  50 .Sh DESCRIPTION
  51 .Nm
  52 is a two player game were the object is to get 5 in a row horizontally,
  53 vertically or diagonally on a 19 by 19 grid. By convention, black always
  54 moves first.
  55 With no arguments,
  56 .Nm
  57 will display a playing board and prompt for moves from the user.
  58 Valid moves are a letter for the column and a number for the row of an empty
  59 board location. Entering ``quit" or ``resign" will end the game.
  60 You can save the current state of the game by entering ``save" and
  61 supplying a file name when prompted.
  62 The optional file
  63 .Ar inputfile
  64 can be used to restore a saved game.
  65 .Pp
  66 The options are:
  67 .Bl -tag -width Ds
  68 .It Fl b
  69 This option sets background mode. Input moves are read from standard input,
  70 the computer picks a move, and prints it to standard output. The first
  71 input line should be either ``black" or ``white" to specify whether
  72 .Nm
  73 has the first move or not respectively. This
  74 option was intended for game tournaments where a referee program handles
  75 the board display and pits one program against another.
  76 .It Fl c
  77 Computer verses computer.
  78 .Nm
  79 will play a game against itself. This is mostly used for testing.
  80 .It Fl d
  81 Print debugging information. Repeating this option more than
  82 once yields more detailed information.
  83 .It Fl D Ar debugfile
  84 Print the debug information to
  85 .Ar debugfile
  86 instead of to the standard output.
  87 .It Fl u
  88 User verses user. This is mostly used for testing.
