prompt: Your task is to convert the following English description into an ASCII tree format.
  
  fixtures is a core directory that organizes 3 subdirectories: multiple, nested and single.
  At the top level, 'multiple' stores 1 subfolders: app.
  Within directory hierarchy 'multiple / app', Within 'app', you'll find 1 directory entries for code structure.
  Within directory hierarchy 'multiple / app / [lang]', '[lang]' possesses 1 directory entries: [region].
  Within directory hierarchy 'multiple / app / [lang] / [region]', '[region]' is devoid of content.
  Back to the top level.
  In the root directory, 'nested' shelters 1 directory entries: app.
  In nested path 'nested / app', Within 'app', you'll find 1 folders for code structure.
  In nested path 'nested / app / [lang]', '[lang]' bundles 1 nested folders: blog.
  In nested path 'nested / app / [lang] / blog', 'blog' features 1 folders: [slug].
  In nested path 'nested → app → [lang] → blog → [slug]', Inside '[slug]', you'll find it is unpopulated.
  Back to the top level.
  At the main level, 'single' encapsulates 1 subdirectories: app.
  At level 2, in directory path 'single / app', 'app' holds 1 subdirectories that organize the source code.
  Within directory hierarchy 'single > app > [lang]', The '[lang]' container remains unused.
