I'm a software packager, and it's nice to be able to look at the way linux distros package files. I have a huge directory of package build scripts from archlinux, gentoo, void, alpine, and adélie linux and updating them all one at a time, or dealing with the huge amount of space that a fully deep .git directory takes up is really annoying. This script solved all my problems and I'm putting it here in hopes that someone else will find it useful too. Let me know if you use it in the comments below!!
