+  clear_meta:
+    description:
+      - Optionally clear existing metadata when applying metadata to existing containers.
+      - Selecting this option is only appropriate when setting type=meta

+  meta:
+    description:
+      - A hash of items to set as metadata values on a container
+  private:
+    description:
+      - Used to set a container as private, removing it from the CDN.
+      - Warning: Private containers, if previously made public, can have live objects available until the TTL on cached objects expires
+  public:
+    description:
+      - Used to set a container as public, available via the Cloud Files CDN
+  region:
+    description:
+      - Region to create an instance in

+      - Rackspace username (overrides I(credentials))
+  web_error:
+    description:
+       - Sets an object to be presented as the HTTP error page when accessed by the CDN URL
+  web_index:
+    description:
+       - Sets an object to be presented as the HTTP index page when accessed by the CDN URL
+requirements: [ "pyrax" ]
+author: Paul Durivage
+notes:
+  - The following environment variables can be used, C(RAX_USERNAME),
+    C(RAX_API_KEY), C(RAX_CREDS_FILE), C(RAX_CREDENTIALS), C(RAX_REGION).
+  - C(RAX_CREDENTIALS) and C(RAX_CREDS_FILE) points to a credentials file
+    appropriate for pyrax. See U(https://github.com/rackspace/pyrax/blob/master/docs/getting_started.md#authenticating)
+  - C(RAX_USERNAME) and C(RAX_API_KEY) obviate the use of a credentials file
+  - C(RAX_REGION) defines a Rackspace Public Cloud region (DFW, ORD, LON, ...)
