Comment 3 for bug 190913

The problem is that GPLv2+ and GPLv2 are very different licenses right now. If I'm writing a GPLv3 app I can't use GPLv2 code but I can use GPLv2+ so while it is confusing it's also pretty important. I'm not sure if Launchpad wants to be responsible for helping users with licensing but something like what Fedora does at http://fedoraproject.org/wiki/Licensing#GPLCompatibilityMatrix might be helpful.
