  In the near future, we will have the first significant experimental
measurements of CP violation in B decays. These measurements will easily test
crucial questions such as whether the Standard Model Kobayashi-Maskawa phase
plays a dominant role in CP violation or whether CP is an approximate symmetry
in nature. We explain the different types of CP violation in B decays, and the
usefulness of measuring them. We use the same formalism to describe the epsilon
and epsilon(prime) parameters of the neutral K system and to explain the terms
direct and indirect CP violation. We present the Standard Model predictions for
the various asymmetries. We argue that certain CP asymmetries in B decays are
subject to a very clean theoretical interpretation in terms of fundamental
Lagrangian parameters. Within the Standard Model, these asymmetries will
provide very accurate measurements of the CKM parameters. In case that
deviations from the Standard Model predictions will be found, there is enough
information to understand the nature of New Physics that is required to explain
them. We demonstrate this statement by analyzing the impact of various
Supersymmetric flavor models on CP violation.
