          Deploys and starts a `cold' application. This is useful if you have not \
          deployed your application before, or if your application is (for some \
          other reason) not currently running. It will deploy the code, run any \
          pending migrations, and then instead of invoking `deploy:restart', it \
          will invoke `deploy:start' to fire up the application servers.

          [NOTE] This overides the capistrano default by calling the "db:seed" \
          task, if it is defined.
