It looks mainly to be pitched as an alternative to Grunt, the current main (I think?) Node.js build tool. And its primary feature seems to be that you don't have to figure out where your intermediate build products go. Beyond that, who knows.

(Grunt, incidentally, strikes me as a system that has learned nothing at all from decades of other build tools. It's about one step better than piping globs to unix commands.)
