How pretty is rst2pdf's output? Take a look.
I am a big Alexandre Dumas fan. He's the direct ancestor of Neal Stephenson, so many of you should like him too. So I used one of his best books to try some automatic typesetting of project gutenberg texts.

Here's a far look of the first two pages:

Yes, the typesetting is not really LaTeX quality, but it's not bad, either.
Compare it with the HTML version at project Gutenberg. The typesetting is a thing of beauty compared to that :-(
