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:
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.
