• Thread: https://unix.stackexchange.com/questions/717168/how-to-package-my-software-in-nix-or-write-my-own-package-derivation-for-nixpkgs
• UseCase: Split this experiment into multiple Build, Run, Test proof of concepts.
• Hint: Use Golang's txtar & scripttest modules to declare the Build, Run, Test workflow
• Note: .nix files will declare the Build recipes
