# Build Linux packages from the pre-built xrpld and validator-keys artifacts:
#
#   - one job per config that carries a "package" map in linux.json
#   - that map names the container image and the format it builds there
#   - every job ends with the image's publish_pkg.py, uploading what it built
#     with 'publish: true' and doing a --dry-run otherwise
#
# Only linux/amd64 is supported; the runner is hardcoded in the job below.
