csslike is a CSS preprocessor designed to follow the latest www-style proposals from Tab Atkins for CSS variables, mixins, and nested rules (a lot of which appears to be based on LESS and SASS' curly brace syntax, but with some differences).
It's a work in progress. I wanted to make sure the lexer was extremely robust for forward compatibility, in case there are anymore additions. So, the lexer is pretty verbose, it wasn't built for speed, but it will tokenize anything, nothing is hardcoded.
It also includes some small features like auto-base64'ing images, pretty printing, minifying, as well as imported stylesheets, but for the most part, I want to keep it in line with potential standards.
