+/**
+ * TClientScript class
+ *
+ * Allows importing of Prado Client Scripts from template via the
+ * {@link setPradoScripts PradoScripts} property. Multiple Prado
+ * client-scripts can be specified using comma delimited string of the
+ * javascript library to include on the page. For example,
+ *
+ * <code>
+ * <com:TClientScript PradoScripts="effects, rico" />
+ * </code>
+ *
+ * Custom javascript files can be register using the {@link setScriptUrl ScriptUrl}
+ * property.
+ * <code>
+ * <com:TClientScript ScriptUrl=<%~ test.js %> />
+ * </code>
+ *
+ * Contents within TClientScript will be treated as javascript code and will be
+ * rendered in place.
+ *
+ * Since Prado 3.2 the property {@link setFlushScriptFiles FlushScriptFiles} controls
+ * whether Prado will flush the script files defined in the page before rendering the
+ * TClientScript contents.
+ * If you're not using any external functions in your TClientScript block, you should
+ * set the {@link setFlushScriptFiles FlushScriptFiles} property to false, so Prado
+ * can postpone the loading of all the referenced script files further down the page
+ * generation cycle.
+ *
