      You can add schema providers as follows:

      # config/initializers/journaled.rb
      Journaled.schema_providers << MyGem::Engine
    ERROR
  end

  def gem_paths
    Journaled.schema_providers.map do |engine|
      engine.root.join "journaled_schemas/#{schema_name}.json"
    end
  end
end
