== Python API docs ==

- Works in macOSX now (hackish)
(TODO: not check for OSX explicitly but handle exception if it fails)

- We can now generate rst files outside out of the source (was annoying)
- Moved some vars at module level
- Managing the command line args with argparse.
Example usage:
./cmake/bin/blender -b -P ./blender/doc/python_api/sphinx_doc_gen.py -- -o ./python_api
