+module: rax_network
+short_description: create / delete an isolated network in Rackspace Public Cloud
+description:
+     - creates / deletes a Rackspace Public Cloud isolated network.
+version_added: "1.4"
+options:
+  state:
+    description:
+     - Indicate desired state of the resource
+    choices: ['present', 'absent']
+    default: present
+  credentials:
+    description:
+     - File to find the Rackspace credentials in (ignored if C(api_key) and
+       C(username) are provided)
+    default: null
+    aliases: ['creds_file']
+  api_key:
+    description:
+     - Rackspace API key (overrides C(credentials))
+  username:
+    description:
+     - Rackspace username (overrides C(credentials))
+  label:
+    description:
+     - Label (name) to give the network
+    default: null
+  cidr:
+    description:
+     - cidr of the network being created
+    default: null
+  region:
+    description:
+     - Region to create the network in
+    default: DFW
+requirements: [ "pyrax" ]
+author: Christopher H. Laco, Jesse Keating
+notes:
+  - The following environment variables can be used, C(RAX_USERNAME),
+    C(RAX_API_KEY), C(RAX_CREDS), C(RAX_CREDENTIALS), C(RAX_REGION).
+  - C(RAX_CREDENTIALS) and C(RAX_CREDS) points to a credentials file
+    appropriate for pyrax
+  - 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, ...)
