// Because I (Nikolaus Gebhardt) did some changes to Murphy McCauley's loader,

// - Replaced all dependencies to STL and stdio with irr:: methods/constructs
// - Disabled logging define
// - Changed some minor things (Don't remember what exactly.)
// Thanks a lot to Murphy McCauley for writing this loader.
