What is Alabaster?
Alabaster is a visually (c)lean, responsive, configurable theme for the Sphinx documentation system. It is Python 2+3 compatible.
It began as a third-party theme, and is still maintained separately, but as of Sphinx 1.3, Alabaster is an install-time dependency of Sphinx and is selected as the default theme.
You can install the development version via
pip install -e git+https://github.com/bitprophet/alabaster/#egg=alabaster.
