[jdc] now has updated Tcl bindings for ZeroMQ 2.1 & 3.1, see [ZeroMQ].
**Project Description**
[http://www.zeromq.org/%|%ZeroMQ] is a light-weight messaging system with bindings for 20+ languages. A Tcl extension was
developed for ZeroMQ 1.x, but has not been maintained. ZeroMQ 2.x is the current version of the library, with version
3.x on the horizon.
The goal of this project is two fold.
First, update the Tcl bindings for ZeroMQ 2.x.
Second, write examples for [http://zguide.zeromq.org/page:all%|%ZGuide], a tutorial for using ZeroMQ.
ZGuide implementations exist for many of the existing languages supported by ZeroMQ.

**Comments & Discussion**
[EB]: This is something I had in mind last year, but I hadn't the time to start something.
One requirement for the Tcl binding is the encapsulation of the asynchronous API into the event loop.
This is a feature which will make this binding superior to other language bindings.
