! 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.)
