This file is the Manolia's file 2.2 + a better readme, contains the steps for install and missing instructions.
I installed on my website and works good. No problems

Important Note: to all those people that want to use the Google XML Sitemap + Ultimate SEO, try setting 'true' to Configuration -> My Store -> Use search-engine safe URLs and re testing the sitemap creation in admin. Good luck

I hope this could help
