/* Describe how to deal with options that follow non-option ARGV-elements.
REQUIRE_ORDER means don't recognize them as options; stop option
processing when the first non-option is seen. This is what POSIX
specifies should happen.
PERMUTE means 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.
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. */
