We discuss general relativistic effects in the steady-state neutrino-driven``wind'' which may arise from nascent neutron stars. In particular, wegeneralize previous analytic estimates of the entropy per baryon $S$, the massoutflow rate $\dot M$, and the dynamical expansion time scale $\tau_{dyn}$. Weshow that $S$ increases and $\tau_{dyn}$ decreases with increasing values ofthe mass-to-radius ratio describing the supernova core. Both of these trendsindicate that a more compact core will lead to a higher number of neutrons periron peak seed nucleus. Such an enhancement in the neutron-to-seed ratio may berequired for successful r-process nucleosynthesis in neutrino-heated supernovaejecta.Comment: 10 pages including 3 figures, latex and aastex macros.
