=head1 OPTIONS
=over 8
=item B<--help>
Prints a brief help message and exits.
=item B<--man>
Prints the manual page and exits.
=item B<--selection=<string>>
Many distributions offer several different package selections for
installation. With this option you can specify which of these you
would like to use.
If you pass an unknown selection, you will see a list of the selections
that are available.
In clone-mode, the selection specifies the name by which the cloned system
will be known (exact name will be '<distro>-<selection>' instead of
'<distro>-cloned-from-<rsync-source>').
=item B<--source=<string>>
When cloning a vendor-OS, slxos-setup needs to know where to fetch
the existing OS-files from. You can specify the rsync-uri with this
option.
=item B<--version>
Prints the version and exits.
