NNG, like its predecessors nanomsg (and to some extent ZeroMQ), is a
lightweight, broker-less library, offering a simple API to solve common
recurring messaging problems, such as publish/subscribe, RPC-style
request/reply, or service discovery. The API frees the programmer from
worrying about details like connection management, retries, and other
common considerations, so that they can focus on the application instead
of the plumbing.

NNG is implemented in C, requiring only C99 and CMake to build. It can
be built as a shared or a static library, and is readily embeddable. It
is also designed to be easy to port to new platforms if your platform is
not already supported.

This is version 1.X of nng.
