groke6@381:    PERMUTE is the default.  We permute the contents of ARGV as we scan,
groke6@381:    so that eventually all the non-options are at the end.  This allows options

groke6@381:    selects this mode of operation.
groke6@381:

groke6@381: 
groke6@381:    If an element of ARGV starts with '-', and is not exactly "-" or "--",
groke6@381:    then it is an option element.  The characters of this element
groke6@381:    (aside from the initial '-') are option characters.  If `getopt'
groke6@381:    is called repeatedly, it returns successively each of the option characters
groke6@381:    from each of the option elements.
groke6@381: 
groke6@381:    If `getopt' finds another option character, it returns that character,
groke6@381:    updating `optind' and `nextchar' so that the next call to `getopt' can
groke6@381:    resume the scan with the following option character or ARGV-element.
groke6@381: 
groke6@381:    If there are no more option characters, `getopt' returns -1.
groke6@381:    Then `optind' is the index in ARGV of the first ARGV-element
groke6@381:    that is not an option.  (The ARGV-elements have been permuted
groke6@381:    so that those that are not options now come last.)
groke6@381: 
groke6@381:    OPTSTRING is a string containing the legitimate option characters.
groke6@381:    If an option character is seen that is not listed in OPTSTRING,
groke6@381:    return '?' after printing an error message.  If you set `opterr' to
groke6@381:    zero, the error message is suppressed but we still return '?'.
groke6@381: 
groke6@381:    If a char in OPTSTRING is followed by a colon, that means it wants an arg,
groke6@381:    so the following text in the same ARGV-element, or the text of the following
groke6@381:    ARGV-element, is returned in `optarg'.  Two colons mean an option that
groke6@381:    wants an optional arg; if there is text in the current ARGV-element,
groke6@381:    it is returned in `optarg', otherwise `optarg' is set to zero.
groke6@381: 
groke6@381:    If OPTSTRING starts with `-' or `+', it requests different methods of
groke6@381:    handling the non-option ARGV-elements.
groke6@381:    See the comments about RETURN_IN_ORDER and REQUIRE_ORDER, above.
groke6@381: 
groke6@381:    Long-named options begin with `--' instead of `-'.
groke6@381:    Their names may be abbreviated as long as the abbreviation is unique
groke6@381:    or is an exact match for some defined option.  If they have an
groke6@381:    argument, it follows the option name in the same ARGV-element, separated
groke6@381:    from the option name by a `=', or else the in next ARGV-element.
groke6@381:    When `getopt' finds a long-named option, it returns 0 if that option's
groke6@381:    `flag' field is nonzero, the value of the option's `val' field
groke6@381:    if the `flag' field is zero.
groke6@381: 
groke6@381:    The elements of ARGV aren't really const, because we permute them.
groke6@381:    But we pretend they're const in the prototype to be compatible
groke6@381:    with other systems.
groke6@381: 
groke6@381:    LONGOPTS is a vector of `struct option' terminated by an
groke6@381:    element containing a name which is zero.
groke6@381:

groke6@381:    It is only valid when a long-named option has been found by the most
groke6@381:    recent call.
groke6@381:
