A Ruby port of ec2-delete-old-snapshots
Automatically delete old EBS snapshots from Amazon EC2. Behaves just like the PHP version, except that it expects a ~/.awssecret file to read credentials from, in the format:
aws-access-key-id
aws-secret-access-key
Usage: ec2-delete-old-snapshots.rb [-v VOL_ID] [-o DAYS]
You can specify the -v option multiple times to delete snapshots of multiple volumes in a single invocation.
