Building a new rotate file writer:

rfw := l4g.NewRotateFileWriter("_rfw.log").SetMaxSize(1024 * 5).SetMaxBackup(10)

Setting maxium file size as 5M, and keeping only 10 files.

Or:

rfw := l4g.NewRotateFileWriter("_rfw.log").SetDaily(true)

Rotating file every day at midnight.

Setting output as MultiWriter

Logging message to term console and rotate file writer too.

ww := io.MultiWriter(os.Stderr, rfw)
// Get a new logger instance
log := l4g.New(l4g.FINEST).SetOutput(ww).SetPattern("[%D %T] [%L] (%s) %M\n")

Do not forget CLOSE rotate file writer

Call Close() function at the end of main program.

It is necessary to guarantee that all log messages are written.

rfw.Close()
