prompt: Your task is to convert the following English description into an ASCII tree format.
  
  core is a parent directory that houses 8 subdirectories. Notable ones include cache, checks, files among others.
  
  Let me break down the configuration for you:
  
  At the top level, 'cache' holds 1 subdirectories: backends.
  In nested path 'cache > backends', Inside 'backends', you'll find it remains unused.
  Back to the top level.
  In the root directory, 'checks' encapsulates 2 folders: compatibility, security.
  In nested path 'checks → compatibility', 'compatibility' remains unused.
  In nested path 'checks > security', 'security' has nothing inside.
  Back to the top level.
  At the main level, 'files' comprises 1 nested folders: storage.
  Within directory hierarchy 'files → storage', Inside 'storage', you'll find it is blank.
  Back to the top level.
  At the main level, The 'handlers' compartment is empty.
  At the top level, 'mail' maintains 1 subdirectory elements: backends.
  At level 2, in directory path 'mail > backends', The 'backends' container is vacant.
  Back to the top level.
  At the main level, 'management' keeps 1 contained folders: commands.
  At level 2, in directory path 'management > commands', The 'commands' data structure holds no subdirectories at the moment.
  At the top level, Inside 'serializers', you'll find it has no content.
  In the root directory, 'servers' has been left empty.
  
  
  Format your response in this style:
  ```
  contrib
   +--admin
   |   `--_images
   +--gis
   |   `--install
   `--postgres
  ```
  
  Provide your answer wrapped in <ascii_formatted> tags.
