Upgrade instructions

If you don't use pinning (see [1]) you have to update the package
manually via "apt-get -t lenny-backports install <packagelist>" with
the packagelist of your installed packages affected by this update.

We recommend to pin (in /etc/apt/preferences) the backports repository
to 200 so that new versions of installed backports will be installed
automatically.

Package: *
Pin: release a=lenny-backports
