SCSS and stylesheets in 1.3

I’m confused about what I should be doing to support SCSS in 1.3, and also where I should be putting the SCSS files.

The official guide at still cites fourseven:scss as the best tool to use for SCSS, but on the package description itself it still says that it was built to support 1.2.

Also, I couldn’t find any mention in the docs about the best file structure for CSS. Should I create a folder named stylesheets and put it inside client?

Updated: Sashko answered my question; I still need Meteor-specific packages to extend the build tool properly; I can’t do that via NPM yet, so I’m going to continue using fourseven:scss.
