      e.g. "directory_levels: 1" will provide the first level (in the
      repository root) directories that contain changes, no matter how

  exclude:
    description: >-
      Exclude directories that match the pattern.  If overriding,
      remember to include matching /^\\.github\\/.*/.

      Exclusion is applied after discovering changes based on the
      pattern.

      This should be a regular expression pattern.
