deprecated CSS compiler - use sassc or ruby-sassc instead

 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.
 .
 Ruby Sass should no longer be used and will no longer be receiving any
 active development. Please use sassc or ruby-sassc instead.
