Puppet::Parser::Functions::newfunction(:add_arguments, :doc => <<-'ENDHEREDOC') do |args|
    Converts a hash into a set of arguments that are added to the specified resource.

    This function takes two arguments: a resource name, and a hash describing
    a set of resources. The hash should be in the form `{title => {parameters} }`:

        # A hash of arguments:
        $myarguments = {
           uid    => '1330',
           group  => allstaff,
           groups => ['developers', 'operations', 'release'],
        }

        add_arguments(User["al"], $myarguments)

  ENDHEREDOC
  raise ArgumentError, ("add_arguments(): wrong number of arguments (#{args.length}; must be 2)") if args.length != 2
  resource_name = args[0]

  args[1].each do |title, params|
    raise ArgumentError, 'params should not contain title' if(params['title'])

      p_resource = Puppet::Parser::Resource.new(resource_name)
      # p_resource = Puppet::Parser::Resource.new(type_name, title, :scope => self, :source => resource)
      params.merge(:name => title).each do |k,v|
        p_resource.set_parameter(k,v)
      end
  end
end
