 Tested with Cobbler 2.0.11.
 
 Changelog:
+    - 2015-06-21 dmccue: Modified to support run-once _meta retrieval, results in
+         higher performance at ansible startup.  Groups are determined by owner rather than
+         default mgmt_classes.  DNS name determined from hostname. cobbler values are written
+         to a 'cobbler' fact namespace
+
     - 2013-09-01 pgehres: Refactored implementation to make use of caching and to
         limit the number of connections to external cobbler server for performance.
         Added use of cobbler.ini file to configure settings. Tested with Cobbler 2.4.0
