Registering COM objects via command line build

I'm trying to integrate wyUpdate with CruiseControl.net and I need to have several DLL files registered as COM objects. Is there anything I can add/change in my newversions.xml that I generate to indicate that said file needs to be treated as a COM dll and register it? Or am I stuck running some batch scripts before/after the updates?

Sorry, you're right. This is missing from the building from commandline xml spec. We'll add that to the bugfix release (2.6.8) coming Friday next week along with the ability to add update actions (starting / stopping windows services) via the xml file.

Sorry for the oversight.
