I wonder what the nicest strategy for this kind of stuff is, where we have
support for multiple loggers but don't want to ship the jars by default.
Maybe we need to have a lib folder or something that we deploy
automatically? Or just instructions as to where to put those jar(s) so
they're on the class-path.
