 > I'm looking for a maintainer for this project. I have lost my [Open Source Stamina](https://medium.com/@kentcdodds/open-source-stamina-dafd063f9932#.sfay5wlzp) for this project and I will probably not push any code to this project anymore (unless, I find some motivation later). I will try to merge pull requests if some are submitted, but only if they are really clean.
