prompt: Your task is to convert the following English description into an ASCII tree format.
  
  customDirs is a source directory that maintains 3 subdirectories: groovy, kotlin and tests.
  At the top level, 'groovy' includes 1 directories: test.
  At level 2, in directory path 'groovy > test', 'test' houses 1 folders for testing purposes.
  In nested path 'groovy > test > org', 'org' organizes 1 directories: example.
  In nested path 'groovy / test / org / example', 'example' is a vacant space.
  At the top level, 'kotlin' encapsulates 1 subdirectories: test.
  Within directory hierarchy 'kotlin > test', 'test' encapsulates 1 test-related directories.
  In nested path 'kotlin > test > org', 'org' shelters 1 child directories: example.
  Within directory hierarchy 'kotlin / test / org / example', 'example' contains nothing at present.
  Back to the top level.
  In the root directory, 'tests' remains unused.
  
  
  Format your response in this style:
  ```
  packages
   +--pkg-a
   |   `--src
   +--pkg-b
   |   `--src
   `--shared
       `--src
  ```
  
  Provide your answer wrapped in <ascii_formatted> tags.
