I am not totally sure why we stopped including that, but I seem to
recall that we couldn't get all the mathematical notation to convert
to DocBook nicely. I also misdoubt that the math wouldn't scare off
the people who need it most.

I agree that a little bit of basic theory might go well as a chapter in
the tutorial ... but whether this is a good starting point is another
question.
