7 # 8 January 1999, Michael Elizabeth Chastain, <mec@shout.net>
8 # - Remove unused do_cmd function (part of the 2.0 sound support).
9 # - Arrange buttons in three columns for better screen fitting.
10 # - Add CONSTANT_Y, CONSTANT_M, CONSTANT_N for commands like:
11 # dep_tristate 'foo' CONFIG_FOO m
12 #
13 # 23 January 1999, Michael Elizabeth Chastain, <mec@shout.net>
14 # - Shut vfix the hell up.
15 #
16 # 24 January 1999, Michael Elizabeth Chastain, <mec@shout.net>
17 # - Improve the exit message (Jeff Ronne).

20 # This is a handy replacement for ".widget cget" that requires neither tk4
21 # nor additional source code uglification.
