+	  systemd-journal-remote is a command to receive serialized
+	  journal events and store them to journal files. Input
+	  streams are in the Journal Export Format[1], i.e. like the
+	  output from journalctl --output=export. For transport over
+	  the network, this serialized stream is usually carried over
+	  an HTTPS connection.
