  The chiral limit of finite-volume QCD is the $\epsilon$-regime of the theory.
We discuss how this regime can be used for determining low-energy observables
of QCD by means of comparisons between lattice simulations and quenched and
unquenched chiral perturbation theory. The quenched theory suffers in the
$\epsilon$-regime from ``quenched finite volume logs'', the finite-volume
analogs of quenched chiral logs.
