 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.
 .
 This package provides a library for the Haskell programming language.
