According to the sfwnv folks - http://www.opensolaris.org/jive/thread.jspa?threadID=34173&tstart=0 - the sfw repository contains only the .tar.gz files and the associated Makefiles, patches etc. The .tar.gz is expanded only for delivery to the OpenGrok indexer and these sources aren't actually checked into the repository in the expanded form. Pretty nifty.
