I made a replacement for the venerable paccheck. It checks if files managed by the package manger have changed and if so reports that back to the user. Unlike paccheck it is cross distro (supports Debian too and could be further extended), and it uses all your CPU cores to be as fast as possible.

Oh and it is written in Rust (that may be a plus or minus depending on your opinion, but it wouldn't have happened at all in any language except Rust, and Rust makes it very easy to add this sort of parallelism).

There are more details (including benchmarks) in the readme on github. Maybe it is useful to some of you.

(The main goal of this project is not actually the program produced so far, but to continue building this into a library. I have a larger project in the planning phase that needs this (in library form) as part of it.)
