Jason,   I did not review this paper in detail but it appears relevant:

 Jisheng Cui, Nick de Klerk, Michael Abramson, Anthony Del Monaco,
Geza  Benke, Martine Dennekamp, Arthur W. Musk, and Malcolm Sim
Fractional Polynomials and Model Selection in Generalized Estimating
Equations Analysis, With an Application to a Longitudinal
Epidemiologic  Study in Australia Am. J. Epidemiol. 2009 169: 113-121;
doi:10.1093/aje/kwn292.

It seems the authors apply -fracpoly- in their analysis.
