CP Violation: The Past as Prologue
  CP violation is now measured by three numbers: \epsilon and {\epsilon{^{\prime} for the K^{0} system and sin2\beta for B^{0}. A future measurement of the analogue of {\epsilon{^{\prime} for the B system would end any possibility of a Superweaklike Theory. Future frontiers in CP violation are briefly discussed.
