Thank you. Some comments follow.

But first and foremost, you need to provide a proper commit message, and
use `git format-patch' to send it to the list.  See Contributing section
in the manual, and examples of messages in the commits history of the
probject.

Package name and variable name are differents, this should be (name
"lief"), since it doesn't seem to be Python specific.

You can remove ".git" suffix here.

Hash string should go on the same line as base32.

I think this is the other way. You may use cmake-build-system, and
provide python-wrapper as a native input.

AFAIU, this is not a Python-only library. Besides, the description
should consist of full sentences.

I made the changes suggested above, but couldn't run the tests. Also,
I didn't build documentation. Eventually, the process seems to create
static libraries, it would be nice to remove them. Could you look into
it and see what is possible to do?
