Re: [Exim] What do you want in a book?

As you say, these are well documented elsewhere. Just a reference
would be enough.

I'm hoping that future developments will all be upwards-compatible for
a while now. My config (on the mail hub) is complicated enough for me
not to want another round of incompatible changes as happened from
Exim 2 to 3, good though Philip's conversion utility was.

I suggest not documenting anything internal at all. In normal
circumstances no-one, certainly not in the intended audience for the
book, should need to alter the code, or even read it. Philip has done
a splendid job of making sure it will compile on any known system.
