zmq frontend

Hello,

Trying to run the zmq frontend.py to test the kernalapp.py

I get this

system-process:zmq ericjang$ python frontend.py

frontend.py is long-dead code, and not used by anything (I just opened PR #3366 to remove it). Where did you get the idea of using it as a test?

trying to learn how to build a frontend for the iPython kernel in a
different language (Obj-C) using the Obj-C zmq bindings. The comment said

"A simple interactive frontend that talks to a kernel over 0MQ." so I
thought it might have been a good place to start learning.

That's logical enough, sorry for the confusion. That code should never have been in any released version of IPython. The TerminalInteractiveShell, QtConsole, or even the KernelClient tests are probably better places to look.

No worries, thanks for your prompt reply and for maintaing such an awesome,
well-commented specimen of open source!
