I wrote one when i was at school, probably 1997 or 1998, to help a friend build a fan site for the Longpigs [1]. I assumed it was long lost, but apparently he took it to university with him, and the web archive caught it:

http://web.archive.org/web/20010519223318/http://users.ox.ac...

I think all the content was in handwritten HTML, but the generator knew enough to be able to do the navigation links and sitemap and so on.
