[Zope] A Newbie question

Hi, I have seen on the howtos how to let apache serve static pages, but I still haven't seen an answer to the following question: Suppose I already have a big site that uses perl/cshell. Now suppose I want to move to Zope but without loosing any of that site or even converting. What would the best solution be? Example: www.foo.bar is a huge site. I want to move to Zope but wish to keep the site as is, only add zope objects with time. In other words, 90% of the site will stay static as is for a long time. How would you start this thing?
