+ *     app.engine('jade', require('jade').__express);
+ *
+ * For engines that do not provide `.__express` out of the box,

+ * you may use this method. For example mapping the EJS template engine to
+ * ".html" files:
+ *
+ *     app.engine('html', require('ejs').renderFile);
+ *
+ * In this case EJS provides a `.renderFile()` method with
+ * the same signature that Express expects: `(path, options, callback)`,
+ * though note that it aliases this method as `ejs.__express` internally
+ * so if you're using ".ejs" extensions you dont need to do anything.
+ *
+ * Some template engines do not follow this convention, the
+ * [Consolidate.js](https://github.com/visionmedia/consolidate.js)
+ * library was created to map all of node's popular template
+ * engines to follow this convention, thus allowing them to
