Hi Jon, Sfl4j is only an API for logging. The default back end for sfl4j is logback (http://logback.qos.ch/). But it offers a way to be used with old java logging libraries, such as log4j and common-logging, that's what you saw on the web site.
There is no Layouts in slf4j, but logback offers the same functionalities as log4j such as layouts (http://logback.qos.ch/manual/layouts.html). If you think the migration is a good idea, maybe I could do it.
