*: ReadMultipleUserLogs class vs. MultiLogFiles class
 *: 1-sec sleeps before submits to make sure we can unambiguously order events when reading them back (because the user log timestamps only have a resolution of 1 sec)
 *: why are Condor and Stork events handled with separate ReadMultipleUserLogs objects?  I don't remember -- need to look that up.
+*: default log used if no log specified by submit file -- log file passed on condor_submit_dag command line
+*: in the Dag class: ProcessLogEvents(), ProcessOneEvent(), ProcessAbortEvent(), ProcessTerminatedEvent(), etc.
+*: we don't care about all events
+*: Dag::EventSanityCheck()
+*: cases where events show up in incorrect order (e.g., execute before submit)
