I really need a more mature example to show, which will be coming soon. However, many tools exist which are just eesentially auto documentation (java docs, literate Haskell, docco). Mine is the simplest iteration of a true literate programming tool which allows for code to be restructured in the way best fit for explanation. If you look at cweb, funnel-web, noweb, mine attempts to be a modern version that still implements macro functionality in a modern context (markdown, HTML, easy to build). Literate programming is more than just comments.
