-----------------------------------------

+1 for hte changes... the patch would need to be regenerated against the trunk.

> We would like to define certain parts of ZooKeeper's configuration using variables that
get substituted. For example, we want the ZooKeeper quorum to be able to use a dataDir configured
per user. In other words, something like:
> tickTime=2000
> dataDir=/tmp/zookeeper-${user.name}
> clientPort=2181
> initLimit=5
> syncLimit=2
> server.1=zoo1:2888:3888
> server.2=zoo2:2888:3888
> server.3=zoo3:2888:3888
> I think Java already has a system for configuration that allows something like this using
Properties?
