Four candidate protostars have been identified, with luminosities of 1-5×'l04L⊙ and masses of 10-20M⊙, in a magnitude-limited near-infrared survey of the 30-Dor complex. Each is associated with a dense knot in the nebular arcs. We suggest that both the knots and the associated star formation result from the compression of interacting arcs of mass-loss winds from hot massive stars in the central cluster and other nearby clusters. This mode of star formation appears to be highly efficient. In the 30-Dor region there is a clear spatial separation of the young blue stars and older red stars, strengthening the evidence for a multiple starburst in the region.
