Hiro,
I'm happy to respond to you, but first I'd like to make clear that I'm
not trying to talk you out of anything. If there is a better way to
manage ports, or even just a different approach, I'm all for it. I
don't think portmaster is a "one size fits all" tool, and I'm not
trying to make it one.

The man page has a good overview, I have documented it relatively
thoroughly, and I keep it up to date. You can either install the port,
or do:
nroff -man /usr/ports/ports-mgmt/portmaster/files/portmaster.8 | more
Of course, you can always "use the source luke." :) I won't claim that
it's as well documented as it probably should be, but being written in
/bin/sh it's not that hard to figure out what's going on.

It's /var/db/pkg/*/+IGNOREME, but yeah, that'd work for something you
don't want portmaster (or portupgrade for that matter) to mess with.

I should probably point out that this is the worst case scenario,
since by definition portmaster -a has to evaluate each installed port.
The vast majority of the time spent doing that though is in 'make -V
PORTVERSION'.
The benefit comes when you actually start building stuff and because
all the information about the up to date ports is cached, it won't
have to be reevaluated.

Fair enough.
I think it's useful and healthy to discuss where both the various
tools, and the infrastructure can be improved.
