+The operating system uses a special log file named @code{XXX}.
+This log file is called the system log and is automatically created and
+tracked by the operating system. The system log is written to with
+the @code{log_write} function. An alternative log file may be written
+using the @code{log_write_any} function. It is possible to use @code{log_read}
+to query the system and @code{log_write_entry} to a non-system log file
+to produce a filtered version of the system log. For example you could
+produce a log of all disk controller faults that have occurred.
+
+A non-system log may be a special log file created by an application to
+describe application faults, or a subset of the system log created
+by the application.
+
+A facility is an identification code for a subsystem, device, or
+other object about which information is being written to
+a log file. Severity is a rating of the error that is being logged.
+The facility identifier and the event severity are the basis for
+subsequent log query. A log query is used as a filter to
+obtain a subset of a given log file. The log file may be configured
+to send out an event ... ???
