5// Because I (Nikolaus Gebhardt) did some changes to Murphy McCauley's loader,
6// I'm writing this down here:
7// - Replaced all dependencies to STL and stdio with irr:: methods/constructs
8// - Disabled logging define
9// - Changed some minor things (Don't remember what exactly.)
10// Thanks a lot to Murphy McCauley for writing this loader.
