Oliver,

I have a minor issue with your patch set.  What is your rationale for
assuming if a zone is on more than one layer that it is a keepout zone?
I'm not sure that this would always be valid.  There is already a
"keepout" keyword in the list of board file keywords for just such an
occasion.  Wouldn't it be better to use the "keepout" keyword rather
than make assumptions about zones based on what layers they are on.
This is also not very human readable without some serious knowledge of
the pcb file parser.

Cheers,

Wayne
