/*
 * This script demonstrates how you can take inputs from the user
 * through an interactive way by prompting users for inputs step by step.
 *
 * There's a few concepts being demonstrated here:
 *  1. how to print things in color
 *  2. how to take user inputs from the command line
 *  3. how to execute shell commands from within a kotlin script
 *
 * To run kscripts do it like so:
    $>  brew install kotlin
    $>  kotlin 3.input-from-shell.main.kts
 *
 * Alternatively, make this script executable
    $>  chmod +x <script-name>.main.kts
    $>  ./<script-name>.main.kts <args>
 *
 * Read more about this at https://kau.sh/blog/kscript
