+
+                <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 the other. 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> a special mode
+                of escaping is applied instead, which assumes a string
+                to be already escaped but will escape everything that
+                appears obviously non-escaped.</para>
