// Create a sitemap for better indexing by search engines.
// <http://www.sitemaps.org/>
// You can either use this to dynamically generate sitemaps or can make a
// crontab entry to wget it (saving execution time & allowing you to manually
// gzip the file (if your webserver doesn't already do this for you).
// TODO:
// - Handle cases where there are >50,000 URLs
// - Possibly come up with smart ways to specify changefreq and priority
// Incorporate some include files:
include 'initialize/db.inc.php'; // 'db.inc.php' is included to hide username and password
include 'includes/include.inc.php'; // include common functions
include 'initialize/ini.inc.php'; // include common variables
