 *	Name: Towers of Hanoi.
 *
 *	Desc:
 *		This is a playable copy of towers of hanoi.
 *		Its sole purpose is to demonstrate my Amiga Curses package.
 *		This program should compile on any system that has Curses.
 *		'hanoi'		will give a manual game with 7 playing pieces.
 *		'hanoi n'	will give a manual game with n playing pieces.
 *		'hanoi n a' will give an auto solved game with n playing pieces.
 *
 *	Author: Simon J Raybould	(sie@fulcrum.bt.co.uk).
 * 	(This version has been slightly modified by the ncurses maintainers.)
