  12.  Example:
  13.  
  14.   File.basename('/javascripts/bin.js',2) // => bin.js
  15.   File.dirname('/javascripts/bin.js',2) // => /javascripts
  16.   File.path('/javascripts/bin.js',1) // => /javascripts/bin.js
  17.   File.platform('/javascripts/bin.js',2) // => 2
  18.   File.platformString('/javascripts/bin.js',2) // => Macintosh
  19.   File.platformString('/javascripts/bin.js',1) // => Windows
  20.   File.platformString('/javascripts/bin.js',2) // => Macintosh
  21.   File.platformString('/javascripts/bin.js',3) // => UNIX
  22.   File.platformString('/javascripts/bin.js',4) // => undefined
