/*
* $Id: upcoming.php,v 1.18.2.1 2005/05/26 13:44:04 cknudsen Exp $
*
* Description:
* This script is intended to be used outside of normal WebCalendar
* use, typically as an iframe in another page.
*
* You must have public access enabled in System Settings to use this
* page (unless you modify the $public_must_be_enabled setting below
* in this file).
*
* Typically, this is how you would reference this page from another:
*
* <iframe height="250" width="300"
* scrolling="yes" src="upcoming.php"></iframe>
*
* By default (if you do not edit this file), events for the public
* calendar will be loaded for either:
* - the next 30 days
* - the next 10 events
*
* Input parameters:
* You can override settings by changing the URL parameters:
* - days: number of days ahead to look for events
* - cat_id: specify a category id to filter on
* - user: login name of calendar to display (instead of public
* user), if allowed by System Settings. You must have the
* following System Settings configured for this:
* Allow viewing other user's calendars: Yes
* Public access can view others: Yes
*
* Security:
* TBD
