**
** Additionally, the input files may be listed in a separate list file (one
** resource name per line, optionally enclosed in double quotes). Pass the list
** via '--reslist <the-list-file>' option. Both lists, from the command line and
** the list file, are merged; duplicate file names skipped from processing.
** This option is useful to get around the command line length limitations
** under some OS, like Windows.
