4039          * This is a gross hack.  There really aren't many other good
4040          * options (excuse the pun) for parsing options in a situation like
4041          * this.  getopt is kinda braindead, so you end up having to run
4042          * through the options twice, and give each invocation of getopt
4043          * the option string for the other invocation.
4044          *
4045          * You would think that you could just have two groups of options.
4046          * The first group would get parsed by the first invocation of
4047          * getopt, and the second group would get parsed by the second
4048          * invocation of getopt.  It doesn't quite work out that way.  When
4049          * the first invocation of getopt finishes, it leaves optind pointing
4050          * to the argument _after_ the first argument in the second group.
4051          * So when the second invocation of getopt comes around, it doesn't
4052          * recognize the first argument it gets and then bails out.
4053          *
4054          * A nice alternative would be to have a flag for getopt that says
4055          * "just keep parsing arguments even when you encounter an unknown
4056          * argument", but there isn't one.  So there's no real clean way to
4057          * easily parse two sets of arguments without having one invocation
4058          * of getopt know about the other.
4059          *
4060          * Without this hack, the first invocation of getopt would work as
4061          * long as the generic arguments are first, but the second invocation
4062          * (in the subfunction) would fail in one of two ways.  In the case
4063          * where you don't set optreset, it would fail because optind may be
4064          * pointing to the argument after the one it should be pointing at.
4065          * In the case where you do set optreset, and reset optind, it would
4066          * fail because getopt would run into the first set of options, which
4067          * it doesn't understand.
4068          *
4069          * All of this would "sort of" work if you could somehow figure out
4070          * whether optind had been incremented one option too far.  The
4071          * mechanics of that, however, are more daunting than just giving
4072          * both invocations all of the expect options for either invocation.
4073          *
4074          * Needless to say, I wouldn't mind if someone invented a better
4075          * (non-GPL!) command line parsing interface than getopt.  I
4076          * wouldn't mind if someone added more knobs to getopt to make it
4077          * work better.  Who knows, I may talk myself into doing it someday,
4078          * if the standards weenies let me.  As it is, it just leads to
