Here is an updated patch with a new manual chapter.  It has the
necessary struct definitions that the client should include, and step
by step instructions for what to do.  I'd appreciate if someone could
review the writing and my texinfo, though.  I mentioned the manual
chapter in the NEWS entry, since the explanation of how it works is
long.

What else needs to be addressed?
