Convert CSS to SCSS

I’m in the (very slow) process of porting a few of my more content heavy sites from their old CMS systems across to docpad and http://node.js. One of the things i’m doing is converting all my CSS to SCSS – which i’ve previously always done by hand. However i just found this:, which allows me to paste in CSS and it will actually convert it to SCSS. This includes intelligent rule nesting – genius.
