Product description on checkout confirmation page

Hi

I am looking to display the product description on the checkout confirmation page
but I am not sure which page I would need to edit to show this.

Any help we would great.

I think it should be includes/classes/order.php.

All I need to do is put the description directly below the title.

Thanks

I am also looking to display the description on the account_history_info page when a customer checks their order.

I have managed to get the product description added to the account
history page by editing the order.php page and the account_history_info_default.php template file.

I have tried to edit order.php and tpl_check_out_confirmation_default.php to display the description on the order confirmation but this is not working.

I was able to add the description to the check confirmation page by editing includes/classes/shopping_cart.php
and tpl_check_out_confirmation_default.php bye editing the query.
