script to modify cassandra.yaml file

[Anurag Gujral]

Hi All,
          I want to modify the values in the cassandra.yaml which comes with
the cassandra-0.7 package based on values of hostnames,
colo etc.
Does someone knows of some script which I can use which reads in default
cassandra.yaml and write outs new cassandra.yaml
with values based on number of nodes in the cluster ,hostname,colo name etc.

Thanks
Anurag
