+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
+into C code which can then be compiled into a .c32 file for use with SYSLINUX.
+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.
+
+Credits
+-------
+* The Watcom developers and Peter Anvin for figuring out an OS
+  independent startup code.
+* Thomas for porting the crypt function and removing all C library
+  dependencies
+* Peter Anvin for porting the code to GCC
