+Queue Access Control Lists (ACLs)

+  Queue Access Control Lists (ACLs) allow administrators to control who may
+  take actions on particular queues. They are configured with the aclSubmitApps
+  and aclAdministerApps properties, which can be set per queue. Currently the
+  only supported administrative action is killing an application. Anybody who
+  may administer a queue may also submit applications to it. These properties
+  take values in a format like "user1,user2 group1,group2" or " group1,group2".
+  An action on a queue will be permitted if its user or group is in the ACL of
+  that queue or in the ACL of any of that queue's ancestors. So if queue2
+  is inside queue1, and user1 is in queue1's ACL, and user2 is in queue2's
+  ACL, then both users may submit to queue2.
+  
+  The root queue's ACLs are "*" by default which, because ACLs are passed down,
+  means that everybody may submit to and kill applications from every queue.
+  To start restricting access, change the root queue's ACLs to something other
+  than "*".
