Subject: is there a way to get the paths to all previously required files?

Let's say I am in irb and I execute

>>require 'base64.rb"
=>true

and then I want to know the path to the base64.rb file,
are the paths to previously required files stored in a global
variable?

I wan't to do something like:
>>$required_files
=>['/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/
ruby/1.8/base64.rb']

Anyone?
Thanks,
Tim

P.S. I know that I can do shift+cmd+D in text mate and open the file,
which obviously requires the path--but this script uses
TM_SUPPORT_PATH--and it seems like something that could be more
easilly accessed directly from RUBY. At any rate, I would rather be
able to do it in irb. Thanks.
