-/**
- * TFeedService class
- *
- * TFeedService provides to end-users feed content.
- *
- * TFeedService manages a set of feeds. The service parameter, referring
- * to the ID of the feed, specifies which feed content to be provided to end-users.
- *
- * To use TFeedService, configure it in application configuration as follows,
- * <code>
- *  <service id="feed" class="System.Web.Services.TFeedService">
- *    <feed id="ch1" class="Path.To.FeedClass1" .../>
- *    <feed id="ch2" class="Path.To.FeedClass2" .../>
- *    <feed id="ch3" class="Path.To.FeedClass3" .../>
- *  </service>
- * </code>
- * where each &lt;feed&gt; element specifies a feed identified by its "id" value (case-sensitive).
- *
- * PHP configuration style:
- * <code>
- * array(
- *   'feed' => array(
- *	   'ch1' => array(
- *       'class' => 'Path.To.FeedClass1',
- *       'properties' => array(
- *          ...
- *        ),
- *   ),
- * )
- * </code>
- *
- * The class attribute indicates which PHP class will provide the actual feed
- * content. Note, the class must implement {@link IFeedContentProvider} interface.
- * Other initial properties for the feed class may also be specified in the
- * corresponding &lt;feed&gt; element.
- *
- * To retrieve the feed content identified by "ch2", use the URL
- * <code>/path/to/index.php?feed=ch2</code>

-/**
- * TPageService class.
- *
- * TPageService implements the service for serving user page requests.
- *
- * Pages that are available to client users are stored under a directory specified by
- * {@link setBasePath BasePath}. The directory may contain subdirectories.
- * Pages serving for a similar goal are usually placed under the same directory.
- * A directory may contain a configuration file <b>config.xml</b> whose content
- * is similar to that of application configuration file.
- *
- * A page is requested via page path, which is a dot-connected directory names
- * appended by the page name. Assume '<BasePath>/Users/Admin' is the directory
- * containing the page 'Update'. Then the page can be requested via 'Users.Admin.Update'.
- * By default, the {@link setBasePath BasePath} of the page service is the "pages"
- * directory under the application base path. You may change this default
- * by setting {@link setBasePath BasePath} with a different path you prefer.
- *
- * 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
- * directory's configuration, if both configurations refer to the same module.
- *
- * By default, TPageService will automatically load two modules:
- * - {@link TTemplateManager} : manages page and control templates
- * - {@link TThemeManager} : manages themes used in a Prado application
- *
- * In page directory configurations, static authorization rules can also be specified,
- * which governs who and which roles can access particular pages.
- * Refer to {@link TAuthorizationRule} for more details about authorization rules.
- * Page authorization rules can be configured within an <authorization> tag in
- * each page directory configuration as follows,
- * <authorization>
- *   <deny pages="Update" users="?" />
- *   <allow pages="Admin" roles="administrator" />
- *   <deny pages="Admin" users="*" />
- * </authorization>
- * where the 'pages' attribute may be filled with a sequence of comma-separated
- * page IDs. If 'pages' attribute does not appear in a rule, the rule will be
- * applied to all pages in this directory and all subdirectories (recursively).
- * Application of authorization rules are in a bottom-up fashion, starting from
- * the directory containing the requested page up to all parent directories.
- * The first matching rule will be used. The last rule always allows all users
- * accessing to any resources.

+/**
+ * TPageService class.
+ *
+ * TPageService implements the service for serving user page requests.
+ *
+ * Pages that are available to client users are stored under a directory specified by
+ * {@link setBasePath BasePath}. The directory may contain subdirectories.
+ * Pages serving for a similar goal are usually placed under the same directory.
+ * A directory may contain a configuration file <b>config.xml</b> whose content
+ * is similar to that of application configuration file.
+ *
+ * A page is requested via page path, which is a dot-connected directory names
+ * appended by the page name. Assume '<BasePath>/Users/Admin' is the directory
+ * containing the page 'Update'. Then the page can be requested via 'Users.Admin.Update'.
+ * By default, the {@link setBasePath BasePath} of the page service is the "pages"
+ * directory under the application base path. You may change this default
+ * by setting {@link setBasePath BasePath} with a different path you prefer.
+ *
+ * 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
+ * directory's configuration, if both configurations refer to the same module.
+ *
+ * By default, TPageService will automatically load two modules:
+ * - {@link TTemplateManager} : manages page and control templates
+ * - {@link TThemeManager} : manages themes used in a Prado application
+ *
+ * In page directory configurations, static authorization rules can also be specified,
+ * which governs who and which roles can access particular pages.
+ * Refer to {@link TAuthorizationRule} for more details about authorization rules.
+ * Page authorization rules can be configured within an <authorization> tag in
+ * each page directory configuration as follows,
+ * <authorization>
+ *   <deny pages="Update" users="?" />
+ *   <allow pages="Admin" roles="administrator" />
+ *   <deny pages="Admin" users="*" />
+ * </authorization>
+ * where the 'pages' attribute may be filled with a sequence of comma-separated
+ * page IDs. If 'pages' attribute does not appear in a rule, the rule will be
+ * applied to all pages in this directory and all subdirectories (recursively).
+ * Application of authorization rules are in a bottom-up fashion, starting from
+ * the directory containing the requested page up to all parent directories.
+ * The first matching rule will be used. The last rule always allows all users
+ * accessing to any resources.
