SYSLOG parameter*   ==  SYSLOG=[syslogOpts,][syslogServ]
        syslogOpts  ==  syslogOpt[,syslogOpts]
         syslogOpt  ==  -vt | -vs | -vS | -vH | -fname
                    --  default: none

This parameter specifies recording log data via the "syslog" service (RFC3164). The "facility.priority" pair of logged data of LOGFILE is "daemon.debug" for usual data and "daemon.err" for errors. (It will be divided into more detailed levels in the future.) The log data of PROTOLOG is sent with "daemon.notice". The facility name can be changed with a "-fname" option.

Multiple SYSLOG parameters can be specified to send a log data to multiple different destinations each specified by a syslogServ. A syslogServ is a URL of a syslog server or a local file. The default syslogServ is the local logger to which log is sent via the standard "syslog()" function. For each destination, the log format or detailness can be specified by prefixing a list of syslogOpt as follows:

-vt	-- terse LOGFILE
-vs	-- without LOGFILE
-vS	-- without PROTOLOG
-vH	-- without the syslog header
-fname	-- use the facility name instead of "daemon"

Example:

SYSLOG=	-- to the local syslog
SYSLOG=syslog://host	-- to a remote syslog server
SYSLOG=syslog://host:port	-- on a non-standard port
SYSLOG=/dev/tty	-- to the console
SYSLOG=file:path	-- to a local file
SYSLOG=-vH,file:path	-- without the syslog header
SYSLOG=-fdaemon	-- as the "daemon" facility (default)
SYSLOG=-flocal1	-- as the "local1" facility

The source port (and the address) of syslog UDP packets to a remote syslog server can be specified as SRCIF=":8514:syslog" (or SRCIF="xx.xx.xx.xx:8514:syslog") for example.
Switching syslog servers based on each client and server of the application protocol is not (yet) supported.
