Friends:
Is David Parks' presentation package --from his fantastic web page-- usable in v.7?

Hmm. That organizational structure is different than what I'm using. I guess
I need to comprehend the box structure of mathematica... for example
"BoxData" doesn't seem to be a  documented primitive (It is referenced
inside the Cell[] documentation as a one-liner).
Is there a how-to or otherwise some documentation that describes when to use
BoxData vs. ToBoxes vs. whatever or is it one of those "It depends and it's
complicated" things?
