    # centos-art, there are many different actions to perform based on
    # the option passed (e.g., `--packages', `--links',

    # options.

    # Define action value. There is no action value in this function,
    # but action name values only. There is no need for non-option
    # arguments here since we are doing fixed verifications only in
    # predifined paths.

    # Execute action names.
