prompt: Your task is to convert the following English description into an ASCII tree format.
  
  navigation is a fundamental directory that comprises 2 subdirectories: not-found and redirect.
  At the main level, 'not-found' groups 1 child directories: dynamic.
  In nested path 'not-found / dynamic', The 'dynamic' directory has no content.
  At the main level, 'redirect' includes 2 subdirectories: dynamic, location.
  At level 2, in directory path 'redirect / dynamic', The 'dynamic' data structure remains unused.
  At level 2, in directory path 'redirect / location', Inside 'location', you'll find it has nothing inside.
  
  
  Format your response in this style:
  ```
  packages
   +--pkg-a
   |   `--src
   +--pkg-b
   |   `--src
   `--shared
       `--src
  ```
  
  Provide your answer wrapped in <ascii_formatted> tags.
