# This script creates base images for focal, jammy, and noble. Then it builds the
# cl-repro-focal, cl-repro-jammy, and cl-repro-noble builder images. The base images are created using
# debootstrap, and the cl-repro images are created using the Dockerfiles in
# contrib/reprobuild. These builder images will finally be used to build the
# reproducible binaries.
# It automates the process described here:
# https://docs.corelightning.org/docs/repro#build-environment-setup
