Roots of polynomial equations with complex coefficients

HI MathGroup,

Does anybody know the algorithm Mathematica uses when NSolve is dealing with
polynomial equations with complex coefficients? Is it the Jenkins-Traub method?
I'm willing to write a Fortran code to compute polynomial roots of a very
complicated equation that Mathematica apparently cannot handle with NSolve or
FindRoot. I ultimately would like to see the C code behind NSolve, but I wonder
it is kept as a secret by Wolfram.

Thanks,
Luiz
