+   requires the :program:`compress` program. Notice that this format is now
-   :program:`bzip2`, or :program:`compress`

+When using any ``tar`` format (``gztar``, ``bztar``, ``ztar`` or ``tar``), you
+can specify under Unix the ``owner`` and ``group`` names that will be set for
+each member of the archive.

+For example, if you want all files of the archive to be owned by root::
