``Gromit, that's it! Cheese!''
Using Debian's required package, you can learn a lot about French cheeses:
$ aptitude changelog login | awk -F\" '/The ".+" release/ {print $2}' Tome des Bauges Chevrotin Banonet Banon Chambérat Le Puant Macéré Rocamadour Morbier Bleu des Causses Bleu d'Auvergne ...
Without Debian the command would be longer:
wget -qO - http://packages.debian.org/changelogs/pool/main/s/shadow/current/changelog.txt | awk -F\" '/The ".+" release/ {print $2}'
