Subject: Is there an online reference for dollar ($) variables?

Is there an online reference that describes all the Ruby $... variables?
Are there any search engines that allow you to search for something like
$: ? Is there anything in the Rdocs?

Personally, I'm very happy with the list of $... variables found in the
2nd edition of Ruby Programming. However a few of my colleagues do not
have a copy of this book.  While I try to avoid using them there are
times when it's almost unavoidable. For example, I haven't found any way
to append new directories to the Load Path $: within my Ruby code
(specifically my Rakefile).

Thanks,
Larry
