[Zope] Syntax checker for Zope

[Dennis Allison]

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?
