prompt: Your task is to convert the following English description into an ASCII tree format.
  
  tests is a main directory that consolidates 4 subdirectories. Notable ones include _fixtures, _support, etc among others.
  
  Let me break down the composition for you:
  
  At the main level, '_fixtures' retains 2 subdirectory elements: images, nested.
  In nested path '_fixtures → images', 'images' stands empty.
  Within directory hierarchy '_fixtures / nested', 'nested' has been left empty.
  At the top level, '_support' hasn't been filled with any content.
  At the top level, The 'etc' repository lacks any subdirectories.
  At the top level, The 'sub' repository stands empty.
  
  
  Format your response in this style:
  ```
  contrib
   +--admin
   |   `--_images
   +--gis
   |   `--install
   `--postgres
  ```
  
  Provide your answer wrapped in <ascii_formatted> tags.
