<!-- This view demonstrates how to use the conditional branches with
     djula. If the vaule 'stock' is greater than 0, it will print the
     value (next to 'Stock:'). If the stock is 0 (or less), the page
     will say 'This is no stock', instead.

     The variable/value, 'stock' is passed to the view from the controller
     in /src/web.lisp.
