Here are the areas that should be documented (see gittrac #2815). I re-ordered them somewhat to make the list more logical in terms of related functionality.
*: condor_submit_dag/scheduler universe startup
-*: DAG file parsing
+*: {wiki: DagFileParsing DAG file parsing}
*: {wiki: RescueDag Rescue DAG/condor_rm of DAGMan}
*: {wiki: DagRecovery Recovery mode/condor_hold/condor_release}
*: {wiki: JobOrdering Proper ordering of jobs/scripts (ready queue, etc.)}
