Using REST service with GeoServer

I have downloaded and installed GeoServer 2.1-RC1 which shipped with RESTconfig. How can i check whether REST service is installed with GeoServer or Not ?

I put this "http://localhost:8080/geoserver/rest" in my browser, but it gives error! ... It means REST service is not installed as i understand. Or is there any other method to check whether the service is installed or not ?

Answer

purpose of this project is to hold a REST client library to interact with GeoServer
