+ * control class name, or the template file name.
+ * The former is via calling {@link getTemplateByClassName}, which tries to
+ * locate the corresponding template file under the directory containing
+ * the class file. The name of the template file is the class name with
+ * the extension '.tpl'. To load a template from a template file path,
+ * call {@link getTemplateByFileName}.
+ *
+ * By default, TTemplateManager is registered with {@link TPageService} as the
+ * template manager module that can be accessed via {@link TPageService::getTemplateManager()}.
