+%description
+A consensus library that supports creating multiple consensus groups
+(ensembles). Each ensemble is a separate Multi-Paxos instance with its own
+leader, set of members, and state.
+
+Each ensemble also supports an extended API that provides consistent key/value
+operations. Conceptually, this is identical to treating each key as a separate
+Paxos entity. However, this isn't accomplished by having each key maintain its
+own Paxos group. Instead, an ensemble emulates per-key consensus through a
+combination of per-key and per-ensemble state.
