## Configure the job to be an MC production job
j.application      = AthenaMC()

## Define the Athena release to use

## Define some job parameters from which the output files will be named

## Define the output dataset name

## Define which transform to use

## Configure the job such that it is sent to the grid

## Define where the job should run

## Define the storage location for the output dataset
