This has sat in accepted for inclusion for over 30 days. Clearly, there is a lack of demand for the inclusion of this software, nobody has stepped up to provide a completed patch, maintain it, and properly integrate it. Closing as a result. Feel free to reopen but only when someone offers a patch via our proper patch submission methods and volunteers to be maintainer.
