I have a PHP website that contains a lot of technical content. I created a glossary for some of the more obscure terms used on the website. I would like tooltips (or hint bubbles, whatever they're called) to be displayed whenever a user hovers over one of these terms. 

I found a ton of jQuery extensions that seem to do what I want but they need to be manually linked to each term instance by setting a `span` tag to a specific class.

I want this done automatically. How should I proceed?
