Can you clarify what it is that you don't understand, or what it is that you need to know? Because the part you quoted (which I do recognize, and have made use of myself in the past) seems perfectly straightforward and understandable to me, and you haven't provided any context to indicate what your problem is or what it is that you don't understand. -- The Wanderer The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself. Therefore all progress depends on the unreasonable man. -- George Bernard Shaw
