prompt: Your task is to convert an English description into an ASCII tree format using this style:
  ```
  main
   +--java
   |   `--com
   |       `--example
   |           `--worker
   `--resources
       `--META-INF
           `--gradle-plugins
  ```
  
  Convert this description:
  
  unit is a origin directory that assembles 6 subdirectories. Notable ones include api, charset, eval among others.
  
  Let me break down the design for you:
  
  In the root directory, The 'api' section is blank.
  In the root directory, Inside 'charset', you'll find it contains nothing at present.
  At the top level, The 'eval' data structure awaits content.
  At the top level, The 'fixtures' section is currently empty.
  In the root directory, 'os' holds no subdirectories at the moment.
  In the root directory, 'viml' houses 1 nested folders: expressions.
  At level 2, in directory path 'viml / expressions', Inside 'expressions', you'll find it is vacant.
  Back to the top level.
  
  
  Provide your answer wrapped in <ascii_formatted> tags.
