I hope that we can classify lesson 1 as a fait accompli and can move on to
lesson 2.
Be warned; lesson 2 is considerably more massive than lesson 1 - it
introduces many things. I believe we need at least a full week to cover it;
maybe more.
I haven't formatted it in html yet but I'm sending it as attachment to the
list in .txt and .doc formats.
Because it's so massive I, sort of, lost perspective - there may be
inconsistancies there. I hope the early readers will alert me to the
mistakes they notice and the late readers will benefit.
