<?php
	add_theme_support('automatic-feed-links');
	if ( ! isset( $content_width ) )
	$content_width = 560;

//Post Thumbnail
if(function_exists('add_theme_support'))
}

//Register Menus
	register_nav_menus( array(
		'primary' => __( 'Primary Navigation', 'scylla' ),
		'footer_menu' => __( 'Footer Navigation', 'scylla' )
	) );
