/* 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.
