The HQET/NRQCD Lagrangian is computed to order alpha/m^3. The computation is
performed using dimensional regularization to regulate the ultraviolet and
infrared divergences. The results are consistent with reparametrization
invariance to order 1/m^3. Some subtleties in the matching conditions for NRQCD
are discussed.
