Do you want to offer WPML together with your multilingual-ready themes? Now you can, using WPML's Embedded Installer.
The Embedded Installer is a tiny piece of PHP, created for theme authors. When you include it in your themes, it offers your clients to buy, install and activate WPML from inside the theme.
No need to use an FTP program to upload and unzip. Your clients also enjoy automated upgrades for WPML, without any hassle.
Since you are responsible for sales coming from inside your theme, you receive a nice affiliate commission for every sale that comes from the Embedded Installer.
