35  If the caller did not specify anything,
36  the default is REQUIRE_ORDER if the environment variable
37  POSIXLY_CORRECT is defined, PERMUTE otherwise.
38 
39  REQUIRE_ORDER means don't recognize them as options;
40  stop option processing when the first non-option is seen.
41  This is what Unix does.
42  This mode of operation is selected by either setting the environment
43  variable POSIXLY_CORRECT, or using '+' as the first character
44  of the list of option characters, or by calling getopt.
45 
46  PERMUTE is the default. We permute the contents of ARGV as we
47  scan, so that eventually all the non-options are at the end.
48  This allows options to be given in any order, even with programs
49  that were not written to expect this.
50 
51  RETURN_IN_ORDER is an option available to programs that were
52  written to expect options and other ARGV-elements in any order
53  and that care about the ordering of the two. We describe each
54  non-option ARGV-element as if it were the argument of an option
55  with character code 1. Using '-' as the first character of the
56  list of option characters selects this mode of operation.
57 
58  The special argument '--' forces an end of option-scanning regardless
59  of the value of 'ordering'. In the case of RETURN_IN_ORDER, only
60  '--' can cause 'getopt' to return -1 with 'optind' != ARGC. */
