       object: module
 
    Modules are a basic organizational unit of Python code, and are created by
-   the :ref:`importmachinery` as invoked either by the :keyword:`import`
-   statement (see section :ref:`import`) or by calling the built in
-   :func:`__import__` function.  A module object has a namespace implemented
-   by a dictionary object (this is the dictionary referenced by the
-   ``__globals__`` attribute of functions defined in the module).  Attribute
-   references are translated to lookups in this dictionary, e.g., ``m.x`` is
-   equivalent to ``m.__dict__["x"]``. A module object does not contain the
