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.
