MListbox-patch patches Tk 3.6 to enable non-contiguous selections in a
listbox.  MListbox-patch is a patch to the original Tk 3.6 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.

Non-contiguous selection ability is off by default.  In order to enable this
enhancement you need to do

	<widget> configure -multipleselections 1

or create the widget with

	listbox <widget> -multipleselections 1

A value of 0 selects the traditional behaviour, anything else selects the
enhanced behaviour.

The listbox test fails a number of times bue to slightly different semantics
in selection manipulation.  Your existing programs *should* not break.  If
they do, please let me know.  Remember, you can undo the patches with patch -R.

Please send me mail with any suggestions or problems.

Thanks to Heiko Schroeder <heiko@pool.informatik.rwth-aachen.de> for the
-multipleselections toggle and bringing things up to 3.6!
