[Zope] Hiding header?

Is it possible to hide the header that Zope advertises? Currently, Zope is advertising "Server: Zope/(Zope 2.7.3-0, python 2.3.4, linux2) ZServer/1.1 Plone/2.0.5", that is forwarded as is by Apache. I know that apache can be set to hide its current version. It would be nice if we could do the same with Zope. Is this possible? Where/how do we do it? Shane
