Where can I find documentation to custom/silent install 3.5 msi?

I use WPKG to deploy in my company Libreoffice. With early versions I can use the transform template to change the language and remove some components, but with the new msi I can´t find any documentation to do the same.

I would like to use parameter in the msi rather than use Orca to modify the file.



Thanx the wiki has been useful. It was cleaner before, but is still possible to change the languages.
