# Build, package, deploy, and verify TEESimulator module ZIPs.
# Usage: ./scripts/package.sh [flags]
#
# Examples:
#   ./scripts/package.sh --release                    # build release ZIP
#   ./scripts/package.sh --all --clean                # clean build, both variants
#   ./scripts/package.sh --release --deploy --reboot  # build, push, install, reboot
#   ./scripts/package.sh --deploy --verify            # deploy latest ZIP + verify via logcat
#   ./scripts/package.sh --rust --release             # build Rust crate first, then release

# Gradle's buildRustCertgen resolves `cargo` against the daemon's inherited PATH,
# not the env we inject via gradle's Exec.environment(). Prepend the per-user
# rustup install so non-login shells (CI, IDE-launched terminals, fresh tmux)
# still find it without sourcing /etc/profile.d/cargo-path.sh.
