Easy verification of source for other people building the package (here
from AUR, but could be from ABS). Or maybe I misunderstood the point of
having PGP verification in makepkg?

The idea is to be able to just put the .dsc file in the sources array
and extract the checksum from it in the sha*sums array (here I just
write "$(grep -A1 Sha256 ${pkgname}_${pkgver}-1.dsc | tail -n 1 | cut -d
' ' -f 2)" in there), while having makepkg verify the .dsc file.

Anyway, I understand your point, I never thought the format could be
something else than a PGP signed message with or without detached
signature. Or maybe you were thinking of extracting the sha*sums (which
is then probably linked to my first point — my possible misunderstanding
of PGP verification in makepkg)?

Thanks,
Bruno
