Cool, thanks for reviewing it.

The PRODUCT override came with the need of using Mamona with a common
machine but for different purposes. Instead of maintaining different
trees, we decided to create the concept of a product and define there
the preferred version and providers for different packages.

With this we could work with both "products" at the same tree, just
using the overrides at the product file to define the best behavior
for that machine.

One single example we had was regarding the legal check phase of a
product, that we knew that some version of some packages was already
approved, when at the same moment newer versions weren't (so with
another product that we just started we could use the newer version,
but for the older one we had keep the same old version, because was
close to be finished).

Ok, will change that. Will also change the commit message to explain
that the idea came from mamona.

Thanks,
