    my @flags = GPTAPI::QueryBundleDef(bundledef => "client.gpt-bundle.xml",
                                       key       => "Flags");
    if ( grep /NoDeps/, @flags )
    {
        print "This bundle does not include dependent packages not";
        print "explicitly listed in IncludedPkgs\n";
    }

   print "This bundle only includes the following packages:\n";
   for my $pkg  (GPTAPI::QueryBundleDef(bundledef => "client.gpt-bundle.xml",
                                        key       => "IncludedPkgs"))
   {
       my ($name, $flavor, $type) = $pkg =~ m!(.+)-([^_]+)_(.+)!;
