From 974a8c152bf7c9a4a5ce3c45808af65657c2ff1f Mon Sep 17 00:00:00 2001
From: Boris Kolpackov <boris@codesynthesis.com>
Date: Thu, 8 Feb 2018 12:44:06 +0200
Subject: Add --for|-f <operation> option to pkg-update and pkg-build

This allows executing build2 -for-X operations (e.g., update-for-install
or update-for-test) in order to minimize the amount of stuff to be updated.
