flume configuration in zookeeper

[Simeon Zaharici]

Hi guys,
Do you have an example of how to use the dynamic configuration with zookeeper  
https://issues.apache.org/jira/browse/FLUME-1491?
I started flume with the -z flag pointing to a zookeeper instance and I see 
that it created a flume 
znode but I am not sure how to actually put the configuration in zookeeper.  
Thanks,Simeon
