prompt: Your task is to convert the following English description into an ASCII tree format.
  
  1.7.0 is a source directory that includes 2 subdirectories: include and lib.
  In the root directory, 'include' encompasses 1 subfolders: gtest.
  In nested path 'include → gtest', 'gtest' features 1 test-related directories.
  Within directory hierarchy 'include → gtest → internal', The 'internal' data structure lacks any subdirectories.
  At the main level, 'lib' groups 7 subdirectories that organize the source code.
  At level 2, in directory path 'lib > cygwin', The 'cygwin' compartment appears to be unused.
  In nested path 'lib / linux', The 'linux' container is barren.
  Within directory hierarchy 'lib / mingw', 'mingw' is devoid of content.
  In nested path 'lib → osx', 'osx' is a vacant space.
  Within directory hierarchy 'lib > vs2010', The 'vs2010' collection sits empty.
  At level 2, in directory path 'lib → vs2013', 'vs2013' has no folders inside.
  Within directory hierarchy 'lib > vs2015', 'vs2015' is empty.
