This is a node.js module for controlling iptables. It's very basic just for
what we need at http://browserling.com.

It was written by Peteris Krumins (peter@catonmat.net, @pkrumins on twitter).

Here is an example usage:

    var iptables = require('iptables');

    iptables.allow({
        protocol : tcp,
        src : '10.1.1.5',
        dport : 34567,
        sudo : true
    });

    iptables.drop({
        protocol : 'tcp',
        dport : 34567,
        sudo : true
    });

This allows connections to port 34567 from 10.1.1.5 and drops connections from
the same port from everyone else.
