+    Direct buffer pool implementation used by Eve's frontend
+    </shortDescription>
+
+    <description>
+        A pool of direct memory buffer pools of fixed size.  These resouces
+        are expensive to create and destroy unlike regular memory allocated
+        on the Java heap direct memory buffers are allocated outside of the
+        Java managed memory space.  The garbage collector does not apply to
+        direct allocated buffers.  As a consequence it is very costly to 
+        allocate and free direct buffers.  These resources are ideal candidates
+        for pooling.  This is the purpose for this service.
