  Convert this description:
  
  functions is a master directory that encompasses 3 subdirectories: __tests__, plugins and src.
  At the top level, '__tests__' organizes tests across 2 separate child directories.
  Within directory hierarchy '__tests__ → __snapshots__', Inside '__snapshots__', you'll find it has nothing inside.
  In nested path '__tests__ / fixtures', Inside 'fixtures', you'll find it lacks any subdirectories.
  In the root directory, 'plugins' possesses 1 folders: gatsby-plugin-cool.
  In nested path 'plugins > gatsby-plugin-cool', 'gatsby-plugin-cool' groups 1 directory entries: src.
  In nested path 'plugins → gatsby-plugin-cool → src', 'src' encompasses 1 subdirectories that organize the source code.
  At level 4, in directory path 'plugins > gatsby-plugin-cool > src > api', 'api' groups 1 subfolders: gatsby-plugin-cool.
  In nested path 'plugins / gatsby-plugin-cool / src / api / gatsby-plugin-cool', 'gatsby-plugin-cool' is empty.
  Back to the top level.
  At the main level, 'src' retains 4 subdirectories that organize the source code.
  At level 2, in directory path 'src / api', 'api' keeps 7 different subdirectory elements.
  Within directory hierarchy 'src / api / a-directory', 'a-directory' remains unused.
  Within directory hierarchy 'src → api → config', 'config' awaits content.
  In nested path 'src / api / dir', The 'dir' collection is a vacant space.
  Within directory hierarchy 'src > api > gatsby-plugin-cool', Inside 'gatsby-plugin-cool', you'll find it is barren.
  In nested path 'src / api / ignore', 'ignore' hosts 1 subfolders: __tests__.
  At level 4, in directory path 'src → api → ignore → __tests__', '__tests__' is devoid of content.
  At level 3, in directory path 'src → api → named-wildcard', 'named-wildcard' is empty.
  In nested path 'src / api / users', 'users' keeps 1 contained folders: [userId].
  Within directory hierarchy 'src / api / users / [userId]', '[userId]' is blank.
  At level 2, in directory path 'src / images', The 'images' directory is barren.
  Within directory hierarchy 'src / lib', The 'lib' storage space awaits content.
  At level 2, in directory path 'src / pages', Inside 'pages', you'll find it has nothing inside.
