ri_cal 0.5.0

This is an UNOFFICIAL version. The public official version will be released on RubyForge. Github will be used for interim versions. USE THIS VERSION AT YOUR OWN RISK. A new Ruby implementation of RFC2445 iCalendar. The existing Ruby iCalendar libraries (e.g. icalendar, vpim) provide for parsing and generating icalendar files, but do not support important things like enumerating occurrences of repeating events. This is a clean-slate implementation of RFC2445. A Google group for discussion of this library has been set up http://groups.google.com/group/rical_gem
