prompt: Your task is to convert the following English description into an ASCII tree format.
  
  fixtures is a head directory that assembles 9 subdirectories. Notable ones include exec-async, exec-async-node-10, exec-sync among others.
  
  Let me break down the organization for you:
  
  At the main level, Inside 'exec-async', you'll find it remains unused.
  At the main level, 'exec-async-node-10' awaits content.
  At the main level, The 'exec-sync' storage space is a vacant space.
  At the main level, Inside 'exec-sync-node-12', you'll find it appears to be unused.
  In the root directory, 'integration' houses 2 folders: async-to-generator, commonjs-transform.
  In nested path 'integration / async-to-generator', The 'async-to-generator' repository lacks any subdirectories.
  At level 2, in directory path 'integration / commonjs-transform', Inside 'commonjs-transform', you'll find it contains nothing at present.
  At the main level, 'source-maps' stores 4 several subdirectories.
  Within directory hierarchy 'source-maps → block', The 'block' repository stands empty.
  At level 2, in directory path 'source-maps > for-of', 'for-of' is empty.
  Within directory hierarchy 'source-maps > switch', 'switch' is currently empty.
  Within directory hierarchy 'source-maps > top-level', Inside 'top-level', you'll find it appears to be unused.
  Back to the top level.
  At the main level, 'transform-await' includes 3 subdirectories: mixed, only-using-await, switch.
  At level 2, in directory path 'transform-await → mixed', Inside 'mixed', you'll find it contains no subdirectories.
  Within directory hierarchy 'transform-await > only-using-await', The 'only-using-await' repository is a vacant space.
  At level 2, in directory path 'transform-await → switch', Inside 'switch', you'll find it is devoid of content.
  In the root directory, 'transform-sync' possesses 10 some contained folders.
  At level 2, in directory path 'transform-sync > bare-block', Inside 'bare-block', you'll find it hasn't been filled with any content.
  In nested path 'transform-sync → for-await-head', Inside 'for-await-head', you'll find it is devoid of content.
  In nested path 'transform-sync / for-head', 'for-head' has been left empty.
  At level 2, in directory path 'transform-sync / function-body', 'function-body' has no content.
  Within directory hierarchy 'transform-sync / if-body', 'if-body' has no folders inside.
  In nested path 'transform-sync > multiple-nested', 'multiple-nested' hasn't been filled with any content.
  In nested path 'transform-sync / multiple-same-level', 'multiple-same-level' sits empty.
  At level 2, in directory path 'transform-sync / named-evaluation', Inside 'named-evaluation', you'll find it holds no subdirectories at the moment.
  Within directory hierarchy 'transform-sync / static-block', Inside 'static-block', you'll find it is vacant.
  Within directory hierarchy 'transform-sync / switch', 'switch' is empty.
  In the root directory, 'transform-top-level' incorporates 8 various subdirectory elements.
  In nested path 'transform-top-level → await-or-not-preserved', The 'await-or-not-preserved' folder appears to be unused.
  Within directory hierarchy 'transform-top-level > hoisting', Inside 'hoisting', you'll find it is devoid of content.
  In nested path 'transform-top-level > hoisting-default-clas-anon', 'hoisting-default-clas-anon' has no folders inside.
  At level 2, in directory path 'transform-top-level / hoisting-default-class', Inside 'hoisting-default-class', you'll find it contains no subdirectories.
  At level 2, in directory path 'transform-top-level → hoisting-default-expr', The 'hoisting-default-expr' repository is a vacant space.
  At level 2, in directory path 'transform-top-level → hoisting-default-fn', Inside 'hoisting-default-fn', you'll find it is an empty container.
  Within directory hierarchy 'transform-top-level → hoisting-default-fn-anon', The 'hoisting-default-fn-anon' folder is empty.
  In nested path 'transform-top-level > hoisting-mutate-outer-class-binding', The 'hoisting-mutate-outer-class-binding' folder is blank.
  Back to the top level.
