+=======================================================================
+The AcitveMQ Protocol Buffers Java Implementation
+=======================================================================
+
+Protocol Buffers is a data interchange format developed by 
+Google.  You can get more information about Protocol Buffers
+at:
+
+ http://code.google.com/apis/protocolbuffers/
+
+
+Unfortunately the the main Protocol Buffer's project made the 
+Java API cumbersome to use since the messages are immutable.  They
+Justify this decision by highlighting the fact it reduces end user
+error that occur with Mutable messages.
+
+This module brings you a slimmed down lean and mean API to accessing
+Protocol Buffer data structures.  It provides little protection
+from end users 'hurting themselves', but it does give power user
+and easier to use API.
+
+In addition, this module provides a Java based code generator so 
+that it's easier to code generate your Protocol Buffer classes in 
+a java based build system like Ant or Maven.
