Cool!

OK!

Would be good eventually to add tests for =E2=80=98package-direct-dependent=
s=E2=80=99 & co.

Definitely!

I=E2=80=99m surprised gzip, diffutils, patch, and tar are very low, even th=
ough
they=E2=80=99re part of %final-inputs.  Conversely, bzip2 (also part of
%final-inputs) is higher.

Any idea?

Thanks,
