+ovirt external inventory script
+=================================
+
+Generates inventory that Ansible can understand by making API requests to
+oVirt via the ovirt-engine-sdk-python library.  Full install/configuration
+instructions for the ovirt* modules can be found in the comments of
+ansible/test/ovirt_tests.py.
+
+When run against a specific host, this script returns the following variables
+based on the data obtained from the ovirt_sdk Node object:
+ - ovirt_uuid
+ - ovirt_id
+ - ovirt_image
+ - ovirt_machine_type
+ - ovirt_ips
+ - ovirt_name
+ - ovirt_description
+ - ovirt_status
+ - ovirt_zone
+ - ovirt_tags
+ - ovirt_stats
+
+When run in --list mode, instances are grouped by the following categories:
+
+ - zone:
+   zone group name.
+ - instance tags:
+   An entry is created for each tag.  For example, if you have two instances
+   with a common tag called 'foo', they will both be grouped together under
+   the 'tag_foo' name.
+ - network name:
+   the name of the network is appended to 'network_' (e.g. the 'default'
+   network will result in a group named 'network_default')
+ - running status:
+   group name prefixed with 'status_' (e.g. status_up, status_down,..)
+
+Examples:
+  Execute uname on all instances in the us-central1-a zone
+  $ ansible -i ovirt.py us-central1-a -m shell -a "/bin/uname -a"
+
+  Use the ovirt inventory script to print out instance specific information
+  $ plugins/inventory/ovirt.py --host my_instance
