Pioneer is a space adventure game set in the Milky Way galaxy at the turn of
the 31st century.

The game is open-ended, and you are free to explore the millions of star
systems in the game. You can land on planets, slingshot past gas giants, and
burn yourself to a crisp flying between binary star systems. You can try your
hand at piracy, make your fortune trading between systems, or do missions for
the various factions fighting for power, freedom or self-determination.

OpenGL core profile version 3.1 or newer is a runtime dependency, to determine
what version of OpenGL is installed use:

  glxinfo | grep "core profile version"

Pioneer's game data is by default installed in /usr/share/games and will take
up around 400M of hard drive space. This SlackBuild allows choosing an alternate
game data directory to install in, to do this use:

  DATADIR=/path/to/data ./pioneer.SlackBuild

For example to install the data to /opt/pioneer use:

  DATADIR=/opt ./pioneer.SlackBuild

To build with debugging support use:

  DEBUG="yes" ./pioneer.SlackBuild
