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': {
            topic: function() {
                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.</del><ins>log</ins>');
            }
        }
