I would think that any program sufficiently large to warrant 
configuration files (or another non-hardcoded configuration machanism) 
probably already has one in place. And probably the worst thing you can 
do to the person administrating the software is adding different 
configuration methods. So I think the library should offer an API that 
allows configuration, but leave the usage of this API up to the user.

One thing i would advise though is the possiblity to change these 
paramters on the fly (which should be easy using an API). So that log 
levels could be increased or decreased based on what is going on for 
example.
