Thanks Ben, and Cyril.

I liked Mariano's approach, and I will play with that. However, I think the suggestion about using Moose may be exactly what I need.

I have been playing with Mathematica a lot lately, and I really appreciated the fact that you got the kitchen sink with it.

What I was wondering - taking Cyril's comment into account - is whether there is an argument for producing a kitchen sink image which contains the stable versions of all the key tools.  Obviously, that requires some discussion/analysis of what the key tools are, but it shouldn't be impossible to do.

In the meantime, I am off to play with Moose :-)

Cheers

Andy
