+/**
+ * TActiveClientScript class
+ *
+ * This is the active counterpart of the {@link TClientScript} class.
+ *
+ * TActiveClientScript has the ability to render itself on ajax
+ * callbacks. This means that every variable or function declared in javascript
+ * code will be available to the page.
+ *
+ * Beware that when rendered on normal (postback) or ajax callbacks, some
+ * javascript code won't behave in the same way.
+ * When rendered as part of a normal/postback response, scripts will execute instantly
+ * where they are in the page and in a synchronous fashion.
+ * Instead, when they are rendered as part of a callback response,
+ * they will be executed when all DOM modifications are complete and any dynamic
+ * script file includes are loaded, out-of-band and practically all blocks at once,
+ * regardless of where they actually occour in the original template/markup code.
+ * This can potentially hurt compatibility and graceful fallback.
+ *
