50.Sh DESCRIPTION
51This program lets you play backgammon against the computer
52or against a "friend".
53All commands are only one letter, so you don't need to type a carriage return,
54except at the end of a move.
55The program is mostly self-explanatory,
56so that a question mark (?) will usually get some help.
57If you answer `y' when the program asks if you want the rules,
58you will get text explaining the rules of the game, some hints on strategy,
59instructions on how to use the program,
60and a tutorial consisting of a practice game against the computer.
61A description of how to use the program can be
62obtained by answering `y' when it asks if you want instructions.

104so the board does not need to be reprinted,
105unless the screen suffers some horrendous malady.
106Also, any `p' option will be ignored.
107(The `t' option is not necessary unless the terminal type does not match
108the entry in the
109.Pa /usr/share/misc/termcap
110data base.)
