+Rule or group jobs are using `default-resources` unless more threads
+(corresponding to cpus-per-task) or longer run times are required,
+which are specified per rule or group job under `set-threads` or
+`set-resources`, respectively. Memory in MB is automatically calculated
+from the number of threads specified under `default-resources` or
+`set-threads`, respectively.
