  * Pages that are available to client users are stored under a directory specified by
  * {@link setBasePath BasePath}. The directory may contain subdirectories.
  * A directory may be used to group together the pages serving for the similar goal.
- * Each directory must contain a configuration file <b>config.xml</b> that is similar to the application
- * configuration file. The only difference is that the page directory configuration
- * contains a mapping between page IDs and page types. The page IDs are visible
- * by client users while page types are used on the server side.

  * A page is requested via page path, which is a dot-connected directory names
- * appended by the page ID. Assume '<BasePath>/Users/Admin' is the directory
- * containing the page 'Update' whose type is UpdateUserPage. Then the page can

+ * Page name refers to the file name (without extension) of the page template.
+ * In order to differentiate from the common control template files, the extension
+ * name of the page template files must be '.page'. If there is a PHP file with
+ * the same page name under the same directory as the template file, that file
+ * will be considered as the page class file and the file name is the page class name.
+ * If such a file is not found, the page class is assumed as {@link TPage}.
  *
  * Modules can be configured and loaded in page directory configurations.
  * Configuration of a module in a subdirectory will overwrite its parent
