cppzmq is a C++ binding for libzmq. It has the following design goals:

* cppzmq maps the libzmq C API to C++ concepts. In particular:
  - it is type-safe (the libzmq C API exposes various class-like
    concepts as void*)
  - it provides exception-based error handling (the libzmq C API
    provides errno-based error handling)
  - it provides RAII-style classes that automate resource management
    (the libzmq C API requires the user to take care to free resources
    explicitly)
* cppzmq is a light-weight, header-only binding. You only need to
  include the header file zmq.hpp (and maybe zmq_addon.hpp) to use it.
* zmq.hpp is meant to contain direct mappings of the abstractions
  provided by the libzmq C API, while zmq_addon.hpp provides additional
  higher-level abstractions.
