     NAME
          xvier - a X11 board game.

     SYNOPSIS
          xvier [ -display displayname ] [ -geometry geometry ] [ -fn fontpattern
          ] [ -iconic ] [ -rows rows ] [ -columns columns ] [ -prog programpath ]
          [ -level levelnumber ]

     DESCRIPTION
          Xvier is a board game where you and the computer alternately throw
          stones into free columns. The stones pile up in the columns, and the
          goal is to get four stones in a row, in a column or diagonally. You
          can choose various board sizes and levels of difficulty.  During the
          game you click with the mouse onto the column where you want to put
          your stone. Another possibility is a lower case letter in the range
          'a' to 'm' (maximally) where 'a' is the left column. If you want to
          change the level of difficulty, you must use the keyboard.  Simply
          type the number of the desired level. These levels correspond to the
          search depth of the game program. The meaning of the command line
          options and buttons is given below.  While the game program computes a
          move, everything besides Change and Quit is blocked.

     OPTIONS
          -display displayname
               The X11 screen you want to use.

          -fn fontpattern
               A pattern describing the fonts which are used for the buttons and
               messages.  Xvier chooses the biggest font that fits into the
               window. Therefore the pattern should describe different sizes of
               one font. The default is *-Helvetica-Medium-R-Normal-*.

               Start in iconic state.

               The number of rows of the board. The possible range is 4 to 13.
               The default is 6.

          -columns columns
               The number of columns of the board. The possible range is 4 to
               13. The default is 7.

          -prog programpath
               The path of the game program.
