prompt: Your task is to convert an English description into an ASCII tree format using this style:
  ```
  custom_resolve_dir
   +--testproj
   |   `--__snapshots__
   `--testproj2
       `--__snapshots__
  ```
  
  Convert this description:
  
  src is a base directory that includes 3 subdirectories: assets, bin and syntax_mapping.
  In the root directory, 'assets' groups 1 folders: build_assets.
  Within directory hierarchy 'assets / build_assets', 'build_assets' is blank.
  Back to the top level.
  In the root directory, 'bin' shelters 1 directories: bat.
  Within directory hierarchy 'bin → bat', Inside 'bat', you'll find it is devoid of content.
  Back to the top level.
  At the top level, 'syntax_mapping' incorporates 1 contained folders: builtins.
  At level 2, in directory path 'syntax_mapping → builtins', 'builtins' bundles 6 diverse directory entries.
  Within directory hierarchy 'syntax_mapping > builtins > bsd-family', Inside 'bsd-family', you'll find it is an empty container.
  At level 3, in directory path 'syntax_mapping → builtins → common', 'common' holds no subdirectories at the moment.
  At level 3, in directory path 'syntax_mapping > builtins > linux', 'linux' is empty.
  Within directory hierarchy 'syntax_mapping > builtins > macos', The 'macos' compartment holds no subdirectories at the moment.
  At level 3, in directory path 'syntax_mapping > builtins > unix-family', Inside 'unix-family', you'll find it has no content.
  At level 3, in directory path 'syntax_mapping → builtins → windows', The 'windows' directory has no content.
  Back to the top level.
  
  
  Provide your answer wrapped in <ascii_formatted> tags.
