---------------------------------------------------------------
they caused trouble for me because the same files are also in the slf4j-api
jar. i was using sbt assembly to build a super-jar (jar with all compile
dependencies included) and it threw an error because it didn't know how to
handle these duplicates.
also besides super-jars, people in general might include their own slf4j
version. i know we do. these files might potentially provide the wrong
information if they clobber the ones included with a slf4j dependency? not
sure...
