-  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
