/********************************************************************************
-* 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
-*
+changed to use rss_common
