carbon-aggregator.py configs

Hi,

Has anyone messed around with carbon-aggregator.py configurations? There's limited documentation on how to get it up a running. There's no sample configuration file and I don't know what to put the [aggregator] block in carbon.conf. Also what version of graphite supports this? Do you need 0.9.9 or higher? I'm running 0.9.8-1.

Thanks in advance
