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

such that no overflow shall occur.
