/********************************************************************************
* 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

-RSS changed to 2.0, encoding removed, languages converted to ISO standard for feeds
