What about starting from this rather than individual pages in a tree?

It could work, assuming no horrible gotchas in the formatting on that page, but the parser's already written, and since the app as written includes a ham-fisted cache, I didn't notice any performance issues after the initial download =)

If I find some spare time, I'll take a look at it. Thanks!

There are a few formatting irregularities there, but I have some groovy code parsing it currently.
