4280 	 * Ahh, getopt(3) is a pain.
4281 	 *
4282 	 * This is a gross hack.  There really aren't many other good
4283 	 * options (excuse the pun) for parsing options in a situation like
4284 	 * this.  getopt is kinda braindead, so you end up having to run
4285 	 * through the options twice, and give each invocation of getopt
4286 	 * the option string for the other invocation.
4287 	 *
4288 	 * You would think that you could just have two groups of options.
4289 	 * The first group would get parsed by the first invocation of
4290 	 * getopt, and the second group would get parsed by the second
4291 	 * invocation of getopt.  It doesn't quite work out that way.  When
4292 	 * the first invocation of getopt finishes, it leaves optind pointing
4293 	 * to the argument _after_ the first argument in the second group.
4294 	 * So when the second invocation of getopt comes around, it doesn't
4295 	 * recognize the first argument it gets and then bails out.
4296 	 *
4297 	 * A nice alternative would be to have a flag for getopt that says
4298 	 * "just keep parsing arguments even when you encounter an unknown
4299 	 * argument", but there isn't one.  So there's no real clean way to
4300 	 * easily parse two sets of arguments without having one invocation
4301 	 * of getopt know about the other.
4302 	 *
4303 	 * Without this hack, the first invocation of getopt would work as
4304 	 * long as the generic arguments are first, but the second invocation
4305 	 * (in the subfunction) would fail in one of two ways.  In the case
4306 	 * where you don't set optreset, it would fail because optind may be
4307 	 * pointing to the argument after the one it should be pointing at.
4308 	 * In the case where you do set optreset, and reset optind, it would
4309 	 * fail because getopt would run into the first set of options, which
4310 	 * it doesn't understand.
4311 	 *
4312 	 * All of this would "sort of" work if you could somehow figure out
4313 	 * whether optind had been incremented one option too far.  The
4314 	 * mechanics of that, however, are more daunting than just giving
4315 	 * both invocations all of the expect options for either invocation.
4316 	 *
4317 	 * Needless to say, I wouldn't mind if someone invented a better
4318 	 * (non-GPL!) command line parsing interface than getopt.  I
4319 	 * wouldn't mind if someone added more knobs to getopt to make it
4320 	 * work better.  Who knows, I may talk myself into doing it someday,
4321 	 * if the standards weenies let me.  As it is, it just leads to
4322 	 * hackery like this and causes people to avoid it in some cases.
