It's a Guard for the Rocco documentation system!

# default values
guard 'rocco', :run_on => [:start, :change], :dir => 'doc', :stylesheet => 'http://jashkenas.github.com/docco/resources/docco.css' do
  watch(%r{^app/.*\.(rb|coffee)$})
  watch(%r{^lib/.*\.rb$})
end

Options:

• :run_on specifies when to update the docs
  • :start - run on all documentation when the guard starts
  • :change - run when watched files change
  • :reload - run when the guard is reloaded
  • :all - run when running all the guards
• :dir specifies the output dir
• :stylesheet specifies a custom stylesheet to use

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