  We introduce an iterated integral version of (generalized) log-sine integrals
(iterated log-sine integrals) and prove a relation between a multiple
polylogarithm and iterated log-sine integrals. We also give a new method for
obtaining relations among multiple zeta values, which uses iterated log-sine
integrals, and give alternative proofs of several known results related to
multiple zeta values and log-sine integrals.
