NAME
       FreeOrion - turn-based space empire and galactic conquest game
SYNOPSIS
       freeorion [OPTIONS]
DESCRIPTION
       FreeOrion  is a turn-based space empire and galactic conquest (4X) computer game being designed and built
       by the FreeOrion project. FreeOrion is inspired by the tradition of the Master of Orion games, but is not
       a clone or remake of that series or any other game.  The game is about  the  construction  of  a  living,
       breathing  universe  in  a grand campaign model. You can develop your own galactic empire and explore new
       star systems with your fleets as one of several unique human  or  alien  species.   Colonization  of  new
       worlds,  researching new technology, managing your resources and defending your planets against the AI or
       other human players on a galactic scale are your main objectives.
OPTIONS
       --GameSetup.ai-aggression
              The maximum aggression level for AI opponents. Most AIs will be at the level set, some may  be  at
              the next level below, all should greet you and state their level in the messages window during the
              first turn.  Default: BEGINNER
       --GameSetup.ai-players
              The  number  of  AI  opponents in the game. It is best to have at least one player for every 15-30
              systems in the game, playing with more or fewer AIs than this can create  balance  problems.  Very
              high numbers of AIs may cause lag problems, especially later in the game. | Default: 6

              Your empire's color. | Default: 9

       --GameSetup.native-frequency
              The frequency of natives in the galaxy. Some natives  can  be  technologically  advanced  and  may
