"""
The ZMQ_Feed_Q Module
=====================

This module is consuming the Redis-list created by the ZMQ_Feed_Q Module,
And save the paste on disk to allow others modules to work on them.

..todo:: Be able to choose to delete or not the saved paste after processing.
..todo:: Store the empty paste (unprocessed) somewhere in Redis.

..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.
*Need the ZMQ_Feed_Q Module running to be able to work properly.
