We now have a nice generic monthly calendar item for the canvas. We

also have a convenient "Go To" dialog, just like in the PalmPilot.
Next step is a pretty month view - Federico

1998-08-18  Federico Mena Quintero  <federico@nuclecu.unam.mx>

	* gnome-month-item.c (gnome_month_item_day2index): New public
	function to get the displayed day index of the specified date.

	* gnome-cal.c (gnome_calendar_goto_today): New public function to
	jump to the current day.

	* goto.c (day_event): Jump to the selected day when the user
	clicks the mouse, and prelight days as appropriate.

	* timeutil.c (time_from_day): New public function to build a
	time_t from a year/month/day triplet.

	* gnome-month-item.c (gnome_month_item_num2child):
	(gnome_month_item_child2num): New public functions to convert an
	index into a child and vice-versa, respectively.
	(gnome_month_item_num2day): New public function to convert a child
	number into a displayed day number.

	* goto.c (goto_dialog): Doh, use gnome-dialog properly :-)

	* gnome-month-item.c (create_items): Use g_strdup()ed day names
	from the start.

1998-08-17  Federico Mena Quintero  <federico@nuclecu.unam.mx>

	* main.c (gnome_toolbar): Made it use goto.xpm.

	* Makefile.am (EXTRA_DIST): Added goto.xpm to the list of files.
