# Tauri's bundler has no pacman target (as of tauri-cli 2.9.x), so we ship a
# hand-written PKGBUILD in packaging/arch/ and build it with makepkg. This must
# run on an Arch host / the `arch-build` Docker stage — makepkg is Arch-specific
# and refuses to run as root, so run it as a non-root user with sudo for deps.
#
# Usage (typically inside the arch-build Docker stage as a non-root user):
#   scripts/build-arch.sh
#   OUTPUT_DIR=/app/dist scripts/build-arch.sh
