guard-rails/README.md

Want to restart your Rails dev server whilst you work? Now you can!

guard 'rails', :port => 5000 do
  watch('Gemfile.lock')
  watch(%r{^(config|lib)/.*})
end

Three fun options!

• :port is the port number to run on (default 3000)
• :environment is the environment to use (default development)
• :start_on_start will start the server when starting Guard (default true)

This is super-alpha, but it works for me!
