How can I get the cumulative cpu time of the whole pig script

[Haitao Yao]

hi, all

        With hive, I can get the cumulative cpu time of the whole script. So 
how can I get the similar metrics from pig ? 

        Once optimized the pig script, I can only parse the execution time of 
all the tasks by my own program from the jobtracker, it's boring.

        Can  Pig provide this?

        Thanks.
