+  A simple resource type intended to be used as an anchor in a composite class.
+
+      class ntp {
+        class { 'ntp::package': }
+        -> class { 'ntp::config': }
+        -> class { 'ntp::service': }
+
+        # These two resources "anchor" the composed classes
+        # such that the end user may use "require" and "before"
+        # relationships with Class['ntp']
+        anchor { 'ntp::begin': }   -> class  { 'ntp::package': }
+        class  { 'ntp::service': } -> anchor { 'ntp::end': }
+      }
+
+  This resource allows all of the classes in the ntp module to be contained
+  within the ntp class from a dependency management point of view.
+
+  This allows the end user of the ntp module to establish require and before
+  relationships easily:
+
+      class { 'ntp': } -> class { 'mcollective': }
+      class { 'mcollective': } -> class { 'ntp': }
