It's the split between template and programming thing.  I've considered
this myself... suppose you're wanting to build a form, with a great deal
of customization involved layout/graphics wise (so that none of the
form-building tools are really adequate).  Suppose further that the script
doesn't really care (much) what's in the form, because its only job is to
save the settings in a file.

I can't speak to the original poster's exact situation, but I've been
mulling over something along these lines.  Problem *I* have is that the
script really needs to know more than just the parm name... it should know
whether the end-user obeyed the form length, actually picked one of the
SELECT options or hand-built a bogus submission, things like that.

I haven't quite figured out whether I should write something that analyzes
a read-in template to produce verification code (and if so, whether it
should happen on the fly or not), use a meta-template to produce both the
verification code and HTML fragments, or what.
