blender/doc/python_api/sphinx_doc_gen.py
Campbell Barton b6631b8be7 fixes for python api docs. 
also move foreach_get/set examples into their own py example files (prefer not to have example code built into blenders binary).

SCRIPT_HELP_MSG = """
API dump in RST files
---------------------
Run this script from blenders root path once you have compiled blender
./blender.bin --background -noaudio --python 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 --background --python doc/python_api/sphinx_doc_gen.py -- --output ../python_api
For quick builds:
./blender.bin --background --python doc/python_api/sphinx_doc_gen.py -- --partial bmesh.*
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
