Auto-Generated Contributor Lists [Patch]

I've added code using the Template Toolkit to automatically generate the
"Acknowledgements" list from the <link rel="author"> tags we've been
adding to the tests. The patch is attached. If someone could review,
that would be great.. I'm particularly unsure about this part

+# Template Engine
+
+my $libroot = $INC{'indexer.pm'};
+$libroot =~ s/indexer.pm//;
+my $tt = Template->new({ INCLUDE_PATH => $libroot . 'templates/' })
+           || die "$Template::ERROR\n";
