+    <para>The Apache Accumulo sorted, distributed key/value store
+    is a robust, scalable, high performance data storage and
+    retrieval system. Apache Accumulo is based on Google's BigTable
+    design and is built on top of Apache Hadoop, Zookeeper, and
+    Thrift. Apache Accumulo features a few novel improvements on
+    the BigTable design in the form of cell-based access control
+    and a server-side programming mechanism that can modify
+    key/value pairs at various points in the data management
+    process.</para>
