Bugzilla::Template - Wrapper around the Template Toolkit Template object
  my $template = Bugzilla::Template->create;
  my $format = $template->get_format("foo/bar",
                                     scalar($cgi->param('format')),
                                     scalar($cgi->param('ctype')));
This is basically a wrapper so that the correct arguments get passed into the Template constructor.
It should not be used directly by scripts or modules - instead, use Bugzilla->instance->template to get an already created module.
