Query: Inclusive semileptonic decays of the B meson   This talk is a short review on the theoretical issues and uncertainties in
the calculation of partial decay rates in inclusive B decays. The main emphasis
is on charmless semileptonic decays, the B -> X(s) gamma photon spectrum, and
the extraction of Vub using model-independent methods.
