-      <description>Reversi can be played with two different initial positions (and their variants). If 
“true”, the game will randomly start with one or the other position; if “false”, only the most common initial 
position is used. You can force the game to use the alternative position by using the “--alternative-start” 
argument on the command-line; also, if either “--usual-start” or “--random-start” is given instead on the 
command-line, this flag will be ignored.</description>
