prompt: Your task is to convert the following English description into an ASCII tree format.
  
  route-matcher-providers is a head directory that organizes 2 subdirectories: dev and helpers.
  In the root directory, 'dev' retains 1 directory entries: helpers.
  At level 2, in directory path 'dev / helpers', 'helpers' retains 1 child directories: file-reader.
  In nested path 'dev > helpers > file-reader', 'file-reader' has nothing inside.
  In the root directory, 'helpers' has 1 contained folders: manifest-loaders.
  In nested path 'helpers / manifest-loaders', 'manifest-loaders' has yet to be populated.
  
  
  Format your response in this style:
  ```
  kotlin
   +--my-sub-project
   `--src
       +--main
       |   `--java
       `--test
           `--java
  ```
  
  Provide your answer wrapped in <ascii_formatted> tags.
