 Shopping carts are stored as Perl hashes in session files that you'll find in 
each catalog's /session directory. To access these hashes directly from 
within a template, the best way is to use some embedded perl in your HTML and 
the objects that Interchange exposes, like this:

 <h2>Blah blah blah...</h2>
 [perl]
	my $current_cart = $Carts->{main};
	my $quantity = $current_cart->[0]->{quantity};
        $Scratch->{foo} = $quantity;
        return;
 [/perl]
 <p>Quantity of first item in cart: [scratch foo]</p>

 There's more interfaces documented here:

 Interchange already comes with an Authorize.Net module that you'll find in 
the ~interch/lib/Vend/Payment directory. There's modules for other payment 
processors there, too.
