  // things that aren't needed for the hjar. However, this can be really expensive for the component
  // because it is usually the most expensive file to generate, and most of its content is not
  // needed in the hjar. Thus, instead of wrapping the ComponentGenerator in HjarSourceFileGenerator
  // we provide a completely separate processing step, ComponentHjarProcessingStep, and generator,
  // ComponentHjarGenerator, for when generating hjars for components, which can avoid generating
  // the parts of the component that would have been stripped out by the HjarSourceFileGenerator.
