+/**
+ * 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 BasePath property together with the 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. You may require a timestamp checking by
+ * setting CheckTimestamp to true (which is false by default). You may also require
+ * so when calling {@link publishFile} or {@link publishDirectory). This is usually
+ * very useful during development. In production sites, the timestamp checking
+ * should be turned off to improve performance.
+ *
