-  # Move the user *src* to *dst* within the Agendav database. This
-  # should "rename" him in _every_ table where he is referenced.
-  #
-  # This can fail if *dst* already exists before the move. It should
-  # also be an error if the destination domain doesn't exist. But
-  # Agendav doesn't know about domains, so we let that slide.
-  #
-  # If the source user doesn't exist, we do our best. AgenDAV has a
-  # "shares" table that isn't keyed on the username, but rather the
-  # principal URL. And its "prefs" table doesn't contain entries for
-  # users who have default preferences. As a result, we may need to
-  # perform some find/replaces in the "shares" table even if no
-  # corresponding user exists in the "prefs" table (which is how we
-  # tell if a user exists in AgenDAV). Thus it's not a fatal error if
-  # the *src* user doesn't exist.
-  #
-  # @param src [User] the source user to be moved.

-      # here. That's because in the usual legitimate use case, the
-      # calendar URL will change when a user moves. This will ALSO

-      # "user%40example.com", but screw those people.
