Sass makes CSS fun again. Sass is an extension of CSS3, adding nested rules, variables, mixins, selector inheritance, and more. It's translated to well-formatted, standard CSS using the command line tool or a web-framework plugin. This is a repackaged GEM in a JAR format of the sass-lang.gem package. The sass-gems package version follows the sass-lang.gem versions located http://rubyforge.org/frs/?group_id=9702. Simply change the version of this package to download and repackage the same GEM version.

There is a newer version: 3.2.9
