I think you're thinking of portmaster, mergemaster doesn't touch ports
stuff. What portmaster does when it updates +CONTENTS files is to
update a temp copy first, then move the updated file into place after
it's done. Not sure what portupgrade does.
In terms of easily recreating them, I can't think of a way to do that
reliably other than to build the ports again. portmaster relies
heavily on the data in +CONTENTS, and it couldn't even rebuild your
ports in place without them since it wouldn't be able to find the ORIGIN.
What you could do with portmaster is to pick a high level leaf port
with a lot of dependencies (something like firefox) and do 'portmaster
-aft /usr/ports/www/firefox' (make sure you specify the directory in
/usr/ports, not the pkg directory).
hth,
Doug
