	sanei_scsi_find_devices() support to OS/2.

	* sanei/sanei_pio.c: Include <sane/sanei_backend.h> instead of

	Added code to cause sane_read to read as much data from scanner as
	possible for each call, previously would read 1 line max from

	Added code to attempt to detect scanner capabilities from scanner
	if scanner supports this command, it not program has defaults
	coded in for certain scanner models.

	the gamma-table twice.

	* frontend/scan.c (main): Reinstantiate BROKEN_GETOPT code.

	versions of glibc had a buggy getopt().
	* lib/getopt1.c: Ditto.

	* frontend/Makefile.in (xscan): Mention $(LIBSANEI).

	(LIBSANEI_LTOBJS):  Remove sane_strstatus.lo.

	* backend/Makefile.in (libsane-%.la): Mention sane_strstatus.lo

	* backend/mustek.c (reader_process): Rename macro

	* backend/pnm.c (sane_read, sane_start, getparmfromfile): Handle
 	grayscale and monochrome bitmapped PNM files.

	new getopt() works properly when making multiple passes over the
	argument list.

Fri Mar 28 21:33:36 1997  Gordon Matzigkeit  <gord@gnu.ai.mit.edu>

	* configure.in: Make the QuickCam device conditional on whether or

	* backend/net.c (connect_dev): Ensure dev->ctl gets closed and

	ignore old GTK versions against which we can't build.

	* (config.sub): Replace with version that comes with
 	autoconf-2.12.  The version that came with libtool-0.9
	doesn't like i686-unknown-linux.

	this function.

	* frontend/gtkglue.c (unit_string): New function.
	(panel_build): Append unit_string () to option's title if
	the unit is not SANE_UNIT_NONE.  Use "title" instead of opt->title
	when creating widgets.

	* frontend/preview.c (preview_update): Compute width/height as
	(max - min + eps) where eps is 1 for integer coordinates and
 	SANE_UNFIX(1) for fixed-point coordinates.
	(display_partial_image): Support different scaling in x/y
 	direction.  In the case where surface_unit == SANE_UNIT_PIXEL,
 	compute xscale/yscale based on the ratio between the _expected_
 	width/height and the actual width/height.  If they're not equal,
 	the backend must be doing some scaling (e.g., transfer-scale in
 	the qcam backend).

	* frontend/xscan.c (init): Disable gtk_rc_parse () calls for now
	since gtk styles seem to be a bit buggy right now.
	(scan_done): Remove input_tag if it is >= 0.

 	default-button---it's too easy to cancel by mistake otherwise.

	* frontend/sane-style.rc: New file.

	* frontend/xscan.c (init): New function.  Parse gtk_rc_parse ()
	on /usr/local/share/sane-style.rc and ~/.sane/sane-style.rc if
	those files exist.

	* configure.in (CPPFLAGS): Add PATH_SANE_DATA_DIR.

	* frontend/gtkglue.c (gsg_warning): New function.
	(gsg_message): New function.

	preference.

	* frontend/xcam.c (delayed_switch): New function.

 	until GTK+ has been fixed.
	(idle_handler): New function: rebuild dialog if dialog->rebuild is
 	set.

 	idle_handler() rather than directly calling panel_rebuild().  Pete
 	tells me GTK is not designed to have a widget rebuilt while a
 	submenu is active.
	(gsg_refresh_dialog): Ditto.

Thu Mar 27 14:54:23 1997  Gordon Matzigkeit  <gord@gnu.ai.mit.edu>

	empty to use a temporary list variable.

	* frontend/Makefile.in (scan): Added getopt.o, getopt1.o to scan
	dependencies.

	* frontend/getopt.c, frontend/getopt1.c, include/getopt.h: Added
	to the distribution.

	direction change ends up at the end of the output file.
	Added option parsing, a usage message, and other cleanups.

	@ALLOCA@ and @LTALLOCA@ as appropriate.

	* configure.in (AM_FUNC_ALLOCA): Use it.

 	is on (instead of pixel unit).
	(mode_select): Set bit 3 in mode byte only if
 	MUSTEK_FLAG_USE_EIGHTS is off.
	(encode_resolution): Don't do funky encoding for 3-pass scanners
 	in 10% resolution mode.  It seems the docs are wrong and the
 	actual scanners require a much simpler setup.

	* backend/metadl.c (sane_init): Call DBG_INIT() and declare
	debug level variable with DBG_DECL.  Added various debug
	statements.

	* backend/pnm.c (sane_init): Ditto.
	* backend/mustek.c (sane_init): Ditto.

	* frontend/scan.c (parse_scalar): Default to mm again (instead of
 	cm).  Using `mm' as the default is counter-intuitive since the
 	help info is printed with `mm' as the unit.

	* frontend/xscan.c (main): Pass local_only==SANE_FALSE as second
	argument to sane_get_devices().

Sun Jan 12 13:12:45 1997  David Mosberger-Tang  <davidm@azstarnet.com>

	* backend/sane.c (sanei_constrain_value): For string-lists, ignore
 	case and allow prefixes as long as they remain unique.

	* frontend/scan.c (print_option): Print "auto" as a legal option
 	value if the option has capability SANE_CAP_AUTOMATIC set.
	(process_backend_option): If option has SANE_CAP_AUTOMATIC set,
 	let option value of "auto" turn on automatic mode.

Wed Jan  8 19:55:31 1997  David Mosberger-Tang  <davidm@azstarnet.com>

	* backend/Makefile.in (install): Modify install rule so that
	$(libdir) gets added to /etc/ld.so.conf if it isn't there
	already.
	(COMPILE): Use $(SHCFLAGS) instead of $(CFLAGS).
	(LINK): Remove (unused).

 	LINE_DISTANCE_WORKAROUND to NEED_MUSTEK_LINE_DISTANCE_WORKAROUND.
	Include <config.h>.

Thu Dec 12 20:19:26 1996  David Mosberger-Tang  <davidm@azstarnet.com>

	* backend/mustek.h (next): New member.  Forms linked list of open
 	handles.  * backend/mustek.c (first_handle): New variable.  Root
 	of list of open handles.

	(sane_close): Remove handle from list of open handles.

	* backend/mustek.c (attach): Added back MFS-12000SP, MFS-08000SP,
 	and MFS-06000SP.  At least the first one really does exist.  I
 	don't know how the differ from the other scanners, but it looks as
 	if line-distance correction might be different.

	* backend/sane.c (sane_strstatus): Remove trailing dot from error
 	message.

 	maximum size of a string constraint list.
	(init_options): Use max_string_size () to initialize size of
 	string-valued options.

Sun Dec  1 15:44:53 1996  David Mosberger-Tang  <davidm@azstarnet.com>

	* Version 0.1 released.

	* backend/mustek.c (attach): Fix mispelled/bad model names:
