Markdown syntax in Maven projects?

I love the Markdown syntax. I think it the most readable when in plain text, hence it is very easy to write as well, plus it has a large feature set. It can be used for writing blog posts, for instance.

I am looking forward to writing my documentation in Markdown in Java projects managed with Maven, instead of using APT.

Do you know any maven-markdown-plugin? If not, is the MarkdownJ implementation good (so that I can write the plugin myself)?
