I'd really like to find an open source command line editor for iCalendar (ics) files. I generally maintain my calendars using iCal on OS X, but the iCal client does not allow write access to calendars you've subscribed to even if the server settings allow it. So sometimes I want to edit a calendar directly on the server and all I have is ssh terminal access.
I've gone on google hunts (and sourceforge, rubyforge and freshmeat hunts) for this several times but somehow can never come up with one even though I know one must exist. I could probably write one in under an hour using a ruby or perl library, but there has to be a more robust full-featured one than I could do in an hour out there.
Anyone know of one?
