#!/bin/bash
#
# This is a wrapper around ansible / ansible-playbook that uses the
# [Ansible Suitecase](https://github.com/epfl-si/ansible.suitecase).
#
# Usage ("ansible" mode):
#   ./ansible/k3sible -m raw all -a 'date'
#
# Usage ("ansible-playbook" mode):
#   ./ansible/k3sible
#
# If you are unfamiliar with Ansible, read up on it at
