So while working on my first Meteor app I decided I wanted to make use of the CSSgram library, did a quick search of atmosphere packages to find it wasn’t already repackaged and figured I’d do it myself. You can check it out at https://atmospherejs.com/toadbomb/cssgram.
It’s packaged in much the same way that francocatena:compass is (see https://atmospherejs.com/francocatena/compass), in that I pretty much just made all the scss files easily available after you add the package. The rest is easy.
Let me know if you find it useful or if you have any suggestions. Cheers!
