# Animated Towers of Hanoi using Tk with optional bitmap file in
# background.
#
# Usage: tkhanoi [n [bitmapfile]]
#
# n is the number of pieces to animate; default is 4, maximum 15.
#
# The bitmap file can be any X11 bitmap file (look in
# /usr/include/X11/bitmaps for samples); it is displayed as the
# background of the animation.  Default is no bitmap.

# This uses Steen Lumholt's Tk interface
