+		    GNU GENERAL PUBLIC LICENSE
+		       Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+                          675 Mass Ave, Cambridge, MA 02139, 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
+
+	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.

+This package contains a reimplementation of getopt(1).
+
+PREFACE
+
+Getopt(1) is a program to help shell scripts parse command-line parameters.
+It is for example included in the util-linux distribution (upto version
+2.7.1). But, there are some problems with that getopt(1) implementation, 
+as listed in the 'BUGS' section of its man-page:
+
+>BUGS
+>     Whatever getopt(3) has.
+>
+>     Arguments containing white space or imbedded shell metacharacters gener-
+>     ally will not survive intact;  this looks easy to fix but isn't.
+>
+>     The error message for an invalid option is identified as coming from
+>     getopt rather than from the shell procedure containing the invocation of
+>     getopt; this again is hard to fix.
+>
+>     The precise best way to use the set command to set the arguments without
+>     disrupting the value(s) of shell options varies from one shell version to
+>     another.
+
+This implementation of getopt(1) is written to solve some of these problems,
+while still staying (for all practical purposes) completely compatible with
+other getopt(1) implementations.
+
+
+INSTALLATION
+
+Installation should be very easy. Just type 'make' to compile the sources.
+It should compile cleanly, without any warnings, but even if it does not
+you probably don't have to worry. You must use GNU Make and gcc, or you
+will have to edit the Makefile. 
+
+Type 'make install' to install the binary and the manual page. It installs 
+by default in /usr/local/bin and /usr/local/man/man1, to install in /usr/bin 
+and /usr/man/man1 try 'make install prefix=/usr'.
+
+The example files can be installed in /usr/local/lib/getopt by calling
+'make install_doc'.
+
+If you do not trust the getopt(3) in your libc, or if you do not use a libc
+with the GNU getopt(3) routines, you can use the gnu sources as provided 
+in the gnu directory. Try 'make LIBCGETOPT=0'. Ignore any compile warnings.
+
+You can check whether the new implementation of getopt is found first
+in your path by calling 'bash test.bash'.
+
+
+HIGHLIGHTS
+
+It can do anything that the GNU getopt(3) routines can do.
+
+It can cope with spaces and shell metacharacters within arguments.
+
+It can parse long parameters.
+
+It can shuffle parameters, so you can mix options and other parameters on
+the command-line.
+
+It can be easily identified as an enhanced getopt(1) from within shell scripts.
+
+It can report parse errors as coming from the shell script.
+
+It is fully compatible with other getopt(1) implementations.
+
+COPYING

+file COPYING included in this package. Note that though you may freely
+copy it, it is copyright (c) 1997 by Frodo Looijaard <frodol@dds.nl>.

+.TH GETOPT 1 "May 31, 1997" Linux ""
+.SH NAME
+getopt \- parse command options (enhanced)
+.SH SYNOPSIS
+.BR getopt " optstring parameters"
+
+.BR getopt " [options] [" \-\- "] optstring parameters"
+
+.BR getopt " [options] " \-o | \-\-options " optstring [options] [" \-\- "] parameters"
+.SH DESCRIPTION
+.B getopt
+is used to break up 
+.RI ( parse )
+options in command lines for easy parsing by
+shell procedures, and to check for legal options.
+It uses the 
+.SM GNU
+.BR getopt (3) 
+routines to do this.
+
+The parameters 
+.B getopt
+is called with can be divided into two parts: options
+which modify the way getopt will parse
+.RI ( options
+and
+.I \-o|\-\-options optstring
+in the 
+.BR SYNOPSIS), 
+and the parameters which are to be
+parsed
+.RI ( parameters
+in the 
+.BR SYNOPSIS).
+The second part will start at the first non\-option parameter
+that is not an option argument, or after the first occurence of 
+.RB ` \-\- '.
+If no 
+.RB ` \-o ' 
+or 
+.RB ` \-\-options ' 
+option is found in the first part, the first
+parameter of the second part is used as the short options string.
+
+If the environment variable
+.B GETOPT_COMPATIBLE
+is set, or if its first parameter 
+is not an option (does not start with a
+.RB ` \- ',
+this is the first format in the 
+.BR SYNOPSIS),
+.B getopt
+will generate output that is compatible with that of other versions of 
+.BR getopt (1). 
+It will still do parameter shuffling and recognize optional
+arguments (see section
+.B COMPATIBILITY
+for more information). 
+
+Traditional implementations of
+.BR getopt (1)
+are unable to cope with whitespace and other (shell\-specific) special characters
+in arguments and non\-option parameters. To solve this problem, this 
+implementation can generate
+quoted output which must once again be interpreted by the shell (usually
+by using the
+.B eval
+command). This has the effect of preserving those characters, but
+you must call 
+.B getopt
+in a way that is no longer compatible with other versions (the second 
+or third format in the 
+.BR SYNOPSIS). 
+To determine whether this enhanced version of
+.BR getopt (1)
+is installed, a special test option
+.RB ( \-T ) 
+can be used.
+.SH OPTIONS
+.IP "\-a, \-\-alternative"
+Allow long options to start with a single 
+.RB ` \- '.
+.IP "\-h, \-\-help"
+Output a small usage guide and exit succesfully. No other output is generated. 
+.IP "\-l, \-\-longoptions longopts"
+The long (multi\-character) options to be recognized. 
+More than one option name
+may be specified at once, by separating the names with commas. This option 
+may be given more than once, the 
+.I longopts 
+are cumulative.
+Each long option name
+in 
+.I longopts 
+may be followed by one colon to indicate it has a required argument,and by two colons to indicate it has an optional argument.
+.IP "\-n, \-\-name progname"
+The name that will be used by the 
+.BR getopt (3)
+routines when it reports errors. Note that errors of
+.BR getopt (1)
+are still reported as coming from getopt.
+.IP "\-o, \-\-options shortopts"
+The short (one\-character) options to be recognized. If this option is not
+found, the first parameter of 
+.B getopt 
+that does not start with
+a 
+.RB ` \- ' 
+(and is not an option argument) is used as the short options string.
+Each short option character
+in 
+.I shortopts 
+may be followed by one colon to indicate it has a required argument,
+and by two colons to indicate it has an optional argument.
+The first character of shortopts may be 
+.RB ` + ' 
+or
+.RB ` \- ' 
+to influence the way
+options are parsed and output is generated (see section 
+.B SCANNING MODES
+for details).
+.IP "\-q, \-\-quiet"
+Disable error reporting by getopt(3).
+.IP "\-Q, \-\-quiet\-output"
+Do not generate normal output. Errors are still reported by
+.BR getopt (3), 
+unless you also use 
+.IR \-q .
+.IP "\-s, \-\-shell shell"
+Set quoting conventions to those of shell. If no \-s argument is found,
+the
+.SM BASH
+conventions are used. Valid arguments are currently
+.RB ` sh '
+.RB ` bash ',
+.RB ` csh ',
+and
+.RB ` tcsh '.
+.IP "\-u, \-\-unquoted"
+Do not quote the output. Note that whitespace and special (shell\-dependent)
+characters can cause havoc in this mode (like they do with other
+.BR getopt (1)
+implementations).
+.IP "\-T \-\-test"
+Test if your 
+.BR getopt (1) 
+is this enhanced version or an old version. This generates no output, 
+and sets the error status to 4. Other implementations of 
+.BR getopt (1),
+and this version if the environment variable
+.B GETOPT_COMPATIBLE
+is set,
+will return 
+.RB ` \-\- ' 
+and error status 0.
+.IP "\-V, \-\-version"
+Output version information and exit succesfully. No other output is generated. 
+.SH PARSING
+This section specifies the format of the second part of the parameters of
+.B getopt
+(the 
+.I parameters 
+in the 
+.BR SYNOPSIS ). 
+The next section 
+.RB ( OUTPUT ) 
+describes the output that is 
+generated. These parameters were typically the parameters a shell function
+was called with. 
+Care must be taken that each parameter the shell function was
+called with corresponds to exactly one parameter in the parameter list of
+.B getopt 
+(see the 
+.BR EXAMPLES ). 
+All parsing is done by the GNU 
+.BR getopt (3) 
+routines. 
+
+The parameters are parsed from left to right. Each parameter is classified as a
+short option, a long option, an argument to an option,
+or a non\-option parameter.
+
+A simple short option is a 
+.RB ` \- ' 
+followed by a short option character. If
+the option has a required argument, it may be written directly after the option
+character or as the next parameter (ie. separated by whitespace on the 
+command line). If the
+option has an optional argument, it must be written directly after the
+option character if present.
+
+It is possible to specify several short options after one 
+.RB ` \- ', 
+as long as all (except possibly the last) do not have required or optional
+arguments.
+
+A long option normally begins with 
+.RB ` \-\- ' 
+followed by the long option name.
+If the option has a required argument, it may be written directly after
+the long option name, separated by 
+.RB ` = ', 
+or as the next argument (ie. separated by whitespace on the command line). 
+If the option has an optional argument, it must
+be written directly after the long option name, separated by 
+.RB ` = ', 
+if present (if you add the 
+.RB ` = ' 
+but nothing behind it, it is interpreted
+as if no argument was present; this is a slight bug, see the 
+.BR BUGS ).
+Long options may be abbreviated, as long as the abbreviation is not
+ambiguous.
+
+Each parameter not starting with a 
+.RB ` \- ', 
+and not a required argument of
+a previous option, is a non\-option parameter. Each parameter after
+a 
+.RB ` \-\- ' 
+parameter is always interpreted as a non\-option parameter.
+If the environment variable 
+.B POSIXLY_CORRECT 
+is set, or if the short
+option string started with a 
+.RB ` + ', 
+all remaining parameters are interpreted
+as non\-option parameters as soon as the first non\-option parameter is
+found.
+.SH OUTPUT
+Output is generated for each element described in the previous section. 
+Output is done
+in the same order as the elements are specified in the input, except
+for non\-option parameters. Output can be done in 
+.I compatible 
+.RI ( unquoted )
+mode, or in such way that whitespace and other special characters within
+arguments and non\-option parameters are preserved (see 
+.BR QUOTING ).
+When the output is processed in the shell script, it will seem to be
+composed of distinct elements that can be processed one by one (by using the
+shift command in most shell languages). This is imperfect in unquoted mode,
+as elements can be split at unexpected places if they contain whitespace
+or special characters.
+
+If there are problems parsing the parameters, for example because a
+required argument is not found or an option is not recognized, an error
+will be reported on stderr, there will be no output for the offending
+element, and a non\-zero error status is returned.
+
+For a short option, a single 
+.RB ` \- ' 
+and the option character are generated
+as one parameter. If the option has an argument, the next
+parameter will be the argument. If the option takes an optional argument,
+but none was found, the next parameter will be generated but be empty in
+quoting mode,
+but no second parameter will be generated in unquoted (compatible) mode.
+Note that many other 
+.BR getopt (1) 
+implemetations do not support optional arguments.
+
+If several short options were specified after a single 
+.RB ` \- ', 
+each will be present in the output as a separate parameter.
+
+For a long option, 
+.RB ` \-\- ' 
+and the full option name are generated as one
+parameter. This is done regardless whether the option was abbreviated or
+specified with a single 
+.RB ` \- ' 
+in the input. Arguments are handled as with short options.
+
+Normally, no non\-option parameters output is generated until all options
+and their arguments have been generated. Then 
+.RB ` \-\- ' 
+is generated as a
+single parameter, and after it the non\-option parameters in the order
+they were found, each as a separate parameter.
+Only if the first character of the short options string was a 
+.RB ` \- ',
+non\-option parameter output is generated at the place they are found in the 
+input (this is not supported if the first format of the 
+.B SYNOPSIS
+is used; in that case all preceding occurences of
+.RB ` \- '
+and 
+.RB ` + '
+are ignored). 
+.SH QUOTING
+In compatible mode, whitespace or 'special' characters in arguments or
+non\-option parameters are not handled correctly. As the output is 
+fed to the shell script, the script does not know how it is supposed to break 
+the output into separate parameters.  To circumvent this
+problem, this implementation offers quoting. The idea is that output
+is generated with quotes around each parameter. When this output is once
+again fed to the shell (usually by a shell 
+.B eval 
+command), it is split correctly into separate parameters.
+
+Quoting is not enabled if the environment variable
+.B GETOPT_COMPATIBLE
+is set, if the first form of the
+.B SYNOPSIS
+is used, or if the option
+.RB ` \-u '
+is found.
+
+Different shells use different quoting conventions. You can use the 
+.RB ` \-s '
+option to select the shell you are using. The following shells are
+currently supported:
+.RB ` sh ',
+.RB ` bash ',
+.RB ` csh ' 
+and
+.RB ` tcsh '.
+Actually, only two `flavors' are distinguished: sh\-like quoting conventions 
+and csh\-like quoting conventions. Chances are that if you use another shell
+script language, one of these flavors can still be used.
+
+.SH "SCANNING MODES"
+The first character of the short options string may be a
+.RB ` \- '
+or a
+.RB ` + '
+to indicate a special scanning mode. If the first calling form
+in the
+.B SYNOPSIS 
+is used they are ignored; the environment variable
+.B POSIXLY_CORRECT
+is still examined, though.
+
+If the first character is 
+.RB ` + ',
+or if the environment variable 
+.B POSIXLY_CORRECT
+is set, parsing stops as soon as the first non\-option parameter 
+(ie. a parameter that does not start with a 
+.RB ` \- ')
+is found that
+is not an option argument. The remaining parameters are all interpreted as
+non\-option parameters.
+
+If the first character is a
+.RB ` \- ',
+non\-option parameters are outputed at the place where they are found; in normal
+operation, they are all collected at the end of output after a 
+.RB ` \-\- ' 
+parameter has been generated. Note that this
+.RB ` \-\- '
+parameter is still generated, but it will always be the last parameter in
+this mode.
+.SH COMPATIBILITY
+This version of 
+.BR getopt (1)
+is written to be as compatible as possible to 
+other versions. Usually you can just replace them with this version
+without any modifications, and with some advantages.
+
+If the first character of the first parameter of getopt is not a 
+.RB ` \- ', 
+getopt goes into compatibility mode. It will interpret its first parameter as
+the string of short options, and all other arguments will be parsed. It
+will still do parameter shuffling (ie. all non\-option parameters are outputed
+at the end), unless the environment variable 
+.B POSIXLY_CORRECT 
+is set.
+
+The environment variable 
+.B GETOPT_COMPATIBLE 
+forces 
+.B getopt
+into compatibility mode. Setting both this environment variable and
+.B POSIXLY_CORRECT
+offers 100% compatibility for `difficult' programs. Usually, though,
+neither is needed.
+
+In compatibility mode, leading 
+.RB ` \- '
+and 
+.RB ` + '
+characters in the short options string are ignored.
+.SH RETURN CODES
+.B getopt
+returns error code 
+.B 0 
+for succesful parsing, 
+.B 1
+if
+.BR getopt (3)
+returns errors,
+.B 2 
+if it does not understand its own parameters,
+.B 3
+if an internal error occurs like out\-of\-memory, and
+.B 4
+if it is called with 
+.BR \-T .
+.SH EXAMPLES
+Example scripts for (ba)sh and (t)csh are provided with the
+.BR getopt (1)
+distribution, and are optionally installed in 
+.B /usr/local/lib/getopt 
+or 
+.BR /usr/lib/getopt .
+.SH ENVIRONMENT
+.IP POSIXLY_CORRECT
+This environment variable is examined by the
+.BR getopt (3)
+routines.
+If it is set, parsing stops as soon as a parameter
+is found that is not an option or an option argument. All remaining 
+parameters are also interpreted as non\-option parameters, regardless
+whether they start with a 
+.RB ` \- '.
+.IP GETOPT_COMPATIBLE
+Forces
+.B getopt
+to use the first calling format as specified in the
+.BR SYNOPSIS .
+.SH BUGS
+.BR getopt (3)
+can parse long options with optional arguments that are given an empty optional
+argument (but can not do this for short options). This 
+.BR getopt (1)
+treats optional arguments that are empty as if they were not present.
+
+The syntax if you do not want any short option variables at all is
+not very intuitive (you have to set them explicitely to the empty
+string).

+/* Scan elements of ARGV (whose length is ARGC) for option characters
+   given in OPTSTRING.
+
+   If an element of ARGV starts with '-', and is not exactly "-" or "--",
+   then it is an option element.  The characters of this element
+   (aside from the initial '-') are option characters.  If `getopt'
+   is called repeatedly, it returns successively each of the option characters
+   from each of the option elements.
+
+   If `getopt' finds another option character, it returns that character,
+   updating `optind' and `nextchar' so that the next call to `getopt' can
+   resume the scan with the following option character or ARGV-element.
+
+   If there are no more option characters, `getopt' returns -1.
+   Then `optind' is the index in ARGV of the first ARGV-element
+   that is not an option.  (The ARGV-elements have been permuted
+   so that those that are not options now come last.)
+
+   OPTSTRING is a string containing the legitimate option characters.
+   If an option character is seen that is not listed in OPTSTRING,
+   return '?' after printing an error message.  If you set `opterr' to
+   zero, the error message is suppressed but we still return '?'.
+
+   If a char in OPTSTRING is followed by a colon, that means it wants an arg,
+   so the following text in the same ARGV-element, or the text of the following
+   ARGV-element, is returned in `optarg'.  Two colons mean an option that
+   wants an optional arg; if there is text in the current ARGV-element,
+   it is returned in `optarg', otherwise `optarg' is set to zero.
+
+   If OPTSTRING starts with `-' or `+', it requests different methods of
+   handling the non-option ARGV-elements.
+   See the comments about RETURN_IN_ORDER and REQUIRE_ORDER, above.
+
+   Long-named options begin with `--' instead of `-'.
+   Their names may be abbreviated as long as the abbreviation is unique
+   or is an exact match for some defined option.  If they have an
+   argument, it follows the option name in the same ARGV-element, separated
+   from the option name by a `=', or else the in next ARGV-element.
+   When `getopt' finds a long-named option, it returns 0 if that option's
+   `flag' field is nonzero, the value of the option's `val' field
+   if the `flag' field is zero.
+
+   The elements of ARGV aren't really const, because we permute them.
+   But we pretend they're const in the prototype to be compatible
+   with other systems.
+
+   LONGOPTS is a vector of `struct option' terminated by an
+   element containing a name which is zero.
+
+   LONGIND returns the index in LONGOPT of the long-named option found.
+   It is only valid when a long-named option has been found by the most
+   recent call.
+
+   If LONG_ONLY is nonzero, '-' as well as '--' can introduce
+   long-named options.  */
