# Prefers `cargo about` (full, network-augmented license harvest; see about.toml) and falls back to
# the dependency-free offline generator (scripts/gen-third-party-notices.py, reads the cargo registry
# cache). Run this when the dependency tree changes; CI also runs it before packaging.

# Usage: scripts/gen-third-party-notices.sh [output-file]
