prompt: Your task is to convert an English description into an ASCII tree format using this style:
  ```
  docs
   +--dsl
   |   +--docbook
   |   |   `--model
   |   +--links
   |   `--source
   |       `--model
   `--model
  ```
  
  Convert this description:
  
  app is a master directory that includes 5 subdirectories. Notable ones include error, null, object among others.
  
  Let me break down the construction for you:
  
  At the top level, 'error' awaits content.
  At the main level, The 'null' folder appears to be unused.
  At the main level, Inside 'object', you'll find it sits empty.
  At the main level, 'routes' organizes 4 many directories.
  Within directory hierarchy 'routes → error', Inside 'error', you'll find it has been left empty.
  Within directory hierarchy 'routes > object', The 'object' repository is vacant.
  Within directory hierarchy 'routes > string', 'string' hasn't been filled with any content.
  At level 2, in directory path 'routes → undefined', Inside 'undefined', you'll find it appears to be unused.
  Back to the top level.
  At the top level, Inside 'string', you'll find it is devoid of content.
  
  
  Provide your answer wrapped in <ascii_formatted> tags.
