+Store metadata in the extended file attributes.
+
+When saving output to a file, tell curl to store file metadata in extended
+file attributes. Currently, `curl` is stored in the `creator` attribute,
+the URL is stored in the `xdg.origin.url` attribute and, for HTTP, the content
+type is stored in the `mime_type` attribute. If the file system does not
+support extended attributes, a warning is issued.
