  Convert this description:
  
  groovy is a principal directory that houses 3 subdirectories: buildSrc, core and util.
  At the main level, 'buildSrc' groups 1 nested folders: src.
  Within directory hierarchy 'buildSrc → src', The 'src' section contains 1 folders for code organization.
  At level 3, in directory path 'buildSrc / src / main', 'main' includes 1 directory entries: groovy.
  Within directory hierarchy 'buildSrc → src → main → groovy', The 'groovy' repository has yet to be populated.
  At the main level, 'core' holds 1 contained folders: src.
  In nested path 'core / src', The 'src' folder comprises 1 folders for code organization.
  Within directory hierarchy 'core → src → test', 'test' shelters 1 test-related directories.
  At level 4, in directory path 'core → src → test → swift', The 'swift' compartment is a vacant space.
  Back to the top level.
  At the main level, 'util' includes 1 directory entries: src.
  Within directory hierarchy 'util > src', 'src' carries 1 subdirectories that organize the source code.
  Within directory hierarchy 'util → src → test', 'test' houses 1 folders for testing purposes.
  At level 4, in directory path 'util / src / test / swift', The 'swift' collection contains nothing at present.
