Programming
From FreeOrionWiki
FreeOrion is being made with C++, OpenGL and GiGi. The programming lead is Tzlaine, who unfortunately is "missing in action" at the moment. Until he returns, Yoghurt has taken the role of deputy lead programmer.
If you want to contribute, please speak to Yoghurt and take the time to be familiar with the source code. Programming Work contains a list of things needed to be completed.
Here you can find information on procedures, code standards, etc:
