Just to add a bit to this topic. I'd find it preferrable, from a script writing POV, to keep package versions such that matching regexp /[.0-9]*/ on the Debian package's version number uniquely matches with the Cabal version. The alternative is to grab the source and peek in the .cabal file. I'd like to get by with just what dpkg's database knows.
Upstream gives little guarantees about it, but I'd still like to act like libraries are compatible as long as their cabal versions match. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmas...@lists.debian.org
