-"""
+'''
-STABLE.
+Provides a RadioToolButton class, similar to a "push" button.
-"""
+A group of RadioToolButtons can be set, so that only one can be
+selected at a time. When a button is clicked, it depresses and
+is shaded darker.
+
+It is also possible to set a tooltip to be dispalyed when the
+user scrolls over it with their cursor as well as an accelerator
+keyboard shortcut.
+
+Example:
