   6 # This script is used when using Galago on a cluster of machines.  Galago will tell
   7 # the job scheduler (either its own SSH scheduler, or another one like Grid Engine or
   8 # Condor) to execute the galago-tupleflow script on another machine, passing a
   9 # serialized job object as a parameter.
