X-Cart forums - What is Feature Comparison?

Having just updated to 4.0.5 I was looking through, products.tpl where I noticed:-

Code:

        {if $active_modules.Feature_Comparison ne ''}

        <TD width="15" valign="top" onclick="javascript: fe_check_td({$products[product].productid});">{if $products[product].fclassid > 0}<INPUT type="checkbox" id="pid_{$products[product].productid}" value="Y" onclick="javascript: fe_check_products({$products[product].productid});">{/if}</TD>

        {/if}

What is Featured Comparison, I know what it does, but how come there is nothing in modules folder where it is supposidly calling information from and I have not seen anything in the Admin side. Is this a future feature and they are just implementing parts in place?
