For unrecognized options, or options missing arguments, * `custom_optopt' is set to the option letter, and '?' is returned. * * The OPTS string is a list of characters which are recognized option letters, * optionally followed by colons, specifying that that letter takes an * argument, to be placed in `custom_optarg'. * * If a letter in OPTS is followed by two colons, its argument is optional. * This behavior is specific to the GNU `getopt'. * * The argument `--' causes premature termination of argument scanning, * explicitly telling `getopt' that there are no more options. If OPTS begins * with `--', then non-option arguments are treated as arguments to the option * '\0'.
