[Zope] Editing DTML Methods with Emacs ?

I remember this problem was raised here once, but I don't know if there's a solution now: I'd like to use something else than Netscape's text widget to edit my Zope site. XEmacs would be preferred. Ftp access to the site does work with the /superuser@host#8021:/ syntax. The problem is that if I edit and save a DTML method with XEmacs, the method turns into a DTML document, breaking the logic of the site. I think I understood the underlying problem (ftp just can't express the differences between the objects), but I don't remember if there was any workaround. So what do people use to prototype Zope sites ? Are you all stuck with the Zope web management interface ? Gregor
