-Recovery mode is a mode in which DAGMan "catches up" with what has happened with the node jobs of its DAG before actually submitting any new jobs.  Basically, we get into recovery mode if a DAG was running and DAGMan exited in a way that didn't create a rescue DAG, and then DAGMan was restarted.  There are two main ways that this can happen:
+Recovery mode is a mode in which DAGMan "catches up" with what has happened with the node jobs of its DAG before actually submitting any new jobs (it does the "catching up" by reading the user log files of the node jobs).  Basically, we get into recovery mode if a DAG was running and DAGMan exited in a way that didn't create a rescue DAG, and then DAGMan was restarted.  There are two main ways that this can happen:
 
 *: condor_hold/condor_release of the condor_dagman job.
 *: DAGMan exits without creating a rescue DAG because of something like an assertion.
