[Zope] Alternative management interface

Even more urgent: (almost cry for help :-( ) Please, could anybody give me a piece of advice on the topic: I need to create an alternative management interface for my Site in order my site administrators to be able to manage the site in a special way. Where should I place all my administrative .py modules & dtml docs in order for them to work the same way as native Zope management tools ? Thanks in advance for my salvation, Anton.
