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

### Linux
For Linux users, pre-built binary packages are available for most distributions.
Note that DRAFT APIs can change at any time without warning, pick a STABLE build to
avoid having them enabled.
