gaeutilities is a collection of classes to aid in development on Google Appengine.

The stable version includes the following classes.

Session: An http session class to preserve identity across http requests. It uses both BigTable and Memcache for performance and reliability. It also includes middleware to plug in with django.

Cache: A BigTable and Memcache caching class. Any object that can be pickled can be stored in cache.

Event: A subscribe/fire event system that gives developers the ability to set callback functions.

Flash: A cookie based messaging library. Using json, data structures can be stored as a cookie in the browser and retrieved on the next request. Useful for messages such as "Thank you for logging in."
