+module: synchronize
+version_added: "1.3"
+short_description: Uses rsync to make synchronizing file paths in your playbooks quick and easy.
+description:
+    - This is a wrapper around rsync. Of course you could just use the command action to call rsync yourself, but you also have to add a fair number of boilerplate options and host facts. You still may need to call rsync directly via C(command) or C(shell) depending on your use case. The synchronize action is meant to do common things with C(rsync) easily. It does not provide access to the full power of rsync, but does make most invocations easier to follow.
+options:
+  src:
+    description:
+      - Path on the source machine that will be synchronized to the destination; The path can be absolute or relative.
+    required: true
+  dest:
+    description:
+      - Path on the destination machine that will be synchronized from the source; The path can be absolute or relative.
+    required: true
+  mode:
+    description:
+      - Specify the direction of the synchroniztion. In push mode the localhost or delgate is the  source; In pull mode the remote host in context is the source.
+    required: false
+    choices: [ 'push', 'pull' ]
+    default: 'push'
+  verbosity:
+    description:
+      - An integer controlling the amount of information returned during processing. See the C(-v, --verbose) option of the rsync man page for details. If verbosity is not defined or a value of 0 is assumed, the C(--quiet) option is passed and information is supressed.
+    required: false
+    default: 0
+  delete:
+    description:
+      - Delete files that don't exist (after transfer, not before) in the C(src) path.
+    choices: [ 'yes', 'no' ]
+    default: 'no'
+    required: false
+  rsync_path:
+    description:
+      - Specify the rsync command to run on the remote machine. See C(--rsync-path) on the rsync man page.
+    required: false
