Well, you'd have to make a trivial DAG file.  For example, if you have a 
submit file A.sub, you'd have to make a DAG file like this:

  JOB foo A.sub

and then run condor_submit_dag on that.

But, if you have a DAG with a single job, you don't really gain anything 
by submitting it via DAGMan.  It makes sense to submit a *collection* of 
independent jobs via DAGMan to use the throttling features, though.  (One 
note about that -- the throttling features are *per DAGMan*, not global, 
so if you do several condor_submit_dags with, say, maxjobs set, each one 
throttles independently.)

Another idea along these lines -- I had thought of adding a feature to 
allow condor_submit_dag to work directly with the submit files (without a 
DAG file) for the case where you just want to use DAGMan to throttle 
independent jobs.  Maybe something like this:

  condor_submit_dag -sub A.sub B.sub C.sub ...

Would people find this useful?  (All it would mean is that you wouldn't 
have to bother to make the degenerate DAG file.)
