Karin sent us a link to a WIKI page for our code review. Unfortunately, links to the content from that page don't work because Alastair is no longer a user. A link to the documentation is to a tarred-and-gzipped archive containing Word and Excel files, which is a bit of a showstopper. Asked Karin to post plain text versions of the documentation and link them from the WIKI page, so we can all see what we're supposed to see.
