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) _makePackagesrrr)rresults r _installr(3s(DF$(KKvr ci}t|jD]\}}|Mt|tr7t |}|j j t||||||<O|||<Ut|tr\t |jdz|z}|j j t||||||jdz|z<|||<|||<|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.
