Thanks to @borkdude who helped me get a Babashka script to run a program, which needs to prompt for a password from the user. He gave me a snapshot (babashka-1.3.189-SNAPSHOT), which fixed a bug in the most recently released version (preventing it from prompting for a password) and patiently babysat me until I got the correct arguments and datatypes to make it actually work.

Much thanks to @jr0cket for the beginner-friendly spacemacs setup guide for Clojure development.
