        !            17: .sh DESCRIPTION
        !            18: This program lets you play backgammon against the computer
        !            19: or against a "friend".
        !            20: All commands only are one letter,
        !            21: so you don't need to type a carriage return,
        !            22: except at the end of a move.
        !            23: The program is mostly self documenting,
        !            24: so that a question mark (?) will usually get some help.
        !            25: If you answer `y' when the program asks if you want the rules,
        !            26: you will get text explaining the rules of the game,
        !            27: some hints on strategy,
        !            28: instruction on how to use the program,
        !            29: and a tutorial consisting of a practice game against the computer.
        !            30: A description of how to use the program can be
        !            31: obtained by answering `y' when it asks if you want instructions.
