  ri String#chomp
----------------------------------------------------------- String#chomp
      str.chomp(separator=$/)   => new_str
------------------------------------------------------------------------
      Returns a new String with the given record separator removed from
      the end of str (if present). If $/ has not been changed from the
      default Ruby record separator, then chomp also removes carriage
      return characters (that is it will remove \n, \r, and \r\n).

         "hello".chomp            #=> "hello"
         "hello\n".chomp          #=> "hello"
         "hello\r\n".chomp        #=> "hello"
         "hello\n\r".chomp        #=> "hello\n"
         "hello\r".chomp          #=> "hello"
         "hello \n there".chomp   #=> "hello \n there"
         "hello".chomp("llo")     #=> "he"
