+	  The RocksDB library provides a persistent key value store.
+	  Keys and values are arbitrary byte arrays. The keys are
+	  ordered within the key value store according to a
+	  user-specified comparator function.
+
+	  The library is maintained by the Facebook Database Engineering
+	  Team, and is based on LevelDB, by Sanjay Ghemawat and Jeff
+	  Dean at Google.
