+ * The `Collection` class, which serves as the base class for some of Lithium's data objects
+ * (`RecordSet` and `Document`) provides a way to manage data collections in a very flexible and
+ * intuitive way, using closures and SPL interfaces. The `to()` method allows a `Collection` (or
+ * subclass) to be converted to another format, such as an array. The `Collection` class also allows
+ * other classes to be connected as handlers to convert `Collection` objects to other formats.
+ *
+ * The following connects the `Media` class as a format handler, which allows `Collection`s to be
+ * exported to any format with a handler provided by `Media`, i.e. JSON. This enables things like
+ * the following:
+ * {{{
+ * $posts = Post::find('all');
+ * return $posts->to('json');
+ * }}}

+/**
+ * This filter is a convenience method which allows you to automatically route requests for static
+ * assets stored within active plugins. For example, given a JavaScript file `bar.js` inside the
+ * `li3_foo` plugin installed in an application, requests to `http://app/path/li3_foo/js/bar.js`
+ * will be routed to `/path/to/app/libraries/plugins/li3_foo/webroot/js/bar.js` on the filesystem.
+ * In production, it is recommended that you disable this filter in favor of symlinking each
+ * plugin's `webroot` directory into your main application's `webroot` directory, or adding routing
+ * rules in your web server's configuration.
