Description

Registers support of certain feature(s) for a given post type. Each feature has a direct impact on the corresponding field displayed in the post edit screen, such as the editor or a meta box. Additionally, the 'revisions' feature dictates whether the post type will store revisions, and the 'comments' feature dictates whether the comments count will show on the post edit screen.

 */
function wpcodex_add_excerpt_support_for_pages() {
	add_post_type_support( 'page', 'excerpt' );
}
