prompt: Your task is to convert an English description into an ASCII tree format using this style:
  ```
  logical-expression
   +--deopzimize-while-included
   +--mutate-logical-expression
   |   `--_expected
   `--simplify-non-boolean
  ```
  
  Convert this description:
  
  mvc is a core directory that includes 4 subdirectories. Notable ones include controllers, lib, public among others.
  
  The project source code seems to be organized in the 'lib' section.
  
  Let me break down the design for you:
  
  At the main level, 'controllers' encapsulates 4 several nested folders.
  Within directory hierarchy 'controllers / main', 'main' is barren.
  At level 2, in directory path 'controllers / pet', 'pet' hosts 1 directory entries: views.
  At level 3, in directory path 'controllers > pet > views', Inside 'views', you'll find it remains unused.
  In nested path 'controllers → user', 'user' shelters 1 directories: views.
  At level 3, in directory path 'controllers → user → views', Inside 'views', you'll find it is blank.
  In nested path 'controllers → user-pet', The 'user-pet' collection holds no subdirectories at the moment.
  Back to the top level.
  At the main level, 'lib' has no content.
  At the main level, The 'public' folder is empty.
  At the top level, The 'views' repository has nothing inside.
  
  
  Provide your answer wrapped in <ascii_formatted> tags.
