[Goffi]

Sorry, the recommandation are wrong, I forgot that ConfigParser do substitution 
(so you need to escape the %), and quote must no be present. So the correct 
recommandations are as follow:


recommandations:
*****************
	The default options are alright for production. If you want to develop,
you can use something like:

	[DEFAULT]
	log_level=debug
	log_fmt=[%%(name)s {%%(profile)s}] %%(message)s

	[primitivus]
	log_level=debug
	log_fmt=%%(level)s: %%(message)s

	[wix]
	log_level=debug
	log_fmt=[%%(name)s] %(message)s
