# 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.
