     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.
