+-/* Scan elements of ARGV (whose length is ARGC) for option characters
+- given in OPTSTRING.
+-
+- 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.
+-
+- 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. */
