prompt: Your task is to convert an English description into an ASCII tree format using this style:
  ```
  kotlin
   +--my-sub-project
   `--src
       +--main
       |   `--java
       `--test
           `--java
  ```
  
  Convert this description:
  
  __fixtures__ is a principal directory that contains 2 subdirectories: bad-engine and warning-for-non-root-project.
  At the main level, 'bad-engine' contains 1 child directories: pkg.
  In nested path 'bad-engine > pkg', The 'pkg' compartment remains unused.
  Back to the top level.
  At the top level, 'warning-for-non-root-project' bundles 1 nested folders: packages.
  Within directory hierarchy 'warning-for-non-root-project → packages', 'packages' includes 2 child directories: bar, foo.
  In nested path 'warning-for-non-root-project → packages → bar', The 'bar' collection hasn't been filled with any content.
  At level 3, in directory path 'warning-for-non-root-project → packages → foo', The 'foo' compartment is barren.
  Back to the top level.
