This is a demo app for the unified storage API in RingoJS. If run on Google App Engine the app will use the Google's Datastore binding defined in the ringo/storage/googlestore module. See http://ringojs.org/wiki/Screencasts/ for a short screencast on on how to run RingoJS applications on Google App Engine. Otherwise, the app will use ringo/storage/filestore as database backend, a simple file based persistence engine that uses JSON as its data format.
