+# This is a simple script which will output a single line of info, and exit
+# with a return code which indicates status of a given systemd service.  It was
+# designed for use with Shinken monitoring.  Invoke like so:
+#
+#    check-systemd-service NAME
+#
+# Where NAME refers to the process, e.g. 'rattail-soffice'.  Exit code may be:
+#
+#  * 0 = process is confirmed running
+#  * 2 = process is confirmed *not* running
+#  * 3 = unknown state
