Deploying a Ruby on Rails 2 application is like this: git clone ... (or hg pull ... or whatever you use) rake gems:install (this installs all the libraries your project depend on) rake db:create rake db:migrate rake db:seed
Very, very convenient. Otherwise you have to download the jars in you server, or commit them to your source control which is pretty heavy. In D, Java, C#, etc., it's a PITA, specially when your app depends on a specific version of a library.
