That's partly why logging hasn't made much effort in the "default" department:
everyone wants something different.

I think he just means that he can't use basicConfig because it just sets the
root logger's level to whatever's passed in, but what he actually wants to set
are two different levels: INFO on the logger, WARNING on the stderr handler.
On top of that, he wants to have a stdout handler which only outputs INFO
events, and to get that effect he has to add the filter to the stdout handler
(otherwise it would output INFO + anything at a higher level, too).

It's possible that perhaps there could be some 'canned configs', as I've
mentioned in another post on this thread. Some more thinking needs to be done
around this area.
