 Clients may be implemented in any language that is capable of writing
 and receiving data over TCP socket.  A [reference client] is provided.
 Clients may be implemented both synchronously and asynchronously,
 although the latter is impossible in protocol levels 2 and earlier
 due to the lack of message sequencing.
