[Zope] Translating a webpage

I'm wondering if someone can point me in the direction of some documentation that will tell me the best way to translate a web page into multiple languages using Zope Page Templates. In previous sites we've done in DTML we used a 'phrases' table in our MySQL database that contained phrases in each language the site required. We then used sql methods and a dtml-let statement to create a list of the phrases used on a certain page. I'm considering using the same basic idea for a page template site, but am wondering if there is a better way of doing translations. I've read about using .po files. Is there an easy way to hook these up to Zope? Any help would be greatly appreciated. Thanks.
