"""Updates the python scripts in python/perfetto/prebuilts/manifests
This script does the following, for each entry in MANIFESTS_TO_UPDATE:
- Downloads the artifact by the LUCI infrastructure, one for each arch.
- Computes the SHA-256 of each artifact.
- Generates a manifest with URL, SHA-256 and other details.
- Merges get_perfetto_prebuilt.py with the manifest and writes tools/xxx.
This script is supposed to be run by Perfetto OWNERS after every monthly release
after the LUCI jobs have completed.
