+ 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. */
