Consider these example:: a = {"foo": "bar"} b = {"twisted": {"__version__": "42.6"}} c = {"twisted": {"plugin": {"getPlugins": stub}}} C{_install(a)} will place an item into C{sys.modules} with C{"foo"} as the key and C{"bar" as the value. C{_install(b)} will place an item into C{sys.modules} with C{"twisted"} as the key. The value will be a new module object. The module will have a C{"__version__"} attribute with C{"42.6"} as the value. C{_install(c)} will place an item into C{sys.modules} with C{"twisted"} as the key. The value will be a new module object with a C{"plugin"} attribute. An item will also be placed into C{sys.modules} with the key C{"twisted.plugin"} which refers to that module object. That module will have an attribute C{"getPlugins"} with a value of C{stub}. @param modules: A mapping from names to definitions of modules. The names are native strings like C{"twisted"} or C{"unittest"}. Values may be arbitrary objects. Any value which is not a dictionary will be added to C{sys.modules} unmodified. Any dictionary value indicates the value is a new module and its items define the attributes of that module. The definition of this structure is recursive, so a value in the dictionary may be a dictionary to trigger another level of processing. @return: L{None} N)� _makePackagesr r r )r �resultr r r �_install= s " r& c C s� i }t |�� �D ]�\}}| dkrZt|t�rPt|�}|j�t|||�� |||< q�|||< qt|t�r�t| jd | �}|j�t|||�� ||| jd | < |||< q|||< q|S )a� Construct module objects (for either modules or packages). @param parent: L{None} or a module object which is the Python package containing all of the modules being created by this function call. Its name will be prepended to the name of all created modules. @param attributes: A mapping giving the attributes of the particular module object this call is creating. @param result: A mapping which is populated with all created module names. This is suitable for use in updating C{sys.modules}. @return: A mapping of all of the attributes created by this call. This is suitable for populating the dictionary of C{parent}. @see: L{_install}.
