+# DESCRIPTION:
+#   This plugin monitors the status of applications and processes
+#   running under the bluepill process supervisor.
+#
+#   Specify applications to monitor with -a [APP1,APP2]
+#   If this option is not provided, this check will monitor the processes
+#   of all the applications that bluepill has loaded.
+#
+# OUTPUT:
+#   plain text
+#   Returns CRITICAL if any process is down or if a manually specified
+#   application has no processes loaded
+#   Returns WARNING if any process is starting or unmonitored
+#   Returns OK if all processes for all specified applications are 'up'
+#   or bluepill is not in $PATH
+#
