Knot Node

A programmatic folly exploring the underbelly of implementing a client-side version of Node.

Exmaple Usage

<script type="text/javascript" src="/knot/process.js"></script>
<script type="text/javascript">
    process(function(exports, require, module) {
        var util = require('util');
        console.log(util.inspect(this, true, 6));
    });
</script>
