Hi,
I wonder if slf4j can support Redwood Logger, which is used in Stanford Natural Language toolkit. I have developed the "slf4j-redwood" to support this logging framework and would like to push a request if necessary.
"Redwood was developed at Stanford by students in the Stanford NLP Group. A tutorial in docs/tutorial.pdf, presented to the group, provides a good introduction to the theory and use of Redwood. It also motivates what types of projects would fit well into the paradigm."
