# 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.
