I've no idea what Peter worked on.

The API is there, but the client half of it (which is what you would
use) is not yet cleanly separated from the server. I've started doing
that, but it will take some time yet.

We'll end up with a libctdb library, which is what applications will
use. The code in common/ctdb_client.c is the basis for that library.

Cheers, Tridge
