Simple Drupal 6 Module

Need help including external javascript files into specific drupal pages. For example, if I have a javascript file called [login to view URL] I would like the ability to include this only on specific pages, but without creating multiple [login to view URL] files I also don't want to simply include all fo my javascript files in [login to view URL] to load for every page (As that's extremely inefficient). I'd just like it to be as simple as it it with a static html site, i.e. simply linking to the external file in the header. A potential idea is to have an "include" field in the create a page/story etc area so I can simply write the html that should be stuck in the header on page load. ## Deliverables Although I've made a suggestion for what I'd like to see (As it seems the easiest to use to me) I'm open to suggestions, as long as it fulfils the requirements. I feel that $50 would be appropriate for this project, as I imagine it's a common request and from what I've seen and heard, it isn't a great deal of work. The implementation must allow me to load multiple javascript files in the header. It must also work with drupal version 6 and not break when drupal 7 is released as a stable version. It must also not modify core drupal files and should simply work with any theme. Any questions, feel free to ask.
