Theoretical Overview of CP Violation in B-Meson Decay

After a brief look at CP violation in kaon decays, a short overview of CP violation in the $B$-meson system and of strategies to determine the angles of the unitarity triangles of the CKM matrix is given. Both general aspects and some recent developments are discussed, including $B_c^\pm\to D^\pm_s D$ and $B\to\pi K$ decays, as well as the $B_d\to\pi^+\pi^-$, $B_s\to K^+K^-$ system.
