.SH DESCRIPTION
|
|
This program lets you play backgammon against the computer
|
|
or against a "friend".
|
|
All commands only are one letter,
|
|
so you don't need to type a carriage return,
|
|
except at the end of a move.
|
|
The program is mostly self documenting,
|
|
so that 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,
|
|
instruction 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.
|
|
.PP
|
|
The possible arguments for backgammon
|
|
(most are unnecessary but some are very convenient)
|

If
|
|
.IR term
|
|
has capabilities for direct cursor movement (see
|
|
.IR termcap (5))
|
|
.IR backgammon
|
|
``fixes'' the board after each move,
|
|
so the board does not need to be reprinted,
|
|
unless the screen suffers some horrendous malady.
|
|
Also, any `-p' option will be ignored.
|
|
(The `-t' option is not necessary unless the terminal type does not match
|
|
the entry in the /etc/termcap data base.)
|
|
