The lite2 tree is in pretty good shape. The only problem with it at the moment is that it badly needs a merge with -current (and someone with the time to fix it after the merge) and it *really* badly needs someone other than me and Jeffrey to run it. I don't know about Jeffrey but I have virtually no time to spend on FreeBSD at the moment due to other commitments and lite2 is suffering as a result. -- Doug Rabson, Microsoft RenderMorphics Ltd.
