# This script runs the Kubernetes code generators for our custom resources.
# In a full setup, this would invoke deepcopy-gen, client-gen, lister-gen,
# informer-gen, and Knative's injection-gen.
#
# For now, the deepcopy functions are hand-written in zz_generated.deepcopy.go.
# This script serves as the entrypoint for when full code generation is wired up.
