+.SH NAME
+sane\-gphoto2 \- SANE backend for gphoto2 supported cameras
+.SH DESCRIPTION
+The
+.B sane\-gphoto2
+library implements a SANE (Scanner Access Now Easy) backend that
+provides access to the digital cameras supported by gphoto2. 
+This backend has only been tested with a handful of cameras so far.  Patches
+to support other models are welcome.
+.PP
+Because of the limited testing of this backend, it is commented out
+in @CONFIGDIR@/dll.conf by default.  Either the comment
+character must be removed or the backend must be called explicitly.
+E.g. `scanimage \-d gphoto2' or `xscanimage gphoto2'.
+.SH "DEVICE NAMES"
+The current version of the backend only allows one camera to be
+connected.  The device name is always "0".
+.SH CONFIGURATION
+The contents of the
+.I gphoto2.conf
+specify the characteristics of the camera to be used.   Resolutions
+(high resolution, low resolution, and thumbnail size) are
+required since they are needed by the sane frontends, but can't be obtained
+through the gphoto2 interface.  Valid ports and cameras can be obtained
+by "gphoto2 \-\-list\-cameras" and "gphoto2 \-\-list\-ports".
+.PP
+The dumpinquiry line causes some information about the camera to 
+be printed.
+.PP
+Empty lines and lines starting with a hash mark (#) are
+ignored.  A sample configuration file is shown below:
+.PP
+The "topfolder" line specifies the "fixed" part of the file path.  For 
+example, on the Kodak DC-240, files are stored in the directory 
+/DCIM/100DC240.  The /DCIM portion is constant, but 100DC240 will
+change and must be read from the camera.  In this case, the 
+line would read "topfolder=/DCIM"
+.PP
+Some cameras don't implement a file structure and store all pictures
+in the "/" directory.  This is indicated by setting "subdirs=0" with
+"topfolder=/"

+.SH FILES
+.TP
+.I @CONFIGDIR@/gphoto2.conf
+The backend configuration file (see also description of
+.B SANE_CONFIG_DIR
+below).
+.TP
+.I @LIBDIR@/libsane\-gphoto2.a
+The static library implementing this backend.
+.TP
+.I @LIBDIR@/libsane\-gphoto2.so
+The shared library implementing this backend (present on systems that
+support dynamic loading).
+
+.SH ENVIRONMENT
+.TP
+.B SANE_CONFIG_DIR
+This environment variable specifies the list of directories that may
+contain the configuration file.  Under UNIX, the directories are
+separated by a colon (`:'), under OS/2, they are separated by a
+semi-colon (`;').  If this variable is not set, the configuration file
+is searched in two default directories: first, the current working
+directory (".") and then in @CONFIGDIR@.  If the value of the
+environment variable ends with the directory separator character, then
+the default directories are searched after the explicitly specified
+directories.  For example, setting
+.B SANE_CONFIG_DIR
+to "/tmp/config:" would result in directories "tmp/config", ".", and
+"@CONFIGDIR@" being searched (in this order).
+.TP
+.B SANE_DEBUG_GPHOTO2
+If the library was compiled with debugging support enabled, this
+environment variable controls the debug level for this backend. 
+A value of 128 requests maximally copious debug output; smaller
+levels reduce verbosity.
+.TP 
+.B GP_DEBUG
+Set to 1, 2, or 3, to enable various levels of debugging within the 
+gphoto2 libraries.
