+may be encoded to and from binary formats, written to disk as binary, or sent over
+the network.  The format used can be automatically generated, or you can choose to
+implement a custom format if needed.  Serialisation speeds of over 1 G\\/sec have
+been observed, so this library should be suitable for high performance scenarios.")
