Hi Alex,
We have a page on our website that should help you out with this -->
http://docs.puppetlabs.com/guides/scope_and_puppet.html Have you seen that
yet? That's a great place to start. You have parameterized classes that
can help you out, as well as data lookup methods like Hiera (
http://github.com/puppetlabs/hiera) that are also available.
