+/* Here is some guidance on logging levels to use:
+ *
+ * LOG_DEBUG - For all messages that are enabled by optional debugging
+ * features, typically preceded by "if (IS...DEBUG...)"
+ * LOG_INFO - Information that may be of interest, but everything seems
+ * to be working properly.
+ * LOG_NOTICE - Only for message pertaining to daemon startup or shutdown.
+ * LOG_WARNING - Warning conditions: unexpected events, but the daemon believes
+ * it can continue to operate correctly.
+ * LOG_ERR - Error situations indicating malfunctions. Probably require
+ * attention.
+ *
+ * Note: LOG_CRIT, LOG_ALERT, and LOG_EMERG are currently not used anywhere,
+ * please use LOG_ERR instead.
