 PyZMQ
 -----
 
-`PyZMQ <http://zeromq.github.com/pyzmq/>`_ is the Python binding for `ZeroMQ <http://www.zeromq.org/>`_,
-which is a high-performance asynchronous messaging library. One great advantage is that ZeroMQ
-can be used for message queuing without a message broker. The basic patterns for this are:
-
-- request-reply: connects a set of clients to a set of services. This is a remote procedure call
-  and task distribution pattern.
-- publish-subscribe: connects a set of publishers to a set of subscribers. This is a data
-  distribution pattern.
-- push-pull (or pipeline): connects nodes in a fan-out / fan-in pattern that can have multiple
-  steps, and loops. This is a parallel task distribution and collection pattern.
