Seen file question(s) with cvt_cyrusdb

[Bill Ryder]

And as I think about it I guess that makes sense because cvt_cyrusdb 
uses the normal database stuff - so it doesn't actually clear out the 
destination database before it starts. It assumes it's supposed to 
update the database.

So changed records get replaced and new records get added but existing 
records remain unchanged.

Sorry for talking to myself!
