	* cal-client/cal-client-multi.[ch]: new class for managing multiple
	calendars, with an API very similar to the CalClient one,
	for ease of transition from one to the other

	* gui/component-factory.c (xfer_folder, remove_folder, create_folder):
	reworked to be able to manage folders for any calendar backend, and
	not only the file: one

2001-09-18  Rodrigo Moya <rodrigo@ximian.com>

	* idl/evolution-calendar.idl: changed signature for the getFreeBusy
	method, to return a sequence of CalObj's, and added sequence of users
	as a new parameter to that method

	* cal-client/cal-client.c (cal_client_get_free_busy): adapted to new
	IDL method signature, by adding a new "GList *users" parameter, for
	callers to be able to specify a list of users

	* pcs/cal-backend.[ch] (cal_backend_get_free_busy):
	* pcs/cal-backend-file.c (cal_backend_file_get_free_busy): add the
	"GList *users" parameter. In cal_backend_file_get_free_busy, call
	lookup_component to get the CalComponent for each uid, instead
	of calling cal_backend_get_object, which meant converting the
	component to a string and then parsing it again.

	* cal-client/client-test.c (cal_opened_cb):
	* gui/e-itip-control.c (send_freebusy):
	* gui/calendar-commands.c (publish_freebusy_cmd): adapted to
	new getFreeBusy method signature
