Everyone is so used to garbage documentation, that they go googling instead, but OpenBSD docs are in fact very good.

Not that I disagree, but in this case that is really not the point of what I quoted.

The point is that often, before you reach some level of understanding, you can read the docs 5 times and not find the answers you are looking for, even though they are there! As soon as you reach the right level of understanding, then the docs are perfect!
