Alchemy/init.sh

#!/usr/bin/env bash

# This is the initialization script for Alchemy. We can't rely on all systems being able to use 'make' or other utilities by default.
# This will ensure that everything is set up as needed.
# Bare Metal Alchemist, 2022

# This runs the ingredients script as part of this one,
# making sure that some basic values / variables are defined
