- * 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.)
- *
- * Date: 05.Nov.90
- *
- * $Id: hanoi.c,v 1.23 2002/03/24 00:40:01 tom Exp $
