Hope you don't mind that I adapted this into a quick container image[1]. (Feel free to scoff at the idea of taking a simple bash script and making it into a massive Docker image; you're right, I just wanted a convenient way to run it in Linux environments that I don't have great control over.) I know it's not a huge script, but nonetheless if you want I can add a LICENSE/copyright notice in my fork/adaptation, if you want to pick a license for this script.
