21 This is a try to make the vm more generic, it is mainly based on the progs.h file.
22 For the license refer to progs.h.
24 Generic means, less as possible hard-coded links with the other parts of the engine.
25 This means no edict_engineprivate struct usage, etc.
26 The code uses void pointers instead.
