I just got approached by Fedora maintainers with the query that HLint doesn't specify it's license fully. The License field in the cabal file says "GPL", and the LICENSE file has a copy of the GPL v2, but I never say GPL version 2, or GPL version 2 and above etc. What is the Cabal approved way to indicate your licensing constraints? I suspect all other distro's packaging HLint have just guessed, or gone GPL 2 because that's clearly a subset of what I might have intended.
There is a similar problem with some packages (ie bzlib) having BSD3 in the .cabal file but having a 2 clause BSD LICENSE file. This caused problems for me when I packaged bzlib for Debian.
Ah yes, I was going to add in: 3. This clause is intentionally left blank. :-) We need a consensus if we're to add an extra license name. The OSI do not list the 2-clause BSD license at all. The FSF describe it as the FreeBSD license or "2-clause BSD license". We currently have "BSD3" (and the outdated "BSD4"). We could add the 2-clause BSD license as "BSD2". What do other people call it, eg distros? I don't like the possible confusion over "BSD-$N" vs "GPL-N". The latter is a version while the former is not. If we'd had better foresight we would never have added BSD4 and could then have claimed that "BSD" covered both the 2 and 3 clause versions. We're not trying to nail down every last nuance in the licenses (e.g. I don't think we need to be trying to distinguish GPL-2 from GPL-2+). Duncan
