++/* Scan elements of ARGV (whose length is ARGC) for option characters

++
++ 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 -1.
++ 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.
++
++ 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.
++
++ If POSIXLY_CORRECT is nonzero, behave as if the POSIXLY_CORRECT
++ environment variable were set. */
