[Zope] Syntax checker for Zope

Is there a syntax checking module for Zope, a program that can be used to help find those bugs that generate inscrutable error messages and not a hint as to where the real problem lies? Every so ofen I have a Zope object that's in error--a misplaced quote, an extra or missing bit of markup (dtml or html)--but finding it is a lengthy and frustrating process. A tool would be helpful. I've ggogled about looking but have not found anything. Pointers?
