Below is an HTCondor submit file generated by condor_submit_dag.  Note 
that if you spawn condor_dagman as a process, you'll have to pass most of 
the arguments below or condor_dagman won't run.

Also, you *must* have _CONDOR_DAGMAN_LOG set in the environment or 
condor_dagman won't run.  I'm not sure if you absolutely need the other 
environment variables.
