"악취"는 안좋은 코드에 대한 비유이다. [켄트 벡](https://wiki.g15e.com/pages/Kent%20Beck.txt)이 제안.

## [Refactoring: Improving the design of existing code](https://wiki.g15e.com/pages/Refactoring%20-%20Improving%20the%20design%20of%20existing%20code.txt)에서 제안하는 악취 목록.

악취 목록이 [Mysterious name](https://wiki.g15e.com/pages/Mysterious%20name.txt)과 [Duplicated code](https://wiki.g15e.com/pages/Duplicated%20code.txt)로 시작하는 이유는 어쩌면 이 두 가지가 가장 중요하기 때문일 수도 있겠다. [Test-driven development: by example](https://wiki.g15e.com/pages/Test-driven%20development%20-%20By%20example.txt)에서 [켄트 벡](https://wiki.g15e.com/pages/Kent%20Beck.txt)은 [리팩토링](https://wiki.g15e.com/pages/Refactoring.txt)을 "의도 드러내기와 중복 제거"로 정의한다.
