+*When should I use one of these features?*
 
 Both external sub-DAGs and splices allow you to compose a large workflow from
 various sub-pieces that are defined in individual DAG files.  This is the

-*Feature Comparison*
+Some reasons to use external sub-DAGs or splices:
+*: Create a workflow from separate sub-workflows
+*: Dynamically create parts of the workflow (external sub-DAGs only)
+*: Re-try multiple nodes as a unit (external sub-DAGs only)
+*: Short-circuit parts of the workflow (external sub-DAGs only)
