 * Module: stackres
 * Owner: knox
 * stdout: text description
 * args:
 *   name         (name of the input res file)
 *
 * Description:
 *    This program reads an RES file, executes it and produces a
 *    text description file.  The name of the RES file is the
 *    the first argument of the command line.  The text description
 *    written to the standard output describes the results left
 *    on the stack after the image has been 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.
