"""
The ZMQ_PubSub_Lines Module
============================

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

It perform a sorting on the line's length and publish/forward them to
differents channels:

*Channel 1 if max length(line) < max
*Channel 2 if max length(line) > max

The collected informations about the processed pastes
(number of lines and maximum length line) are stored 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. (LevelDB & Redis)
*Need the ZMQ_PubSub_Line_Q Module running to be able to work properly.
