It's a [Guard](http://github.com/guard/guard) for the [Rocco](http://github.com/rtomayko/rocco) documentation system!

    guard 'rocco' do
      watch(%r{^app/.*\.(rb|coffee)$})
      watch(%r{^lib/.*\.rb$})
    end

Only one option for now:

* `:dir` specifies the output dir (default `doc`)

`gem install guard-rocco` or Bundle it up with `gem 'guard-rocco'`. Then `guard init rocco`. Yeah!
