[Zope] File management using Zope's API

I'd like to manage (create, modify, ...) Zope File objects using Zope API in Python External Methods. The only thing I have found is the API reference but unfortunately I still don't know anything about how to use Zope API... Could someone tell me where I could find tutorials or guides to learn how to use Zope's API ? thanks ____________________________________________________________________ - http://www.WebMailSPro.com - >> VOTRE service d'email sans pub avec VOTRE nom de domaine
