 Run the Revel web application named by the given import path.
 
 For example, to run the chat room sample application:
 
-    revel run github.com/revel/examples/chat dev

 The run mode is used to select which set of app.conf configuration should
 apply and may be used to determine logic in the application itself.
 
 Run mode defaults to "dev".
