Thanks for the clarification of some of the intent of CSS 2.1, sab39. I've skimmed through some of the introductory material for the draft spec, and it's pretty clear that they've learned quite a bit in the five years since the CSS 2 specification was announced.
Web photo galleries
After further inspection, gallery.py is a little too crude for my purposes, although it could probably be altered to do what I want: generate a static website that looks something like Gallery. I'd use Gallery, but it does far more than necessary; I just want something that will generate a nicely-indexed, navigable set of webpages, based on a set of images and a few descriptions. I'll probably whack away at the Python version first before plodding off on my own.
