Hi All
Thanks for the pointers. reading them I see that what I intend to can
certainly be done without much pain. However with my test scripts I am not
able to fully understand Rscript. The ?Rscript option doesnt print out a lot
to help me get the minute details.

Any good example/s or some info on Rscript will help.

Thanks,
-Abhi
