* A logging class which writes to UNIX syslog. This class can be dynamically
* loaded by SLPConfig and used as the log object by the writeLog and
* writeLogLine methods. Note that we need to use JNI here to call the
* native syslog. This is because syslog can be listening on any port
* mapped to 'syslog' in the services table, but Java provides no way to
* query this mapping.
*
* This class does not actually write anything until the flush() method
* in invoked; this will write the concatenation of all messages
* passed to the write() method since the last invokation of flush().
*
* The actual logging class used can be controlled via the
* sun.net.slp.loggerClass property.
*
* See also the SLPLog (in slpd.java) and StderrLog classes.
