27 * This encapsulates the user's command-line request to replace existing,
28 * incorrect pathnames to models and textures from a file with correct
29 * pathnames. It corresponds to a sequence of -pr command-line options, as
30 * well as the -pp option.
31 *
32 * This can also go the next step, which is to convert a known file into a
33 * suitable form for storing in a model file. In this capacity, it
34 * corresponds to the -ps and -pd options.
