DESCRIPTION: There are a few Debian meta packages but they are really broad. Example: it would be great if there were a few developer leaning packages grouped into one meta package.
For instance, I always install etckeeper, apt-listchanges and apt-listbugs. I think anyone following testing or unstable would want to install those and I'm not aware of any real alternatives to those. I can't imagine using unstable without apt-listbugs to warn you when there high priority bugs in the packages that were already uploaded.
DISTRIBUTION: mixture of testing/unstable.
