 * It can be embedded like so
 * <iframe name="minical" frameborder="0" height="190" width="250"     src="http://cal/minical.php";> 
 *
 * 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).

 * By default (if you do not edit this file), events for the public
 * calendar will be used
 *
 * Input parameters:
 * You can override settings by changing the URL parameters:
 *   - 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.  
 *    Only NUC Calendar that are marked PUBLIC can be specified
 *
 * Security:
 * $PUBLISH_ENABLED must be set true
 *
