  # Astropy documentation build configuration file.
  #
  # This file is execfile()d with the current directory set to its containing dir.
  #
  # Note that not all possible configuration values are present in this file.
  #
  # All configuration values have a default. Some values are defined in
  # the global Astropy configuration which is loaded here before anything else.
  # See astropy.sphinx.conf for which values are set there.
  
  # If extensions (or modules to document with autodoc) are in another directory,
  # add these directories to sys.path here. If the directory is relative to the
  # documentation root, use os.path.abspath to make it absolute, like shown here.
  # sys.path.insert(0, os.path.abspath('..'))
  # IMPORTANT: the above commented section was generated by sphinx-quickstart, but
  # is *NOT* appropriate for astropy or Astropy affiliated packages. It is left
  # commented out with this explanation to make it clear why this should not be
  # done. If the sys.path entry above is added, when the astropy.sphinx.conf
  # import occurs, it will import the *source* version of astropy instead of the
  # version installed (if invoked as "make html" or directly with sphinx), or the
  # version in the build directory (if "python setup.py build_sphinx" is used).
  # Thus, any C-extensions that are needed to build the documentation will *not*
  # be accessible, and the documentation will not build correctly.
