/* Generate tk script based upon config.in

 *
3
 * Version 1.0
4
 * Eric Youngdale
5
 * 10/95
6
 *
7
 * 1996 01 04
8
 * Avery Pennarun - Aesthetic improvements.
9
 *
10
 * 1996 01 24
11
 * Avery Pennarun - Bugfixes and more aesthetics.
12
 *
13
 * 1996 03 08
14
 * Avery Pennarun - The int and hex config.in commands work right.
15
 *                - Choice buttons are more user-friendly.
16
 *                - Disabling a text entry line greys it out properly.
17
 *                - dep_tristate now works like in Configure. (not pretty)
18
 *                - No warnings in gcc -Wall. (Fixed some "interesting" bugs.)
19
 *                - Faster/prettier "Help" lookups.
20
 *
21
 * 1996 03 15
22
 * Avery Pennarun - Added new sed script from Axel Boldt to make help even
23
 *                  faster. (Actually awk is downright slow on some machines.)
24
 *                - Fixed a bug I introduced into Choice dependencies.  Thanks
25
 *                  to Robert Krawitz for pointing this out.
26
 *
27
 * 1996 03 16
28
 * Avery Pennarun - basic "do_make" support added to let sound config work.
29
 *
30
 * 1996 03 25
31
 *     Axel Boldt - Help now works on "choice" buttons.
32
 *
33
 * 1996 04 06
34
 * Avery Pennarun - Improved sound config stuff. (I think it actually works
35
 *                  now!)
36
 *                - Window-resize-limits don't use ugly /usr/lib/tk4.0 hack.
37
 *                - int/hex work with tk3 again. (The "cget" error.)
38
 *                - Next/Prev buttons switch between menus.  I can't take
39
 *                  much credit for this; the code was already there, but
40
 *                  ifdef'd out for some reason.  It flickers a lot, but
41
 *                  I suspect there's no "easy" fix for that.
42
 *                - Labels no longer highlight as you move the mouse over
43
 *                  them (although you can still press them... oh well.)
44
 *                - Got rid of the last of the literal color settings, to
45
 *                  help out people with mono X-Windows systems.
46
 *                  (Apparently there still are some out there!)
47
 *                - Tabstops seem sensible now.
48
 *
49
 * 1996 04 14
50
 * Avery Pennarun - Reduced flicker when creating windows, even with "update
51
 *                  idletasks" hack.
52
 *
53
 * 1997 12 08
54
 * Michael Chastain - Remove sound driver special cases.
55
 *
56
 * 1997 11 15
57
 * Michael Chastain - For choice buttons, write values for all options,
58
 *                    not just the single chosen one.  This is compatible
59
 *                    with 'make config' and 'make oldconfig', and is
60
 *                    needed so smart-config dependencies work if the
61
 *                    user switches from one configuration method to
62
 *                    another.
63
 *
64
 * 1998 03 09
65
 * Axel Boldt - Smaller layout of main menu - it's still too big for 800x600.
66
 *            - Display help in text window to allow for cut and paste.
67
 *            - Allow for empty lines in help texts.
68
 *            - update_define should not set all variables unconditionally to
69
 *              0: they may have been set to 1 elsewhere. CONFIG_NETLINK is
70
 *              an example.
71
 *
72
 * 1999 01 04
73
 * Michael Elizabeth Chastain <mec@shout.net>
74
 * - Call clear_globalflags when writing out update_mainmenu.
75
 *   This fixes the missing global/vfix lines for ARCH=alpha on 2.2.0-pre4.
76
 *
77
 * 8 January 1999, Michael Elizabeth Chastain <mec@shout.net>
78
 * - Emit menus_per_column
79
 *
80
 * 14 January 1999, Michael Elizabeth Chastain <mec@shout.net>
81
 * - Steam-clean this file.  I tested this by generating kconfig.tk for every
82
 *   architecture and comparing it character-for-character against the output
83
 *   of the old tkparse.
84
 * - Fix flattening of nested menus.  The old code simply assigned items to
85
 *   the most recent token_mainmenu_option, without paying attention to scope.
86
 *   For example: "menu-1 bool-a menu-2 bool-b endmenu bool-c bool-d endmenu".
87
 *   The old code would put bool-a in menu-1, bool-b in menu-2, and bool-c
88
 *   and bool-d in *menu-2*.  This hosed the nested submenus in
89
 *   drives/net/Config.in and other places.
90
 * - Fix menu line wraparound at 128 menus (some fool used a 'char' for
91
 *   a counter).
92
 *
93
 * 23 January 1999, Michael Elizabeth Chastain <mec@shout.net>
94
 * - Remove bug-compatible code.
95
 *
96
 * 07 July 1999, Andrzej M. Krzysztofowicz <ankry@mif.pg.gda.pl>
97
 * Some bugfixes, including
98
 * - disabling "m" options when CONFIG_MODULES is set to "n" as well as "y"
99
 *   option in dep_tristate when dependency is set to "m",
100
 * - deactivating choices which should not be available,
101
 * - basic validation for int and hex introduced if the entered one is not
102
 *   valid,
103
 * - updates of all opened menus instead of the active only. I was afraid
104
 *   that it would slow down updates, but I don't even see any speed difference
105
 *   on my machine. If it slows you can still work with only a single menu
106
 *   opened,
107
 * - fixed error when focussing non-existent window (especially Help windows),
108
 * Higher level submenus implemented.
