These Debian-Packages were re-build on this machine for the use on this machine. They are _usually_ simply backports from unstable to stable, without using special optimization, so they should work on every other stable machine. But don't be sure about that ;-) To use you should have these lines in your /etc/apt/sources.list: deb http://security.debian.org stable/updates main contrib non-free deb http://<your debian mirror>/debian/ stable main contrib non-free deb http://<your debian mirror>/debian-non-US stable/non-US main contrib non-free deb http://<your debian mirror>/debian/ unstable main contrib non-free deb http://<your debian mirror>/debian-non-US unstable/non-US main contrib non-free deb http://cord.de/proj/debian/backports stable main and /etc/apt/preferences Package: * Pin: release a=stable Pin-Priority: 800 Package: * Pin: release a=unstable Pin-Priority: 500 have fun, Cord
