I just started looking at Sphinx, and I'd remembered a bit of discussion about the license CMU used. I did a mailing list search on "sphinx" just now back the past 4 quarters of the archive, and the only thing that turned up was that section 4 of the license passed the Open Source guidelines but wasn't sure if it passed the Debian guidelines. Anyway, I was looking over the license and it looks to me that section 5 is a ringer for the BSD "advertising" clause.
Do section 4 or 5 place Sphinx into non-free? I'm pretty sure 5 does but I'd like it confirmed.
