    00044 // How does this work?
    00045 // Remember that before the compiler starts to process a source file, it runs
    00046 // a neat tool called a preprocessor on it. What this preprocessor does in
    00047 // this case is replace all the instances of *alloc/free with the expanded
    00048 // macros - this way we cleverly replace all the calls to the standard C
    00049 // memory (de)allocation functions. The same is done for new/delete
    00050 //
    00051 // Of course, we have the drawback that we can't name a member function of
    00052 // a class *alloc or free and we can't overload the new/delete operators without
    00053 // first undefining these macros - ah, a C++ preprocessor with RE replacement,
    00054 // that would be a dream come true :)
