To avoid clutter, the initial theme_ substring is omitted from all themeable functions listed below.
WARNING: at the moment, this is only the list of themeable functions defined by product.module. It will be expanded as soon as I read the code of the other modules, so it is by no means exhaustive (yet).
|Render product node. Also used for pseudo-products
|Format product price info
|Default view for q=product. Might not remain stable according to comments
|Used in theme_node_product to apply product-type specific themes
