 3# This is a demo program that shows how to
 4# create radio buttons and how to get other widgets to
 5# share the information in a radio button.
 6#
 7# There are other ways of doing this too, but
 8# the "variable" option of radiobuttons seems to be the easiest.
 9#
10# note how each button has a value it sets the variable to as it gets hit.
