-/**
- * TAssetManager class
- *
- * TAssetManager provides a scheme to allow web clients visiting
- * private files that are normally web-inaccessible.
- *
- * TAssetManager will copy the file to be published into a web-accessible
- * directory. The default base directory for storing the file is "assets", which
- * should be under the application directory. This can be changed by setting
- * the {@link setBasePath BasePath} property together with the
- * {@link setBaseUrl BaseUrl} property that refers to the URL for accessing the base path.
- *
- * By default, TAssetManager will not publish a file or directory if it already
- * exists in the publishing directory and has an older modification time.
- * If the application mode is set as 'Performance', the modification time check
- * will be skipped. You can explicitly require a modification time check
- * with the function {@link publishFilePath}. This is usually
- * very useful during development.
- *
- * TAssetManager may be configured in application configuration file within
- * page service element as follows,
- * <module id="asset" BasePath="Application.assets" BaseUrl="/assets" />
- * where {@link getBasePath BasePath} and {@link getBaseUrl BaseUrl} are
- * configurable properties of TAssetManager. Make sure that BasePath is a namespace
- * pointing to a valid directory writable by the Web server process.
