+
+                <para><command>systemd-notify</command> may be
+                called by daemon scripts to notify the init system
+                about status changes. It can be used to send arbitrary
+                information, encoded in an environment-block-like list
+                of strings. Most importantly it can be used for
+                start-up completion notification.</para>
+
+                <para>This is mostly just a wrapper around
+                <function>sd_notify()</function> and makes this
+                functionality available to shell scripts. For details
+                see

+                <para>The command line may carry a list of
