"""
Utility that updates the metadata of the Transformers library in the repository `huggingface/transformers-metadata`.
Usage for an update (as used by the GitHub action `update_metadata`):
```bash
python utils/update_metadata.py --token <token> --commit_sha <commit_sha>
```
Usage to check all pipelines are properly defined in the constant `PIPELINE_TAGS_AND_AUTO_MODELS` of this script, so
that new pipelines are properly added as metadata (as used in `make repo-consistency`):
```bash
python utils/update_metadata.py --check-only
```
