Currently this overlay isn't really actively maintained, since I switched over to Exherbo. In case you want to maintain one of the packages in this overlay in your own just copy it over ( would be nice if you opened an issue about it too, so that I drop mine)

This overlay is not official but is available in layman's repository. I try to keep the ebuilds up to date, but please open a issue if I missed an update
Use ebuilds supplied in this repository on your own risk. They've been tested on my own system setup (~amd64) and (most likely) tested on virtual systems (amd64 and x86).
