Lennart Poettering 3802a3d3d7 man: add emacs header to get correct indention in nxml-mode for the manpage XML files that use 2ch indenting
In the long run we really should figure out if we want to stick with 8ch
or 2ch indenting, and not continue with half-and-half. For now, just
make emacs aware of the files that use 2ch indenting.

<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="http://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>Unless <varname>DefaultDependencies=false</varname>
is used, scope units will implicitly have dependencies of
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 this option.
