"""
The ZMQ_Sub_Onion Module
============================

This module is consuming the Redis-list created by the ZMQ_Sub_Onion_Q Module.

It trying to extract url from paste and returning only ones which are tor related
(.onion)

    ..seealso:: Paste method (get_regex)

..note:: Module ZMQ_Something_Q and ZMQ_Something are closely bound, always put
the same Subscriber name in both of them.

Requirements
------------

*Need running Redis instances. (Redis)
*Need the ZMQ_Sub_Onion_Q Module running to be able to work properly.
