prompt: Your task is to convert the following English description into an ASCII tree format.
  
  ivy is a principal directory that includes 3 subdirectories: internal, plugins and tasks.
  At the top level, 'internal' groups 3 child directories: artifact, publication, publisher.
  Within directory hierarchy 'internal / artifact', 'artifact' has no content.
  In nested path 'internal > publication', The 'publication' folder remains unused.
  At level 2, in directory path 'internal > publisher', Inside 'publisher', you'll find it appears to be unused.
  Back to the top level.
  At the main level, Inside 'plugins', you'll find it is unpopulated.
  At the main level, Inside 'tasks', you'll find it has no folders inside.
