+# options:
+#  - rate: the number of tokens (i.e. right to send a notification)
+#    gained per second. Defaults to 1.
+#  - max_burst: the maximum number of tokens outstanding. Defaults to 1000.
+#
+# With these defaults, falco could send up to 1000 notifications after
+# an initial quiet period, and then up to 1 notification per second
+# afterward. It would gain the full burst back after 1000 seconds of
+# no activity.
