[log5-devel] can't follow the tutorial - log5-devel@common-lisp.net - mailman3.common-lisp.net

2 Feb 2007


      I noticed the log5 tutorial was up so I decided to play around a bit.
Can anyone explain what the problem is in the session below? It
appears I'm simply entering things in almost verbatim from the
tutorial yet it isn't working. Am I just dense?
