CSS Crush is an extensible PHP-based CSS pre-processor that minimizes many of the hacks and workarounds used in CSS development. Here are some uses of it:

It can scan the @import directives and includes the contents of them to the output HTML generated in order not to make multiple requests.

There is no need to use any browser-specific properties, rules or functions as CSS Crush can create them automatically according to the browser used.

Some built-in math functions and ability to use variables help getting the most out of CSS.

And, there is support for minification and caching for serving them as fast as possible.
