[Zope] Is there a tool for pretty-formatting/indenting DTML code?

I've been working with Zope for a bit now and I love it. However, a few of the tools I'm used to having with other scripting tools are missing in the Zope realm.. One thing I would very much like to have is a script that could go through a long DTML document and pretty-format the code, not unlike the way I use BBEdit's formatting command on my Mac for HTML. Does such an animal exist, on any platform, or should I just try to adapt something I already have? I don't want to have to reinvent the wheel so to speak.. The big reason I need this is for indenting.. It makes the code much more readable and I have found myself spending a lot of time doing this by hand.. it just gets tedious.. Thank you..
