=head1 DESCRIPTION

This class is an interface between Dancer's template engine abstraction layer
and the L<Text::Xslate> module.

In order to use this engine, use the template setting:

    template: xslate

This can be done in your config.yml file or directly in your app code with the
B<set> keyword.

You can configure L<Text::Xslate> :

    template: xslate
    engines:
      xslate:
        cache_dir  => "/www/../xslate_cache",
        cache      => 1,
        module =>
          - Text::Xslate::Bridge::TT2 # to keep partial compatibility
