Circumflex Docco is a Scala port of Docco project. It offers an alternative approach to maintain source code documentation in a literate programming style.
Unlike standard documentation tools Docco encourages developers to express their thoughts consistently by providing explanations, instructions, HOWTOs and usage scenarios side-by-side with corresponding code fragments.
Circumflex codebase is a live example of how Docco works.
