- * QPAK support routines for PhysicsFS.
- *
- *  This archiver handles the archive format utilized by Quake 1 and 2.
- *  Quake3-based games use the PkZip/Info-Zip format (which our zip.c
- *  archiver handles).
- *
- *  ========================================================================
- *
- *  This format info (in more detail) comes from:
- *     http://debian.fmi.uni-sofia.bg/~sergei/cgsr/docs/pak.txt
- *
- *  Quake PAK Format
- *
- *  Header
- *   (4 bytes)  signature = 'PACK'
- *   (4 bytes)  directory offset
- *   (4 bytes)  directory length

- *  Directory
- *   (56 bytes) file name
- *   (4 bytes)  file position
