+/********************************************************************************
+*	Modified from phpicalendar 2.0a distribution by Jim Hu
+*	philosophical changes 
+*		- instead of having separate generators, use a date range for all views (done)
+*		- change the rss generation method to conform to standards(not done)
+*	PHP note: #@ is error control operator to suppress execution halt on error
+*		- used below to deal with undef?
+*
+*	using rssview, RSS feeds can be specified to return events for a given day, week, month, or year 
+*	feeds can be specified for a number of days to or from a given date
+*	feeds can be specified for a range of dates
+*
+*********************************************************************************/

+/* Modified from 2.21 by dyfrin 2006/03/08 19:09:28
+   Changes:
+   -RSS changed to 2.0, encoding removed, languages converted to ISO standard for feeds
+   -RSS title changed to be set by config.inc.php.  Make sure that is added to it. 
+   Lines modified: 135-165, 208-223
