node.js express middleware 중에서 logger를 사용하여 실제 파일로 logging 하는 방법

	/**
	* express 처음에 init 하시면 app.js 를 비롯하여 여러 디렉토리가 생기는데
	* logs 디렉토리에 아무것도 안남는다고 의문을 가지신 분에게 도움이 될거 같습니다.
	* connect의 middleware logger 는 기본이 stdout 으로 출력하고 있었네요.
	* http://senchalabs.github.com/connect/middleware-logger.html
	* manual을 살펴보니 stream options 이 있었군요.
	* 한번 생각나서 fs core module의 createWriteStream 을 사용하여 해봤더니 잘되네요.
	* 다른 방법도 있으신분은 알려주세요
