creloaded/oscommerce module

OK what I am looking for is a module that will help manage products in: Cre loaded/oscommerce/oscommerce max/zen cart/cubecart/..... all the major carts based on oscommerce. currently every product is counted as one product, even if the product has lots of attributes. What I am looking at having is a module that will help manage the quantity levels of the [login to view URL] I mean is when an atribute is out of stock, the atribute automatically become un-available. If there are 2 or 3 attributes for a product (e.g. size and color), the module will manage both levels for both attributes. So basically the module will manage levels for as many attributes a product has. The module should have a multi-product/single product management, so that it is easy to use and update stock levels upon setup. The module will have a good and easy to use admin area withing the admin of the shop. The product management side should also include an update per catagory/ manufacturer. Any other options or ideas will be welcomed. I am a c and c++ programmer, so the code needs to be clear and with lots of documentation. The module will be very easy to install on any cart and clear and easy documentation regarding the module.
