multicast Support
+  29 May 2001  Marty Connor	 1.0 Initial Release. Tested with Netgear FA311 and FA312 boards

+
+/* CRB Root Command
+
+   A single set of crbs is used across all physical/virtual
+   functions for capability queries, initialization, and
+   context creation/destruction. 
+
+   There are 4 CRBS:
+       Command/Response CRB
+       Argument1 CRB
+       Argument2 CRB
+       Argument3 CRB
+       Signature CRB 
+
+       The cmd/rsp crb is always intiated by the host via
+       a command code and always responded by the card with
+       a response code. The cmd and rsp codes are disjoint.
+       The sequence of use is always CMD, RSP, CLEAR CMD.
+
+       The arguments are for passing in command specific
+       and response specific parameters/data. 
+
+       The signature is composed of a magic value, the
+       pci function id, and a command sequence id:
+          [7:0]  = pci function
+         [15:8]  = version
+         [31:16] = magic of 0xcafe
+
+       The pci function allows the card to take correct
+       action for the given particular commands. 
+       The firmware will attempt to detect
+       an errant driver that has died while holding  
+       the root crb hardware lock. Such an error condition
+       shows up as the cmd/rsp crb stuck in a non-clear state.
+
+   Interface Sequence:
+     Host always makes requests and firmware always responds.
+     Note that data field is always set prior to command field.

+  27 May 2006	mcb30@users.sourceforge.net (Michael Brown)
+     Rewrote to use the new net driver API, the updated PCI API, and
+     the generic three-wire serial device support for EEPROM access.
+
+  28 Dec 2002	ken_yap@users.sourceforge.net (Ken Yap)
+     Put in virt_to_bus calls to allow Etherboot relocation.
+
+  06 Apr 2001	ken_yap@users.sourceforge.net (Ken Yap)
+     Following email from Hyun-Joon Cha, added a disable routine, otherwise
+     NIC remains live and can crash the kernel later.
+
+  4 Feb 2000	espenlaub@informatik.uni-ulm.de (Klaus Espenlaub)
+     Shuffled things around, removed the leftovers from the 8129 support
+     that was in the Linux driver and added a bit more 8139 definitions.
+     Moved the 8K receive buffer to a fixed, available address outside the
+     0x98000-0x9ffff range.  This is a bit of a hack, but currently the only
+     way to make room for the Etherboot features that need substantial amounts
+     of code like the ANSI console support.  Currently the buffer is just below
+     0x10000, so this even conforms to the tagged boot image specification,
+     which reserves the ranges 0x00000-0x10000 and 0x98000-0xA0000.  My
+     interpretation of this "reserved" is that Etherboot may do whatever it
+     likes, as long as its environment is kept intact (like the BIOS
+     variables).  Hopefully fixed rtl_poll() once and for all.  The symptoms
+     were that if Etherboot was left at the boot menu for several minutes, the
+     first eth_poll failed.  Seems like I am the only person who does this.
+     First of all I fixed the debugging code and then set out for a long bug
+     hunting session.  It took me about a week full time work - poking around
+     various places in the driver, reading Don Becker's and Jeff Garzik's Linux
+     driver and even the FreeBSD driver (what a piece of crap!) - and
+     eventually spotted the nasty thing: the transmit routine was acknowledging
+     each and every interrupt pending, including the RxOverrun and RxFIFIOver
+     interrupts.  This confused the RTL8139 thoroughly.  It destroyed the
+     Rx ring contents by dumping the 2K FIFO contents right where we wanted to
+     get the next packet.  Oh well, what fun.
+
+  18 Jan 2000   mdc@etherboot.org (Marty Connor)
+     Drastically simplified error handling.  Basically, if any error
+     in transmission or reception occurs, the card is reset.
+     Also, pointed all transmit descriptors to the same buffer to
+     save buffer space.  This should decrease driver size and avoid
+     corruption because of exceeding 32K during runtime.
+
+  28 Jul 1999   (Matthias Meixner - meixner@rbg.informatik.tu-darmstadt.de)
+     rtl_poll was quite broken: it used the RxOK interrupt flag instead
+     of the RxBufferEmpty flag which often resulted in very bad
+     transmission performace - below 1kBytes/s.

+ * This driver intentionally does not support all the features of the
+ * original driver such as link fail-over and link management because
+ * those should be done at higher levels.

+/* There are two ways to manage the TX descriptors on the tigon3.
+ * Either the descriptors are in host DMA'able memory, or they
+ * exist only in the cards on-chip SRAM.  All 16 send bds are under
+ * the same mode, they may not be configured individually.
+ *
+ * The mode we use is controlled by TG3_FLAG_HOST_TXDS in tp->tg3_flags.
+ *
+ * To use host memory TX descriptors:
+ *	1) Set GRC_MODE_HOST_SENDBDS in GRC_MODE register.
+ *	   Make sure GRC_MODE_4X_NIC_SEND_RINGS is clear.
+ *	2) Allocate DMA'able memory.
+ *	3) In NIC_SRAM_SEND_RCB (of desired index) of on-chip SRAM:
+ *	   a) Set TG3_BDINFO_HOST_ADDR to DMA address of memory
+ *	      obtained in step 2
+ *	   b) Set TG3_BDINFO_NIC_ADDR to NIC_SRAM_TX_BUFFER_DESC.
+ *	   c) Set len field of TG3_BDINFO_MAXLEN_FLAGS to number
+ *            of TX descriptors.  Leave flags field clear.
+ *	4) Access TX descriptors via host memory.  The chip
+ *	   will refetch into local SRAM as needed when producer
+ *	   index mailboxes are updated.
+ *
+ * To use on-chip TX descriptors:
+ *	1) Set GRC_MODE_4X_NIC_SEND_RINGS in GRC_MODE register.
+ *	   Make sure GRC_MODE_HOST_SENDBDS is clear.
+ *	2) In NIC_SRAM_SEND_RCB (of desired index) of on-chip SRAM:
+ *	   a) Set TG3_BDINFO_HOST_ADDR to zero.
+ *	   b) Set TG3_BDINFO_NIC_ADDR to NIC_SRAM_TX_BUFFER_DESC
+ *	   c) TG3_BDINFO_MAXLEN_FLAGS is don't care.
+ *	3) Access TX descriptors directly in on-chip SRAM
+ *	   using normal {read,write}l().  (and not using
+ *         pointer dereferencing of ioremap()'d memory like
+ *	   the broken Broadcom driver does)
+ *
+ * Note that BDINFO_FLAGS_DISABLED should be set in the flags field of
+ * TG3_BDINFO_MAXLEN_FLAGS of all unused SEND_RCB indices.

+
+  This software may be used and distributed according to the terms

+
+  As of April 2001 this driver should support most tulip cards that 
+  the Linux tulip driver supports because Donald Becker's Linux media 
+  detection code is now included.
+
+  Based on Ken Yap's Tulip Etherboot Driver and Donald Becker's
+  Linux Tulip Driver. Supports N-Way speed auto-configuration on
+  MX98715, MX98715A and MX98725. Support inexpensive PCI 10/100 cards
+  based on the Macronix MX987x5 chip, such as the SOHOware Fast
+  model SFA110A, and the LinkSYS model LNE100TX. The NetGear
+  model FA310X, based on the LC82C168 chip is supported.
+  The TRENDnet TE100-PCIA NIC which uses a genuine Intel 21143-PD
+  chipset is supported. Also, Davicom DM9102's.
+
+  Documentation and source code used:
+  Source for Etherboot driver at
+  http://etherboot.sourceforge.net/
+  MX98715A Data Sheet and MX98715A Application Note
+  on http://www.macronix.com/  (PDF format files)
+  Source for Linux tulip driver at
+  http://cesdis.gsfc.nasa.gov/linux/drivers/tulip.html
+
+  Adapted by Ken Yap from
+  FreeBSD netboot DEC 21143 driver
+  Author: David Sharp
+  date: Nov/98
+
+  Some code fragments were taken from verious places, Ken Yap's
+  etherboot, FreeBSD's if_de.c, and various Linux related files.
+  DEC's manuals for the 21143 and SROM format were very helpful.
+  The Linux de driver development page has a number of links to
+  useful related information.  Have a look at:

+  08 Feb 2005  Ramesh Chander chhabaramesh at yahoo.co.in added table entries
+               for SGThomson STE10/100A
+  07 Sep 2003  timlegge	Multicast Support Added
+  11 Apr 2001  mdc     [patch to etherboot 4.7.24]
+     Major rewrite to include Linux tulip driver media detection
+     code.  This driver should support a lot more cards now.
+  16 Jul 2000  mdc     0.75b11
+     Added support for ADMtek 0985 Centaur-P, a "Comet" tulip clone
+     which is used on the LinkSYS LNE100TX v4.x cards.  We already
+     support LNE100TX v2.0 cards, which use a different controller.
+  04 Jul 2000   jam     ?
+     Added test of status after receiving a packet from the card.
+     Also uncommented the tulip_disable routine.  Stray packets
+     seemed to be causing problems.
+  27 Apr 2000   njl     ?
+  29 Feb 2000   mdc     0.75b7
+     Increased reset delay to 3 seconds because Macronix cards seem to
+     need more reset time before card comes back to a usable state.
+  26 Feb 2000   mdc     0.75b6
+     Added a 1 second delay after initializing the transmitter because
+     some cards seem to need the time or they drop the first packet 
+     transmitted.
+  23 Feb 2000   mdc     0.75b5
+     removed udelay code and used currticks() for more reliable delay
+     code in reset pause and sanity timeouts.  Added function prototypes
+     and TX debugging code.
+  21 Feb 2000   mdc     patch to Etherboot 4.4.3
+     Incorporated patches from Bob Edwards and Paul Mackerras of 
+     Linuxcare's OZLabs to deal with inefficiencies in tulip_transmit
+     and udelay.  We now wait for packet transmission to complete
+     (or sanity timeout).
+  04 Feb 2000   Robert.Edwards@anu.edu.au patch to Etherboot 4.4.2
+     patch to tulip.c that implements the automatic selection of the MII
+     interface on cards using the Intel/DEC 21143 reference design, in
+     particular, the TRENDnet TE100-PCIA NIC which uses a genuine Intel
+     21143-PD chipset.
+  11 Jan 2000   mdc     0.75b4
+     Added support for NetGear FA310TX card based on the LC82C168
+     chip.  This should also support Lite-On LC82C168 boards.
+     Added simple MII support. Re-arranged code to better modularize
+     initializations.
+  04 Dec 1999   mdc     0.75b3
+     Added preliminary support for LNE100TX PCI cards.  Should work for
+     PNIC2 cards. No MII support, but single interface (RJ45) tulip
+     cards seem to not care.
+  03 Dec 1999   mdc     0.75b2
+     Renamed from mx987x5 to tulip, merged in original tulip init code
+     from tulip.c to support other tulip compatible cards.
+  02 Dec 1999   mdc     0.75b1
+     Released Beta MX987x5 Driver for code review and testing to netboot
+     and thinguin mailing lists.

+
+This is a tulip and clone driver for Etherboot.  See the revision
+history in the tulip.c file for information on changes.  This version
+of the driver incorporates changes from Bob Edwards and Paul Mackerras
+who cantributed changes to support the TRENDnet TE100-PCIA NIC which
+uses a genuine Intel 21143-PD chipset.  There are also various code
+cleanups to make time-based activities more reliable.
+
+Of course you have to have all the usual Etherboot environment
+(bootp/dhcp/NFS) set up, and you need a Linux kernel with v0.91g
+(7.16.99) or later of the tulip.c driver compiled in to support some
+MX98715 based cards.  That file is available at:
+
+  http://cesdis.gsfc.nasa.gov/linux/drivers/test/tulip.c
+
+NOTES
+
+I've tested this driver with a SOHOware Fast 10/100 Model SDA110A,
+a Linksys LNE100TX v2.0, and a Netgear FA310TX card, and it worked at
+both 10 and 100 mbits. Other cards based on the tulip family may work as
+well.
+
+These cards are about 20$US, are supported by Linux and now Etherboot,
+and being PCI, they auto-configure IRQ and IOADDR and auto-negotiate
+10/100 half/full duplex. It seems like a pretty good value compared to
+some of the pricier cards, and can lower the cost of building/adapting
+thin client workstations substantially while giving a considerable
+performance increase.
+
+On some PCI tulip clone chipsets (MX987x5, LC82C115, LC82C168) this driver 
+lets the card choose the fastest speed it can negotiate with the peer
+device.  On other cards, it chooses 10mbit half-duplex.
+
+I burned an AM27C256 (32KByte) EPROM with mx987x5.lzrom and it worked.
+According to the data sheet the MX98715A supports up to 64K (27C512)
+EPROMs, 
+
+I've liberally commented the code and header files in the hope that it
+will help the next person who hacks the code or needs to support some
+tulip clone card, or wishes to add functionality.
+
+Anyway, please test this if you can on your tulip based card, and let
+me (mdc@etherboot.org) and the Etherboot-Discuss list
+(etherboot-discuss@lists.sourceforge.net) know how things go.  I also
+would appreciate code review by people who program.  I'm a strong
+believer in "another set of eyes".
+

+				Theory of Operation
+
+I. Board Compatibility
+
+This driver is designed for the VIA 86c100A Rhine-II PCI Fast Ethernet
+controller.
+
+II. Board-specific settings
+
+Boards with this chip are functional only in a bus-master PCI slot.
+
+Many operational settings are loaded from the EEPROM to the Config word at
+offset 0x78.  This driver assumes that they are correct.
+If this driver is compiled to use PCI memory space operations the EEPROM
+must be configured to enable memory ops.
+
+III. Driver operation
+
+IIIa. Ring buffers
+
+This driver uses two statically allocated fixed-size descriptor lists
+formed into rings by a branch from the final descriptor to the beginning of
+the list.  The ring sizes are set at compile time by RX/TX_RING_SIZE.
+
+IIIb/c. Transmit/Receive Structure
+
+This driver attempts to use a zero-copy receive and transmit scheme.
+
+Alas, all data buffers are required to start on a 32 bit boundary, so
+the driver must often copy transmit packets into bounce buffers.
+
+The driver allocates full frame size skbuffs for the Rx ring buffers at
+open() time and passes the skb->data field to the chip as receive data
+buffers.  When an incoming frame is less than RX_COPYBREAK bytes long,
+a fresh skbuff is allocated and the frame is copied to the new skbuff.
+When the incoming frame is larger, the skbuff is passed directly up the
+protocol stack.  Buffers consumed this way are replaced by newly allocated
+skbuffs in the last phase of netdev_rx().
+
+The RX_COPYBREAK value is chosen to trade-off the memory wasted by
+using a full-sized skbuff for small frames vs. the copying costs of larger
+frames.  New boards are typically used in generously configured machines
+and the underfilled buffers have negligible impact compared to the benefit of
+a single allocation size, so the default value of zero results in never
+copying packets.  When copying is done, the cost is usually mitigated by using
+a combined copy/checksum routine.  Copying also preloads the cache, which is
+most useful with small frames.
+
+Since the VIA chips are only able to transfer data to buffers on 32 bit
+boundaries, the the IP header at offset 14 in an ethernet frame isn't
+longword aligned for further processing.  Copying these unaligned buffers
+has the beneficial effect of 16-byte aligning the IP header.
+
+IIId. Synchronization
+
+The driver runs as two independent, single-threaded flows of control.  One
+is the send-packet routine, which enforces single-threaded use by the
+dev->tbusy flag.  The other thread is the interrupt handler, which is single
+threaded by the hardware and interrupt handling software.
+
+The send packet thread has partial control over the Tx ring and 'dev->tbusy'
+flag.  It sets the tbusy flag whenever it's queuing a Tx packet. If the next
+queue slot is empty, it clears the tbusy flag when finished otherwise it sets
+the 'lp->tx_full' flag.
+
+The interrupt handler has exclusive control over the Rx ring and records stats
+from the Tx ring.  After reaping the stats, it marks the Tx queue entry as
+empty by incrementing the dirty_tx mark. Iff the 'lp->tx_full' flag is set, it
+clears both the tx_full and tbusy flags.
+
+IV. Notes
+
+IVb. References

+Preliminary VT86C100A manual from http://www.via.com.tw/

+
+IVc. Errata
+
+The VT86C100A manual is not reliable information.
+The chip does not handle unaligned transmit or receive buffers, resulting
+in significant performance degradation for bounce buffer copies on transmit
+and unaligned IP headers on receive.
+The chip does not pad to minimum transmit length.

+/** @file
+ *
+ * Error codes
+ *
+ * Return status codes as used within gPXE are designed to allow for
+ * maximum visibility into the source of an error even in an end-user
+ * build with no debugging.  They are constructed as follows:
+ *
+ * Bits 7-0 : PXE error code
+ *
+ * This is the closest equivalent PXE error code
+ * (e.g. PXENV_STATUS_OUT_OF_RESOURCES), and is the only part of the
+ * error that will be returned via the PXE API, since PXE has
+ * predefined error codes.
+ *
+ * Bits 12-8 : Per-file disambiguator
+ *
+ * When the same error number can be generated from multiple points
+ * within a file, this field can be used to identify the unique
+ * instance.
+ *
+ * Bits 23-13 : File identifier
+ *
+ * This is a unique identifier for the file generating the error
+ * (e.g. ERRFILE_tcp for tcp.c).
+ *
+ * Bits 30-24 : POSIX error code
+ *
+ * This is the closest equivalent POSIX error code (e.g. ENOMEM).
+ *
+ * Bit 31 : Reserved
+ *
+ * Errors are usually return as negative error numbers (e.g. -EINVAL);
+ * bit 31 is therefore unusable.
+ *
+ *
+ * The convention within the code is that errors are negative and
+ * expressed using the POSIX error code and (optionally) a per-file
+ * disambiguator, e.g.
+ *
+ *     return -EINVAL;
+ *
+ * or
+ *
+ *     #define ETCP_BAD_CHECKSUM EUNIQ_02
+ *     return -( EINVAL | ETCP_BAD_CHECKSUM )
+ *
+ * By various bits of preprocessor magic, the PXE error code and file
+ * identifier are already incorporated into the definition of the
+ * POSIX error code, which keeps the code relatively clean.
+ *
+ *
+ * Functions that wish to return failures should be declared as
+ * returning an integer @c rc "Return status code".  A return value of
+ * zero indicates success, a non-zero value indicates failure.  The
+ * return value can be passed directly to strerror() in order to
+ * generate a human-readable error message, e.g.
+ *
+ *     if ( ( rc = some_function ( ... ) ) != 0 ) {
+ *         DBG ( "Whatever I was trying to do failed: %s\n", strerror ( rc ) );
+ *         return rc;
+ *     }
+ *
+ * As illustrated in the above example, error returns should generally
+ * be directly propagated upward to the calling function.
+ *

+ * An ATA Logical Block Address
+ *
+ * ATA controllers have three byte-wide registers for specifying the
+ * block address: LBA Low, LBA Mid and LBA High.  This allows for a
+ * 24-bit address.  Some devices support the "48-bit address feature
+ * set" (LBA48), in which case each of these byte-wide registers is
+ * actually a two-entry FIFO, and the "previous" byte pushed into the
+ * FIFO is used as the corresponding high-order byte.  So, to set up
+ * the 48-bit address 0x123456abcdef, you would issue
+ *
+ *     0x56 -> LBA Low register
+ *     0xef -> LBA Low register
+ *     0x34 -> LBA Mid register
+ *     0xcd -> LBA Mid register
+ *     0x12 -> LBA High register
+ *     0xab -> LBA High register
+ *
+ * This structure encapsulates this information by providing a single
+ * 64-bit integer in native byte order, unioned with bytes named so
+ * that the sequence becomes
+ *
+ *     low_prev  -> LBA Low register
+ *     low_cur   -> LBA Low register
+ *     mid_prev  -> LBA Mid register
+ *     mid_cur   -> LBA Mid register
+ *     high_prev -> LBA High register
+ *     high_cur  -> LBA High register
+ *
+ * Just to complicate matters further, in non-LBA48 mode it is
+ * possible to have a 28-bit address, in which case bits 27:24 must be
+ * written into the low four bits of the Device register.

+ *
+ * At the time of writing, there are a few other modifications to

+/** @page ifdef_harmful #ifdef considered harmful
+ *
+ * Overuse of @c #ifdef has long been a problem in Etherboot.
+ * Etherboot provides a rich array of features, but all these features
+ * take up valuable space in a ROM image.  The traditional solution to
+ * this problem has been for each feature to have its own @c #ifdef
+ * option, allowing the feature to be compiled in only if desired.
+ *
+ * The problem with this is that it becomes impossible to compile, let
+ * alone test, all possible versions of Etherboot.  Code that is not
+ * typically used tends to suffer from bit-rot over time.  It becomes
+ * extremely difficult to predict which combinations of compile-time
+ * options will result in code that can even compile and link
+ * correctly.
+ *
+ * To solve this problem, we have adopted a new approach from
+ * Etherboot 5.5 onwards.  @c #ifdef is now "considered harmful", and
+ * its use should be minimised.  Separate features should be
+ * implemented in separate @c .c files, and should \b always be
+ * compiled (i.e. they should \b not be guarded with a @c #ifdef @c
+ * MY_PET_FEATURE statement).  By making (almost) all code always
+ * compile, we avoid the problem of bit-rot in rarely-used code.
+ *
+ * The file config.h, in combination with the @c make command line,
+ * specifies the objects that will be included in any particular build
+ * of Etherboot.  For example, suppose that config.h includes the line
+ *
+ * @code
+ *
+ *   #define CONSOLE_SERIAL
+ *   #define DOWNLOAD_PROTO_TFTP
+ *
+ * @endcode
+ *
+ * When a particular Etherboot image (e.g. @c bin/rtl8139.zdsk) is
+ * built, the options specified in config.h are used to drag in the
+ * relevant objects at link-time.  For the above example, serial.o and
+ * tftp.o would be linked in.
+ *
+ * There remains one problem to solve: how do these objects get used?
+ * Traditionally, we had code such as
+ *
+ * @code
+ *
+ *    #ifdef CONSOLE_SERIAL
+ *      serial_init();
+ *    #endif
+ *
+ * @endcode
+ *
+ * in main.c, but this reintroduces @c #ifdef and so is a Bad Idea.
+ * We cannot simply remove the @c #ifdef and make it
+ *
+ * @code
+ *
+ *   serial_init();
+ *
+ * @endcode
+ *
+ * because then serial.o would end up always being linked in.
+ *
+ * The solution is to use @link tables.h linker tables @endlink.
+ *
+ */
+
+/** @file
+ *
+ * Linker tables
+ *
+ * Read @ref ifdef_harmful first for some background on the motivation
+ * for using linker tables.
+ *
+ * This file provides macros for dealing with linker-generated tables
+ * of fixed-size symbols.  We make fairly extensive use of these in
+ * order to avoid @c #ifdef spaghetti and/or linker symbol pollution.
+ * For example, instead of having code such as
+ *
+ * @code
+ *
+ *    #ifdef CONSOLE_SERIAL
+ *      serial_init();
+ *    #endif
+ *
+ * @endcode
+ *
+ * we make serial.c generate an entry in the initialisation function
+ * table, and then have a function call_init_fns() that simply calls
+ * all functions present in this table.  If and only if serial.o gets
+ * linked in, then its initialisation function will be called.  We
+ * avoid linker symbol pollution (i.e. always dragging in serial.o
+ * just because of a call to serial_init()) and we also avoid @c
+ * #ifdef spaghetti (having to conditionalise every reference to
+ * functions in serial.c).
+ *
+ * The linker script takes care of assembling the tables for us.  All
+ * our table sections have names of the format @c .tbl.NAME.NN where
+ * @c NAME designates the data structure stored in the table (e.g. @c
+ * init_fns) and @c NN is a two-digit decimal number used to impose an
+ * ordering upon the tables if required.  @c NN=00 is reserved for the
+ * symbol indicating "table start", and @c NN=99 is reserved for the
+ * symbol indicating "table end".
+ *
+ * As an example, suppose that we want to create a "frobnicator"
+ * feature framework, and allow for several independent modules to
+ * provide frobnicating services.  Then we would create a frob.h
+ * header file containing e.g.
+ *
+ * @code
+ *
+ *   struct frobnicator {
+ *      const char *name;		// Name of the frobnicator
+ *	void ( *frob ) ( void ); 	// The frobnicating function itself
+ *   };
+ *
+ *   #define FROBNICATORS __table ( struct frobnicator, "frobnicators" )
+ *
+ *   #define __frobnicator __table_entry ( FROBNICATORS, 01 )
+ *
+ * @endcode
+ *
+ * Any module providing frobnicating services would look something
+ * like
+ *
+ * @code
+ *
+ *   #include "frob.h"
+ *
+ *   static void my_frob ( void ) {
+ *	// Do my frobnicating
+ *	...

+
+/** @page rc80211 Rate control philosophy
+ *
+ * We want to maximize our transmission speed, to the extent that we
+ * can do that without dropping undue numbers of packets. We also
+ * don't want to take up very much code space, so our algorithm has to
+ * be pretty simple
+ *
+ * When we receive a packet, we know what rate it was transmitted at,
+ * and whether it had to be retransmitted to get to us.
+ *
+ * When we send a packet, we hear back how many times it had to be
+ * retried to get through, and whether it got through at all.
+ *
+ * Indications of TX success are more reliable than RX success, but RX
+ * information helps us know where to start.
+ *
+ * To handle all of this, we keep for each rate and each direction (TX
+ * and RX separately) some state information for the most recent
+ * packets on that rate and the number of packets for which we have
+ * information. The state is a 32-bit unsigned integer in which two
+ * bits represent a packet: 11 if it went through well, 10 if it went
+ * through with one retry, 01 if it went through with more than one
+ * retry, or 00 if it didn't go through at all. We define the
+ * "goodness" for a particular (rate, direction) combination as the
+ * sum of all the 2-bit fields, times 33, divided by the number of
+ * 2-bit fields containing valid information (16 except when we're
+ * starting out). The number produced is between 0 and 99; we use -1
+ * for rates with less than 4 RX packets or 1 TX, as an indicator that
+ * we do not have enough information to rely on them.
+ *
+ * In deciding which rates are best, we find the weighted average of
+ * TX and RX goodness, where the weighting is by number of packets
+ * with data and TX packets are worth 4 times as much as RX packets.
+ * The weighted average is called "net goodness" and is also a number
+ * between 0 and 99.  If 3 consecutive packets fail transmission
+ * outright, we automatically ratchet down the rate; otherwise, we
+ * switch to the best rate whenever the current rate's goodness falls
+ * below some threshold, and try increasing our rate when the goodness
+ * is very high.
+ *
+ * This system is optimized for gPXE's style of usage. Because normal
+ * operation always involves receiving something, we'll make our way
+ * to the best rate pretty quickly. We tend to follow the lead of the
+ * sending AP in choosing rates, but we won't use rates for long that
+ * don't work well for us in transmission. We assume gPXE won't be
+ * running for long enough that rate patterns will change much, so we
+ * don't have to keep time counters or the like.  And if this doesn't
+ * work well in practice there are many ways it could be tweaked.
+ *
+ * To avoid staying at 1Mbps for a long time, we don't track any
+ * transmitted packets until we've set our rate based on received
+ * packets.

+ *
+ * Scalable Local Area Multicast protocol
+ *
+ * The SLAM protocol is supported only by Etherboot; it was designed
+ * and implemented by Eric Biederman.  A server implementation is
+ * available in contrib/mini-slamd.  There does not appear to be any
+ * documentation beyond a few sparse comments in Etherboot's
+ * proto_slam.c.
+ *
+ * SLAM packets use three types of data field:
+ *
+ *  Nul : A single NUL (0) byte, used as a list terminator
+ *
+ *  Raw : A block of raw data
+ *
+ *  Int : A variable-length integer, in big-endian order.  The length
+ *        of the integer is encoded in the most significant three bits.
+ *
+ * Packets received by the client have the following layout:
+ *
+ *  Int : Transaction identifier.  This is an opaque value.
+ *
+ *  Int : Total number of bytes in the transfer.
+ *
+ *  Int : Block size, in bytes.
+ *
+ *  Int : Packet sequence number within the transfer (if this packet
+ *        contains data).
+ *
+ *  Raw : Packet data (if this packet contains data).
+ *
+ * Packets transmitted by the client consist of a run-length-encoded
+ * representation of the received-blocks bitmap, looking something
+ * like:
+ *
+ *  Int : Number of consecutive successfully-received packets
+ *  Int : Number of consecutive missing packets
+ *  Int : Number of consecutive successfully-received packets
+ *  Int : Number of consecutive missing packets
+ *  ....
+ *  Nul

+ ============================================================================
+ LZO -- a real-time data compression library
+ ============================================================================
+
+ Author  : Markus Franz Xaver Johannes Oberhumer
+           <markus@oberhumer.com>
+           http://www.oberhumer.com/opensource/lzo/
+ Version : 2.03
+ Date    : 30 Apr 2008
+
+
+ Abstract
+ --------
+ LZO is a portable lossless data compression library written in ANSI C.
+ It offers pretty fast compression and very fast decompression.
+ Decompression requires no memory.
+
+ In addition there are slower compression levels achieving a quite
+ competitive compression ratio while still decompressing at
+ this very high speed.
+
+ The LZO algorithms and implementations are copyrighted OpenSource
+ distributed under the GNU General Public License.
+
+
+ Introduction
+ ------------
+ LZO is a data compression library which is suitable for data
+ de-/compression in real-time. This means it favours speed
+ over compression ratio.
+
+ The acronym LZO is standing for Lempel-Ziv-Oberhumer.
+
+ LZO is written in ANSI C. Both the source code and the compressed
+ data format are designed to be portable across platforms.
+
+ LZO implements a number of algorithms with the following features:
+
+ - Decompression is simple and *very* fast.
+ - Requires no memory for decompression.
+ - Compression is pretty fast.
+ - Requires 64 kB of memory for compression.
+ - Allows you to dial up extra compression at a speed cost in the
+   compressor. The speed of the decompressor is not reduced.
+ - Includes compression levels for generating pre-compressed
+   data which achieve a quite competitive compression ratio.
+ - There is also a compression level which needs only 8 kB for compression.
+ - Algorithm is thread safe.
+ - Algorithm is lossless.
+
+ LZO supports overlapping compression and in-place decompression.
+
+
+ Design criteria
+ ---------------
+ LZO was designed with speed in mind. Decompressor speed has been
+ favoured over compressor speed. Real-time decompression should be
+ possible for virtually any application. The implementation of the
+ LZO1X decompressor in optimized i386 assembler code runs about at
+ the third of the speed of a memcpy() - and even faster for many files.
+
+ In fact I first wrote the decompressor of each algorithm thereby
+ defining the compressed data format, verified it with manually
+ created test data and at last added the compressor.
+
+
+ Performance
+ -----------
+ To keep you interested, here is an overview of the average results
+ when compressing the Calgary Corpus test suite with a blocksize
+ of 256 kB, originally done on an ancient Intel Pentium 133.
+
+ The naming convention of the various algorithms goes LZOxx-N, where N is
+ the compression level. Range 1-9 indicates the fast standard levels using
+ 64 kB memory for compression. Level 99 offers better compression at the
+ cost of more memory (256 kB), and is still reasonably fast.
+ Level 999 achieves nearly optimal compression - but it is slow
+ and uses much memory, and is mainly intended for generating
+ pre-compressed data.
+
+ The C version of LZO1X-1 is about 4-5 times faster than the fastest
+ zlib compression level, and it also outperforms other algorithms
+ like LZRW1-A and LZV in both compression ratio and compression speed
+ and decompression speed.

+ Notes:
+  - CxB is the number of blocks
+  - K/s is the speed measured in 1000 uncompressed bytes per second
+  - the assembler decompressors are even faster
+
+
+ Short documentation
+ -------------------
+ LZO is a block compression algorithm - it compresses and decompresses
+ a block of data. Block size must be the same for compression
+ and decompression.
+
+ LZO compresses a block of data into matches (a sliding dictionary)
+ and runs of non-matching literals. LZO takes care about long matches
+ and long literal runs so that it produces good results on highly
+ redundant data and deals acceptably with non-compressible data.
+
+ When dealing with uncompressible data, LZO expands the input
+ block by a maximum of 16 bytes per 1024 bytes input.
+
+ I have verified LZO using such tools as valgrind and other memory checkers.
+ And in addition to compressing gigabytes of files when tuning some parameters
+ I have also consulted various `lint' programs to spot potential portability
+ problems. LZO is free of any known bugs.
+
+
+ The algorithms
+ --------------
+ There are too many algorithms implemented. But I want to support
+ unlimited backward compatibility, so I will not reduce the LZO
+ distribution in the future.
+
+ As the many object files are mostly independent of each other, the
+ size overhead for an executable statically linked with the LZO library
+ is usually pretty low (just a few kB) because the linker will only add
+ the modules that you are actually using.
+
+ I first published LZO1 and LZO1A in the Internet newsgroups
+ comp.compression and comp.compression.research in March 1996.
+ They are mainly included for compatibility reasons. The LZO2A
+ decompressor is too slow, and there is no fast compressor anyway.
+
+ My experiments have shown that LZO1B is good with a large blocksize
+ or with very redundant data, LZO1F is good with a small blocksize or
+ with binary data and that LZO1X is often the best choice of all.
+ LZO1Y and LZO1Z are almost identical to LZO1X - they can achieve a
+ better compression ratio on some files.
+ Beware, your mileage may vary.
+
+
+ Usage of the library
+ --------------------
+ Despite of its size, the basic usage of LZO is really very simple.
+
+ Let's assume you want to compress some data with LZO1X-1:
+   A) compression
+      * include <lzo/lzo1x.h>
+        call lzo_init()
+        compress your data with lzo1x_1_compress()
+      * link your application with the LZO library
+   B) decompression
+      * include <lzo/lzo1x.h>
+        call lzo_init()
+        decompress your data with lzo1x_decompress()
+      * link your application with the LZO library
+
+ The program examples/simple.c shows a fully working example.
+ See also LZO.FAQ for more information.
+
+
+ Building LZO
+ ------------
+ As LZO uses Autoconf+Automake+Libtool the building process under
+ UNIX systems should be very unproblematic. Shared libraries are
+ supported on many architectures as well.
+ For detailed instructions see the file INSTALL.
+
+ Please note that due to the design of the ELF executable format
+ the performance of a shared library on i386 systems (e.g. Linux)
+ is a little bit slower, so you may want to link your applications
+ with the static version (liblzo2.a) anyway.
+
+ For building under DOS, Win16, Win32, OS/2 and other systems
+ take a look at the file B/00readme.txt.
+
+ In case of troubles (like decompression data errors) try recompiling
+ everything without optimizations - LZO may break the optimizer
+ of your compiler. See the file BUGS.
+
+ LZO is written in ANSI C. In particular this means:
+   - your compiler must understand prototypes
+   - your compiler must understand prototypes in function pointers
+   - your compiler must correctly promote integrals ("value-preserving")
+   - your preprocessor must implement #elif, #error and stringizing
+   - you must have a conforming and correct <limits.h> header
+   - you must have <stddef.h>, <string.h> and other ANSI C headers
+   - you should have size_t and ptrdiff_t
+
+
+ Portability
+ -----------
+ I have built and tested LZO successfully on a variety of platforms
+ including DOS (16 + 32 bit), Windows 3.x (16-bit), Win32, Win64,
+ Linux, *BSD, HP-UX and many more.
+
+ LZO is also reported to work under AIX, ConvexOS, IRIX, MacOS, PalmOS (Pilot),
+ PSX (Sony Playstation), Solaris, SunOS, TOS (Atari ST) and VxWorks.
+ Furthermore it is said that its performance on a Cray is superior
+ to all other machines...
+
+ And I think it would be much fun to translate the decompressors
+ to Z-80 or 6502 assembly.
+
+
+ The future
+ ----------
+ Here is what I'm planning for the next months. No promises, though...
+
+ - interfaces to .NET and Mono
+ - interfaces to Perl, Java, Python, Delphi, Visual Basic, ...
+ - improve documentation and API reference
+
+
+ Some comments about the source code
+ -----------------------------------
+ Be warned: the main source code in the `src' directory is a
+ real pain to understand as I've experimented with hundreds of slightly
+ different versions. It contains many #if and some gotos, and
+ is *completely optimized for speed* and not for readability.
+ Code sharing of the different algorithms is implemented by stressing
+ the preprocessor - this can be really confusing. Lots of marcos and
+ assertions don't make things better.
+
+ Nevertheless LZO compiles very quietly on a variety of
+ compilers with the highest warning levels turned on, even
+ in C++ mode.

+filesystem.  It works the same way as \fBSYSLINUX\fP, with a few slight modifications.
+It is intended to simplify first-time installation of Linux, and for creation of
+rescue and other special-purpose boot disks.
+.PP
+The installer is designed to be run on a mounted directory.  For example, if you have an
+ext2 or ext3 usb key mounted on /mnt, you can run the following command:
+.IP
+.B extlinux --install /mnt
+.SH OPTIONS
+.TP
+\fB\-H\fR, \fB\-\-heads\fR=#
+Force the number of heads.
+.TP
+\fB\-i\fR, \fB\-\-install\fR
+Install over the current bootsector.
+.TP
+\fB\-O\fR, \fB\-\-clear\-once\fR
+Clear the boot-once command.
+.TP
+\fB\-o\fR, \fB\-\-once\fR=\fIcommand\fR
+Execute a command once upon boot.
+.TP
+\fB\-M\fR, \fB\-\-menu\-save\fR=\fIlabel\fR
+Set the label to select as default on the next boot
+.TP
+\fB\-r\fR, \fB\-\-raid\fR

+Updates a previous \fBEXTLINUX\fP installation.
+.TP
+\fB\-z\fR, \fB\-\-zip\fR
+Force zipdrive geometry (-H 64 -S 32).
+.SH FILES
+The extlinux configuration file needs to be named extlinux.conf and needs to be stored in the extlinux installation directory. For more information about the contents of extlinux.conf, see syslinux(1) manpage, section files.
+.SH BUGS
+I would appreciate hearing of any problems you have with \s-1SYSLINUX\s+1.  I
+would also like to hear from you if you have successfully used \s-1SYSLINUX\s+1,
+especially if you are using it for a distribution.
+.PP
+If you are reporting problems, please include all possible information
+about your system and your BIOS; the vast majority of all problems
+reported turn out to be BIOS or hardware bugs, and I need as much
+information as possible in order to diagnose the problems.
+.PP
+There is a mailing list for discussion among \s-1SYSLINUX\s+1 users and for
+announcements of new and test versions. To join, send a message to
+majordomo@linux.kernel.org with the line:

+.TH SYSLINUX 1 "19 July 2010" "SYSLINUX"
+.SH NAME
+syslinux \- install the \s-1SYSLINUX\s+1 bootloader on a FAT filesystem
+.SH SYNOPSIS
+.B syslinux
+[\fBOPTIONS\fP]
+.I device
+.SH DESCRIPTION
+\fBSyslinux\fP is a boot loader for the Linux operating system which
+operates off an MS-DOS/Windows FAT filesystem. It is intended to
+simplify first-time installation of Linux, and for creation of rescue
+and other special-purpose boot disks.
+.PP
+In order to create a bootable Linux floppy using \fBSyslinux\fP, prepare a
+normal MS-DOS formatted floppy. Copy one or more Linux kernel files to
+it, then execute the command:
+.IP
+.B syslinux \-\-install /dev/fd0
+.PP
+This will alter the boot sector on the disk and copy a file named
+.I ldlinux.sys
+into its root directory.
+.PP
+On boot time, by default, the kernel will be loaded from the image named
+LINUX on the boot floppy.  This default can be changed, see the section
+on the \fBsyslinux\fP configuration file.
+.PP
+If the Shift or Alt keys are held down during boot, or the Caps or Scroll
+locks are set, \fBsyslinux\fP will display a
+.BR lilo (8)
+-style "boot:" prompt. The user can then type a kernel file name
+followed by any kernel parameters. The \s-1SYSLINUX\s+1 bootloader
+does not need to know about the kernel file in advance; all that is
+required is that it is a file located in the root directory on the
+disk.
+.PP
+\fBSyslinux\fP supports the loading of initial ramdisks (initrd) and the
+bzImage kernel format.
+.SH OPTIONS
+.TP
+\fB\-i\fP, \fB\-\-install\fP
+Install \s-1SYSLINUX\s+1 on a new medium, overwriting any previously
+installed bootloader.
+.TP
+\fB\-U\fP, \fB\-\-update\fP
+Install \s-1SYSLINUX\s+1 on a new medium if and only if a version of
+\s-1SYSLINUX\s+1 is already installed.
+.TP
+\fB\-s\fP, \fB\-\-stupid\fP
+Install a "safe, slow and stupid" version of \s-1SYSLINUX\s+1. This version may
+work on some very buggy BIOSes on which \s-1SYSLINUX\s+1 would otherwise fail.
+If you find a machine on which the \-s option is required to make it boot
+reliably, please send as much info about your machine as you can, and include
+the failure mode.
+.TP
+\fB\-f\fP, \fB\-\-force\fP
+Force install even if it appears unsafe.
+.TP
+\fB\-r\fP, \fB\-\-raid\fB
+RAID mode.  If boot fails, tell the BIOS to boot the next device in
+the boot sequence (usually the next hard disk) instead of stopping
+with an error message.  This is useful for RAID-1 booting.
+.TP
+\fB\-d\fP, \fB\-\-directory\fP \fIsubdirectory\fP

+.SH FILES
+.SS "Configuration file"
+All the configurable defaults in \s-1SYSLINUX\s+1 can be changed by putting a
+file called
+.B syslinux.cfg
+in the install directory of the boot disk. This
+is a text file in either UNIX or DOS format, containing one or more of
+the following items (case is insensitive for keywords).
+.PP
+This list is out of date.
+.PP
+In the configuration file blank lines and comment lines beginning
+with a hash mark (#) are ignored.
+.TP
+\fBdefault\fP \fIkernel\fP [ \fIoptions ...\fP ]
+Sets the default command line. If \fBsyslinux\fP boots automatically,
+it will act just as if the entries after "default" had been typed in
+at the "boot:" prompt.
+.IP
+If no DEFAULT or UI statement is found, or the configuration file is missing
+entirely, \s-1SYSLINUX\s+1 drops to the boot: prompt with an error message (if
+NOESCAPE is set, it stops with a "boot failed" message; this is also the case
+for PXELINUX if the configuration file is not found.)
+.TP
+NOTE: Until \s-1SYSLINUX\s+1 3.85, if no configuration file is present, or no
+"default" entry is present in the configuration file, the default is
+"linux auto".
+.TP
+Even earlier versions of \s-1SYSLINUX\s+1 used to automatically
+append the string "auto" to whatever the user specified using
+the DEFAULT command.  As of version 1.54, this is no longer
+true, as it caused problems when using a shell as a substitute
+for "init."  You may want to include this option manually.
+.TP
+.BI append " options ..."
+Add one or more \fIoptions\fP to the kernel command line. These are added both
+for automatic and manual boots. The options are added at the very beginning of
+the kernel command line, usually permitting explicitly entered kernel options
+to override them. This is the equivalent of the
+.BR lilo (8)
+ "append" option.
+.PP
+.nf
+.BI label\  label
+.RS 2
+.BI kernel\  image
+.BI append\  options\ ...
+.RE
+.fi
+.RS
+Indicates that if \fIlabel\fP is entered as the kernel to boot, \fBsyslinux\fP should
+instead boot \fIimage\fP, and the specified "append" options should be used
+instead of the ones specified in the global section of the file (before the
+first "label" command.) The default for \fIimage\fP is the same as \fIlabel\fP,
+and if no "append" is given the default is to use the global entry (if any).
+Use "append -" to use no options at all.  Up to 128 "label" entries are
+permitted.
+.TP
+.B Notes:
+Labels are mangled as if they were DOS filenames, and must be unique after
+mangling.  For example, two labels "v2.1.30" and "v2.1.31" will not be
+distinguishable.
+.IP
+The "image" doesn't have to be a Linux kernel; it can be a boot sector or a
+COMBOOT file (see below.)
+.RE
+.TP
+.BI implicit\  flag_val
+If \fIflag_val\fP is 0, do not load a kernel image unless it has been
+explicitly named in a "label" statement.  The default is 1.
+.TP
+.BI timeout\  timeout
+Indicates how long to wait at the "boot:" prompt until booting automatically, in
+units of 1/10 s. The timeout is cancelled as soon as the user types anything
+on the keyboard, the assumption being that the user will complete the command
+line already begun. A timeout of zero will disable the timeout completely,
+this is also the default. The maximum possible timeout value is 35996;
+corresponding to just below one hour.
+.TP
+\fBserial\fP \fIport\fP [ \fIbaudrate\fP ]
+Enables a serial port to act as the console. "port" is a number (0 = /dev/ttyS0
+= COM1, etc.); if "baudrate" is omitted, the baud rate defaults to 9600 bps.
+The serial parameters are hardcoded to be 8 bits, no parity, 1 stop bit.
+.IP
+For this directive to be guaranteed to work properly, it
+should be the first directive in the configuration file.
+.TP
+.BI font\  filename
+Load a font in .psf format before displaying any output (except the copyright
+line, which is output as ldlinux.sys itself is loaded.) \fBsyslinux\fP only loads
+the font onto the video card; if the .psf file contains a Unicode table it is
+ignored.  This only works on EGA and VGA cards; hopefully it should do nothing
+on others.
+.TP
+.BI kbdmap\  keymap
+Install a simple keyboard map. The keyboard remapper used is \fIvery\fP
+simplistic (it simply remaps the keycodes received from the BIOS, which means
+that only the key combinations relevant in the default layout \- usually U.S.
+English \- can be mapped) but should at least help people with AZERTY keyboard
+layout and the locations of = and , (two special characters used heavily on the
+Linux kernel command line.)
+.IP
+The included program
+.BR keytab-lilo.pl (8)
+from the
+.BR lilo (8)
+ distribution can be used to create such keymaps.
+.TP
+.BI display\  filename
+Displays the indicated file on the screen at boot time (before the boot:
+prompt, if displayed). Please see the section below on DISPLAY files. If the
+file is missing, this option is simply ignored.
+.TP
+.BI prompt\  flag_val
+If \fIflag_val\fP is 0, display the "boot:" prompt only if the Shift or Alt key
+is pressed, or Caps Lock or Scroll lock is set (this is the default).  If
+\fIflag_val\fP is 1, always display the "boot:" prompt.
+.PP
+.nf
+.BI f1\  filename
+.BI f2\  filename
+.I ...
+.BI f9\  filename
+.BI f10\  filename
+.BI f11\  filename
+.BI f12\  filename
+.fi
+.RS
+Displays the indicated file on the screen when a function key is pressed at the
+"boot:" prompt. This can be used to implement pre-boot online help (presumably
+for the kernel command line options.)
+.RE
+.IP
+When using the serial console, press \fI<Ctrl-F><digit>\fP to get to
+the help screens, e.g. \fI<Ctrl-F>2\fP to get to the f2 screen.  For
+f10-f12, hit \fI<Ctrl-F>A\fP, \fI<Ctrl-F>B\fP, \fI<Ctrl-F>C\fP.  For
+compatiblity with earlier versions, f10 can also be entered as
+\fI<Ctrl-F>0\fP.
+.SS "Display file format"
+DISPLAY and function-key help files are text files in either DOS or UNIX
+format (with or without \fI<CR>\fP). In addition, the following special codes
+are interpreted:
+.TP
+\fI<FF>\fP = \fI<Ctrl-L>\fP = ASCII 12
+Clear the screen, home the cursor.  Note that the screen is
+filled with the current display color.
+.TP
+\fI<SI><bg><fg>\fP, \fI<SI>\fP = \fI<Ctrl-O>\fP = ASCII 15
+Set the display colors to the specified background and foreground colors, where
+\fI<bg>\fP and \fI<fg>\fP are hex digits, corresponding to the standard PC
+display attributes:
+.IP
+.nf
+.ta \w'5 = dark purple    'u
+0 = black	8 = dark grey
+1 = dark blue	9 = bright blue
+2 = dark green	a = bright green
+3 = dark cyan	b = bright cyan
+4 = dark red	c = bright red
+5 = dark purple	d = bright purple
+6 = brown	e = yellow
+7 = light grey	f = white
+.fi
+.IP
+Picking a bright color (8-f) for the background results in the
+corresponding dark color (0-7), with the foreground flashing.
+.IP
+colors are not visible over the serial console.
+.TP
+\fI<CAN>\fPfilename\fI<newline>\fP, \fI<CAN>\fP = \fI<Ctrl-X>\fP = ASCII 24
+If a VGA display is present, enter graphics mode and display
+the graphic included in the specified file.  The file format
+is an ad hoc format called LSS16; the included Perl program
+"ppmtolss16" can be used to produce these images.  This Perl
+program also includes the file format specification.
+.IP
+The image is displayed in 640x480 16-color mode.  Once in
+graphics mode, the display attributes (set by \fI<SI>\fP code
+sequences) work slightly differently: the background color is
+ignored, and the foreground colors are the 16 colors specified
+in the image file.  For that reason, ppmtolss16 allows you to
+specify that certain colors should be assigned to specific
+color indicies.
+.IP
+Color indicies 0 and 7, in particular, should be chosen with
+care: 0 is the background color, and 7 is the color used for
+the text printed by \s-1SYSLINUX\s+1 itself.
+.TP
+\fI<EM>\fP, \fI<EM>\fP = \fI<Ctrl-U>\fP = ASCII 25
+If we are currently in graphics mode, return to text mode.
+.TP
+\fI<DLE>\fP..\fI<ETB>\fB, \fI<Ctrl-P>\fP..\fI<Ctrl-W>\fP = ASCII 16-23
+These codes can be used to select which modes to print a
+certain part of the message file in.  Each of these control
+characters select a specific set of modes (text screen,
+graphics screen, serial port) for which the output is actually
+displayed:
+.IP
+.nf
+Character                       Text    Graph   Serial
+------------------------------------------------------
+<DLE> = <Ctrl-P> = ASCII 16     No      No      No
+<DC1> = <Ctrl-Q> = ASCII 17     Yes     No      No
+<DC2> = <Ctrl-R> = ASCII 18     No      Yes     No
+<DC3> = <Ctrl-S> = ASCII 19     Yes     Yes     No
+<DC4> = <Ctrl-T> = ASCII 20     No      No      Yes
+<NAK> = <Ctrl-U> = ASCII 21     Yes     No      Yes
+<SYN> = <Ctrl-V> = ASCII 22     No      Yes     Yes
+<ETB> = <Ctrl-W> = ASCII 23     Yes     Yes     Yes
+.fi
+.IP
+For example:
+.nf
+<DC1>Text mode<DC2>Graphics mode<DC4>Serial port<ETB>
+.fi
+ ... will actually print out which mode the console is in!
+.TP
+\fI<SUB>\fP = \fI<Ctrl-Z>\fP = ASCII 26
+End of file (DOS convention).
+.SS Comboot Images and other operating systems
+This version of \fBsyslinux\fP supports chain loading of other operating
+systems (such as MS-DOS and its derivatives, including Windows 95/98),
+as well as COMBOOT-style standalone executables (a subset of DOS .COM
+files; see separate section below.)
+.PP
+Chain loading requires the boot sector of the foreign operating system
+to be stored in a file in the root directory of the filesystem.
+Because neither Linux kernels, boot sector images, nor COMBOOT files
+have reliable magic numbers, \fBsyslinux\fP will look at the file
+extension. The following extensions are recognised:
+.PP
+.nf
+.ta \w'none or other    'u
+none or other	Linux kernel image
+CBT	COMBOOT image (not runnable from DOS)
+BSS	Boot sector (DOS superblock will be patched in)
+BS	Boot sector
+COM	COMBOOT image (runnable from DOS)
+.fi
+.PP
+For filenames given on the command line, \fBsyslinux\fP will search for the
+file by adding extensions in the order listed above if the plain
+filename is not found. Filenames in KERNEL statements must be fully
+qualified.
+.PP
+A COMBOOT file is a standalone executable in DOS .COM format. They
+can, among other things, be produced by the Etherboot package by
+Markus Gutschke and Ken Yap. The following requirements apply for
+these files to be sufficiently "standalone" for \fBsyslinux\fP to be able to
+load and run them:
+.IP \(bu
+The program must not execute any DOS calls (since there is no
+DOS), although it may call the BIOS. The only exception is that
+the program may execute INT 20h (Terminate Program) to return to
+the \fBsyslinux\fP prompt. Note especially that INT 21h AH=4Ch, INT 21h
+AH=31h or INT 27h are not supported.
+.IP \(bu
+Only the fields pspInt20 at offset 00h, pspNextParagraph at offset 02h and
+pspCommandTail at offset 80h (contains the arguments from the \fBsyslinux\fP command
+line) in the PSP are supported. All other fields will contain zero.
+.IP \(bu
+The program must not modify any main memory outside its 64K segment if it
+returns to \fBsyslinux\fP via INT 20h.
+.PP
+\fBSyslinux\fP currently doesn't provide any form of API for the use of
+COMBOOT files.  If there is need, a future version may contain an INT
+interface to some \fBsyslinux\fP functions; please contact me if you have a
+need or ideas for such an API.
+.SS Novice protection
+\fBSyslinux\fP will attempt to detect if the user is trying to boot on a 286
+or lower class machine, or a machine with less than 608K of low ("DOS")
+RAM (which means the Linux boot sequence cannot complete).  If so, a
+message is displayed and the boot sequence aborted.  Holding down the
+Ctrl key while booting disables this feature.
+.PP
+The compile time and date of a specific \fBsyslinux\fP version can be obtained
+by the DOS command "type ldlinux.sys". This is also used as the
+signature for the LDLINUX.SYS file, which must match the boot sector
+.PP
+Any file that \fBsyslinux\fP uses can be marked hidden, system or readonly if
+so is convenient; \fBsyslinux\fP ignores all file attributes.  The \s-1SYSLINUX\s+1
+installed automatically sets the readonly attribute on LDLINUX.SYS.
+.SS Bootable CD-ROMs
+\s-1SYSLINUX\s+1 can be used to create bootdisk images for El
+Torito-compatible bootable CD-ROMs. However, it appears that many
+BIOSes are very buggy when it comes to booting CD-ROMs. Some users
+have reported that the following steps are helpful in making a CD-ROM
+that is bootable on the largest possible number of machines:
+.IP \(bu
+Use the -s (safe, slow and stupid) option to \s-1SYSLINUX\s+1
+.IP \(bu
+Put the boot image as close to the beginning of the
+ISO 9660 filesystem as possible.
+.PP
+A CD-ROM is so much faster than a floppy that the -s option shouldn't
+matter from a speed perspective.
+.PP
+Of course, you probably want to use ISOLINUX instead.  See the
+documentation file
+.BR isolinux.doc .
+.SS Booting from a FAT partition on a hard disk
+\s-1SYSLINUX\s+1 can boot from a FAT filesystem partition on a hard
+disk (including FAT32). The installation procedure is identical to the
+procedure for installing it on a floppy, and should work under either
+DOS or Linux. To boot from a partition, \s-1SYSLINUX\s+1 needs to be
+launched from a Master Boot Record or another boot loader, just like
+DOS itself would. A sample master boot sector (\fBmbr.bin\fP) is
+included with \s-1SYSLINUX\s+1.
+.SH BUGS
+I would appreciate hearing of any problems you have with \s-1SYSLINUX\s+1.  I
+would also like to hear from you if you have successfully used \s-1SYSLINUX\s+1,
+especially if you are using it for a distribution.
+.PP
+If you are reporting problems, please include all possible information
+about your system and your BIOS; the vast majority of all problems
+reported turn out to be BIOS or hardware bugs, and I need as much
+information as possible in order to diagnose the problems.
+.PP

+announcements of new and test versions. To join, send a message to

+   Inflate deflated (PKZIP's method 8 compressed) data.  The compression
+   method searches for as much of the current string of bytes (up to a
+   length of 258) in the previous 32 K bytes.  If it doesn't find any
+   matches (of at least length 3), it codes the next byte.  Otherwise, it
+   codes the length of the matched string and its distance backwards from
+   the current position.  There is a single Huffman code that codes both
+   single bytes (called "literals") and match lengths.  A second Huffman
+   code codes the distance information, which follows a length code.  Each
+   length or distance code actually represents a base value and a number
+   of "extra" (sometimes zero) bits to get to add to the base value.  At
+   the end of each deflated block is a special end-of-block (EOB) literal/
+   length code.  The decoding process is basically: get a literal/length
+   code; if EOB then done; if a literal, emit the decoded byte; if a
+   length then get the distance and emit the referred-to bytes from the
+   sliding window of previously emitted data.
+
+   There are (currently) three kinds of inflate blocks: stored, fixed, and
+   dynamic.  The compressor deals with some chunk of data at a time, and
+   decides which method to use on a chunk-by-chunk basis.  A chunk might
+   typically be 32 K or 64 K.  If the chunk is incompressible, then the
+   "stored" method is used.  In this case, the bytes are simply stored as
+   is, eight bits per byte, with none of the above coding.  The bytes are
+   preceded by a count, since there is no longer an EOB code.
+
+   If the data is compressible, then either the fixed or dynamic methods
+   are used.  In the dynamic method, the compressed data is preceded by
+   an encoding of the literal/length and distance Huffman codes that are
+   to be used to decode this block.  The representation is itself Huffman
+   coded, and so is preceded by a description of that code.  These code
+   descriptions take up a little space, and so for small blocks, there is
+   a predefined set of codes, called the fixed codes.  The fixed method is
+   used if the block codes up smaller that way (usually for quite small
+   chunks), otherwise the dynamic method is used.  In the latter case, the
+   codes are customized to the probabilities in the current block, and so
+   can code it much better than the pre-determined fixed codes.
+
+   The Huffman codes themselves are decoded using a multi-level table
+   lookup, in order to maximize the speed of decoding plus the speed of
+   building the decoding tables.  See the comments below that precede the
+   lbits and dbits tuning parameters.
+ */
+
+/*
+   Notes beyond the 1.93a appnote.txt:
+
+   1. Distance pointers never point before the beginning of the output
+      stream.
+   2. Distance pointers can point back across blocks, up to 32k away.
+   3. There is an implied maximum of 7 bits for the bit length table and
+      15 bits for the actual data.
+   4. If only one code exists, then it is encoded using one bit.  (Zero
+      would be more efficient, but perhaps a little confusing.)  If two
+      codes exist, they are coded using one bit each (0 and 1).
+   5. There is no way of sending zero distance codes--a dummy must be
+      sent if there are none.  (History: a pre 2.0 version of PKZIP would
+      store blocks with no distance codes, but this was discovered to be
+      too harsh a criterion.)  Valid only for 1.93a.  2.04c does allow
+      zero distance codes, which is sent as one code of zero bits in
+      length.
+   6. There are up to 286 literal/length codes.  Code 256 represents the
+      end-of-block.  Note however that the static length tree defines
+      288 codes just to fill out the Huffman codes.  Codes 286 and 287
+      cannot be used though, since there is no length base or extra bits
+      defined for them.  Similarly, there are up to 30 distance codes.
+      However, static trees define 32 codes (all 5 bits) to fill out the
+      Huffman codes, but the last two had better not show up in the data.
+   7. Unzip can check dynamic Huffman blocks for complete code sets.
+      The exception is that a single code would not be complete (see #4).
+   8. The five bits following the block type is really the number of
+      literal codes sent minus 257.
+   9. Length codes 8,16,16 are interpreted as 13 length codes of 8 bits
+      (1+6+6).  Therefore, to output three times the length, you output
+      three codes (1+1+1), whereas to output four times the same length,
+      you only need two codes (1+3).  Hmm.
+  10. In the tree reconstruction algorithm, Code = Code + Increment
+      only if BitLength(i) is not zero.  (Pretty obvious.)
+  11. Correction: 4 Bits: # of Bit Length codes - 4     (4 - 19)
+  12. Note: length code 284 can represent 227-258, but length code 285
+      really is 258.  The last length deserves its own, short code
+      since it gets used a lot in very redundant files.  The length
+      258 is special since 258 - 3 (the min match length) is 255.
+  13. The literal/length and distance code bit lengths are read as a
+      single stream of lengths.  It is possible (and advantageous) for
+      a repeat code (16, 17, or 18) to go across the boundary between
+      the two sets of lengths.

+   (The EOB code is shorter than other codes because fixed blocks are
+   generally short.  So, while a block always has an EOB, many other
+   literal/length codes have a significantly lower probability of
+   showing up at all.)  However, by making the first table have a

+   Huffman code decoding is performed using a multi-level table lookup.
+   The fastest way to decode is to simply build a lookup table whose
+   size is determined by the longest code.  However, the time it takes
+   to build this table can also be a factor if the data being decoded
+   is not very long.  The most common codes are necessarily the
+   shortest codes, so those codes dominate the decoding time, and hence
+   the speed.  The idea is you can have a shorter table that decodes the
+   shorter, more probable codes, and then point to subsidiary tables for
+   the longer codes.  The time it costs to decode the longer codes is
+   then traded against the time it takes to make longer tables.
+
+   This results of this trade are in the variables lbits and dbits
+   below.  lbits is the number of bits the first level table for literal/
+   length codes can decode in one step, and dbits is the same thing for
+   the distance codes.  Subsequent tables are also less than or equal to
+   those sizes.  These values may be adjusted either when all of the
+   codes are shorter than that, in which case the longest code length in
+   bits is used, or when the shortest code is *longer* than the requested
+   table size, in which case the length of the shortest code in bits is
+   used.
+
+   There are two different values for the two tables, since they code a
+   different number of possibilities each.  The literal/length table
+   codes 286 possible values, or in a flat code, a little over eight
+   bits.  The distance table codes 30 possible values, or a little less
+   than five bits, flat.  The optimum values for speed end up being
+   about one bit more than those, so lbits is 8+1 and dbits is 5+1.
+   The optimum values may differ though from machine to machine, and
+   possibly even between compilers.  Your mileage may vary.
