[Mediawiki-l] Template design question

I want to build a Template:MathJax page that will automatically add the following script call to any page/article that has this template included. <script type="text/javascript" src="https://d3eoax9i5htok0.cloudfront.net/mathjax/latest/MathJax.js?c… </script> This script call needs to be placed as a header in an HTML based page according to the sources as its purpose is to render Latex/Tex or MathML inputs into something viewable to the browser. I want to get this same result in Mediawiki 1.17. I am aware that I can install Extension:MathJax but that will require constant maintaining & updating as this is a somewhat active system. It just seems to me that a template is a better way to do this. I am open to suggestions or ideas. I figure this is a tag thing but do not have enough experience to do this quickly. Thanks! frosty
