Example code: Testing relationships to base classes

I think I promised a while ago to start posting the example code I use for tests.

Here's the code I used to reproduce #1030:

class base {
    notify { "This is the base class": }
}

class sub inherits base {
    notify { "This is the sub class": }
}

include sub

notify { "This is the main class": require => Class[base] }

Sure enough, I get this exception:

luke@phage(0) $ test.pp
Could not find dependency Class[base] for Notify[This is the main class] at /Users/luke/bin/test.pp:41
luke@phage(1) $

Turns out the problem is in lib/puppet/parser/compile.rb; or rather, the problem is that the code is in this file, instead of in lib/puppet/parser/ast/hostclass.rb. The Compile class creates a resource for every class it evaluates, which is how these relationships work, but it's that AST class that actually knows when base classes are evaluated by a subclass, so it needs to be creating these resources.

Jeff McCune posts his WWDC examples

Jeff McCune has posted his example code from WWDC. He gave a short (and apparently very well received) presentation on Puppet there, and he's now not only posted the example code but he promises more in the near future.
