It may be a better fit for someone else's knowledge and day-to-day usage though.
Nevermind, I should've actually looked at http://sourceforge.net/p/cygwin-ports/python-sphinx/ci/master/tree/python-sphinx.cygport first. It's using distutils instead of pip, but it looks like cygport already does all the work. I'll have a go at ITP'ing the latest version of python-sphinx myself, if all it needs is a maintainer other than Yaakov. Doesn't address the pip vs distutils issue, but that can wait. -Tony
