                     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

                     97: .PP
                     98: The scoring function takes into account the size of the screen.
                     99: A perfect function to do this equitably has not been devised.
