Uses DNS Service Discovery (a.k.a. mDNS or Bonjour) to advertise a Rails server on the local network. This primarily exists to make it easy to connect to a development server from a remote host without having to look up your IP address.
Just add the train_whistle gem to your application's Gemfile, preferably in the development group.
group :development do
gem 'train_whistle', :git => 'https://github.com/benzado/train_whistle.git'
end
That's it. The gem uses a Railtie to load itself automatically. There is no configuration (yet).
