To use this engine, you may configure L<Dancer2> via C<config.yaml>:

    template:   "template_flute"

Or you may also change the rendering engine on a per-route basis by
setting it manually with C<set>:

    # code code code
    set template => 'template_flute';


This template engine allows you to use L<Template::Flute> in L<Dancer2>.
