     backgammon - the game of backgammon

     backgammon [-bdnrw] [-s file]

     This program lets you play backgammon against the computer or against a
     `friend'.	All commands are only one letter, so you don't need to type a
     carriage return, except at the end of a move.  The program is mostly
     self-explanatory: a question mark (?) will usually get some help.	If you
     answer `y' when the program asks if you want the rules, you will get text
     explaining the rules of the game, some hints on strategy, instructions on
     how to use the program, and a tutorial consisting of a practice game
     against the computer.  A description of how to use the program can be
     obtained by answering `y' when it asks if you want instructions.

     The possible arguments for backgammon (most are unnecessary but some are
     very convenient) consist of:

     -b	     Two players, red and white (implies -n).

     -d	     Play without doubling.

     -n	     Don't ask for rules or instructions.

     -r	     Player is red (implies -n).

     -s file
	     Recover previously saved game from file.

     -w	     Player is white (implies -n).

     When the program prompts by typing only your color, type a space or
     carriage return to roll, or one of the following:

	   d	   to double
	   q	   to quit
	   r	   to redraw the board
	   s	   to save the game for later

     When the program prompts with 'Move:', type one of the following:

	   q	   to quit
	   r	   to redraw the board
	   s	   to save the game

     Or a move, which is a sequence of one of the following:

	   s-f	   move from s to f
	   s/r	   move one man on s the roll r separated by commas or spaces
		   and ending with a newline.  Available abbreviations are as

			 s-f1-f2     means s-f1,f1-f2
			 s/r1r2	     means s/r1,s/r2

     Use b for bar and h for home, or 0 or 25 as appropriate.

     The strategy is the ``pubeval'' algorithm of Gerry Tesauro, with minimal
     doubling logic added.
