1998-08-10  Federico Mena Quintero  <federico@nuclecu.unam.mx>

	* month-view.[ch]: Start of the month view widget.  This will use
	the generic month item and extend it to have the semantics desired
	for the gnomecal month view.

	* gnome-month-item.[ch]: New generic canvas item for the month
	view and the "small calendars".  This is intended to be a
	high-level display engine for monthly calendars.  This is a work
	in progress.

	* gnome-cal.h (GnomeCalendar): Added a month_view field.

	* gnome-cal.c (setup_widgets): Create the month view and insert it
	into the notebook.

	* Makefile.am: Added month-view.[ch] and gnome-month-item.[ch] to
	the sources.
