/* 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.
*
* TO DO:
* - clean up - there are useless ifdef's everywhere.
* - better comments throughout - C code generating tcl is really cryptic.
* - eliminate silly "update idletasks" hack to improve display speed and
* reduce flicker. But how?
* - make canvas contents resize with the window (good luck).
* - some way to make submenus inside of submenus (ie. Main->Networking->IP)
* (perhaps a button where the description would be)
* - make the main menu use the same tcl code as the submenus.
* - make choice and int/hex input types line up vertically with
* bool/tristate.
* - general speedups - how? The canvas seems to slow it down a lot.
* - choice buttons should default to the first menu option, rather than a
* blank. Also look up the right variable when the help button
* is pressed.
* - clean up +/- 16 confusion for enabling/disabling variables; causes
* (theoretical, at the moment) problems with dependencies.
