DEHSUPP is a lump introduced by ZDoom that is used to add things to the list of actors and weapons that can be modified by DeHackEd. By compiling a DEHSUPP lump using the associated utility and inserting it into a WAD file, DeHackEd patches can reference things from Heretic, Hexen, and even Strife. It should be noted that DEHSUPP does not do anything by itself, and must be used in conjunction with either an internal or external DeHackEd patch that takes advantage of the new references.
