Subject: ignoring invalid options with optparse

I have some code that looks like this:

  def go!
    options = {}
    return if not ARGV.options do |opts|
      exit = true
      opts.on_tail("--help", "show this message") { |exit| puts opts; }
      opts.on('--logfile=LOGFILE', String) { |options[:logfile]| }
      opts.parse!
      !exit
    end

    orb = CORBA::ORB_init($0, ARGV)

    # ...
  end

I'd like for optparse to ignore invalid options so that I can pass them
to ORB_init.  Is this possible?

Also, I noticed that getoptlong lets me use:
  ruby foo.rb --opt arg

but optparse requires:
  ruby foo.rb --opt=arg

Is it possible to get optparse to allow the form without '='?

Thanks,

Paul
