+ * to force the Content-Disposition header to 'attachment', even for images and
+ * other file types that could normally be displayed by the browser. This is
+ * useful for "Download" links.
+ *
+ * By invoking hook_file_download() and checking access as file_download() does,
+ * this function is compatible with public and private files as well as other
+ * custom URI schemes that may be in use.
