10// Generator using the TPythia interface (via AliPythia)
11// to generate pp collisions.
12// Using SetNuclei() also nuclear modifications to the structure functions
13// can be taken into account. This makes, of course, only sense for the
14// generation of the products of hard processes (heavy flavor, jets ...)
