=head1 CAVEATS

On the server holding the PKG_ROOT, core/include/pkglist must be executed for
pkg upgrade and pkg push to work properly. It's recommended to execute it as
cronjob. A concept to execute it 'on demand' is planned.

=head1 EXAMPLES

=over

=item * B<pkg remote-update; pkg upgrade>

Get new stuff from the packages_root

=item * B<pkg local-update; pkg push>

Push local changes to the packages_root

=item * B<pkg eval exec_hook core post-update; pkg eval populate_collected core>

Update the core package after local changes.
(Yeah, this sucks. I'm working out a better way)
