As is by now well known, Tu proved in 1998 that the C*-algebras coming from amenable groupoids satisfy the so-called UCT (universal coefficient theorem). Unfortunately, I don't speak french and I've only found this result in french.

**Question:** does anyone happen to know of any account of the proof that is written in English?

Tu's original paper is fairly long, and hence would require a lot of work to read for a non-speaker. Even talks available online, or particular cases (such as the same for amenable groups) would be helpful and very much appreciated.
