+# This script is used to configure the Linux kernel.
+#
+# It was inspired by the challenge in the original Configure script
+# to ``do something better'', combined with the actual need to ``do
+# something better'' because the old configure script wasn't flexible
+# enough.
+#
+# Raymond Chen was the original author of Configure.
+# Michael Elizabeth Chastain (mec@shout.net) is the current maintainer.
+#
+# 050793 - use IFS='@' to get around a bug in a pre-version of bash-1.13
+# with an empty IFS.
+#
+# 030995 (storner@osiris.ping.dk) - added support for tri-state answers,
+# for selecting modules to compile.
+#
+# 180995 Bernhard Kaindl (bkaindl@ping.at) - added dummy functions for
+# use with a config.in modified for make menuconfig.
+#
+# 301195 (boldt@math.ucsb.edu) - added help text support
+#
+# 281295 Paul Gortmaker - make tri_state functions collapse to boolean
+# if module support is not enabled.
+#
+# 010296 Aaron Ucko (ucko@vax1.rockhurst.edu) - fix int and hex to accept
+# arbitrary ranges
+#
+# 150296 Dick Streefland (dicks@tasking.nl) - report new configuration
+# items and ask for a value even when doing a "make oldconfig"
+#
+# 200396 Tom Dyas (tdyas@eden.rutgers.edu) - when the module option is
+# chosen for an item, define the macro <option_name>_MODULE
+#
+# 090397 Axel Boldt (boldt@math.ucsb.edu) - avoid ? and + in regular 
+# expressions for GNU expr since version 1.15 and up use \? and \+.
+#
+# 300397 Phil Blundell (pjb27@cam.ac.uk) - added support for min/max 
+# arguments to "int", allow dep_tristate to take a list of dependencies
+# rather than just one.
+#
+# 090398 Axel Boldt (boldt@math.ucsb.edu) - allow for empty lines in help
+# texts.
+#
+# 102598 Michael Chastain (mec@shout.net) - put temporary files in
+# current directory, not in /tmp.
+#
+# 24 January 1999, Michael Elizabeth Chastain, <mec@shout.net>
+# - Improve the exit message (Jeff Ronne).
+
+#
+# Make sure we're really running bash.

+# 070497 Bernhard Kaindl (bkaindl@netway.at) - get default values for
+# new bool, tristate and dep_tristate parameters from the defconfig file.
+# new configuration parameters are marked with '(NEW)' as in make config.
+#
+# 180697 Bernhard Kaindl (bkaindl@netway.at) - added the needed support
+# for string options. They are handled like the int and hex options.
+#
+# 081297 Pavel Machek (pavel@atrey.karlin.mff.cuni.cz) - better error 
+# handling
+#
+# 131197 Michael Chastain (mec@shout.net) - output all lines for a
+# choice list, not just the selected one.  This makes the output
+# the same as Configure output, which is important for smart config
+# dependencies.
+#
+# 101297 Michael Chastain (mec@shout.net) - remove sound driver cruft.
+#
+# 221297 Michael Chastain (mec@shout.net) - make define_bool actually
+# define its arguments so that later tests on them work right.
+#
+# 160198 Michael Chastain (mec@shout.net) - fix bug with 'c' command
+# (complement existing value) when used on virgin uninitialized variables.
+#
+# 090398 Axel Boldt (boldt@math.ucsb.edu) - allow for empty lines in help
+# texts.
+#
+# 12 Dec 1998, Michael Elizabeth Chastain (mec@shout.net)
+# Remove a /tmp security hole in get_def (also makes it faster).
+# Give uninitialized variables canonical values rather than null value.
+# Change a lot of places to call set_x_info uniformly.
+# Take out message about preparing version (old sound driver cruft).

+# Fix mod_bool to honor $CONFIG_MODULES.
+# Fix dep_tristate to call define_bool when dependency is "n".
+#
+# 02 January 1999, Michael Elizabeth Chastain (mec@shout.net)
+# Blow away lxdialog.scrltmp on entry to activate_menu.  This protects
+# against people who use commands like ' ' to select menus.
+#
+# 24 January 1999, Michael Elizabeth Chastain, <mec@shout.net>
+# - Improve the exit message (Jeff Ronne).
+#
+# 06 July 1999, Andrzej M. Krzysztofowicz, <ankry@mif.pg.gda.pl>
+# - Support for multiple conditions in dep_tristate().
+# - Implemented new functions: define_tristate(), define_int(), define_hex(),

+
+There seems to be a problem with the lxdialog companion utility which is
+built prior to running Menuconfig.  Usually this is an indicator that you
+have upgraded/downgraded your ncurses libraries and did not remove the 
+old ncurses header file(s) in /usr/include or /usr/include/ncurses.
+
+It is VERY important that you have only one set of ncurses header files
+and that those files are properly version matched to the ncurses libraries 
+installed on your machine.
+
+You may also need to rebuild lxdialog.  This can be done by moving to
+the /usr/src/linux/scripts/lxdialog directory and issuing the 
+"make clean all" command.
+
+If you have verified that your ncurses install is correct, you may email
+the maintainer <mec@shout.net> or post a message to
+<linux-kernel@vger.kernel.org> for additional assistance.

+Menuconfig gives the Linux kernel configuration a long needed face
+lift.  Featuring text based color menus and dialogs, it does not
+require X Windows.  With this utility you can easily select a kernel
+option to modify without sifting through 100 other options.
+
+Overview
+--------
+Some kernel features may be built directly into the kernel.
+Some may be made into loadable runtime modules.  Some features
+may be completely removed altogether.  There are also certain
+kernel parameters which are not really features, but must be 
+entered in as decimal or hexadecimal numbers or possibly text.
+
+Menu items beginning with [*], <M> or [ ] represent features 
+configured to be built in, modularized or removed respectively.
+Pointed brackets <> represent module capable features.
+                                                             more...
+
+To change any of these features, highlight it with the cursor 
+keys and press <Y> to build it in, <M> to make it a module or
+<N> to removed it.  You may also press the <Space Bar> to cycle
+through the available options (ie. Y->N->M->Y). 
+
+Items beginning with numbers or other text within parenthesis can 
+be changed by highlighting the item and pressing <Enter>.  Then
+enter the new parameter into the dialog box that pops up.
+
+
+Some additional keyboard hints:
+
+Menus
+----------
+o  Use the Up/Down arrow keys (cursor keys) to highlight the item 
+   you wish to change or submenu wish to select and press <Enter>.
+   Submenus are designated by "--->".
+
+   Shortcut: Press the option's highlighted letter (hotkey).
+             Pressing a hotkey more than once will sequence
+             through all visible items which use that hotkey.
+
+   You may also use the <PAGE UP> and <PAGE DOWN> keys to scroll
+   unseen options into view.
+
+o  To exit a menu use the cursor keys to highlight the <Exit> button
+   and press <ENTER>.  
+
+   Shortcut: Press <ESC><ESC> or <E> or <X> if there is no hotkey
+             using those letters.  You may press a single <ESC>, but
+             there is a delayed response which you may find annoying.
+
+   Also, the <TAB> and cursor keys will cycle between <Select>,
+   <Exit> and <Help>
+
+o  To get help with an item, use the cursor keys to highlight <Help>
+   and Press <ENTER>.
+
+   Shortcut: Press <H> or <?>.
+
+
+Radiolists  (Choice lists)
+-----------
+o  Use the cursor keys to select the option you wish to set and press
+   <S> or the <SPACE BAR>.
+
+   Shortcut: Press the first letter of the option you wish to set then
+             press <S> or <SPACE BAR>.
+
+o  To see available help for the item, use the cursor keys to highlight
+   <Help> and Press <ENTER>.
+
+   Shortcut: Press <H> or <?>.
+
+   Also, the <TAB> and cursor keys will cycle between <Select> and
+   <Help>
+
+
+Data Entry
+-----------
+o  Enter the requested information and press <ENTER>
+   If you are entering hexadecimal values, it is not necessary to
+   add the '0x' prefix to the entry.
+
+o  For help, use the <TAB> or cursor keys to highlight the help option
+   and press <ENTER>.  You can try <TAB><H> as well.
+
+
+Text Box    (Help Window)
+--------
+o  Use the cursor keys to scroll up/down/left/right.  The VI editor
+   keys h,j,k,l function here as do <SPACE BAR> and <B> for those
+   who are familiar with less and lynx.
+
+o  Press <E>, <X>, <Enter> or <Esc><Esc> to exit.
+
+
+Final Acceptance
+----------------
+With the exception of the old style sound configuration,
+YOUR CHANGES ARE NOT FINAL.  You will be given a last chance to
+confirm them prior to exiting Menuconfig.
+
+If Menuconfig quits with an error while saving your configuration,
+you may look in the file /usr/src/linux/.menuconfig.log for
+information which may help you determine the cause.
+
+Alternate Configuration Files
+-----------------------------
+Menuconfig supports the use of alternate configuration files for
+those who, for various reasons, find it necessary to switch 
+between different kernel configurations.
+
+At the end of the main menu you will find two options.  One is
+for saving the current configuration to a file of your choosing.
+The other option is for loading a previously saved alternate
+configuration.
+
+Even if you don't use alternate configuration files, but you 
+find during a Menuconfig session that you have completely messed
+up your settings, you may use the "Load Alternate..." option to
+restore your previously saved settings from ".config" without 
+restarting Menuconfig.
+
+Other information
+-----------------
+The windowing utility, lxdialog, will only be rebuilt if your kernel
+source tree is fresh, or changes are patched into it via a kernel
+patch or you do 'make mrproper'.  If changes to lxdialog are patched
+in, most likely the rebuild time will be short.  You may force a
+complete rebuild of lxdialog by changing to it's directory and doing
+'make clean all'
+
+If you use Menuconfig in an XTERM window make sure you have your 
+$TERM variable set to point to a xterm definition which supports color.
+Otherwise, Menuconfig will look rather bad.  Menuconfig will not 
+display correctly in a RXVT window because rxvt displays only one
+intensity of color, bright.
+
+Menuconfig will display larger menus on screens or xterms which are
+set to display more than the standard 25 row by 80 column geometry.
+In order for this to work, the "stty size" command must be able to 
+display the screen's current row and column geometry.  I STRONGLY
+RECOMMEND that you make sure you do NOT have the shell variables
+LINES and COLUMNS exported into your environment.  Some distributions
+export those variables via /etc/profile.  Some ncurses programs can
+become confused when those variables (LINES & COLUMNS) don't reflect
+the true screen size.
+
+
+NOTICE:  lxdialog requires the ncurses libraries to compile.  If you
+         don't already have ncurses you really should get it.
+
+         The makefile for lxdialog attempts to find your ncurses
+         header file.  Although it should find the header for older
+         versions of ncurses, it is probably a good idea to get the
+         latest ncurses anyway. 
+
+         If you have upgraded your ncurses libraries, MAKE SURE you
+         remove the old ncurses header files.  If you don't you
+         will most certainly get a segmentation fault.

+WARNING: It is not recommended that you change any defines in
+         lxdialog's header files.  If you have a grayscale display and
+         are brave, you may tinker with color.h to tune the colors to
+         your preference.
+
+COMPATIBILITY ISSUE:
+         There have been some compatibility problems reported with
+         older versions of bash and sed.  I am trying to work these
+         out but it is preferable that you upgrade those utilities.
+
+
+******** IMPORTANT, OPTIONAL ALTERNATE PERSONALITY AVAILABLE ********
+********                                                     ********
+If you prefer to have all of the kernel options listed in a single
+menu, rather than the default multimenu hierarchy, you may edit the
+Menuconfig script and change the line "single_menu_mode="  to 
+"single_menu_mode=TRUE".
+
+This mode is not recommended unless you have a fairly fast machine.

+The windowing support utility (lxdialog) is a VERY modified version of
+the dialog utility by Savio Lam <lam836@cs.cuhk.hk>.  Although lxdialog
+is significantly different from dialog, I have left Savio's copyrights
+intact.  Please DO NOT contact Savio with questions about lxdialog.
+He will not be able to assist.

+# =======
+#
+# 8 January 1999, Michael Elizabeth Chastain, <mec@shout.net>
+# - Remove unused do_cmd function (part of the 2.0 sound support).
+# - Arrange buttons in three columns for better screen fitting.
+# - Add CONSTANT_Y, CONSTANT_M, CONSTANT_N for commands like:
+#     dep_tristate 'foo' CONFIG_FOO m
+#
+# 23 January 1999, Michael Elizabeth Chastain, <mec@shout.net>
+# - Shut vfix the hell up.
+#
+# 24 January 1999, Michael Elizabeth Chastain, <mec@shout.net>
+# - Improve the exit message (Jeff Ronne).
+
+#
+# This is a handy replacement for ".widget cget" that requires neither tk4
+# nor additional source code uglification.
+#

+# 		Functions prototyped as foo(void) same as foo()
+# 		Stop eval'ing where we don't need to.
+# -- huggie@earth.li
+
+# 27/06/2001 -  Allowed whitespace after initial "/**" and
+#               allowed comments before function declarations.
+# -- Christian Kreibich <ck@whoop.org>
+
+# Still to do:
+# 	- add perldoc documentation
+# 	- Look more closely at some of the scarier bits :)
+
+# 26/05/2001 - 	Support for separate source and object trees.
+#		Return error code.
+# 		Keith Owens <kaos@ocs.com.au>
+
+# 23/09/2001 - Added support for typedefs, structs, enums and unions
+#              Support for Context section; can be terminated using empty line
+#              Small fixes (like spaces vs. \s in regex)

+# This will read a 'c' file and scan for embedded comments in the
+# style of gnome comments (+minor extensions - see below).
+#
+
+# Note: This only supports 'c'.
+
+# usage:
+# kerneldoc [ -docbook | -html | -text | -man ]
+#           [ -function funcname [ -function funcname ...] ] c file(s)s > outputfile
+# or
+#           [ -nofunction funcname [ -function funcname ...] ] c file(s)s > outputfile
+#
+#  Set output format using one of -docbook -html -text or -man.  Default is man.
+#
+#  -function funcname
+#	If set, then only generate documentation for the given function(s).  All
+#	other functions are ignored.
+#
+#  -nofunction funcname
+#	If set, then only generate documentation for the other function(s).  All
+#	other functions are ignored. Cannot be used with -function together
+#	(yes thats a bug - perl hackers can fix it 8))
+#
+#  c files - list of 'c' files to process
+#
+#  All output goes to stdout, with errors to stderr.
+
+#
+# format of comments.
+# In the following table, (...)? signifies optional structure.
+#                         (...)* signifies 0 or more structure elements
+# /**
+#  * function_name(:)? (- short description)?
+# (* @parameterx: (description of parameter x)?)*
+# (* a blank line)?
+#  * (Description:)? (Description of function)?
+#  * (section header: (section description)? )*
+#  (*)?*/
+#
+# So .. the trivial example would be:
+#
+# /**
+#  * my_function
+#  **/
+#
+# If the Description: header tag is ommitted, then there must be a blank line
+# after the last parameter specification.
+# e.g.
+# /**
+#  * my_function - does my stuff
+#  * @my_arg: its mine damnit
+#  *
+#  * Does my stuff explained. 
+#  */
+#
+#  or, could also use:
+# /**
+#  * my_function - does my stuff
+#  * @my_arg: its mine damnit
+#  * Description: Does my stuff explained. 
+#  */
+# etc.
+#
+# Beside functions you can also write documentation for structs, unions, 
+# enums and typedefs. Instead of the function name you must write the name 
+# of the declaration;  the struct/union/enum/typedef must always precede 
+# the name. Nesting of declarations is not supported. 
+# Use the argument mechanism to document members or constants. In 
+# structs and unions you must declare one member per declaration 
+# (comma-separated members are not allowed -  the parser does not support 
+# this).
+# e.g.
+# /**
+#  * struct my_struct - short description
+#  * @a: first member
+#  * @b: second member
+#  * 
+#  * Longer description
+#  */
+# struct my_struct {
+#     int a;
+#     int b;
+# };
+#
+# All descriptions can be multiline, except the short function description.
+# 
+# You can also add additional sections. When documenting kernel functions you 
+# should document the "Context:" of the function, e.g. whether the functions 
+# can be called form interrupts. Unlike other sections you can end it with an
+# empty line. 
+# Example-sections should contain the string EXAMPLE so that they are marked 
+# appropriately in DocBook.
+#
+# Example:
+# /**
+#  * user_function - function that can only be called in user context
+#  * @a: some argument
+#  * Context: !in_interrupt()
+#  * 
+#  * Some description
+#  * Example:
+#  *    user_function(22);
+#  */
+# ...
+#
+#
+# All descriptive text is further processed, scanning for the following special
+# patterns, which are highlighted appropriately.
+#
+# 'funcname()' - function
+# '$ENVVAR' - environmental variable

+ *  Changes by Clifford Wolf (god@clifford.at)
+ *
+ *  [ 1998-06-13 ]
+ *
+ *    *)  A bugfix for the Page-Down problem
+ *
+ *    *)  Formerly when I used Page Down and Page Up, the cursor would be set 
+ *        to the first position in the menu box.  Now lxdialog is a bit
+ *        smarter and works more like other menu systems (just have a look at
+ *        it).
+ *
+ *    *)  Formerly if I selected something my scrolling would be broken because
+ *        lxdialog is re-invoked by the Menuconfig shell script, can't
+ *        remember the last scrolling position, and just sets it so that the
+ *        cursor is at the bottom of the box.  Now it writes the temporary file
+ *        lxdialog.scrltmp which contains this information. The file is
+ *        deleted by lxdialog if the user leaves a submenu or enters a new
+ *        one, but it would be nice if Menuconfig could make another "rm -f"
+ *        just to be sure.  Just try it out - you will recognise a difference!
+ *
+ *  [ 1998-06-14 ]
+ *
+ *    *)  Now lxdialog is crash-safe against broken "lxdialog.scrltmp" files
+ *        and menus change their size on the fly.
+ *
+ *    *)  If for some reason the last scrolling position is not saved by
+ *        lxdialog, it sets the scrolling so that the selected item is in the
+ *        middle of the menu box, not at the bottom.
+ *
+ * 02 January 1999, Michael Elizabeth Chastain (mec@shout.net)
+ * Reset 'scroll' to 0 if the value from lxdialog.scrltmp is bogus.
+ * This fixes a bug in Menuconfig where using ' ' to descend into menus
+ * would leave mis-synchronized lxdialog.scrltmp files lying around,
+ * fscanf would read in 'scroll', and eventually that value would get used.

+ * Originally by Linus Torvalds.
+ * Smart CONFIG_* processing by Werner Almesberger, Michael Chastain.
+ *
+ * Usage: mkdep cflags -- file ...
+ * 
+ * Read source files and output makefile dependency lines for them.
+ * I make simple dependency lines for #include <*.h> and #include "*.h".
+ * I also find instances of CONFIG_FOO and generate dependencies
+ *    like include/config/foo.h.
+ *
+ * 1 August 1999, Michael Elizabeth Chastain, <mec@shout.net>
+ * - Keith Owens reported a bug in smart config processing.  There used
+ *   to be an optimization for "#define CONFIG_FOO ... #ifdef CONFIG_FOO",
+ *   so that the file would not depend on CONFIG_FOO because the file defines
+ *   this symbol itself.  But this optimization is bogus!  Consider this code:
+ *   "#if 0 \n #define CONFIG_FOO \n #endif ... #ifdef CONFIG_FOO".  Here
+ *   the definition is inactivated, but I still used it.  It turns out this
+ *   actually happens a few times in the kernel source.  The simple way to
+ *   fix this problem is to remove this particular optimization.
+ *
+ * 2.3.99-pre1, Andrew Morton <andrewm@uow.edu.au>
+ * - Changed so that 'filename.o' depends upon 'filename.[cS]'.  This is so that
+ *   missing source files are noticed, rather than silently ignored.
+ *
+ * 2.4.2-pre3, Keith Owens <kaos@ocs.com.au>
+ * - Accept cflags followed by '--' followed by filenames.  mkdep extracts -I
+ *   options from cflags and looks in the specified directories as well as the
+ *   defaults.   Only -I is supported, no attempt is made to handle -idirafter,
+ *   -isystem, -I- etc.

+ *   the output of the old tkparse.
+ *
+ * 07 July 1999, Andrzej M. Krzysztofowicz <ankry@mif.pg.gda.pl>
+ * - kvariables removed; all variables are stored in a single table now
+ * - some elimination of options non-valid for current architecture
+ *   implemented.
+ * - negation (!) eliminated from conditions
+ *
+ * TO DO:
+ * - xconfig is at the end of its life cycle.  Contact <mec@shout.net> if

+/* Generate tk script based upon config.in
+ *
+ * Version 1.0
+ * Eric Youngdale
+ * 10/95
+ *
+ * 1996 01 04
+ * Avery Pennarun - Aesthetic improvements.
+ *
+ * 1996 01 24
+ * Avery Pennarun - Bugfixes and more aesthetics.
+ *
+ * 1996 03 08
+ * Avery Pennarun - The int and hex config.in commands work right.
+ *                - Choice buttons are more user-friendly.
+ *                - Disabling a text entry line greys it out properly.
+ *                - dep_tristate now works like in Configure. (not pretty)
+ *                - No warnings in gcc -Wall. (Fixed some "interesting" bugs.)
+ *                - Faster/prettier "Help" lookups.
+ *
+ * 1996 03 15
+ * Avery Pennarun - Added new sed script from Axel Boldt to make help even
+ *                  faster. (Actually awk is downright slow on some machines.)
+ *                - Fixed a bug I introduced into Choice dependencies.  Thanks
+ *                  to Robert Krawitz for pointing this out.
+ *
+ * 1996 03 16
+ * Avery Pennarun - basic "do_make" support added to let sound config work.
+ *
+ * 1996 03 25
+ *     Axel Boldt - Help now works on "choice" buttons.
+ *
+ * 1996 04 06
+ * Avery Pennarun - Improved sound config stuff. (I think it actually works
+ *                  now!)
+ *                - Window-resize-limits don't use ugly /usr/lib/tk4.0 hack.
+ *                - int/hex work with tk3 again. (The "cget" error.)
+ *                - Next/Prev buttons switch between menus.  I can't take
+ *                  much credit for this; the code was already there, but
+ *                  ifdef'd out for some reason.  It flickers a lot, but
+ *                  I suspect there's no "easy" fix for that.
+ *                - Labels no longer highlight as you move the mouse over
+ *                  them (although you can still press them... oh well.)
+ *                - Got rid of the last of the literal color settings, to
+ *                  help out people with mono X-Windows systems. 
+ *                  (Apparently there still are some out there!)
+ *                - Tabstops seem sensible now.
+ *
+ * 1996 04 14
+ * Avery Pennarun - Reduced flicker when creating windows, even with "update
+ *                  idletasks" hack.
+ *
+ * 1997 12 08
+ * Michael Chastain - Remove sound driver special cases.
+ *
+ * 1997 11 15
+ * Michael Chastain - For choice buttons, write values for all options,
+ *                    not just the single chosen one.  This is compatible
+ *                    with 'make config' and 'make oldconfig', and is
+ *                    needed so smart-config dependencies work if the
+ *                    user switches from one configuration method to
+ *                    another.
+ *
+ * 1998 03 09
+ * Axel Boldt - Smaller layout of main menu - it's still too big for 800x600.
+ *            - Display help in text window to allow for cut and paste.
+ *            - Allow for empty lines in help texts.
+ *            - update_define should not set all variables unconditionally to
+ *              0: they may have been set to 1 elsewhere. CONFIG_NETLINK is
+ *              an example.
+ *
+ * 1999 01 04
+ * Michael Elizabeth Chastain <mec@shout.net>
+ * - Call clear_globalflags when writing out update_mainmenu.
+ *   This fixes the missing global/vfix lines for ARCH=alpha on 2.2.0-pre4.
+ *
+ * 8 January 1999, Michael Elizabeth Chastain <mec@shout.net>
+ * - Emit menus_per_column
+ *
+ * 14 January 1999, Michael Elizabeth Chastain <mec@shout.net>
+ * - Steam-clean this file.  I tested this by generating kconfig.tk for every
+ *   architecture and comparing it character-for-character against the output
+ *   of the old tkparse.
+ * - Fix flattening of nested menus.  The old code simply assigned items to
+ *   the most recent token_mainmenu_option, without paying attention to scope.
+ *   For example: "menu-1 bool-a menu-2 bool-b endmenu bool-c bool-d endmenu".
+ *   The old code would put bool-a in menu-1, bool-b in menu-2, and bool-c
+ *   and bool-d in *menu-2*.  This hosed the nested submenus in
+ *   drives/net/Config.in and other places.
+ * - Fix menu line wraparound at 128 menus (some fool used a 'char' for
+ *   a counter).
+ *
+ * 23 January 1999, Michael Elizabeth Chastain <mec@shout.net>
+ * - Remove bug-compatible code.
+ *
+ * 07 July 1999, Andrzej M. Krzysztofowicz <ankry@mif.pg.gda.pl>
+ * Some bugfixes, including
+ * - disabling "m" options when CONFIG_MODULES is set to "n" as well as "y"
+ *   option in dep_tristate when dependency is set to "m",
+ * - deactivating choices which should not be available,
+ * - basic validation for int and hex introduced if the entered one is not 
+ *   valid,
+ * - updates of all opened menus instead of the active only. I was afraid
+ *   that it would slow down updates, but I don't even see any speed difference
+ *   on my machine. If it slows you can still work with only a single menu
+ *   opened,
+ * - fixed error when focussing non-existent window (especially Help windows),
+ * Higher level submenus implemented.

+ * tkparse.c
+ *
+ * Eric Youngdale was the original author of xconfig.
+ * Michael Elizabeth Chastain (mec@shout.net) is the current maintainer.
+ *
+ * Parse a config.in file and translate it to a wish script.
+ * This task has three parts:
+ *
+ *   tkparse.c	tokenize the input
+ *   tkcond.c   transform 'if ...' statements
+ *   tkgen.c    generate output
+ *
+ * Change History
+ *
+ * 7 January 1999, Michael Elizabeth Chastain, <mec@shout.net>
+ * - Teach dep_tristate about a few literals, such as:
+ *     dep_tristate 'foo' CONFIG_FOO m
+ *   Also have it print an error message and exit on some parse failures.
+ *
+ * 14 January 1999, Michael Elizabeth Chastain, <mec@shout.net>
+ * - Don't fclose stdin.  Thanks to Tony Hoyle for nailing this one.
+ *
+ * 14 January 1999, Michael Elizabeth Chastain, <mec@shout.net>
+ * - Steam-clean this file.  I tested this by generating kconfig.tk for
+ *   every architecture and comparing it character-for-character against
+ *   the output of the old tkparse.
+ *
+ * 23 January 1999, Michael Elizabeth Chastain, <mec@shout.net>
+ * - Remove bug-compatible code.
+ *
+ * 07 July 1999, Andrzej M. Krzysztofowicz, <ankry@mif.pg.gda.pl>
+ * - Submenus implemented,
+ * - plenty of option updating/displaying fixes,
+ * - dep_bool, define_hex, define_int, define_string, define_tristate and
+ *   undef implemented,
+ * - dep_tristate fixed to support multiple dependencies,
+ * - handling of variables with an empty value implemented,
+ * - value checking for int and hex fields,
+ * - more checking during condition parsing; choice variables are treated as
+ *   all others now,
+ *
+ * TO DO:
+ * - xconfig is at the end of its life cycle.  Contact <mec@shout.net> if
+ *   you are interested in working on the replacement.
