This module can be used to generate diff markup for two strings.

    var vows = require('vows')
      , diff = require('../diff')
      , assert = require('assert');
      
    vows.describe('Diff Tests').addBatch({
        'see that it works': {
            topicfunction() {
                return diff(
                    'The red brown fox jumped over the rolling log.',
                    'The brown spotted fox leaped over the rolling log'
                );
            },
            'as expected'function(topic) {
                assert.equal(topic, ' The <del>red </del> brown <ins>spotted </ins> fox <del>jumped </del><ins>leaped </ins> over  the  rolling <del>log.\n</del><ins>log\n</ins>');
