00040 // How does this work?
00041 // Remember that before the compiler starts to process a source file, it runs
00042 // a neat tool called a preprocessor on it. What this preprocessor does in
00043 // this case is replace all the instances of *alloc/free with the expanded
00044 // macros - this way we cleverly replace all the calls to the standard C
00045 // memory (de)allocation functions. The same is done for new/delete
00046 //
00047 // Of course, we have the drawback that we can't name a member function of
00048 // a class *alloc or free and we can't overload the new/delete operators without
00049 // first undefining these macros - ah, a C++ preprocessor with RE replacement,
00050 // that would be a dream come true :)
