This is an old revision of the document!
It's located in tools/rtpack.
It's a MSVC project that requires Clanlib 1.X and the PowerVR libraries (for .pvrtc texture creation) to compiles.
The PowerVR stuff should (unless you want to mess with paths) be located in shared/win/powerVR. (the dirs OGLES and Windows and the file sdkver.h should be copied there)
Note: Unless you really need to tweak something you never really need to compile this as the .exe version is included.
Want to help by compiling an OSX version? Add it here!
