prompt: Your task is to convert an English description into an ASCII tree format using this style:
  ```
  fonts
   +--Inter
   |   `--static
   +--Space_Grotesk
   |   `--static
   `--Space_Mono
  ```
  
  Convert this description:
  
  3rd-party-lib is a central directory that features 2 subdirectories: boost_1_55_0 and util.
  At the main level, 'boost_1_55_0' groups 1 subdirectory elements: boost.
  Within directory hierarchy 'boost_1_55_0 > boost', 'boost' remains unused.
  At the top level, 'util' holds 1 directory entries: src.
  At level 2, in directory path 'util → src', 'src' shelters 1 subdirectories that organize the source code.
  Within directory hierarchy 'util > src > util', 'util' holds 2 subdirectories: cpp, headers.
  In nested path 'util / src / util / cpp', Inside 'cpp', you'll find it is unpopulated.
  In nested path 'util > src > util > headers', Inside 'headers', you'll find it has nothing inside.
  Back to the top level.
