# This is a demo program that shows how to 
# create radio buttons and how to get other widgets to 
# share the information in a radio button. 
# 
# There are other ways of doing this too, but 
# the "variable" option of radiobuttons seems to be the easiest.
#
# note how each button has a value it sets the variable to as it gets hit.
