As for what type of a task this is, we have a script and a huge database
that has been worked on by some people to make a lot of this pretty
"automatic" to apply.

For the "odd" issues that Russell is worried about, those we can take as

Thomas and I are going to talk about this next week in Prague to see if
we can come up with a plan...
