Prepared for public release: 03/21/2003 - Charlie Wiederhold, 3D Realms

EDuke enhancements integrated: 04/13/2003 - Matt Saettler

Note: EDuke source was in transition.  Changes are in-progress in the
source as it is released.

This file is a combination of code from the following sources:
- EDuke 2 by Matt Saettler
- JFDuke by Jonathon Fowler (jf@jonof.id.au),
- DukeGDX and RedneckGDX by Alexander Makarov-[M210] (m210-2007@mail.ru)
- Redneck Rampage reconstructed source by Nuke.YKT

Note:
 Most of this code follows DukeGDX and RedneckGDX because for Java it had
 to undo all the macro hackery that make the Duke source extremely hard to read.
 The other code bases were mainly used to add missing feature support (e.g. WW2GI)
 and verify correctness.
