I'm going to mark Geoffrey as having the copyright range up to 2025
because that's when I'm actually assembling this branch. Not like this
needs to be made as-if it was done at that point.
The previous copyright file indicated "LGPL" was an option. I think I
had done that because of the "GPLv3 *or later*" phrasing. I don't think
that's how it works -- the LGPL is not a "newer version" of the GPL.
The package should work properly, however the GTK4 dependency isn't
quite correct. The instructions from upstream suggest that the author is
using Fedora, not Debian. After testing real quick, it looks like Fedora
37 compiles properly, but Fedora 38 aborts with a deprecation warning
(-Werror=deprecated-declarations). Fedora 39 does the same, of
course.
