pixelrake.com (this site) was developed as a front-end experiment w/ a Static Site Generator using the tools and setup below:
Out of the box roots comes with a mix of jade for templating, stylus for css pre-processing and the axis library. I removed some of these defaults in favor of a jade, skeleton, and sass combo. Stylus did seem tempting but i preffered to work with sass for now.
The development team for roots.cx has moved on to Spike which uses Webpack for the heavy lift. I've used Webpack a few times before and it continues to make gains as the Swiss Army Knife of module packagers. Roots.cx felt a bit more straight forward and certainly met my needs -- I'll have to consider Spike and Webpack for another project.
