// READ THIS!
// To compile make sure to include DDRAW.LIB, DSOUND.LIB,
// DINPUT.LIB, DINPUT8.LIB, WINMM.LIB in the project link list, and of course 
// the C++ source modules T3DLIB1,4,5,6.CPP and the headers T3DLIB1,4,5,6.H
// be in the working directory of the compiler
// compile as a win32 CONSOLE APPLICATION not a WIN32 .EXE!!!
