<?php 
	// This whole thing goes into a page template,
	// so we can get the page object via the_post() here
	global $wp_query;
	the_post(); 
				
	// Store page slug for later
	$gp_current_page_slug = $post->post_name;

	// Page content

	// Do whatever else here...

	// Reset post data for later query
	wp_reset_postdata(); ?>

	// Assume we have registered a widget area and based its name on the page slug
