  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
