I tried to rewrite debian/copyright file in poppler-data package as "Machine-readable debian/copyright" mentioned.
But it's not easy, I should clear some things so I asked to that mailing list. Maybe they don't want to discuss such licensing issue, but I need it.
And one thing I don't understand is "BSD" license. There are 3 items.
BSD Berkeley software distribution license NetBSD NetBSD Foundation’s (TNF) license FreeBSD FreeBSD Project license
Now, NetBSD uses 2-clause BSD license (they used 4-clause in the past) and FreeBSD also uses 2-clause BSD license but they adds lines as below.
The views and conclusions contained in the software and documentation are those of the authors and should not be interpreted as representing official policies, either expressed or implied, of the FreeBSD Project.
And, how about OpenBSD? It is here, it's so simple.
Anyway, 2-clause BSD seems to be main for BSDs.
Today, I filled 4 tiny bugs about packages' section override, and after 11 hours, all of those bugs are fixed and closed. I'm happy because they respond so quickly.
And, as I see, today's Debian NEW and BYHAND Packages list is very short. There were 2 or 3 hundred packages that need to be checked by ftpmasters in the past. And now, it is less than 20! great.
