1879	 * Ahh, getopt(3) is a pain.
1880	 *
1881	 * This is a gross hack.  There really aren't many other good
1882	 * options (excuse the pun) for parsing options in a situation like
1883	 * this.  getopt is kinda braindead, so you end up having to run
1884	 * through the options twice, and give each invocation of getopt
1885	 * the option string for the other invocation.
1886	 *
1887	 * You would think that you could just have two groups of options.
1888	 * The first group would get parsed by the first invocation of
1889	 * getopt, and the second group would get parsed by the second
1890	 * invocation of getopt.  It doesn't quite work out that way.  When
1891	 * the first invocation of getopt finishes, it leaves optind pointing
1892	 * to the argument _after_ the first argument in the second group.
1893	 * So when the second invocation of getopt comes around, it doesn't
1894	 * recognize the first argument it gets and then bails out.
1895	 *
1896	 * A nice alternative would be to have a flag for getopt that says
1897	 * "just keep parsing arguments even when you encounter an unknown
1898	 * argument", but there isn't one.  So there's no real clean way to
1899	 * easily parse two sets of arguments without having one invocation
1900	 * of getopt know about the other.
1901	 *
1902	 * Without this hack, the first invocation of getopt would work as
1903	 * long as the generic arguments are first, but the second invocation
1904	 * (in the subfunction) would fail in one of two ways.  In the case
1905	 * where you don't set optreset, it would fail because optind may be
1906	 * pointing to the argument after the one it should be pointing at.
1907	 * In the case where you do set optreset, and reset optind, it would
1908	 * fail because getopt would run into the first set of options, which
1909	 * it doesn't understand.
1910	 *
1911	 * All of this would "sort of" work if you could somehow figure out
1912	 * whether optind had been incremented one option too far.  The
1913	 * mechanics of that, however, are more daunting than just giving
1914	 * both invocations all of the expect options for either invocation.
1915	 *
1916	 * Needless to say, I wouldn't mind if someone invented a better
1917	 * (non-GPL!) command line parsing interface than getopt.  I
1918	 * wouldn't mind if someone added more knobs to getopt to make it
1919	 * work better.  Who knows, I may talk myself into doing it someday,
1920	 * if the standards weenies let me.  As it is, it just leads to
1921	 * hackery like this and causes people to avoid it in some cases.
