This is a Cakefile for automatically compiling jade templates to html files in an arbitrarily deep directory tree. It was intended for use with meteor, however you can use it with any framework by changing the start task and the DIR. NOTE: this requires that chokidar and jade be installed via npm. NOTE: this assumes that the only html files unde…
