.Sh DESCRIPTION
|
|
.Nm
|
|
is a two player game were the object is to get 5 in a row horizontally,
|
|
vertically or diagonally on a 19 by 19 grid.
|
|
By convention, black always moves first.
|
|
With no arguments,
|
|
.Nm
|
|
will display a playing board and prompt for moves from the user.
|
|
Valid moves are a letter for the column and a number for the row of an empty
|
|
board location.
|
|
Entering ``quit" or ``resign" will end the game.
|
|
You can save the current state of the game by entering ``save" and
|
|
supplying a file name when prompted.
|
|
The optional file
|
|
.Ar inputfile
|
|
can be used to restore a saved game.
|
|
.Pp
|
|
The options are:
|
|
.Bl -tag -width Ds
|
|
.It Fl b
|
|
This option sets background mode.
|
|
Input moves are read from standard input,
|
|
the computer picks a move, and prints it to standard output.
|
|
The first input line should be either ``black" or ``white" to specify whether
|
|
.Nm
|
|
has the first move or not respectively.
|
|
This option was intended for game tournaments where a referee program handles
|
|
the board display and pits one program against another.
|
|
.It Fl c
|
|
Computer versus computer.
|
|
.Nm
|
|
will play a game against itself.
|
|
This is mostly used for testing.
|
|
.It Fl d
|
|
Print debugging information.
|
|
Repeating this option more than once yields more detailed information.
|
|
.It Fl D Ar debugfile
|
|
Print the debug information to
|
|
.Ar debugfile
|
|
instead of to the standard output.
|
|
.It Fl u
|
|
User versus user.
|
|
This is mostly used for testing.
