+# Send notification in response to a given zevent.
+#
+# This is a generic script than can be symlinked to a file in the
+# enabled-zedlets directory to have a notification sent when a particular
+# class of zevents occurs.  The symlink filename must begin with the zevent
+# (sub)class string (e.g., "probe_failure-notify.sh" for the "probe_failure"
+# subclass).  Refer to the zed(8) manpage for details.
+#
+# Only one notification per ZED_NOTIFY_INTERVAL_SECS will be sent for a given
+# class/pool combination.  This protects against spamming the recipient
+# should multiple events occur together in time for the same pool.
+#
+# Exit codes:
+#   0: notification sent
+#   1: notification failed
+#   2: notification not configured
+#   3: notification suppressed
