  CBS is a new program for binary system light curve analysis, it generates
synthetic light curves for a binary system, accounting for eclipses, tidal
distortion, limb darkening, gravity darkening and reflection; it is also
possible to compute the light contribution and eclipses of an accretion disk.
The bolometric light curve is generated, as well as curves for the U,B,V,R,I
colour bands. In the following we give a brief description of the first version
of the program and show some preliminary results.
