[Zope-dev] File System Directory Files Permission Setting

Is there a way to set zope permissions for files that are linked to zope with file system directory view. For example, i have a zope python script which must only be executed by users that have manager role. In order to do this i think i have 2 alternatives: 1- I can control the permission in the zope python script script user = getAuthenticatedUser() if(user has manager role): .... else: go to login 2- I can put a special file like .metadata file and set the python script zope permissions. (I don't know how can i do this) Thanks,
