using gulp with modernizr

modernizr.js

// ## Modernizr Task
// config example: https://github.com/Modernizr/Modernizr/blob/master/lib/config-all.json

var gulp = require('gulp');
var modernizr = require('modernizr');
var fs = require('fs');

gulp.task('modernizr', function(callback) {
    'use strict';
    modernizr.build({
        'feature-detects': [
            'touchevents'
        ]
    }, function(file) {
        fs.writeFile('some/path/to/modernizr.js', file, function() {
            return callback();
        });
    });
});

if you don't like the 'gulp-modernizr' module you can just do this..
