# Installs the Battle.net launcher on Arch Linux via umu-launcher.

# Idempotent: safe to re-run. Skips steps that are already done.

#
|
|
# Usage:
|
|
# ./battlenet-umu-setup.sh # interactive
|
|
# ./battlenet-umu-setup.sh --yes # non-interactive, assume yes
|
|
# ./battlenet-umu-setup.sh --reinstall # wipe prefix and reinstall
|
|
#
|
|
# Does NOT run itself as root. It will call sudo only for pacman.
