Subject: Capturing output from Kernel#system

Maybe I'm dumb, I dunno.

I need to execute an external command and capture the output from it in a
Ruby structure.

When I use the Kernel#system method to do this, I get the output just
fine, but I can't figure out how to capture it. The method returns true,
of course, but obviously true isn't what I want to capture!

I'd like to avoid the obvious kludge of writing the command output to a
file and reading the file in Ruby. Isn't there a better way than that? The
pickaxe book isn't helping me here at all (maybe I didn't look where I
should have...).

Thanks for any help you can provide.
