iCalToRSS; is a set of Python scripts I wrote for retrieving iCa events and TODO items and displaying them as RSS newsfeeds inside ;NetNewsWire 2.
I wrote the Python code to parse the iCal calendar files (which are standard RFC2425 Mime-Dir files) and then I use PyRSS2Gen to output the events as RSS news items. Finally NetNewsWire 2.0 executes my scripts and displays the RSS.
