prompt: Your task is to convert the following English description into an ASCII tree format.
  
  fixtures is a master directory that encompasses 2 subdirectories: modified-files and regular-fixtures.
  At the top level, 'modified-files' contains 2 contained folders: out, src.
  Within directory hierarchy 'modified-files → out', Inside 'out', you'll find it awaits content.
  At level 2, in directory path 'modified-files > src', 'src' is devoid of content.
  At the top level, 'regular-fixtures' maintains 2 subdirectories: out, src.
  At level 2, in directory path 'regular-fixtures → out', 'out' shelters 1 folders: sub.
  At level 3, in directory path 'regular-fixtures → out → sub', The 'sub' folder is currently empty.
  In nested path 'regular-fixtures → src', The 'src' storage space contains 1 folders for code organization.
  In nested path 'regular-fixtures > src > sub', 'sub' is currently empty.
  Back to the top level.
  
  
  Format your response in this style:
  ```
  packages
   +--pkg-a
   |   `--src
   +--pkg-b
   |   `--src
   `--shared
       `--src
  ```
