Starting out with Sam’s tarify.cgi and Joe Gregorio’s sparklines as working examples I have managed to create a simple Python-script for generating an Atom feed: bzr-feed. You can of course subscribe to the changes!

Excellent! I've added a feed for 1812 using bzr-feed.

I love the fact that you can subscribe to the changes in bzr-feed because the project itself is in bzr and uses bzr-feed. This is like the YouTube video showing you how to embed YouTube videos in WikiCalc. They're both cases of what I call self-referential-integrity.
