sphinx-doc.org Prerequisites section is out-of-date
"Sphinx needs at least Python 2.5 or Python 3.1 to run"
It should be at least 2.6 now. It might be good to also update the pypi entry for Sphinx to show that.
Also, on http://sphinx-doc.org/index.html
"Get Sphinx from the Python Package Index, or install it with:
easy_install -U Sphinx"
Suggest replacing with:
pip install -U sphinx
