Just add another node to your DAG, and make that node a child of the final 
node or nodes that you already have.  Then the "notification" node can 
just run a script that emails the notification to whoever you want.  (Note 
that this won't work quite the same as the normal Condor notification, 
because the email will only be sent if the DAG succeeds.)  (We've actually 
talked about, but not yet implemented, an option to have a special 
"cleanup" node that gets run at the end if the DAG fails.  That would make 
it possible to have multiple notifications sent if the DAG fails.)

Hopefully the above note makes sense...

Hmm -- maybe that means we need to clarify that part of the manual.  I 
know it was one of the more difficult parts to write.  Any suggestions on 
how to make this clearer?
