A question about the hadoop examples

Hi,everyone!
     I just have a question about the example which compute the pi using monte-karo method. Why when i run it i must use "pi" for the class name rather than use "PiEstimator" ???  Thanks very much .


                                               Sincerely yours,
                                                 Superxgl

ExampleDriver switches on the argument - it's not an explicit class name.
The jar itself lists ExampleDriver as its main class in its manifest - look
at build.xml.
