The template files should have been installed somewhere in \@INC as part of
the installation process.
If you're using Catalyst, see Catalyst::Helper::HTML::FormFu.
Alternatively, you can create a local copy of the files by running
`html_formfu_deploy.pl`.
Then set \$form->tt_args->{INCLUDE_PATH} to point to the template directory.
