   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.
