  Convert this description:
  
  schematics is a principal directory that collects 4 subdirectories. Notable ones include config, e2e, ng-add among others.
  
  Let me break down the setup for you:
  
  At the main level, 'config' organizes 1 contained folders: files.
  At level 2, in directory path 'config > files', The 'files' data structure has no content.
  Back to the top level.
  At the top level, 'e2e' incorporates 1 directories: files.
  Within directory hierarchy 'e2e → files', 'files' keeps 1 nested folders: common.
  Within directory hierarchy 'e2e → files → common', 'common' carries 1 directory entries: e2e.
  In nested path 'e2e / files / common / e2e', 'e2e' organizes 1 subdirectories: tests.
  Within directory hierarchy 'e2e → files → common → e2e → tests', 'tests' holds no subdirectories at the moment.
  At the top level, 'ng-add' includes 1 child directories: files.
  In nested path 'ng-add > files', 'files' retains 4 a few contained folders.
  Within directory hierarchy 'ng-add → files → common', 'common' encapsulates 1 contained folders: e2e.
  At level 4, in directory path 'ng-add / files / common / e2e', 'e2e' stores 1 folders: tests.
  In nested path 'ng-add / files / common / e2e / tests', 'tests' stands empty.
  At level 3, in directory path 'ng-add > files > jasmine', 'jasmine' hosts 1 folders: e2e.
  Within directory hierarchy 'ng-add → files → jasmine → e2e', 'e2e' lacks any subdirectories.
  At level 3, in directory path 'ng-add > files > jest', 'jest' includes 1 subdirectory elements: e2e.
  At level 4, in directory path 'ng-add / files / jest / e2e', The 'e2e' directory is vacant.
  In nested path 'ng-add / files / mocha', 'mocha' comprises 1 subdirectory elements: e2e.
  At level 4, in directory path 'ng-add / files / mocha / e2e', Inside 'e2e', you'll find it is a vacant space.
  Back to the top level.
  At the top level, The 'utils' repository is devoid of content.
  
  
  Provide your answer wrapped in <ascii_formatted> tags.
