libxs-compat-libzmq-dev 1.2.0-1.1 (arm64 binary) in ubuntu trusty

 Crossroads I/O ("libxs") is a library for building scalable and high
 performance distributed applications. It fits between classic BSD sockets,
 JMS/AMQP-style message queues, and enterprise message-oriented middleware.
 .
 Crossroads I/O extends the standard socket interfaces with features
 traditionally provided by specialised messaging middleware products,
 providing an abstraction of asynchronous message queues, multiple messaging
 patterns, message filtering (subscriptions), seamless access to multiple
 transport protocols, and more.
 .
 This package contains the development library and header files for the
 drop-in 'libzmq' compatibility library for ZeroMQ language bindings and
 applications.
