This gem is based on Rails plugin 'css_dryer': http://github.com/airblade/css_dryer. Unlike 'css_dryer', this one doesn't create any controllers and views. Instead, it acts more like SASS, but uses css_dryer parser (which allows you to use completely conventional css-syntax and write one-line css rules). * Read 'install' section to find out how to use it with Rails or any other Ruby appplication. * Read USAGE.markdown file to learn about css_dryer parser (copypasted from css_dryer README).
