Can someone remind me once again, when rebuilding all of my ports, what
is the trick for avoiding the options dialogs?  I'd like to have this
run largely unattended. I seem to recall someone describing a method to
go through all of them upfront, rather than having the build process
interrupted each time a port wants that input.

I know that portupgrade has a batch build option, but unless I'm
mistaken, that skips any ports that need interaction to build.
