Right. I mis-spoke somewhat when I said 'processing ceases.' What I meant was
'processing ceases for that pass through the router.' IOW, once it finds a
match, SIMS immediately applies whatever router line it has matched and sends
the address back to the top of the router without looking at subsequent lines.
Sorry for the confusion.

The angle brackets are also used indicate an address for which 'foreign
aliasing' is being defined. In that case the entire address, including the
domain part, needs to be enclosed in angle brackets. There's a section on
'Foreign Aliasing' on the Router page in the SIMS docs that describes this.

Yes. And the 'local' and 'domain' parts of an address can get rather
complicated, as described in the Router page of the SIMS docs.

If anyone has created a graphical flow chart for it, I'm not aware of it.
Might be an interesting exercise... ;-)

I'm not sure -- I've never really looked at CGP, as my operation is far to
small to consider using it.
