[Zope] add local filesystem directory with python

Hi, How can I add a local filesystem directory with a python script ? With a DTML-method or pythonscript I receive the following traceback. Traceback (innermost last): Module ZPublisher.Publish, line 98, in publish Module ZPublisher.mapply, line 88, in mapply Module ZPublisher.Publish, line 39, in call_object Module Shared.DC.Scripts.Bindings, line 252, in __call__ Module Shared.DC.Scripts.Bindings, line 283, in _bindAndExec Module Products.PythonScripts.PythonScript, line 315, in _exec Module Script (Python), line 1, in crtLFS - <PythonScript at /Maintenance/Smartstorage/crtLFS> - Line 1 AttributeError: manage_addLocalFS What is wrong ?
