리눅스의 가치?

SLOC(sloccount) 라는 소프트웨어가 있더군요...
단순하게 소스 코드의 줄 수를 세어보려 했는데...
재미있게도, 들어가는 비용이나, 개발 시간들도
산출해 주나 봅니다.
물론, 그 기준은 저도 모릅니다.
리눅스 코드를 넘겨 주니까
8년 개발 기간에 1800 억-_-; 이 나오더군요.
그리고 개인적으로 emacs 도 해봤는데,
눈에 띄는건 역시 emacs-lisp 군요.
C로 emacs-lisp 를 자체적으로 해석할수 있게 제작하고,
그 위에 emacs-lisp 로 확장하면서 emacs가
만들어 진듯 합니다 .
emacs 는 70만 라인에 emacs-lisp 코드가 가장 많고
260억 정도 나오는 군요.
linux 는 Driver 에 코드가 가장 많은거랑
C코드가 주류인것이 눈에 띄네요.(어셈도 저정도면 엄청 많은 거겠지만..)
다양한 장치를 지원하기 위함 이겠죠? :)
