I've been meaning to jump into the wonderful world of CSS meta-languages, but I was turned off by their propensity to be in ruby (into which I don't particularly want to jump); then I found CleverCSS.

Diving into the code I was a little put off by the 1600+ line(!) monolithic approach — fortunately, it's hosted on github and open source :) so I forked it, split it into (primarily) seven different files, and generally reorganized it.

Other than that, I didn't really do much, but now that it's in a more digestible format, I expect to do some more hacking away in the future.

here's my fork of the repo.
