# This script compiles all the documentation.
#
# Required software:
#
# 1) Sphinx documentation builder (python-sphinx package on Debian/Ubuntu)
#
# 2) pdflatex, which means the following Debian/Ubuntu packages:
#    * texlive-latex-base
#    * texlive-latex-recommended
#    * texlive-latex-extra
#    * texlive-fonts-recommended
#
# All these TeX packages together are close to a gig :-| But after you've
# installed them, you can remove texlive-latex-extra-doc to save 400MB.
