Custom index page <title> tag

[polyfragmented]

Something I implemented today for my H1 page heading by way of I18N Custom Fields. This outputs the custom field if it is populated:

Code:

<?php            
        if (return_custom_field('ueberschrift')) {                    
            get_custom_field('ueberschrift');                    
        } else {                    
            get_page_title();                        
        }                
    ?>
