Echo JS 0.11.0

6 months later: "Why I left Gulp, Grunt and npm Scripts for 'new hot thing'"

npm scripts have been there from the start.  I've been using them as my primary entry for some while.  Even with grunt/gulp, as you can simply use the version defined in package.json with a project instead of relying on a global, potentially incompatible version.

Beyond this, in general, it's just easier to work with.  If you need more, a ./scripts/ directory with one or more scripts started via npm that use shelljs works very well.
