         gram.  It consists of lines with two fields: the selector field which
         specifies the types of messages and priorities to which the line applies,
         and an action field which specifies the action to be taken if a message
         syslogd receives matches the selection criteria.  The selector field is
         separated from the action field by one or more tab or space characters. A
         rule can be splitted in several lines if all lines except the last are
         terminated with a backslash (''?').
         The Selectors function are encoded as a facility, a period (''.''), and a
         level, with no intervening white-space.  Both the facility and the level
         are case insensitive.
         The facility describes the part of the system generating the message, and
         is one of the following keywords: auth, authpriv, cron, daemon, kern,
         lpr, mail, mark, news, syslog, user, uucp and local0 through local7.
         These keywords (with the exception of mark) correspond to the similar
         "LOG_" values specified to the openlog(3) and syslog(3) library routines.
         The level describes the severity of the message, and is a keyword from
         the following ordered list (higher to lower): emerg, alert, crit, err,
         warning, notice and debug.  These keywords correspond to the similar
         (LOG_) values specified to the syslog library routine.
         See syslog(3) for a further descriptions of both the facility and level
         keywords and their significance.
         If a received message matches the specified facility and is of the speci-
         fied level (or a higher level), the action specified in the action field
         will be taken.
         Multiple selectors may be specified for a single action by separating
         them with semicolon ('';'') characters.  It is important to note, how-
         ever, that each selector can modify the ones preceding it.
         Multiple facilities may be specified for a single level by separating
         them with comma ('','') characters.
         An asterisk (''*'') can be used to specify all facilities or all levels.
         By default, a level applies to all messages with the same or higher
         level.  The equal (''='') character can be prepended to a level to
         restrict this line of the configuration file to messages with the very
         same level.
         An exclamation mark (''!'') prepended to a level or the asterisk means
         that this line of the configuration file does not apply to the specified
         level (and higher ones). In conjunction with the equal sign, you can
         exclude single levels as well.
         The special facility ''mark'' receives a message at priority ''info''
         every 20 minutes (see syslogd(8)).  This is not enabled by a facility
         field containing an asterisk.
             by a pathname. The pipe must be created with mkfifo(8) before syslogd
             reads its configuration file.  This feature is especially useful fo
         ?   A hostname (preceded by an at (''@'') sign).  Selected messages are
             forwarded to the syslogd program on the named host.
         ?   A comma separated list of users.  Selected messages are written to
             those users if they are logged in.
         ?   An asterisk.  Selected messages are written to all logged-in users.
         Blank lines and lines whose first non-blank character is a hash (''#'')
         character are ignored.


         A configuration file might appear as follows:
         # Log all kernel messages, authentication messages of
         # level notice or higher and anything of level err or
         # higher to the console.
         # Don't log private authentication messages!
         *.err;kern.*;auth.notice;authpriv.none  /dev/console
         # Log anything (except mail) of level info or higher.
         # Don't log private authentication messages!
         *.info;mail.none;authpriv.none          /var/log/messages
         # The authpriv file has restricted access.
         authpriv.*                                              /var/log/secure
         # Log all the mail messages in one place.
         mail.*                                                  /var/log/maillog
         # Everybody gets emergency messages, plus log them on another
         # machine.
         *.emerg                                                 *
         # Root and Eric get alert and higher messages.
         *.alert                                                 root,eric
         # Save mail and news errors of level err and higher in a
         # special file.

         The effects of multiple selectors are sometimes not intuitive.  For exam-
