prompt: Your task is to convert an English description into an ASCII tree format using this style:
  ```
  shared-dependency-no-side-effect
   +--_expected
   |   +--amd
   |   +--cjs
   |   +--es
   |   `--system
   `--shared
  ```
  
  Convert this description:
  
  --ignore is a head directory that comprises 2 subdirectories: in-files and out-files.
  At the top level, 'in-files' bundles 1 folders: src.
  At level 2, in directory path 'in-files > src', 'src' bundles 2 subdirectories that organize the source code.
  In nested path 'in-files > src > bar', 'bar' is vacant.
  Within directory hierarchy 'in-files → src → foo', 'foo' is empty.
  Back to the top level.
  At the top level, 'out-files' retains 1 subdirectories: lib.
  At level 2, in directory path 'out-files > lib', 'lib' shelters 1 subdirectories that organize the source code.
  In nested path 'out-files > lib > bar', The 'bar' storage space is barren.
