There should be an edition for non US users. I have discovered that some of the exercises are not possible here in the UK as there are two versions of the programme. One for the US and one for everyone else. There is only one book so it covers the US version. As a reference of what's available it is quite good but I'm looking for a book which covers what is available to UK users of the software. I was very reluctant to give any more than two stars but I thought one was a bit too mean.
