Query: Light quark physics from lattice QCD   I review lattice calculations of quantities that involve light quarks,
including light quark masses, the vector form factor f_+(0) needed for
semileptonic kaon decays, and kaon mixing. Results for most of these quantities
are now available from multiple groups. Averages of these results are
presented, along with a discussion of the methodology behind the averaging
procedure. Recent progress in calculations of K->pi pi matrix elements is also
reviewed.
