* 8 January 1999, Michael Elizabeth Chastain <mec@shout.net>
* - Emit menus_per_column
*
- * 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.
- *
- * 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.
- * - clean up +/- 16 confusion for enabling/disabling variables; causes
- * (theoretical, at the moment) problems with dependencies.
- *
+ * 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).
