   |   `--src
   |       +--hello
   |       |   +--cpp
   |       |   `--headers

   `--tests
  ```
  
  Convert this description:
  
  call_caching1 is a primary directory that gathers 2 subdirectories: __snapshots__ and lib.
  At the main level, Inside '__snapshots__', you'll find it is empty.
  At the top level, 'lib' contains 1 subdirectories that organize the source code.
  At level 2, in directory path 'lib / __snapshots__', Inside '__snapshots__', you'll find it has yet to be populated.
  Back to the top level.
