prompt: Your task is to convert an English description into an ASCII tree format using this style:
  ```
  pre-compiled-headers
   +--groovy
   |   `--src
   |       +--hello
   |       |   +--cpp
   |       |   `--headers
   |       `--main
   |           `--cpp
   `--tests
  ```
  
  Convert this description:
  
  attestation is a master directory that features 10 subdirectories. Notable ones include api, artifact, auth among others.
  
  Let me break down the system for you:
  
  At the main level, Inside 'api', you'll find it is vacant.
  At the top level, 'artifact' encompasses 2 contained folders: digest, oci.
  In nested path 'artifact → digest', 'digest' has no content.
  At level 2, in directory path 'artifact > oci', Inside 'oci', you'll find it has yet to be populated.
  At the main level, 'auth' has yet to be populated.
  At the top level, The 'download' data structure has nothing inside.
  At the main level, Inside 'inspect', you'll find it has yet to be populated.
  At the top level, The 'io' repository hasn't been filled with any content.
  At the main level, 'test' organizes tests across 1 separate subdirectories.
  At level 2, in directory path 'test / data', 'data' is a vacant space.
  At the main level, 'trustedroot' has yet to be populated.
  At the main level, 'verification' incorporates 1 subdirectory elements: embed.
  At level 2, in directory path 'verification > embed', 'embed' groups 1 folders: tuf-repo.github.com.
  In nested path 'verification > embed > tuf-repo.github.com', The 'tuf-repo.github.com' folder is unpopulated.
  At the main level, The 'verify' collection remains unused.
