+    <title>Description</title>
+
+    <para>Scope units are not configured via unit configuration files,
+    but are only created programmatically using the bus interfaces of
+    systemd. They are named similar to filenames. A unit whose name
+    ends in <literal>.scope</literal> refers to a scope unit. Scopes
+    units manage a set of system processes. Unlike service units, scope
+    units manage externally created processes, and do not fork off
+    processes on its own.</para>
+
+    <para>The main purpose of scope units is grouping worker processes
+    of a system service for organization and for managing resources.</para>
+
+    <para><command>systemd-run <option>--scope</option></command> may
+    be used to easily launch a command in a new scope unit from the
+    command line.</para>
+
+    <para>See the <ulink
+    url="https://www.freedesktop.org/wiki/Software/systemd/ControlGroupInterface">New
+    Control Group Interfaces</ulink> for an introduction on how to make
+    use of scope units from programs.</para>
+
+    <para>Note that, unlike service units, scope units have no "main" process: all processes in the scope are
+    equivalent. The lifecycle of the scope unit is thus not bound to the lifetime of one specific process,
+    but to the existence of at least one process in the scope. This also means that the exit statuses of
+    these processes are not relevant for the scope unit failure state. Scope units may still enter a failure
+    state, for example due to resource exhaustion or stop timeouts being reached, but not due to programs
+    inside of them terminating uncleanly. Since processes managed as scope units generally remain children of
+    the original process that forked them off, it is also the job of that process to collect their exit
+    statuses and act on them as needed.</para>

+

+      <title>Implicit Dependencies</title>
+
+      <para>Implicit dependencies may be added as result of
+      resource control parameters as documented in

+        type <varname>Conflicts=</varname> and
+        <varname>Before=</varname> on
+        <filename>shutdown.target</filename>. These ensure
+        that scope units are removed prior to system
+        shutdown. Only scope units involved with early boot or
+        late system shutdown should disable
+        <varname>DefaultDependencies=</varname> option.</para></listitem>

+
+    <para>Scope files may include a [Unit] section, which is described in
+    <citerefentry><refentrytitle>systemd.unit</refentrytitle><manvolnum>5</manvolnum></citerefentry>.
+    </para>
+
+    <para>Scope files may include a [Scope]
+    section, which carries information about the scope and the
+    units it contains. A number of options that may be used in
+    this section are shared with other unit types. These options are
+    documented in
+    <citerefentry><refentrytitle>systemd.kill</refentrytitle><manvolnum>5</manvolnum></citerefentry>
+    and
+    <citerefentry><refentrytitle>systemd.resource-control</refentrytitle><manvolnum>5</manvolnum></citerefentry>.
+    The options specific to the [Scope] section
+    of scope units are the following:</para>

+
+        <listitem><para>This option modifies <varname>RuntimeMaxSec=</varname> by increasing the maximum runtime by an
