You're probably correct.  Technically, I think the To* modules should
be the last things in GLOBAL_PIPELINE and the out qrunner's own
internal pipeline should call AfterDelivery and Acknowledge.  But in
practice I doubt it matters.

It's optional!  That's actually one of the cool things about Python;
the trailing element in a list (or dict or tuple) can have a comma
after it.  Makes rearranging the list elements so much nicer for
cut-n-paste.  The one exception is for tuples with only one element:
they /must/ have the trailing comma:

   tupleone = (1,)

because (1) is syntactically ambiguous.

Are you looking at the current cvs?  The Personalize.py module is gone
now, SMTPDirect.py having subsumed all its functionality for
performance reasons.
