	* conduits/todo/Makefile.am: Fix build slightly

	* pcs/cal.c (build_change_seq): Build a corba sequence out of a
list
	of CalObjChanges
	(Cal_get_objects_in_range): Implement new corba function

	* pcs/cal-backend.c (cal_backend_init): Intiliaze to NULL
	(cal_backend_load): Track the uri so we can write the log file
	to the same place
	(cal_backend_log_name): Figure out the log filename/path based on

written
	out

	(cal_backend_log_sax_start_element): SAX callback for reading in
	log entries
	(cal_backend_log_sax_end_element): ditto
	(cal_backend_log_sax_parse): Main SAX parser call to parse the log
	file looking for particular log entries and creating a
CalObjChange
	hash with the last change for each object

given
	type changed since the given time
	(cal_backend_update_object): Add appropriate log entries
	(cal_backend_remove_object): ditto

list

	* pcs/cal-backend-imc.[hc]: Remove crufty files

	* pcs/cal-backend-file.c (cal_backend_file_get_type_by_uid): New
	function that returns the CalObjType for a uid.

	* cal-client/cal-client.h: Update prototypes.

	* cal-client/cal-client.c (build_change_list): Build a list
	of CalObjChange items from a corba sequence.
	(cal_client_get_changed_uids): New accessor method for the
	similarly named addition to the idl file.

	* cal-util/cal-util.h: Update prototypes and add CalObjChangeType
	enum.
