    # This action originates from https://github.com/srvaroa/labeler. We are
    # using this action instead of the GitHub labeler action as the former
    # supports adding labels based on the number of changed, lines-of-code.
    # However, while the GitHub labeler action supports excluding files, the
    # action we are using does not. It would be nice if the GitHub labeler
    # action supported LoC labeling or if this action supported exclusions.
    # There are issues filed for both:
    #
    # * GitHub labeler LoC support:
    #   https://github.com/actions/labeler/issues/486
    #
    # * srvaroa labeler action exclusion support:
    #   https://github.com/srvaroa/labeler/issues/33
    #
    # For now we will use the srvaroa labeler action to afford ourselves the
    # support for LoC-based labels. If/when GitHub supports LoC, we will switch
    # to that and ignore the following, generated content:
    #
    # - "*_generated.go"       # generated Go sources
    # - "config/crd/bases/.*"  # generated CRDs
    # - "docs/apis/v*.md"      # generated API documentation,
    #                          # ex. docs/apis/v1alpha1.md
