 * Module: restotext
 * Owner: knox
 * stdout: text description
 * args:
 *   name         (name of the input res file)
 * 
 * Description:
 *    This program reads an RES file and writes out a line-by-line
 *    text description of the file.  The name of the RES file is the
 *    the first argument of the command line.  A text description
 *    of the image is written to the standard output.  The commands
 *    in the RES file are translated, but the RES file is not executed.
 * 
 *    The image raster will be read from the file "name.res",
 *    where name is read from the command line.  The ".res"
 *    extension will not be added if it is already present in the
 *    name.
