- 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

-
- If an element of ARGV starts with '-', and is not exactly "-" or "--",
- then it is an option element. The characters of this element
- (aside from the initial '-') are option characters. If `getopt'
- is called repeatedly, it returns successively each of the option characters
- from each of the option elements.
-
- If `getopt' finds another option character, it returns that character,
- updating `optind' and `nextchar' so that the next call to `getopt' can
- resume the scan with the following option character or ARGV-element.
-
- If there are no more option characters, `getopt' returns `EOF'.
- Then `optind' is the index in ARGV of the first ARGV-element
- that is not an option. (The ARGV-elements have been permuted
- so that those that are not options now come last.)
-
- OPTSTRING is a string containing the legitimate option characters.
- If an option character is seen that is not listed in OPTSTRING,
- return '?' after printing an error message. If you set `opterr' to
- zero, the error message is suppressed but we still return '?'.
-
- If a char in OPTSTRING is followed by a colon, that means it wants an arg,
- so the following text in the same ARGV-element, or the text of the following
- ARGV-element, is returned in `optarg'. Two colons mean an option that
- wants an optional arg; if there is text in the current ARGV-element,
- it is returned in `optarg', otherwise `optarg' is set to zero.
-
- If OPTSTRING starts with `-' or `+', it requests different methods of
- handling the non-option ARGV-elements.
- See the comments about RETURN_IN_ORDER and REQUIRE_ORDER, above.
-
- Long-named options begin with `--' instead of `-'.
- Their names may be abbreviated as long as the abbreviation is unique
- or is an exact match for some defined option. If they have an
- argument, it follows the option name in the same ARGV-element, separated
- from the option name by a `=', or else the in next ARGV-element.
- When `getopt' finds a long-named option, it returns 0 if that option's
- `flag' field is nonzero, the value of the option's `val' field
- if the `flag' field is zero.
-
- The elements of ARGV aren't really const, because we permute them.
- But we pretend they're const in the prototype to be compatible
- with other systems.
-
- LONGOPTS is a vector of `struct option' terminated by an
- element containing a name which is zero.
-
- LONGIND returns the index in LONGOPT of the long-named option found.
- It is only valid when a long-named option has been found by the most
- recent call.
-
- If LONG_ONLY is nonzero, '-' as well as '--' can introduce
- long-named options. */
