+    Copies your project to the remote servers. This is the first stage \
+    of any deployment; moving your updated code and assets to the deployment \

+    should call the `deploy' task (to do a complete deploy) or the `update' \
+    task (if you want to perform the `restart' task separately).
+    You will need to make sure you set the :scm variable to the source \
+    control software you are using (it defaults to :subversion), and the \
+    :deploy_via variable to the strategy you want to use to deploy (it \
+    defaults to :checkout).
