/* yppRAW.c
 * Version 0.01
 * This is a File input and output filter for the
 * GIMP. It loads images in the RAW format used by
 * Three Rings Design's "Yo ho ho! Puzzle Pirates!"
 *
 * Some Parts that deal with the interaction with
 * the GIMP are taken from the BMP plugin by
 * Alexander Schulz, who in turn borrowed from the
 * GIF plugin by Peter Mattis & SPencer Kimball,
 * and from the PCX plugin by Francisco Bustamante
 *
 * I didn't look at their stuff, so I don't know
 * if I'm using it or not.
