Multilangguage Site with patTemplate

When you make site for you client, maybe they wont they site's with some language (example : english, indonesia or other) . Here's the idea when you make multilanguage site :
1. You can duplicate the site with language you wont, if the site is in five languages so you must copy/duplicate with five files and this make some space for this copy/duplicate
2. Make one site but support for multilanguage, but this have support and good script for translate the language
3. etc

if you choose number two you can use engine patTemplate
