+#   http://docs.pythonboto.org/en/latest/ref/ec2.html#module-boto.ec2.instance
+# Below are 2 variables that are used as the address of a server:
+#   - destination_variable
+#   - vpc_destination_variable
+
+# This is the normal destination variable to use. If you are running Ansible
+# from outside EC2, then 'public_dns_name' makes the most sense. If you are
+# running Ansible from within EC2, then perhaps you want to use the internal
+# address, and should set this to 'private_dns_name'.
+destination_variable = public_dns_name
+
+# For server inside a VPC, using DNS names may not make sense. When an instance
+# has 'subnet_id' set, this variable is used. If the subnet is public, setting
+# this to 'ip_address' will return the public IP address. For instances in a
+# private subnet, this should be set to 'private_ip_address', and Ansible must
+# be run from with EC2.
+vpc_destination_variable = ip_address

+# call. Set this to the path you want cache files to be written to. Two files
+# will be written to this directory:
+#   - ansible-ec2.cache
+#   - ansible-ec2.index
+cache_path = ~/.ansible/tmp
+
+# The number of seconds a cache file is considered valid. After this many

+'''
+EC2 external inventory script
+=================================
+
+Generates inventory that Ansible can understand by making API request to
+AWS EC2 using the Boto library.
+
+NOTE: This script assumes Ansible is being executed where the environment
+variables needed for Boto have already been set:
+    export AWS_ACCESS_KEY_ID='AK123'
+    export AWS_SECRET_ACCESS_KEY='abc123'
+
+This script also assumes there is an ec2.ini file alongside it.  To specify a
+different path to ec2.ini, define the EC2_INI_PATH environment variable:
+
+    export EC2_INI_PATH=/path/to/my_ec2.ini
+
+If you're using eucalyptus you need to set the above variables and
+you need to define:
+
+    export EC2_URL=http://hostname_of_your_cc:port/services/Eucalyptus
+
+For more details, see: http://docs.pythonboto.org/en/latest/boto_config_tut.html
+
+When run against a specific host, this script returns the following variables:
+ - ec2_ami_launch_index
+ - ec2_architecture
+ - ec2_association
+ - ec2_attachTime
+ - ec2_attachment
+ - ec2_attachmentId
+ - ec2_client_token
+ - ec2_deleteOnTermination
+ - ec2_description
+ - ec2_deviceIndex
+ - ec2_dns_name
+ - ec2_eventsSet
+ - ec2_group_name
+ - ec2_hypervisor
+ - ec2_id
+ - ec2_image_id
+ - ec2_instanceState
+ - ec2_instance_type
+ - ec2_ipOwnerId
+ - ec2_ip_address
+ - ec2_item
+ - ec2_kernel
+ - ec2_key_name
+ - ec2_launch_time
+ - ec2_monitored
+ - ec2_monitoring
+ - ec2_networkInterfaceId
+ - ec2_ownerId
+ - ec2_persistent
+ - ec2_placement
+ - ec2_platform
+ - ec2_previous_state
+ - ec2_private_dns_name
+ - ec2_private_ip_address
+ - ec2_publicIp
+ - ec2_public_dns_name
+ - ec2_ramdisk
+ - ec2_reason
+ - ec2_region
+ - ec2_requester_id
+ - ec2_root_device_name
+ - ec2_root_device_type
+ - ec2_security_group_ids
+ - ec2_security_group_names
+ - ec2_shutdown_state
+ - ec2_sourceDestCheck
+ - ec2_spot_instance_request_id
+ - ec2_state
+ - ec2_state_code
+ - ec2_state_reason
+ - ec2_status
+ - ec2_subnet_id
+ - ec2_tenancy
+ - ec2_virtualization_type
+ - ec2_vpc_id
+
+These variables are pulled out of a boto.ec2.instance object. There is a lack of
+consistency with variable spellings (camelCase and underscores) since this
+just loops through all variables the object exposes. It is preferred to use the
+ones with underscores when multiple exist.
+
+In addition, if an instance has AWS Tags associated with it, each tag is a new
+variable named:
+ - ec2_tag_[Key] = [Value]
+
+Security groups are comma-separated in 'ec2_security_group_ids' and
+'ec2_security_group_names'.
