of stencil shadows via the "depth fail" method, a functionality commonly known as "Carmack's Reverse".

If you have obtained this source code several weeks after the time of release,
it is likely that you can find modified and improved versions of the engine in

conditions:
(1) If any part of the source code for this software is distributed, then this
README file must be included, with this copyright and no-warranty notice
unaltered; and any additions, deletions, or changes to the original files

NOTE: unfortunately the README that came with our copy of the library has
been lost, so the one from release 6b is included instead. There are a few
'glue type' modifications to the library to make it easier to use from
the engine, but otherwise the dependency can be easily cleaned up to a
better release of the library.
