Apparently, there is a mkdocs apt package available for this using Markdown syntax, see also http://www.mkdocs.org/

The rosdoc tool got a new name, it's rosdoc_lite nowadays, apparently, but both tools look complimentary in nature. mkdocs handles creation of the document-files of one project (markdown syntax in readthedocs style output), while rosdoc_lite seems to cover generation for several kinds of documentation generator across several ros-packages.
