Identify the CouchbaseCache and CouchbaseCacheManager classes in the Java Couchbase client.jar

Hi - As a part of this ticket http://support.couchbase.com/tickets/2294 and also in general, we would like to understand how Couchbase Java Client works with Spring

a) Where are we w.r.t Spring and Couchbase ?
b) Caching with spring
c) Full integration for spring data

Please help us with pointers as we could see http://techstickynotes.blogspot.in/2012/04/spring-cache-couchbase-nosql-db.html not being part of any of our documentation, however we could see the two classes being used in one our docs http://www.couchbase.com/docs/couchbase-sdk-java-1.1/couchbase-cache-apis.html
