First, let me pass on my thanks for org-mode.  It seems to be a great way to
manage tasks using Emacs.

How can I get a list of completed tasks and their completion dates?  I've
combed the Info docs and the web and could not find how to do it.  I would
like something like C-c a a l, but that only shows me the completed tasks
for each day.  Is there anyway to get a nice sorted list like:

CategoryA:   DONE   Add xyz to the fobnitz   <2008-06-10>
CategoryB:   DONE   Fix foo in bar program   <2008-06-12>

Any ideas?  I'm using Org-mode version 4.67c, which is included with GNU
Emacs 22.2.1.  Thanks very much.
