API dump in RST files
---------------------
  Run this script from blenders root path once you have compiled blender

    ./blender.bin -b -noaudio -P doc/python_api/sphinx_doc_gen.py

  This will generate python files in doc/python_api/sphinx-in/
  providing ./blender.bin is or links to the blender executable

  To choose sphinx-in directory:
    ./blender.bin -b -P doc/python_api/sphinx_doc_gen.py -- -o ../python_api

  For quick builds:
    ./blender.bin -b -P doc/python_api/sphinx_doc_gen.py -- -q

Sphinx: HTML generation
-----------------------
  After you have built doc/python_api/sphinx-in (see above),
  generate html docs by running:

    cd doc/python_api
    sphinx-build sphinx-in sphinx-out

  This requires sphinx 1.0.7 to be installed.

Sphinx: PDF generation
----------------------
  After you have built doc/python_api/sphinx-in (see above),
  generate the pdf doc by running:

    sphinx-build -b latex doc/python_api/sphinx-in doc/python_api/sphinx-out
    cd doc/python_api/sphinx-out
    make
