NetMQ is an industrial-strength, high-performance implementation of the Advanced Messaging Queueing Protocol (AMQP.) NetMQ is written in the C programming language for use on POSIX-compliant systems. The NetMQ system consists of a server progam, a client program which allows interaction with the server via a command-line interface, a shared library containing server functions, a shared library containing client functions, and C header files for use in developing software which interface with the NetMQ system. The current version of NetMQ implements the AMQP Standard version 0.8.
