+
+	  Apache 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.
