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.

       -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.

       -level levelnumber
              The level of difficulty to start with. The possible range is 0 to 9.   The  default
              is 0.

BUTTONS

       The keyboard equivalents of the buttons are given in brackets.

       Quit ['q' or 'Q']   Finish the game.
