You are correct. That is why I put gpl1+ Do we want to use version 1 of the GPL? I don't fully understand the issues with it, but it's an unusual choice. I don't have a strong opinion here. But there is a precedent in Guix, that where upstream permits a package to be distributed under a choice of licences, we simply present that choice to our users. We don't - at least I haven't seen any instances of it - choose a particular one that suits us, unless there is a good reason for doing that. J' -- Avoid eavesdropping. Send strong encrypted email.
