One observes in numerical simulations that after an initial ``formation'' time, the produced partons are on shell, and their subsequent evolution can be studied using transport theory. At the initial formation time, a simple non-perturbative relation exists between the energy and number densities of the produced partons, and a scale determined by the saturated parton density in the nucleus.Latex, 6 pgs., uses sprocl.sty; invited talk at ISMD99, Brown Univ., august 11th-15th, 1999High Energy Physics - Phenomenologytext
