+Pylru provides a cache class with a simple dict interface.  It also provides
+classes to wrap any object that has a dict interface with a cache.  Both
+write-through and write-back semantics are supported.  Pylru also provides
+classes to wrap functions in a similar way, including a function decorator.")
