-    <para>A unit configuration file whose name ends in
-    <literal>.scope</literal> encodes information about a unit created
-    by systemd to encapsulate processes not launched by systemd
-    itself. This management is performed by creating a node in the
-    control group tree. Processes are moved into the scope by means
-    of the D-Bus API.

-    files. The common configuration items are configured
-    in the generic [Unit] and [Install] sections. The
