- /* 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.
