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

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

It tokenize the content of the paste and publish the result in the following
format:
    channel_name+' '+/path/of/the/paste.gz+' '+tokenized_word+' '+scoring

    ..seealso:: Paste method (_get_top_words)

..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_PubSub_Tokenize_Q Module running to be able to work properly.
