Use

As described in the section Settings, besides indicating for each post or page the available translations, the widget can be integrated in a sidebar. It is also possible to directly use the plugin features in your theme. In this blog for instance, I've used the following code in the header.php file of my WordPress theme.

<?php if ( function_exists( 'the_msls' ) ) the_msls(); ?>

There probably will be new other possible features in the next versions of this plugin…
