[Zope] Export multiple objects at once?

I'm trying to abandon an instance of Zope for a newer one but I have objects (ZWiki pages and such) that I want to export and import into the new instance. How do I export more than one object from an instance at one time? -- Regards, Bryan Simmons -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Always code as if the guy who ends up maintaining your code will be a violent psychopath who knows where you live. -- Rick Osborne -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
