aws ec2 tools version

I've been coding a puppet module to install/update the aws EC2 tools on centos.

These are already installed on Amazon Linux servers, and as it happens, on the core AMI used by the business.

The trouble I had was determining the version of the tools that was installed if any. This led to some frustration as the newer features such as
ec2-copy-snapshot --encrypted

are not present in the previous versions of the tools.

well I was very pleased with myself when i found a command to run that told me the version.

ec2-cmd ShowVersion

Certainly not following the standard of --version or similar, but there is it.

The version (as of Feb 2016) is and latest is available here.
