[Zope] Lack of docs:How to delete user from Python script ?

Greetings, respective sages ! Only you, who has been living for centuries, are able to solve the problem: I can successfully add user to acl_user folder by means of commands: ......... req=context.REQUEST .......... userFolder.manage_users('Add', req, req.RESPONSE) I don't say it's the clearest way, but at least it works... Would anybody be so kind to suggest how to remove that user (I'd prefer working variant) Thanx a big big bunch :-) Anton
