  We study U(N) SQCD with N_f <= N flavors of quarks and antiquarks by
engineering it with a configuration of fractional D3-branes on a C^3 / Z_2 x
Z_2 orbifold. In particular we show how the moduli space of the gauge theory
naturally emerges from the classical geometry produced by the D3-branes, and
how the non-perturbatively generated superpotential is recovered from
geometrical data.
