You don't mention the pickle suite. Are you aware of this?

David, this page isn't advertised very well. There are links only from the
class_ reference section and from the acknowledgement page. I think it would be
good to (re?)introduce a link at the front page. Later we could do something
like this:
- Suites
      - Indexing
      - Pickling
