Thanks for the confirmation. I should have time to work on this over the next 
days. I haven't looked in detail yet, but I get the feeling there is more to it 
than changing a few variables :-). Beyond code, do you have a mental checklist 
of the items that will need adjusted? E.g. docs, examples, tests, etc?
