  Convert this description:
  
  build-time-error is a fundamental directory that maintains 2 subdirectories: app and utils.
  In the root directory, The 'app' section houses 2 folders for code organization.
  In nested path 'app / page-throws-in-after', 'page-throws-in-after' comprises 2 subdirectories: callback, promise.
  At level 3, in directory path 'app → page-throws-in-after → callback', Inside 'callback', you'll find it is blank.
  At level 3, in directory path 'app → page-throws-in-after → promise', 'promise' is a vacant space.
  At level 2, in directory path 'app > route-throws-in-after', 'route-throws-in-after' houses 2 subdirectory elements: callback, promise.
  Within directory hierarchy 'app → route-throws-in-after → callback', The 'callback' repository is blank.
  In nested path 'app → route-throws-in-after → promise', 'promise' is an empty container.
  Back to the top level.
  At the top level, The 'utils' repository is unpopulated.
