Subject: How do I use :progress_proc from OpenURI::OpenRead?

The below is the code I'd like a progress bar for once it is ran on the
command line:

 open(File.join(CWD, name), 'wb') do |f|
   f << open(url).read
 end

I found OpenURI::OpenRead :progress_proc and it seems like it's exactly
what I want. I'm not too sure how to implement it though. Also, does it
use ruby-progressbar? Is this what they mean by Ruby/ProgressBar:

> For example, it can be implemented as follows using Ruby/ProgressBar.

So, all I want from it is some kind of text-based progress bar while the
file is being downloaded. Is :progress_proc the thing I need to use to
do that?

Thanks.
