New file. Implements PalmPilot syncronization with the Gnome Calendar.

1999-07-28  Miguel de Icaza  <miguel@gnu.org>

	* calendar-pilot-sync.c: New file.  Implements PalmPilot
	syncronization with the Gnome Calendar.

1999-07-27  Miguel de Icaza  <miguel@gnu.org>

	* calobj.c (ical_object_new_from_string): New function.  Creates
	an iCalObject from a vCalendar string that is supposed to contain
	only one vEvent.

	* calendar.c:
	(calendar_save): Split this routine in two.

	* gnome-cal.c (gnome_calendar_new): Create the corba server here.

	* main.c: Include gnorba.h, and corba-cal-factory.h here
	(close_cmd): Kill the calendar server on shutdown.

	* calobj.c (load_recur_yearly_day): Added a fixme comment.  WE
	need to handle intervals in the years.

	* calendar.c (calendar_object_find_in_list, calendar_object_find,
	calendar_object_find_todo, calendar_object_find_event): New
	functions for looking up information.

	* main.c (gnome_calendar_locate): New function.

	* corba-cal.c (calendar_create_object): New file.  Implements the
	corba server.

	* calendar.c (calendar_object_changed): Flag pilot-status as changed.

	* calobj.c (ical_object_to_vobject): Save pilot information for syncing.
	(ical_object_create_from_vobject): Load syncing information for
	pilot.  Do it in a way compatible with KOrganizer.

1999-07-26  Miguel de Icaza  <miguel@gnu.org>

	* calobj.c (ical_object_create_from_vobject): Generate unique IDs
	on Vevents we load that lack it.  WE need this for the old
	gnome calendar generated files (ie, before now :-).
