.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)
|
|
consist of:
|
|
.Bl -tag -width indent
|
|
.It Fl n
|
|
don't ask for rules or instructions
|
|
.It Fl r
|
|
player is red (implies n)
|
|
.It Fl w
|
|
player is white (implies n)
|
|
.It Fl b
|
|
two players, red and white (implies n)
|
|
.It Fl pr
|
|
print the board before red's turn
|
|
.It Fl pw
|
|
print the board before white's turn
|
|
.It Fl pb
|
|
print the board before both player's turn
|
|
.It Fl t Ar term
|
|
terminal is type
|
|
.Ar term ,
|
|
uses /etc/termcap
|
|
.It Fl s Ar file
|
|
recover previously saved game from
|
|
.Ar file .
|
|
(This can also be done by executing the saved file,
|
|
i.e., typing its name in as a command)
|
|
.El
|
|
.Pp
|
|
.\"
|
|
.\" Arguments may be optionally preceded by a `-'.
|
|
.\" Several arguments may be concatenated together,
|
|
.\" but not after `s' or `t' arguments,
|
|
.\" since they can be followed by an arbitrary string.
|
|
Any unrecognized arguments are ignored.
|
|
An argument of a lone `-' gets a description of possible arguments.
|
|
.Pp
|
|
If
|
|
.Ar term
|
|
has capabilities for direct cursor movement (see
|
|
.Xr termcap 5 )
|
|
.Nm 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
|
|
.Pa /etc/termcap
|
|
data base.)
|
|
