- * GRP support routines for PhysicsFS.
- *
- * This driver handles BUILD engine archives ("groupfiles"). This format
- *  (but not this driver) was put together by Ken Silverman.
- *
- * The format is simple enough. In Ken's words:
- *
- *    What's the .GRP file format?
- *
- *     The ".grp" file format is just a collection of a lot of files stored
- *     into 1 big one. I tried to make the format as simple as possible: The
- *     first 12 bytes contains my name, "KenSilverman". The next 4 bytes is
- *     the number of files that were compacted into the group file. Then for
- *     each file, there is a 16 byte structure, where the first 12 bytes are
- *     the filename, and the last 4 bytes are the file's size. The rest of
- *     the group file is just the raw data packed one after the other in the
- *     same order as the list of files.
- *
- * (That info is from http://www.advsys.net/ken/build.htm ...)
- *
- * Please see the file LICENSE.txt in the source's root directory.
- *
- *  This file written by Ryan C. Gordon.
