Overview
--------
   This distribution of Apache OpenJPA builds upon the prior releases which 
   provided a feature-rich implementation of the Java Persistence API (JPA 1.0)
   part of Java Community Process JSR-220 (Enterprise JavaBeans 3.0) by
   includng some Early Access functionality from the Java Community Process
   JSR-317 (JPA 2.0) public draft on 03/13/2009 and is being made available
   for testing and evaluation purposes only. 

   Some of the key features included in this distribution:
     * TBD...

   This early access distribution is based upon the contributions provided in
   development iterations 8 through [TBD], as defined in the JPA 2.0 Roadmap at:
       http://openjpa.apache.org/jpa-20-roadmap.html

   The JPA 2.0 Roadmap contains a complete list of implemented features and
   feature summaries, including what is on deck for future iterations.

Prerequisites
-------------
   In normal usage, OpenJPA requires Java 5 or higher and a relational 
   database of some sort.


Documentation
-------------
   If you have questions about OpenJPA, a good source of information is the
   online product manual. You can find the manual for the current release as
   well as older releases of OpenJPA at
       http://openjpa.apache.org/documentation.html

   If you can't find what you're looking for in the manual or would like more
   clarification you please post to the OpenJPA development mailing list.
   Information on all of the OpenJPA mailing lists may be found here:
