"""
The ZMQ_Feed_Q Module
=====================
This module is the first of the ZMQ tree processing.
It's subscribe to a data stream and put the received messages
into a Redis-list waiting to be popped later by others scripts
..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.
*Messages from the stream should be formated as follow:
"channel_name"+" "+/path/to/the/paste.gz+" "base64_data_encoded_paste"
