46.Sh DESCRIPTION
47This program lets you play backgammon against the computer
48or against a "friend".
49All commands are only one letter, so you don't need to type a carriage return,
50except at the end of a move.
51The program is mostly self-explanatory,
52so that a question mark (?) will usually get some help.
53If you answer `y' when the program asks if you want the rules,
54you will get text explaining the rules of the game, some hints on strategy,
55instructions on how to use the program,
56and a tutorial consisting of a practice game against the computer.
57A description of how to use the program can be
58obtained by answering `y' when it asks if you want instructions.

100so the board does not need to be reprinted,
101unless the screen suffers some horrendous malady.
102Also, any `p' option will be ignored.
103(The `t' option is not necessary unless the terminal type does not match
104the entry in the
105.Pa /usr/share/misc/termcap
106data base.)
