-/**
- * CThemeManager manages the themes for the Web application.
- *
- * A theme is a collection of view/layout files and resource files
- * (e.g. css, image, js files). When a theme is active, {@link CController}
- * will look for the specified view/layout under the theme folder first.
- * The corresponding view/layout files will be used if the theme provides them.
- * Otherwise, the default view/layout files will be used.
- *
- * By default, each theme is organized as a directory whose name is the theme name.
- * All themes are located under the "WebRootPath/themes" directory.
- *
- * To activate a theme, set the {@link CWebApplication::setTheme theme} property
- * to be the name of that theme.
- *
- * Since a self-contained theme often contains resource files that are made
- * Web accessible, please make sure the view/layout files are protected from Web access.
- *
- * @property array $themeNames List of available theme names.
- * @property string $basePath The base path for all themes. Defaults to "WebRootPath/themes".
- * @property string $baseUrl The base URL for all themes. Defaults to "/WebRoot/themes".
