  To better understand Wolf-Rayet stars as progenitors of gamma-ray bursts, an
understanding of the effect metallicity has on Wolf-Rayet mass loss is needed.
Using simple analytic models, we study the Mdot - Z relation of a WN star and
compare the results to similar models. We find that Mdot roughly follows a
power law in Z with index 0.88 from -2.5 < log Z/Z_sun < -1 and appears to
flatten by log Z/Z_sun ~ -0.5.
