Obviously this README is totally incomplete, and will probably remain so for
quite a while, so I'll just try to list a few important notes.

Yes, the code does currently do something. No, it's not ready for a release.
No, it is not vaporware. I hope to at least complete the single portion of
the game before making an official release.
If you are really itching to try this out, either install the Gold Ed. in
windows/vmware (read below to find out why), or download the AvP Alien demo.
If you are wanting to run the Alien demo (the installer is an .exe but you
can just use unzip to extract the files from the .exe), add -DALIEN_DEMO to
CFLAGS (the one that's uncommented). Rename all game files lowercase.

Support for the demo is not quite complete (some sounds are missing and some
text is incorrect/missing).
The source code that was released only works with Aliens vs Predator Gold.
In the future I'd like this port to support Gold, Regular and the three
demos. Plus, I am told that the Regular edition does seem to work by

Thanks go out to Chuck Mason for testing and the OpenAL code, Dan Olson for
trying the code out with the Regular version, and Ryan C. Gordon for hosting
this project.
