I am using Maven. But as I said I could not find the Atomikos in any
public library, putting them in lib will let the user easily install
them in their local repo.
Do you know if they are in any public repo?
Sorry about the license issues, didn't think about that.
I can remove them all in any case, even though that would make it
harder to use.

First I like the printf-style logging API, similar to slf4j. Nice to
use plus better performance.
Second I really like Configgys configuration API, plus that it is
integrated with the logging.
But this was just a comment from my side, I have no problem whatsoever
to use Lift logger.
