+Insert a special code before the hostname in each message to indicate the
+message's priority and facility. Having the priority and facility encoded in
+each message allows a log analyzer program to monitor a single file
+containing all logged messages. The analyzer program can parse the
+priority/facility code for each logged message to determine if it is
+of interest.
+
+The priority/facility code takes the form of a priority number
+followed by a letter that indicates the facility. The priority number
+can range from 0 to 7. The  facility letter can range from 'A' to 'Y',
+where 'A' corresponds to facility number zero (LOG_KERN), 'B'
+corresponds to facility 1 (LOG_USER), etc.
+See /usr/include/sys/syslog.h for a list of priority and LOG_xxx codes.
+
+Example:
+
+      Jun 27 19:22:20 5Q:silence test[1966]: testing
+
+The above message contains a priority/facility code of '5Q', which breaks
+down to a priority of 5 (LOG_NOTICE) and a facility of 16 (LOG_LOCAL0).
