I am just wondering if ditto for zen-cart ecommerce is included in the fantastico scripts provided by hosting companies.

Here's a current list of scripts installed by Fantastico:

Doesn't make any mention of ditto for Zen Cart, which probably means they just do a plain install of it :)

yes, ditto is not mentioned here that's why I decided to raise up this question here
