        !            33: .SH DESCRIPTION
        !            34: Snake is a display-based game which must be played on a CRT terminal.
        !            35: The object of the game is to make as much money as possible without
        !            36: getting eaten by the snake.  The
        !            37: .B \-l
        !            38: and
        !            39: .B \-w
        !            40: options allow you to specify the length and width of the field.
        !            41: By default the entire screen (except for the last column) is used.
        !            42: .PP
        !            43: You are represented on the screen by an I.
        !            44: The snake is 6 squares long and is represented by S's.
        !            45: The money is $, and an exit is #.
        !            46: Your score is posted in the upper left hand corner.
        !            47: .PP
        !            48: You can move around using the same conventions as vi(1),
        !            49: the h, j, k, and l keys work, as do the arrow keys.
        !            50: Other possibilities include:
        !            51: .IP sefc
        !            52: These keys are like hjkl but form a directed pad around the d key.
        !            53: .IP HJKL
        !            54: These keys move you all the way in the indicated direction to the
        !            55: same row or column as the money.  This does
        !            56: .I not
        !            57: let you jump away from the snake, but rather saves you from having
        !            58: to type a key repeatedly.  The snake still gets all his turns.
        !            59: .IP SEFC
        !            60: Likewise for the upper case versions on the left.
        !            61: .IP ATPB
        !            62: These keys move you to the four edges of the screen.
        !            63: Their position on the keyboard is the mnemonic, e.g.
        !            64: P is at the far right of the keyboard.
        !            65: .IP x
        !            66: This lets you quit the game at any time.
        !            67: .IP p
        !            68: Points in a direction you might want to go.
        !            69: .IP w
        !            70: Space warp to get out of tight squeezes, at a price.
        !            71: .PP
        !            72: To earn money, move to the same square the money is on.
        !            73: A new $ will appear when you earn the current one.
        !            74: As you get richer, the snake gets hungrier.
        !            75: To leave the game, move to the exit (#).
        !            76: .PP
        !            77: A record is kept of the personal best score of each player.
        !            78: Scores are only counted if you leave at the exit,
        !            79: getting eaten by the snake is worth nothing.
        !            80: .PP
        !            81: As in pinball, matching the last digit of your score to the number
        !            82: which appears after the game is worth a bonus.
        !            83: .PP
        !            84: To see who wastes time playing snake, run

        !            99: A perfect function to do this equitably has not been devised.
