      # This method is intended to provide a convenient way to evaluate a
      # Facter code block only if Puppet is loaded.  This is to account for the
      # situation where the fact happens to be in the load path, but Puppet is
      # not loaded for whatever reason.  Perhaps the user is simply running
      # facter without the --puppet flag and they happen to be working in a lib
      # directory of a module.
