Google app engine datastore "low level api" for Java examples, tutorials, documentation?

Question

Any suggestions on where to find examples, tutorials, and more thorough documentation on how to use the Google App Engine Datastore "Low Level Api" for Java?

I know this basic documentation page exists, but it just tells me whats in the Api and doesn't say much about how to actually use it: http://code.google.com/appengine/docs/java/javadoc/com/google/appengine/api/datastore/package-summary.html

Thanks! Chris

I don't know if this articles fit here, but covers in a very technical way the datastore.
