environment.

If you're desiring to build PDF outputs, it is recommended to use version 1.4.6 or upper. +Most distributions are shipped with Sphinx, but its toolchain is fragile, +and it is not uncommon that upgrading it or some other Python packages +on your machine would cause the documentation build to break. + +A way to get rid of that is to use a different version than the one shipped +on your distributions. In order to do that, it is recommended to install +Sphinx inside a virtual environment, using ``virtualenv-3`` +or ``virtualenv``, depending on how your distribution packaged Python 3. + +.. note:: + + #) Sphinx versions below 1.5 don't work properly with Python's + docutils version 0.13.1 or upper.
