devel/avro/pkg-descr

+Avro is a data serialization system.
+
+Avro provides:
+* Rich data structures.
+* A compact, fast, binary data format.
+* A container file, to store persistent data.
+* Remote procedure call (RPC).
+* Simple integration with dynamic languages. Code generation is not
+required to read or write data files nor to use or implement RPC
+protocols. Code generation as an optional optimization, only worth
+implementing for statically typed languages.
