A complete supersymmetric SO(10) model is constructed, which is the most
general consistent with certain R, discrete, and U(1) flavor symmetries.
The desired vacuum of the theory has vevs which lie in particular directions of
group space. This leads to both doublet triplet splitting and to the generation
of just four operators for charged fermion masses. The model illustrates how
many features of superunification become related in the context of a complete
theory. The features discussed here include: the weak mixing angle prediction,
the doublet-triplet splitting problem, proton decay, the generation of the
μ parameter, neutrino masses and the generation of the operators which lead
to charged fermion mass predictions.Comment: 18 page
