Well, I thought you just said you had a Registry script already, or were
planning to create one.  It's trivial to call a template, and I don't
think I would call that amount of code a framework.  It could be this
simple:

     use vars qw($template);

     $template ||= Template->new({
         INCLUDE_PATH  => "/some/path/from/config"
     });

     # do your work here and put the results in $data
     my $data = {
         foo     => 'bar'
     };

     # use path_info here to pick a template if you like
     my $file = "/name/of/some/template.html";

     $r->content_type('text/html');
     $r->send_http_header;

     $template->process($file, $data)
         || die $template->error();

However, if you're keen on using Apache::Template, the way you're
supposed to do it is to subclass Template::Service::Apache and override
the params() method to do all of your processing.  See the
Apache::Template docs for an example.
