Ok... Though some kind of logging configuration, even a default one, is always present. For example, when logging.info() module method --or some one similar-- is called for the first time, it creates a basic logger with a last resort handler if none exists --at least up to my knowledge. So automatic set up, but set up indeed.
In any case... most important to me... I do not really know nothing about comprehensive logging. I made a search on web and on my books but does not find anything useful. Could you provide me any link or additional information on that matter, please?
