Upgrade note: You will have to disable all Science Project modules before upgrading to this new version! The core features of Mechanics are parts and extensibility hooks for building all kinds of any-multiplicity relationships (connectors) between content items. The UI is heavily customizable and extensible, leveraging the separate Origami module (which is required). Then there are additional features for pushing connected content to zones (Paperclips), managing and customizing edit links and other actions (Impulses), and advanced item routing (Plumbing). Now including a recipe which will install the required Origami dependency for you.
