OptionParser raises an OptionParser::InvalidOption, which has
erred option in args.

  others = []
  ARGV.options do |opt|
    opt.on("--foo=BAR") {|foo| puts "foo option #{foo}"}
    begin
      opt.parse!
    rescue OptionParser::InvalidOption => e
      others.concat(e.args)
    end
  end
  exec("your command", *ohters)
