      sphinx.ext.autosummary
      ~~~~~~~~~~~~~~~~~~~~~~
  
      Sphinx extension that adds an autosummary:: directive, which can be
      used to generate function/method/attribute/etc. summary lists, similar
      to those output eg. by Epydoc and other API doc generation tools.
  
      An :autolink: role is also provided.
  
      autosummary directive
      ---------------------
  
      The autosummary directive has the form::
  
          .. autosummary::
             :nosignatures:
             :toctree: generated/
  
             module.function_1
             module.function_2
             ...
  
      and it generates an output table (containing signatures, optionally)
  
          ========================  =============================================
          module.function_1(args)   Summary line from the docstring of function_1
          module.function_2(args)   Summary line from the docstring
          ...
          ========================  =============================================
  
      If the :toctree: option is specified, files matching the function names
      are inserted to the toctree with the given prefix:
  
          generated/module.function_1
          generated/module.function_2
          ...
  
      Note: The file names contain the module:: or currentmodule:: prefixes.
  
      .. seealso:: autosummary_generate.py
  
  
      autolink role
      -------------
  
      The autolink role functions as ``:obj:`` when the name referred can be
      resolved to a Python object, and otherwise it becomes simple emphasis.
      This can be used as the default role to make links 'smart'.
