title: Syslog rotation using log4cplus appender MaxFileSize and MaxBackupIndex
body: <p>I have below config, which seems to have no effect on the rotation of the syslog:</p>
  <blockquote>
  <p>log4cplus.appender.syslog=log4cplus::SysLogAppender
  log4cplus.appender.syslog.MaxFileSize=200KB</p>
  <p>log4cplus.appender.syslog.MaxBackupIndex=5
  log4cplus.appender.syslog.layout=log4cplus::PatternLayout
  log4cplus.appender.syslog.layout.ConversionPattern=[%T] %-5p %b %x -
  %m%n</p>
  </blockquote>
  <p>I would like to be able to manage syslog size and number of the backups.
  What would be correct way of doing this using Log4Cplus?</p>
