Ruby on Rails. You'll immediately notice an 'app' directory. Resources are in app/assets, controllers in app/controllers, models in app/models and views in app/views. There's a routes.rb file and a command line interface ('rake routes' does the same as 'php artisan routes:list', 'rake db:migrate' is the same as 'php artisan migrate').

While you can deploy Rails by just copying files (it will reload classes and recompile assets on page refresh whenever possible) it's still a best practice to have the dev and production environment different.
