prompt: Your task is to convert the following English description into an ASCII tree format.
  
  preserve-modules-reaching-outside is a head directory that contains 2 subdirectories: _expected and src.
  At the main level, '_expected' stores 4 various directories.
  In nested path '_expected > amd', 'amd' features 1 subfolders: lib.
  In nested path '_expected > amd > lib', 'lib' is blank.
  At level 2, in directory path '_expected > cjs', 'cjs' holds 1 subdirectories: lib.
  At level 3, in directory path '_expected / cjs / lib', Inside 'lib', you'll find it has been left empty.
  In nested path '_expected → es', 'es' stores 1 directories: lib.
  Within directory hierarchy '_expected / es / lib', Inside 'lib', you'll find it lacks any subdirectories.
  Within directory hierarchy '_expected > system', 'system' bundles 1 subdirectory elements: lib.
  At level 3, in directory path '_expected > system > lib', Inside 'lib', you'll find it sits empty.
  Back to the top level.
  At the top level, 'src' has 1 subdirectories that organize the source code.
  At level 2, in directory path 'src → lib', Inside 'lib', you'll find it sits empty.
  Back to the top level.
