+ <title>Description</title>
+
+ <para><command>systemd-activate</command> can be used to
+ launch a socket activated daemon from the command-line for
+ testing purposes. It can also be used to launch single instances
+ of the daemon per connection (inetd-style).
+ </para>
+
+ <para>The daemon to launch and its options should be specifed
+ after options intended for <command>systemd-activate</command>.
+ </para>
+
+ <para>If the <option>-a</option> option is given, file descriptor
+ of the connection 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-activate</command> will be passed through to
+ the dameon, in the original positions. Other sockets specified
+ with <option>--listen</option> will use consecutive descriptors.
