+# 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.
