This command allows to use more options. To specify Ubuntu release for which you are going to backport a package, use ``-d dest`` or ``--destination=DEST`` parameter, where ``DEST`` is Ubuntu release, for example ``xenial``. You can specify more than one destination. In turn, ``-s SOURCE`` and ``--source=SOURCE`` specifies the Ubuntu or Debian release from which you are going to backport a package. ``-w DIR`` and ``--workdir=DIR`` specifies directory, where package files will be downloaded, unpacked and built. By default, it will create temporary directory that will be automatically deleted. ``-U`` or ``--update`` allows to update build environment before building package. ``-u`` or ``--upload`` allows to upload package after building (for example to PPAs) using ``dput``.
