# Commentary
#
# This script sets up an Arch Linux distrobox setup for software development.
#
# There are two levels of errors:
# * CRASH: Issues that will halt forward progress, aborting this script.
# * ERROR: Issues not serious enough to halt the script.
# Both are printed on screen and in the $logfile.
# Stderr is also printed to the $logfile for all relevant info.
#
# # Code

# uncomment to stop on any error
# set -e
