+module: include_files
+short_description: Load variables in a file from a task 
+description:
+     - This module allows loading variables from a yaml file similar to vars_files but from a task.
+        it would be specially useful for conditionally loading vars file from a role. 
+     - These variables will survive between plays.
+options:
+  free-form:
+    description:
+       - Add the file name from which variables should be loaded, if called from a role it will look for 
+         the file in files directory else the path would be relative to playbook. An absolute path can 
+         also be provided.
+    required: false
