Gets the job done.
Shiv is a work-in-progress JavaScript toolkit for bare-bones JS testing. Currently it's just the minimum I need for two similar projects (that are not in production).
It's written completely from scratch and is still extremely raw.
<script type="text/javascript" src="../shiv.js"></script>
<script type="text/javascript">
shiv.addOnLoad(function() {
shiv.prefix = "../js/";
shiv.load("shiv-util");
});
</script>
