 /* Describe how to deal with options that follow non-option ARGV-elements.

    If the caller did not specify anything,
    the default is REQUIRE_ORDER if the environment variable
    POSIXLY_CORRECT is defined, PERMUTE otherwise.

    REQUIRE_ORDER means don't recognize them as options;
    stop option processing when the first non-option is seen.
    This is what Unix does.
    This mode of operation is selected by either setting the environment
    variable POSIXLY_CORRECT, or using `+' as the first character
    of the list of option characters.

    PERMUTE is the default.  We permute the contents of ARGV as we
    scan, so that eventually all the non-options are at the end.
    This allows options to be given in any order, even with programs
    that were not written to expect this.

    RETURN_IN_ORDER is an option available to programs that were
    written to expect options and other ARGV-elements in any order
    and that care about the ordering of the two.  We describe each
    non-option ARGV-element as if it were the argument of an option
    with character code 1.  Using `-' as the first character of the
    list of option characters selects this mode of operation.

    The special argument `--' forces an end of option-scanning regardless
    of the value of `ordering'.  In the case of RETURN_IN_ORDER, only
    `--' can cause `getopt' to return -1 with `optind' != ARGC.  */
