"""One of the bad things about Tk/Tkinter is that it does not pick up
the current color and font scheme from the prevailing CDE/KDE/GNOME/Windows 
window manager scheme.

One of the good things about Tk/Tkinter is that it is not tied to one
particular widget set so it could pick up the current color and font scheme 
from the prevailing CDE/KDE/GNOME/Windows window manager scheme.

The WmDefault package is for making Tk/Tkinter applications use the 
prevailing CDE/KDE/GNOME/Windows scheme. It tries to find the files
and/or settings that the current window manager is using, and then
sets the Tk options database accordingly.

Download the latest version of wm_default from http://tix.sourceforge.net
either as a part of the standard Tix distribution, or as a part of the
Tix Applications: http://tix.sourceforge.net/Tide. wm_default does not
require Tix, but is Tix enabled.
