[Evolution] More importing questions

[David Ronis <ronis montroll chem mcgill ca>]

I'm trying to move from emacs(etc) to evolution-2.4.  I have a calendar
file that is basically free-form, but nonetheless, emacs' calendar mode
has no trouble parsing it.  To get the data into evolution, I've tried:

1) importing the file--no luck--it isn't recognized

2) writing a trivial program to parse the file, write vevent entries
(see below) and then import the file--this does something, but in the
end, I see nothing in the calendar and no error message.

3) manually adding the result of my parse program to
~/.evolution/.evolution/calendar/local/system/calendar.ics (just before
the END:VCALENDAR line).  This doesn't work either (again no error
message).

The basic form of my entries for 2) or 3) is:

                                        BEGIN:VEVENT
                                        DTSTART:20050901T090000
                                        SUMMARY:Classes Start
                                        END:VEVENT
                                        
Lots of fields aren't there, but from the standard's information I've
been able to find on the web, they don't seem to be obligatory.  If this
isn't true, which ones must appear?

4) Finally, (I like this one the best :)):

I deleted ~/.evolution/.evolution/calendar/local/system/calendar.ics and
started evolution.  The calendar entries I'd added via evolution were
still there!  Clearly the information is being stored somewhere else,
and hence, I guess that my manual attempt to hack the file was doomed to
fail.
