+Puppet::Type.newtype(:anchor) do
+  desc <<-'ENDOFDESC'
+  A simple resource type intended to be used as an anchor in a composite class.
+
+  In Puppet 2.6, when a class declares another class, the resources in the
+  interior class are not contained by the exterior class. This interacts badly
+  with the pattern of composing complex modules from smaller classes, as it
+  makes it impossible for end users to specify order relationships between the
+  exterior class and other modules.
+
+  The anchor type lets you work around this. By sandwiching any interior
+  classes between two no-op resources that _are_ contained by the exterior
+  class, you can ensure that all resources in the module are contained.
+
+      class ntp {
+        # These classes will have the correct order relationship with each
+        # other. However, without anchors, they won't have any order
+        # relationship to Class['ntp'].
+        class { 'ntp::package': }
+        -> class { 'ntp::config': }
+        -> class { 'ntp::service': }
+
+        # These two resources "anchor" the composed classes within the ntp
+        # class.
+        anchor { 'ntp::begin': } -> Class['ntp::package']
+        Class['ntp::service']    -> anchor { 'ntp::end': }
+      }
+
+  This allows the end user of the ntp module to establish require and before
+  relationships with Class['ntp']:
+
+      class { 'ntp': } -> class { 'mcollective': }
+      class { 'mcollective': } -> class { 'ntp': }

+Puppet::Type.newtype(:file_line) do
+
+  desc <<-EOT
+    Ensures that a given line is contained within a file.  The implementation
+    matches the full line, including whitespace at the beginning and end.  If
+    the line is not contained in the given file, Puppet will add the line to
+    ensure the desired state.  Multiple resources may be declared to manage
+    multiple lines in the same file.
+
+    Example:
+
+        file_line { 'sudo_rule':
+          path => '/etc/sudoers',
+          line => '%sudo ALL=(ALL) ALL',

+          path => '/etc/sudoers',
+          line => '%sudonopw ALL=(ALL) NOPASSWD: ALL',
+        }
+
+    In this example, Puppet will ensure both of the specified lines are
+    contained in the file /etc/sudoers.
+
+    **Autorequires:** If Puppet is managing the file that will contain the line
+    being managed, the file_line resource will autorequire that file.
