+ From the ZeroMQ manpage 'zmq':
+
+ The 0MQ lightweight messaging kernel is a library which extends the standard
+ socket interfaces with features traditionally provided by specialised
+ messaging middleware products. 0MQ sockets provide an abstraction of
+ asynchronous message queues, multiple messaging patterns, message filtering
+ (subscriptions), seamless access to multiple transport protocols and more.
