Subject: Capturing the output of an external program line by line

Hi,

I want to run an external program in ruby. The external program takes 
a long time to execute. While running, it gives the information on 
stdout about what it is doing. How can I run the external program 
inside ruby so that I can capture this information, and display it on 
stdout? I tried %x{...}, `...` and system("...."), but all of them 
give me a result AFTER the external program has finished executing, 
not during its execution.

Thanks,
Aditya
