just updated the NetBSD package.  It'll show up on ftp.netbsd.org in a day
or so.

well, a logical AND is good for "do I have silk screen on my pads
(detected by soldermask relief)" questions.  A logical xor is good for
finding where you have soldermask relief and no copper.  I'm sure others
could be useful somewhere.  Actually, if you have these logical operations
available to your coming scheme interpreter, you could do various DRC
checks.
