Rails::Engine allows you to wrap a specific Rails application or subset of functionality and share it with other applications or within a larger packaged application. Every Rails::Application is just an engine, which allows for simple feature and application sharing.

Any Rails::Engine is also a Rails::Railtie, so the same methods (like rake_tasks and generators) and configuration options that are available in railties can also be used in engines.
