+.SH NAME
+sane-teco2 - SANE backend for TECO / RELISYS scanners
+.SH DESCRIPTION
+The
+.B sane-teco2
+library implements a SANE (Scanner Access Now Easy) backend that
+provides access to some TECO SCSI flatbed scanners. This backend
+should be considered
+.B alpha-quality
+software! TECO scanners are sold under
+various brands like Relisys, Piotech, TRUST. This backend may or
+may not support yours.
+.PP
+The scanners that should work with this backend are:
+.PP
+.RS
+   Vendor Model           TECO model       status
+.br
+----------------------  --------------  -----------
+.br
+  Relisys Scorpio Super 3  VM3575         tested
+  Apollo Express 6         VM656A         tested
+  Scorpio Pro-S            VM6586         tested
+
+.RE
+
+Note that the untested scanner will not be directly supported. You
+should contact the author for that.
+
+The TECO VM number can usually be found at the back of the
+scanner. It is also part of the FCC ID. 
+
+The options the backend supports can either be selected through
+command line options to programs like scanimage or through GUI
+elements in xscanimage or xsane.
+
+.br
+If you have any success with a scanner not listed here, or if you have
+any strange behavior, please report to the backend maintainer or to
+the SANE mailing list.
+
+Valid command line options and their syntax can be listed by using 
+.RS
+scanimage --help -d teco2
+.RE
+
+.TP
+.B Scan Mode
+
+.TP
+.B --mode
+selects the basic mode of operation of the scanner valid choices are 
+.I Black & White
+,
+.I Grayscale
+and
+.I Color
+The Black & White mode is black and white only (1 bit). Grayscale
+will produce 256 levels of gray (8 bits). Color will produce a 24 bits
+color image.
+
+.TP
+.B --resolution
+selects the resolution for a scan. The scanner can do all resolutions
+between 1 and 600, in increments of 1.
+
+
+.TP
+.B Geometry options
+
+.TP
+.B -l -t -x -y 
+control the scan area: -l sets the top left x coordinate, -t the top
+left y coordinate, -x selects the width and -y the height of the scan
+area. All parameters are specified in millimeters by default.
+
+
+.TP
+.B Enhancement options
+
+.TP
+.B --custom-gamma
+(color mode only) allows the user to specify a gamma table (see the
+next 3 parameters).
+
+.TP 
+.B --red-gamma-table 
+(color mode only) can be used to download a user defined
+gamma table for the red channel. The table must be 256 bytes long.
+
+.TP 
+.B --green-gamma-table 
+(color mode only) can be used to download a user defined
+gamma table for the green channel. The table must be 256 bytes long.
+
+.TP
+.B --blue-gamma-table 
+(color mode only) can be used to download a user defined gamma table
+for the blue channel. The table must be 256 bytes long.
+
+
+.TP 
+.B --preview
+requests a preview scan. The resolution used for that scan is 22 dpi
+and the scan area is the maximum allowed. The scan mode is user
+selected. The default is "no".
+
+
+.SH CONFIGURATION FILE
+The configuration file @CONFIGDIR@/teco2.conf supports only one information: the device name to use (eg /dev/scanner).
+
+
+.SH FILES
+.TP
+.I @LIBDIR@/libsane-teco2.a
+The static library implementing this backend.
+.TP
+.I @LIBDIR@/libsane-teco2.so
+The shared library implementing this backend (present on systems that
+support dynamic loading).
+
+
+.SH ENVIRONMENT
+.TP
+.B SANE_DEBUG_TECO2
+If the library was compiled with debug support enabled, this
+environment variable controls the debug level for this backend. E.g.,
+a value of 128 requests all debug output to be printed. Smaller levels
+reduce verbosity.
+
+
+.SH LIMITATIONS
+The windows TWAIN driver has many more options than this SANE
+backend. However they are only software adjustments. This backend only
+implements what the scanner can support.
+
+
+.SH BUGS
+
+Plenty. Parts of this backend are still under development.
