Don't forget, also, that "need to know" may be great in wartime, to 
prevent secrets leaking, but it's not good for learning. And certainly, 
I find the best way of learning is to have stuff aimed at what I'm 
trying to do, but is full of snippets of bits of information that go 
that little bit deeper. That way, I have the incentive to study the 
teaching material, but it's actually teaching me at a deeper level than 
I need - so I can then progress to the next level with greater ease. So 
probably this information would work well as a footnote in a user 
tutorial - when it talks superficially about engravers it could point 
them at this somewhat deeper explanation of what an engraver actually is.
