  Some of the most arduous and error-prone aspects of precision resummed
calculations are related to the partonic hard process, having nothing to do
with the resummation. In particular, interfacing to parton-distribution
functions, combining various channels, and performing the phase space
integration can be limiting factors in completing calculations. Conveniently,
however, most of these tasks are already automated in many Monte Carlo
programs, such as MadGraph, Alpgen or Sherpa. In this paper, we show how such
programs can be used to produce distributions of partonic kinematics with
associated color structures representing the hard factor in a resummed
distribution. These distributions can then be used to weight convolutions of
jet, soft and beam functions producing a complete resummed calculation. In
fact, only around 1000 unweighted events are necessary to produce precise
distributions. A number of examples and checks are provided, including $e^+e^-$
two- and four-jet event shapes, $n$-jettiness and jet-mass related observables
at hadron colliders. Attached code can be used to modify MadGraph to export the
relevant leading-order hard functions and color structures for arbitrary
processes.
