Simply run npm install to install dependencies, then add new class and/or function files in lib and add an export entry in lib/index.js. This will eventually be more dynamic in near future. gluctl serves as the main entrypoint to everything. There it runs the commandRunner helper function which accepts a command and any number of args.
Exports format in index.js should follow this format to work:
export { SnakeCase as lowercase } from './ClassName.mjs'
