      Continuous testing for your ruby app.
        Autotest automatically tests code that has changed. It assumes
        the code is in lib, and tests are in test/test_*.rb. Autotest
        uses plugins to control what happens. You configure plugins
        with require statements in the .autotest file in your
        project base directory, and a default configuration for all
        your projects in the .autotest file in your home directory.
      Usage:
          autotest [options]
    BANNER
    opts.on "-d", "--debug", "Debug mode, for reporting bugs." do
      require "pp"
      options[:debug] = true
    end
    opts.on "-v", "--verbose", "Be annoyingly verbose (debugs .autotest)." do
      options[:verbose] = true
    end
    opts.on "-q", "--quiet", "Be quiet." do
      options[:quiet] = true
    end
    opts.on("-r", "--rc CONF", String, "Override path to config file") do |o|
      options[:rc] = Array(o)
    end
    opts.on("-w", "--warnings", "Turn on ruby warnings") do
      $-w = true
    end
    opts.on "-h", "--help", "Show this." do
      puts opts
      exit 1
