Has it arrived? Seriously - I only hear bad things about it. But  
never used it myself.

Well, if configuration is required then is does not make much sense  
to keep an abstraction ...unless you abstract the configuration away  
and provide different implementations.

CL only makes the assumption that the underlying log library has been  
configured. The XML file you are referring to is (mainly) to  
configure what Log implementation to use.
