+    <title>Description</title>
+
+    <para><command>systemd-delta</command> may be used to identify and
+    compare configuration files that override other configuration
+    files. Files in <filename>/etc/</filename> have highest priority,
+    files in <filename>/run/</filename> have the second highest
+    priority, …, files in <filename>/usr/lib/</filename> have lowest
+    priority. Files in a directory with higher priority override files
+    with the same name in directories of lower priority. In addition,
+    certain configuration files can have <literal>.d</literal>
+    directories which contain "drop-in" files with configuration
+    snippets which augment the main configuration file. "Drop-in"
+    files can be overridden in the same way by placing files with the
+    same name in a directory of higher priority (except that, in case
+    of "drop-in" files, both the "drop-in" file name and the name of
+    the containing directory, which corresponds to the name of the
+    main configuration file, must match). For a fuller explanation,
+    see
+    <citerefentry><refentrytitle>systemd.unit</refentrytitle><manvolnum>5</manvolnum></citerefentry>.
+    </para>
+
+    <para>The command line argument will be split into a prefix and a
+    suffix. Either is optional. The prefix must be one of the
+    directories containing configuration files
+    (<filename>/etc/</filename>, <filename>/run/</filename>,
+    <filename>/usr/lib/</filename>, …). If it is given, only
+    overriding files contained in this directory will be shown.
+    Otherwise, all overriding files will be shown. The suffix must be
+    a name of a subdirectory containing configuration files like
+    <filename>tmpfiles.d</filename>, <filename>sysctl.d</filename> or
+    <filename>systemd/system</filename>. If it is given, only
+    configuration files in this subdirectory (across all configuration
+    paths) will be analyzed. Otherwise, all configuration files will
+    be analyzed. If the command line argument is not given at all, all
+    configuration files will be analyzed. See below for some
+    examples.</para>
