- * HOG support routines for PhysicsFS.
- *
- * This driver handles Descent I/II HOG archives.
- *
- * The format is very simple:
- *
- * The file always starts with the 3-byte signature "DHF" (Descent
- * HOG file). After that the files of a HOG are just attached after
- * another, divided by a 17 bytes header, which specifies the name
- * and length (in bytes) of the forthcoming file! So you just read
- * the header with its information of how big the following file is,
- * and then skip exact that number of bytes to get to the next file
- * in that HOG.
- *
- * char sig[3] = {'D', 'H', 'F'}; // "DHF"=Descent HOG File
- *
- * struct {
- * char file_name[13]; // Filename, padded to 13 bytes with 0s
- * int file_size; // filesize in bytes
- * char data[file_size]; // The file data
- * } FILE_STRUCT; // Repeated until the end of the file.
- *
- * (That info is from http://www.descent2.com/ddn/specs/hog/)
- *
- * Please see the file LICENSE.txt in the source's root directory.
- *
- * This file written by Bradley Bell.
- * Based on grp.c by Ryan C. Gordon.
