[logback-user] Minimal library dependency for logback implementation of RequestLogImpl

To implement the Jetty RequestLog in Jetty, http://logback.qos.ch/access.html#jetty what is the minimal set lof slf4j and log libraries I need? slf4j-? logback-core-VERSION.jar logback-access-VERSION.jar

From the above doc, I see the two logback-core and logback-access libraries are minimally necessary to use ch.qos.logback.access.jetty.RequestLogImpl What minimal set of slf4j libraries are necessary?
