-# This script generates a demo application containing only a "square"
-# widget. It's only usable in the "tktest" application or if Tk has
-# been compiled with tkSquare.c. This demo arranges the following
-# bindings for the widget:
-#
-# Button-1 press/drag: moves square to mouse
-# "a": toggle size animation on/off
-#
-# RCS: @(#) $Id$
