+SUMMARY="A fast key-value storage library written at Google"
+DESCRIPTION="LevelDB stores keys and values in arbitrary byte arrays, and \
+data is sorted by key. It supports batching writes, forward and backward \
+iteration, and compression of the data via Google's Snappy compression \
+library.
+LevelDB is not an SQL database. Like other NoSQL and Dbm stores, it does \
+not have a relational data model and it does not support SQL queries. Also, \
+it has no support for indexes. Applications use LevelDB as a library, as it \
+does not provide a server or command-line interface."
