                identify and compare configuration files in
                <filename>/etc</filename> that override default
                counterparts in <filename>/usr</filename>. The command
                line argument can be one or more name of a subdirectories of
                <filename>/etc</filename> or
                <filename>/usr/lib</filename> to compare, such as
                <filename>tmpfiles.d</filename>, <filename>sysctl.d</filename> or
                <filename>systemd/system</filename>.</para>

                <para>When no argument is specified a number of
                well-known subdirectories are searched for overridden
                files.</para>
