+
+    <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>

+
+    <para><command>systemd-socket-activate</command> may be used to launch a socket-activated service binary from the command
+    line for testing purposes. It may also be used to launch individual instances of the service binary per connection.
+    </para>
+
+    <para>The daemon to launch and its options should be specified
+    after options intended for <command>systemd-socket-activate</command>.
+    </para>
+
+    <para>If the <option>--inetd</option> option is given, the socket file descriptor will be used as the standard
+    input and output of the launched process. Otherwise, standard input and output will be inherited, and sockets will
+    be passed through file descriptors 3 and higher. Sockets passed through <varname>$LISTEN_FDS</varname> to
+    <command>systemd-socket-activate</command> will be passed through to the daemon, in the original positions. Other sockets
+    specified with <option>--listen=</option> will use consecutive descriptors.  By default,
+    <command>systemd-socket-activate</command> listens on a stream socket, use <option>--datagram</option> and
+    <option>--seqpacket</option> to listen on datagram or sequential packet sockets instead (see below).
