/* This version of `getopt' appears to the caller like standard Unix `getopt'

As `getopt' works, it permutes the elements of ARGV so that,
95
when it is done, all the options precede everything else. Thus
96
all application programs are extended to handle flexible argument order.

Setting the environment variable POSIXLY_CORRECT disables permutation.

If the caller did not specify anything,

the default is REQUIRE_ORDER if the environment variable

POSIXLY_CORRECT is defined, PERMUTE otherwise.
161
REQUIRE_ORDER means don't recognize them as options;
162
stop option processing when the first non-option is seen.
163
This is what Unix does.
164
This mode of operation is selected by either setting the environment
165
variable POSIXLY_CORRECT, or using `+' as the first character
166
of the list of option characters.
168
PERMUTE is the default. We permute the contents of ARGV as we scan,
169
so that eventually all the non-options are at the end. This allows options
170
to be given in any order, even with programs that were not written to
173
RETURN_IN_ORDER is an option available to programs that were written
174
to expect options and other ARGV-elements in any order and that care about
175
the ordering of the two. We describe each non-option ARGV-element
176
as if it were the argument of an option with character code 1.
177
Using `-' as the first character of the list of option characters
178
selects this mode of operation.
180
The special argument `--' forces an end of option-scanning regardless
181
of the value of `ordering'. In the case of RETURN_IN_ORDER, only

`--' can cause `getopt' to return -1 with `optind' != ARGC. */

/* Scan elements of ARGV (whose length is ARGC) for option characters
464
If an element of ARGV starts with '-', and is not exactly "-" or "--",
465
then it is an option element. The characters of this element
466
(aside from the initial '-') are option characters. If `getopt'
467
is called repeatedly, it returns successively each of the option characters
468
from each of the option elements.
470
If `getopt' finds another option character, it returns that character,
471
updating `optind' and `nextchar' so that the next call to `getopt' can
472
resume the scan with the following option character or ARGV-element.
474
If there are no more option characters, `getopt' returns -1.
475
Then `optind' is the index in ARGV of the first ARGV-element
476
that is not an option. (The ARGV-elements have been permuted
477
so that those that are not options now come last.)
479
OPTSTRING is a string containing the legitimate option characters.
480
If an option character is seen that is not listed in OPTSTRING,
481
return '?' after printing an error message. If you set `opterr' to
482
zero, the error message is suppressed but we still return '?'.
484
If a char in OPTSTRING is followed by a colon, that means it wants an arg,
485
so the following text in the same ARGV-element, or the text of the following
486
ARGV-element, is returned in `optarg'. Two colons mean an option that
487
wants an optional arg; if there is text in the current ARGV-element,
488
it is returned in `optarg', otherwise `optarg' is set to zero.
490
If OPTSTRING starts with `-' or `+', it requests different methods of
491
handling the non-option ARGV-elements.
492
See the comments about RETURN_IN_ORDER and REQUIRE_ORDER, above.
494
Long-named options begin with `--' instead of `-'.
495
Their names may be abbreviated as long as the abbreviation is unique
496
or is an exact match for some defined option. If they have an
497
argument, it follows the option name in the same ARGV-element, separated
498
from the option name by a `=', or else the in next ARGV-element.
499
When `getopt' finds a long-named option, it returns 0 if that option's
500
`flag' field is nonzero, the value of the option's `val' field
501
if the `flag' field is zero.
503
The elements of ARGV aren't really const, because we permute them.
504
But we pretend they're const in the prototype to be compatible
507
LONGOPTS is a vector of `struct option' terminated by an
508
element containing a name which is zero.
510
LONGIND returns the index in LONGOPT of the long-named option found.
511
It is only valid when a long-named option has been found by the most
