/* Unlike standard Unix `getopt', functions like `getopt_long'

let the user intersperse the options with the other arguments.
50
As `getopt_long' works, it permutes the elements of ARGV so that,
51
when it is done, all the options precede everything else. Thus
52
all application programs are extended to handle flexible argument order.
54
Using `getopt' or setting the environment variable POSIXLY_CORRECT
56
Then the application's behavior is completely standard.

/* Scan elements of ARGV (whose length is ARGC) for option characters
296
If an element of ARGV starts with '-', and is not exactly "-" or "--",
297
then it is an option element. The characters of this element
298
(aside from the initial '-') are option characters. If `getopt'
299
is called repeatedly, it returns successively each of the option characters
300
from each of the option elements.
302
If `getopt' finds another option character, it returns that character,
303
updating `optind' and `nextchar' so that the next call to `getopt' can
304
resume the scan with the following option character or ARGV-element.
306
If there are no more option characters, `getopt' returns -1.
307
Then `optind' is the index in ARGV of the first ARGV-element
308
that is not an option. (The ARGV-elements have been permuted
309
so that those that are not options now come last.)
311
OPTSTRING is a string containing the legitimate option characters.
312
If an option character is seen that is not listed in OPTSTRING,
313
return '?' after printing an error message. If you set `opterr' to
314
zero, the error message is suppressed but we still return '?'.
316
If a char in OPTSTRING is followed by a colon, that means it wants an arg,
317
so the following text in the same ARGV-element, or the text of the following
318
ARGV-element, is returned in `optarg'. Two colons mean an option that
319
wants an optional arg; if there is text in the current ARGV-element,
320
it is returned in `optarg', otherwise `optarg' is set to zero.
322
If OPTSTRING starts with `-' or `+', it requests different methods of
323
handling the non-option ARGV-elements.
324
See the comments about RETURN_IN_ORDER and REQUIRE_ORDER, above.
326
Long-named options begin with `--' instead of `-'.
327
Their names may be abbreviated as long as the abbreviation is unique
328
or is an exact match for some defined option. If they have an
329
argument, it follows the option name in the same ARGV-element, separated
330
from the option name by a `=', or else the in next ARGV-element.
331
When `getopt' finds a long-named option, it returns 0 if that option's
332
`flag' field is nonzero, the value of the option's `val' field
333
if the `flag' field is zero.
335
LONGOPTS is a vector of `struct option' terminated by an
336
element containing a name which is zero.
338
LONGIND returns the index in LONGOPT of the long-named option found.
339
It is only valid when a long-named option has been found by the most
342
If LONG_ONLY is nonzero, '-' as well as '--' can introduce
345
If POSIXLY_CORRECT is nonzero, behave as if the POSIXLY_CORRECT
346
environment variable were set. */
