** Much of this file is fudging code to compensate for the fact that most of
** what could be changed with Dehacked is no longer in the same state it was
** in as of Doom 1.9. There is a lump in zdoom.wad (DEHSUPP) that stores most
** of the lookup tables used so that they need not be loaded all the time.
** Also, their total size is less in the lump than when they were part of the
** executable, so it saves space on disk as well as in memory.
