Simplified example:
@user {
"alice": tag => 'user';
"bob": tag => 'admin';
}
# Realize users tagged as admins, but not other virtual users
User<| tag == 'admin' |>
Selection predicates may use other resource properties, too, not just
tags. See http://docs.puppetlabs.com/puppet/3/reference/lang_virtual.html
for (a bit) more information.
