This file describes Listbox.patch which alters the standard listbox
widget to allow disjoint selections.

Listbox.patch is a patch to the original Tk 3.2 sources.  The patch
alters the following files:

tkListbox.c
library/tk.tcl
library/listbox.tcl
doc/listbox.n

After applying the patches you will need to do a make install.

To get an understanding of the bindings read the man page and look
at the class bindings in tk.tcl.  The bindings are somewhat arbitrary,
though I did try to make them sensible.

Your existing programs should not break (I hope :-).  If they do, please
let me know.  Remember, you can undo the patches with patch -R.

Please send me mail with any suggestions and problems.
