[PATCH] remove old config tools 

This deletes the old config tools and moves Michael's maintainer entry
for them to CREDITS and I added myself for KCONFIG instead.

#! /bin/sh
#
# 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).
#
# 7 October 2000, Ghozlane Toumi, <gtoumi@messel.emse.fr>
# added switches for "random" , "all yes" and "all modules"
#
#
# Make sure we're really running bash.
#
# I would really have preferred to write this script in a language with
# better string handling, but alas, bash is the only scripting language
# that I can be reasonable sure everybody has on their linux machine.

#
# This script is used to configure the linux kernel.
#
# It was inspired by a desire to not have to hit <enter> 9 million times
# or startup the X server just to change a single kernel parameter.
#
# This script attempts to parse the configuration files, which are
# scattered throughout the kernel source tree, and creates a temporary
# set of mini scripts which are in turn used to create nested menus and
# radiolists.
#
# It uses a very modified/mutilated version of the "dialog" utility
# written by Savio Lam (lam836@cs.cuhk.hk). Savio is not responsible
# for this script or the version of dialog used by this script.
# Please do not contact him with questions. The official version of
# dialog is available at sunsite.unc.edu or a sunsite mirror.
#
# Portions of this script were borrowed from the original Configure
# script.
#
# William Roadcap was the original author of Menuconfig.
# Michael Elizabeth Chastain (mec@shout.net) is the current maintainer.
#
# 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).
#
# 13 Dec 1998, Riley H Williams <rhw@memalpha.cx>
# When an error occurs, actually display the error message as well as
# our comments thereon.
#
# 31 Dec 1998, Michael Elizabeth Chastain (mec@shout.net)
# 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).

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.

/*
* tkcond.c
*
* Eric Youngdale was the original author of xconfig.
* Michael Elizabeth Chastain (mec@shout.net) is the current maintainer.
*
* This file takes the tokenized statement list and transforms 'if ...'
* statements. For each simple statement, I find all of the 'if' statements
* that enclose it, and attach the aggregate conditionals of those 'if'
* statements to the cond list of the simple statement.
*
* 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.
*
* 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
* you are interested in working on the replacement.

* 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.
