"""
Python script for building documentation.

To build the docs you must have all optional dependencies for pandas
installed. See the installation instructions for a list of these.

<del>Note: currently latex builds do not work because of table formats that are not
supported in the latex generation.</del>

2014-01-30: Latex has some issues but 'latex_forced' works ok for 0.13.0-400 or so

Usage
-----
python make.py clean
python make.py html
