	* e-pilot-map.c: Pilot map functions grabbed from existing conduits

	* e-pilot-map.h (e_pilot_map_write): Header

2000-10-23  JP Rosevear  <jpr@helixcode.com>

	* conduits/todo/Makefile.am: Add libeconduit-static.la

	* conduits/todo/todo-conduit.c (post_sync): Use e_pilot_map_write
	(pre_sync): Use e_pilot_map_read
