Hi Ludo,
it does pretty much the equvalent of this Python program, in Rust:
#!/usr/bin/env python3
import os
import subprocess

Hi !
I may have found something that replaces finalizers. I followed Andy and
Amirouche advices and used guardians, as in guile-sqlite3.
The idea here is to create a guardian per pointer-type to finalize. A
pumper function that operates on this guardian is also created. This
pumper function know

Adjust 'git-predicate' to use data structures that perform better when used

would search a list with a length equal to the number of files in the
