Tracker bug for adding this to the tree. I have an initial attempt at an ebuild up at http://dirkjan.ochtman.nl/files/supervisor-3.0_alpha8.ebuild.
Created attachment 222733 [details] initial ebuild that works on amd64
Created attachment 222735 [details] conf.d file
Created attachment 222737 [details] init script
Someone should review licences, since I'm dark on that area:)
Sent email about the licensing situation to gentoo-dev. Otherwise, this is looking good, thanks!
It's in the tree now, thanks for checking it out.
