/* 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. */
