-    .. method:: load_module(fullname)
-
-        A legacy method for loading a module.  If the module cannot be
-        loaded, :exc:`ImportError` is raised, otherwise the loaded module is
-        returned.
-
-        If the requested module already exists in :data:`sys.modules`, that
-        module should be used and reloaded.
-        Otherwise the loader should create a new module and insert it into
-        :data:`sys.modules` before any loading begins, to prevent recursion
-        from the import.  If the loader inserted a module and the load fails, it
-        must be removed by the loader from :data:`sys.modules`; modules already
-        in :data:`sys.modules` before the loader began execution should be left
-        alone.
-
-        The loader should set several attributes on the module
-        (note that some of these attributes can change when a module is
-        reloaded):
-
-        - :attr:`module.__name__`
-        - :attr:`module.__file__`
-        - :attr:`module.__cached__` *(deprecated)*

-        - :attr:`module.__package__` *(deprecated)*
-        - :attr:`module.__loader__` *(deprecated)*

-        functionality is provided.

-           The recommended API for loading a module is :meth:`exec_module`
-           (and :meth:`create_module`).  Loaders should implement it instead of
-           :meth:`load_module`.  The import machinery takes care of all the
-           other responsibilities of :meth:`load_module` when
-           :meth:`exec_module` is implemented.
