This is a Gentoo overlay that contains some local builds of my own.
To use it install layman and edit your /etc/layman/layman.cfg to read:
overlays : http://www.gentoo.org/proj/en/overlays/repositories.xml
http://raw.github.com/iffsid/iffsid-local/master/repositories.xml
and run:
layman -a iffsid-local
