Sorry, wrong URL.  It should have been:

https://docs.google.com/document/d/1ft26lUQyuSpiu6VleP70_npaWdRfXFoNnB8JYnykNTg

And Andreas has pointed out there are a few places where it may be
slightly out of date.  So it's good for checking the general idea, but
some of the details may not be quite right.  In particular, we are now
using CTS (Ciphertext Stealing) mode for directory entries, instead of
the weird thing described in the design doc.
