Ruby Sass middleware for Metalsmith.
This middleware was created to overcome some limitations in libsass (which node-sass is built on, which metalsmith-sass uses). While libsass is an excellent tool for the node community, this issue unfortunately can be a dealbreaker for some until it is resolved.
This project claims no credit for originality. Most of the code comes from @steveschobert's excellent metalsmith-sass project. Also, some of the code calling out to Ruby Sass came from the grunt-contrib-sass project, which also uses Ruby Sass. Big thanks to both projects!
