Hello Maxime,

I will reply to all of your comments below.

It may be called a tool, but it is only a library, meant to be used from
other libraries.
The readme describes the basic usage as follows:

  import scooby
  scooby.Report()

The setup.py file lists psutil and mkl in extras_require, meaning they
are optional.
mkl (https://pypi.org/project/mkl/) is released under the Intel
Simplified Software License, which I suspect is ideologically
incompatible with Guix (and therefore not already packaged for Guix), so
I didn't include it.
I omitted psutil just because I was omitting mkl, but I can add it as a
propagated input.

It seems the test suite expects the import of a missing package to throw
an OSError instead of a ModuleNotFoundError, which is not the case at
least on Python 3.9.9.
I don't know if it was different before.
I can add a comment to that effect.

The synopsis and description are taken wholesale from Scooby's readme.
However, I can rewrite them.
