Now, Ralf, don't you go scaring people away by suggesting that we
expect even more from them than just working with Axiom - that is hard
enough as it is! ;-)

Seriously, I think we can develop such documentation as we go. From my
point of view, doing this via the Axiom Wiki makes it very easy.

Bill Page.
