This needs fixing.

I like it because if you happen to have a configuration you would
like to use again, you can capture the output and make it your
fstab, + or - automount adjustments.

But what if you leave out ALL the stuff after -x. Isn't it redundant with
the +d switch? (That's not a Socratic question: I don't know.)
Anyway, I found the lsof FAQ by make extract in the port. I quess I am not
too good at reading Makefiles because I don't see why it isn't copied to
/usr/local/share/lsof with the README and whatnot.
