Hi, Tobias.  Thanks for this.  It should help a lot.  I'll be quoting it quite 
often, I suspect ;-)

That's clearer.  I think it might be as well for me to put these definitions 
onto userbase.

Hmm - in that case, I'm not clear as to its purpose, unless it's as a last-
ditch emergency cover.

Understood.

This is where I'd clearly misunderstood.  I thought that toma was saying that 
~/.local/share/contacts was the cache, and std.vcf the real data, so I was 
expecting the cache flush to put it there.

I'll do that.  But if my KDE Addressbook is not there, where is it?  Am I 
causing problems by trying to have separate addressbooks?  Should I just be 
using Groups or tagging to achieve this?

Nearly there ;-)  A lot clearer, but still those few questions.
