+OCaml-values in a type-safe binary protocol.  It is extremely efficient,
+typically supporting type-safe marshalling and unmarshalling of even highly
+structured values at speeds sufficient to saturate a gigabit connection.  The
+protocol is also heavily optimized for size, making it ideal for long-term
+storage of large amounts of data.")
