prompt: Your task is to convert the following English description into an ASCII tree format.
  
  packages is a source directory that encompasses 2 subdirectories: pkg-a and pkg-b.
  At the main level, 'pkg-a' carries 1 subfolders: src.
  In nested path 'pkg-a > src', Inside 'src', you'll find it is currently empty.
  At the top level, 'pkg-b' encompasses 1 nested folders: src.
  In nested path 'pkg-b / src', The 'src' collection is barren.
  
  
  Format your response in this style:
  ```
  node_modules
   +--@somenamespace
   |   `--eslint-formatter-foo
   `--eslint-formatter-bar
  ```
  
  Provide your answer wrapped in <ascii_formatted> tags.
