+</span> * Ext.Direct aims to streamline communication between the client and server by providing a single interface that
+ * reduces the amount of common code typically required to validate data and handle returned data packets (reading data,
+ * error conditions, etc).
+ *
+ * The Ext.direct namespace includes several classes for a closer integration with the server-side. The Ext.data
+ * namespace also includes classes for working with Ext.data.Stores which are backed by data from an Ext.Direct method.
+ *
+ * # Specification
+ *
+ * For additional information consult the [Ext.Direct Specification][1].
+ *
+ * # Providers
+ *
+ * Ext.Direct uses a provider architecture, where one or more providers are used to transport data to and from the
+ * server. There are several providers that exist in the core at the moment:
+ *
+ * - {@link Ext.direct.JsonProvider JsonProvider} for simple JSON operations
+ * - {@link Ext.direct.PollingProvider PollingProvider} for repeated requests
+ * - {@link Ext.direct.RemotingProvider RemotingProvider} exposes server side on the client.
+ *
+ * A provider does not need to be invoked directly, providers are added via {@link Ext.direct.Manager}.{@link #addProvider}.
+ *
+ * # Router
+ *
+ * Ext.Direct utilizes a "router" on the server to direct requests from the client to the appropriate server-side
+ * method. Because the Ext.Direct API is completely platform-agnostic, you could completely swap out a Java based server
+ * solution and replace it with one that uses C# without changing the client side JavaScript at all.
+ *
+ * # Server side events
+ *
+ * Custom events from the server may be handled by the client by adding listeners, for example:
+ *
+ * {"type":"event","name":"message","data":"Successfully polled at: 11:19:30 am"}
+ *
+ * // add a handler for a 'message' event sent by the server
+ * Ext.direct.Manager.on('message', function(e){
+ * out.append(String.format('<p><i>{0}</i></p>', e.data));
+ * out.el.scrollTo('t', 100000, true);
+ * });
