Compared templating engines: - [Handlebars](http://www.handlebarsjs.com/) - [Resig Micro-Templating (modified)](http://ejohn.org/blog/javascript-micro-templating/) - [Underscore JS](http://documentcloud.github.com/underscore/) - [doT.js](https://github.com/olado/doT) - [dust.js](https://raw.github.com/akdubya/dustjs/master/dist/dust-full-0.3.0.js) - [EJS](http://embeddedjs.com/) Are you a spammer?
