My comment stands. Are you sure you understand what I said? Perhaps given the tone of the discussion you pointed towards you did not. I am sure that I need not point out what the word Sufficient means— if you percieved it to mean “every line” or some other such nonsense let me re-assure you that, that would be wrong. What I meant is precisely what I said—I said change the emphasis, I didn't say change the amount. If a program needs no comments then so be it, if not then adjust accordingly. As I have pointed out before, one of my techniques in taking over projects is to create a copy of the source without comments, since initially I prefer to see what was written, not what someone thought was written or something that was true once apon a time or any of the other problems that documentation is prone to.
