“…Rather than presenting the solution and showing that it solves the low energy equations of type II superstring, we will describe some aspects of the art of solution-building. There are many excellent reviews of this area (see, for example, [45,46,47,48,49,50,51,52,53], other general reviews on black holes in string/M theories include [54,55,56]), so we shall be brief. The method of construction of various classical solutions, we will see, will throw light on the microscopic configurations corresponding to these solutions.…”
