inputs:
  release-version:
    description: >-
      The release where the artifact will be attached.
    required: true
  upload:
    description: >-
      Whether or not to upload the file and attestation to the release.  If this

    default: true
  attestation-name:
    description: >-
      This will be used for the artifact name that is attached to the workflow and
      will be used as the basename for the attestation file which will be called
      $attestation-name.jsonl.  If this is not set, it will default
      to the falue of `files`.
    required: false
  artifact-id:
    description: >-
      Artifact id of the artifact with the files to upload.
    required: true
  digest:
    description: >-
      sha256 digest to verify the authenticity of the files being uploaded.
    required: true
  LLVM_TOKEN_GENERATOR_CLIENT_ID:
    description: >-
      Client ID for our GitHub App we use for generating access tokens.
    required: true
  LLVM_TOKEN_GENERATOR_PRIVATE_KEY:
    description: >-
      Private key for our GitHub App we use for generating access tokens.
