Roboconf takes in input application descriptions.An application description is a zip archive which includes a list of software components and their relations (what is deployed on what and what depends on what). Each component comes with recipes that will be used to handle its life cycle. Beyond the classical phases (deploy, start, stop and un deploy), there is a special phase called "update". It is invoked every time a dependency changes.
