good catch. though given how simple the script is I think it's better to
just make the script compatible for version 2 and 3.

The only issue here is print which can be replaced with str.format(). That
is only available in 2.6 and above, but given that even RHEL6 ships 2.6,
that's a reasonable requirement.

Cheers,
