# This script checks whether the testing.init symbol is present in any
# of the release binaries and fails if it finds one. This check is needed
# to avoid including test libraries in production binaries as they often lack
# rigorous review and sufficient testing.
# Usage: `hack/verify-test-code.sh`.
