+"""
+Script that checks if an outcomes file exists for an RT parsing job.  If it exists, that means the job completed successfully.
+
+If it doesn't exist, the job either failed midway or or never ran.  This only properly analyzes results from the parse_and_validate_v2 airflow job.  In the new airflow job parse_and_validate,
+now each agency is parsed separately so it's possible some agencies were parsed and others were not.
