prompt: Your task is to convert the following English description into an ASCII tree format.
  
  app is a principal directory that encompasses 2 subdirectories: node_modules and pages.
  In the root directory, 'node_modules' shelters 1 packages: notnext.
  At level 2, in directory path 'node_modules / notnext', 'notnext' shelters 1 subdirectory elements: dist.
  In nested path 'node_modules / notnext / dist', 'dist' stands empty.
  Back to the top level.
  At the main level, 'pages' is unpopulated.
  
  
  Format your response in this style:
  ```
  not-found-revalidate
   +--pages
   |   +--fallback-blocking
   |   +--fallback-true
   |   `--initial-not-found
   `--test
  ```
  
  Provide your answer wrapped in <ascii_formatted> tags.
