To build the OpenLayers documentation:

• Install Python. (If you're on a mac or on Linux, you probably already have it installed. For Windows,  http://www.python.org/download/)
• Install setuptools. ( http://pypi.python.org/pypi/setuptools has instructions)
• Install sphinx via easy_install:

 $ easy_install Sphinx

or

  C:\Python\scripts\easy_install.exe Sphinx

Then, check out the OpenLayers docs:

 $ svn co http://svn.openlayers.org/trunk/doc/
 $ cd doc
 $ sphinx-build -b html . html

Then you can do the last command only to rebuild the documentation.
