36 | REQUIRE_ORDER means don't recognize them as options; stop option | |

38 | specifies should happen. | |
39 | ||
40 | PERMUTE means permute the contents of ARGV as we scan, so that | |
41 | eventually all the non-options are at the end. This allows options | |
42 | to be given in any order, even with programs that were not written | |
43 | to expect this. | |
44 | ||
45 | RETURN_IN_ORDER is an option available to programs that were | |
46 | written to expect options and other ARGV-elements in any order | |
47 | and that care about the ordering of the two. We describe each | |
48 | non-option ARGV-element as if it were the argument of an option | |
49 | with character code 1. | |
50 | ||
51 | The special argument '--' forces an end of option-scanning regardless | |
52 | of the value of 'ordering'. In the case of RETURN_IN_ORDER, only | |
53 | '--' can cause 'getopt' to return -1 with 'optind' != ARGC. */ | |
