description:
* Add two new (experimental) targets:

        buildworld      Builds a distribution into DESTDIR as per
                        "make distribution", except that DESTDIR
                        *must* be defined and *must not* be "" or "/".

        installworld    Copies (using distrib/sets/maketars -i ...) from
                        ${DESTDIR} to ${INSTALLWORLDDIR} (defaults == `/'),
                        and then runs "postinstall-check" against
                        ${INSTALLWORLDDIR}.
                        If ${INSTALLWORLDDIR} == "/", ensure that
                        `uname -s` == "NetBSD" and `uname -m` == ${MACHINE},
                        to prevent nasty accidents...

* Tweak some comments
