+If a number is specified, will recurse into repositories at most that many

+Run the specified number of jobs in parallel, or an unlimited number of jobs
+with no number specified. This can greatly speed up operations such as updates.
+It is not recommended for interactive operations.
+
+Note that running more than 10 jobs at a time is likely to run afoul of
+ssh connection limits. Running between 3 and 5 jobs at a time will yeild
+a good speedup in updates without loading the machine too much.
