Studio Api makes it easier to use SuSE Studio (http://susestudio.com) via API. Instead of adapting each ActiveResource to its behavior and manually adding multipart file upload it wrapp in in Active Resource like interface. It is possible to define credentials for whole api, or use it per partes, so it allow using it for different studio users together.
