    Maybe 99.9% of Digg users won't need this information right this minute, but it's still a very useful tutorial. And now that it's on Digg, folks can tag it and they won't need to sort through 10 million Google search pages to find it later. That alone is worth a digg, don't you think?

    But if you want to, it can be very, very powerful. The -R (recursive) option is one example.
