FreeOrion is a free, open source, 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.

Note: for mitigating a hard to track segfault bug in freeoriond, clang is
used to compile freeorion instead of gcc
