Empower your website frontends with layouts, meta-data, pre-processors (markdown, jade, coffeescript, etc.), partials, skeletons, file watching, querying, and an amazing plugin system. Use it either standalone, as a build script, or even as a module in a bigger system. Either way, DocPad will streamline your web development process allowing you to craft full-featured websites quicker than ever before.
