Clever or not, there are several comments on this ml that suggested 
merging was preferable to loading. Don't know who said it. In fact, I 
'loaded' my first upgrade test of Seaside/Magritte/Pier. It was 
disastrous. At least now I have the latest Seaside running ;-)

But, be that as it may, thanks for the help, I really appreciate it! 
You've been very helpful.
