# apt-get install python-sphinx texlive texlive-latex-extra libalgorithm-diff-perl \
                 texlive-humanities texlive-generic-recommended graphviz \

If the version of python-sphinx installed is too old, then an additional new version can be installed with the Python package installer:

$ git clone
$ export PATH=$PWD/latexdiff/:$PATH

On Mac OS X:

Install MacTeX

Install pip if you do not have it:

$ sudo easy_install pip

pip install --user --upgrade Sphinx
sudo pip install --upgrade Sphinx

If you are using brew then you can install graphviz like this:

brew install graphviz

If you are using macports then you can install graphviz like this:

$ sudo port install graphviz

Make commands:

$ make latexpdf # For generating pdf
$ make html # For generating a hierarchy of html pages
$ make singlehtml # For generating a single html page
