Agreed. It's on my todo list to add more examples ...

A configuration file is not really needed for simple configurations.
For the simplest usage,  the minimal example at

http://www.python.org/dev/doc/devel/lib/minimal-example.html

should suffice.

Take a look at the link above. You cannot code logging much more
simply than that.

Documentation can always be improved. Patches are always welcome! I
will look at adding Ville's simple use case to the documentation as my
next documentation activity.
