Enable excerpts in wordpress page

WordPress in default does not have the excerpt feature on Page.But you can enable this by entering a few lines of code in Theme functions.php of your template.If your theme doesn’t have function.php then please create one.
[highlight]NOTE: Please take a backup of your theme before doing this theme hack.[/highlight]

Here is the code :

// Enable excerpt for wordpress pages
function enable_wp_page_excerpt()
{
    add_post_type_support('page', 'excerpt');
}
add_action('init', 'enable_wp_page_excerpt');
