hi chris. it's a fair point. but i suppose the other side is that this way all man pages would begin with a list of important points. almost like sticking CAVEATS at page top. i think the text is written in a logical order, to be honest. if all the stuff before the "watch out!" text is not needed, then i guess a CAVEATS might be better. but it reads like it;s all useful. (but to be fair, i really am not familiar with this stuff) jmc
