Czmq (previously known as libzapi) provides a high-level c binding for 0mq, a lightweight messaging library.

this library provides higher level abstractions on top of the base library, with features such as:
* work with messages as strings, individual frames, or multipart messages.
* automatic closure of any open sockets at context termination.
* automatic linger configuration of all sockets for context termination.
* portable api for creating child threads and ?mq pipes to talk to them.
* simple reactor with one-off and repeated timers, and socket readers.
* system clock functions for sleeping and calculating timers.
* easy api to get/set all socket options.
* includes generic hash and list containers.
this package provides the debugging symbols for czmq.
