/**
 * Processes waiver claims
 *
 * This file should be run via cron.  I recommend once daily on Tues->Sat at 2AM, but you can pick
 * 
 * that line would look like:
 * 
 * 0 2 * * 1-5 /path/to/php /path/to/processwaivers.php
 * 
 * alternately, win32 servers can use pycron (http://www.kalab.com/freeware/pycron/pycron.htm)
 * and have a line like
 * 
 * 0 2 * * 1-5 "c:\path\to\php" "c:\path\to\processwaivers.php"
 * 
 * Since you're not accessing this via the web, you should place it outside of your document root.
 * There are no permission checks; therefore, anyone could prematurely execute a waiver claim if the
 * file is public.  Security through obscurity is a poor substitute.
