-/**
- * TThemeManager class
- *
- * TThemeManager manages the themes used in a Prado application.
- *
- * Themes are stored under the directory specified by the
- * {@link setBasePath BasePath} property. The themes can be accessed
- * via URL {@link setBaseUrl BaseUrl}. Each theme is represented by a subdirectory
- * and all the files under that directory. The name of a theme is the name
- * of the corresponding subdirectory.
- * By default, the base path of all themes is a directory named "themes"
- * under the directory containing the application entry script.
- * To get a theme (normally you do not need to), call {@link getTheme}.
- *
- * TThemeManager may be configured within page service tag in application
- * configuration file as follows,
- *
- * where {@link getCacheExpire CacheExpire}, {@link getCacheControl CacheControl}
- * and {@link getBufferOutput BufferOutput} are configurable properties of THttpResponse.
