  The interpretation of experimental measurements at the LHC requires accurate
theoretical predictions for exclusive observables, and in particular the
summation of soft and collinear radiation to all orders in perturbation theory.
We report on recent progress towards the automated calculation of multi-parton
LHC cross sections at next-to-leading order in QCD, including the summation of
next-to-leading logarithmic corrections through the combination with parton
showers.
