* $Id: get_events.php,v 1.1 2004/06/24 02:18:30 cknudsen Exp $
*
* Description:
* Web Service functionality to get events.
* Uses XML (but not SOAP at this point since that would be
* overkill and require extra packages to install).
*
* Comments:
* Client apps must use the same authentication as the web browser.
* If WebCalendar is setup to use web-based authentication, then
* the login.php found in this directory should be used to obtain
* a session cookie.
*
