-// Package dummy comtains dummy implementations of:
-//   * gae.RawDatastore
-//   * gae.Memcache
-//   * gae.TaskQueue
-//   * gae.GlobalInfo
-//   * gae.DSQuery
-//
-// These dummy implementations panic with an appropriate error message when
-// any of their methods are called. The message looks something like:
-//   dummy: method Interface.Method is not implemented
-//
-// The dummy implementations are useful when implementing the interfaces
-// themselves, or when implementing filters, since it allows your stub
-// implementation to embed the dummy version and then just implement the methods
-// that you care about.
