An eclipse light curve analysis code based on the logistics of the Wilson-
Devinney approach has been developed to account for the effects of radiation
pressure due to the mutual irradiation of the components of close binary systems. The
radiative forces exerted by luminous, hot stars may cause geometric deformations
of stellar surfaces and influence the binary configuration and evolution.
