Me too.  (I do not understand easily the other one really.)

Very much luckily so my Linux distribution bundles both in one:

  source=(https://www.kernel.org/pub/linux/docs/$name/$name-$version.tar.xz
      https://www.kernel.org/pub/linux/docs/$name/$name-posix/$name-posix-2017-a.tar.xz)

I think Alejandro himself has problems with licenses, for bundling
out-of-the-box i mean.
