Usage

Create a bunyan logger using the stream:

    var log = bunyan.createLogger({
        name: 'foo',
        streams: [{
            stream: new RotatingFileStream({
                path: '/var/log/foo.log',
                period: '1d',          // daily rotation
                totalFiles: 10,        // keep up to 10 backup copies
                rotateExisting: true,  // Give ourselves a clean file when we start up, based on period
                threshold: '10m',      // Rotate log files larger than 10 megabytes
                totalSize: '20m',      // Don't keep more than 20mb of archived log files
                gzip: true             // Compress the archive log files to save space
            })
        }]
    });

Other options include startNewFile to always open a new file on start-up.
