This one really isn't a separate package, it's just a simple  
implementation that's used internally by OmniBrowser. You're welcome  
to use it for your own purposes, of course, but you might find it a  
bit spartan since it only implements what's needed for OmniBrowser. In  
particular, it uses an explicit Announcer, rather than having each  
object generate their own announcements. It doesn't bother with weak  
reference either, since the announcer will become garbage at the same  
time as its listeners anyway.
