+
+    <para><command>systemd-escape</command> may be used to escape
+    strings for inclusion in systemd unit names. The command may be
+    used to escape and to undo escaping of strings.</para>
+
+    <para>The command takes any number of strings on the command line,
+    and will process them individually, one after another. It will
+    output them separated by spaces to stdout.</para>
+
+    <para>By default, this command will escape the strings passed,
+    unless <option>--unescape</option> is passed which results in the
+    inverse operation being applied. If <option>--mangle</option> is given, a
+    special mode of escaping is applied instead, which assumes the
+    string is already escaped but will escape everything that
+    appears obviously non-escaped.</para>

+    be passed through file descriptors 3 and higher. Sockets passed through <varname>$LISTEN_FDS</varname> to
