 *          enumdir_chmLib.c - CHM archive test driver                     *
 *                           -------------------                           *
 *                                                                         *
 *  author:     Jed Wing <[e-mail]>                         *
 *  notes:      This is a quick-and-dirty test driver for the chm lib      *
 *              routines.  The program takes as its input the paths to one *
 *              or more .chm files.  It attempts to open each .chm file in *
 *              turn, and display a listing of all of the files in the     *
 *              archive.                                                   *
 *                                                                         *
 *              It is not included as a particularly useful program, but   *
 *              rather as a sort of "simplest possible" example of how to  *
 *              use the enumerate portion of the API.                      *
