Greetings everybody, I've tried to find some information on this subject by using Google, with no success. Therefore I ask it here, and if I've selected the wrong mailing list please let me know and accept my appologies. I need to develop a Zope product whose logic-part is to be left untouched but whose presentation parts (DTML methods, etc.) should be customizable. I'll give a little example to clearify: Let's say I write a guestbook product. This product has a default user interface which means that I can, if I wish, just add a guestbook product to the customer's folder and that's it. Unfortunately we're seldom that lycky. Perhaps the customer wants the guestbook in another language, or "embedded" into his/her original website. To do this I'll have to override the default presentation pages somehow. The management screens can stay as they were. What is the best approach?
