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,

              create balance  problems.  Very  high  numbers  of  AIs  may  cause  lag  problems,
