Had to take a swipe 9^)

class String
   def wrap(wrap_col)
      retStr = self.dup
      start = 0
      while retStr[start,wrap_col].length >= wrap_col
         ws_pos = retStr[start,wrap_col].rindex(" ")
         break if ws_pos.nil?
         retStr[ws_pos+start] = "\n"
         start += ws_pos+1
      end
      retStr
   end
end


Cheers
