For example, when I browse to the jQuery TOOLS download section, I see this:

Quick start

Insert the following line on your HTML page and you are done!

<script src="/js/tools/1.1.2/jquery.tools.min.js"></script>

When I am quite sure it should show something like this:

<script src="http://cdn.jquerytools.org/1.1.2/jquery.tools.min.js"></script>

Similarly, when I check out the standalone version of "Using tooltips in form fields", none of the jquery loads. I see this in the source:

<script src="/js/tools/1.1.2/jquery.tools.min.js"></script>

When I try to view the script that is being referenced, I see this:

Invalid version requested: tools
