Rivets - Python asset management system

Rivets is a port of Sprockets from Ruby to Python. It will let you split up your JS and CSS files into sensible, manageable chunks and, by specifiying any requirements in the file, concatenate them into a single file to serve to the browser. It will also let you write your code in either SCSS or CoffeeScript and it will compile them on the fly.

It can also handle caching of assets and can be used as a cherrypy compatible route dispatcher.
