- 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. */
