+WIASANE
+=======
+The WIASANE project provides a Windows Image Acquisition (WIA) Driver
+which enables image acquisition from scanner devices through the
+Scanner Access Now Easy (SANE) network protocol.
+
+This WIA driver implements a SANE frontend on top of the SANE network
+protocol. It is referred to as Scanner Access Now Easy - WIA Driver.
+
+In order to access those scanner devices either the scanner itself or
+a SANE daemon needs to provide a SANE network frontend to be used.
+
+Requirements
+------------
+This software is currently build and tested against Windows 7.
+The required Windows API functions are available since Windows Vista,
+which means that it could work on Windows Vista and newer versions.
+
+Features
+--------
+- Create a Windows scanner device by connecting to a SANE device
+- Support for color, grayscale and lineart/threshold scan modes
+- Support for preview and final scan types
+- Support for contrast and brightness settings
+- Support for single-sided scanning from a flatbet
+- Integrated wizard during driver/device installation
+
+To be implemented
+-----------------
+- Support for username- und password-based authentication (in progress)
+- Support for automatic document feeder and duplex mode (in progress)
+- Integrated property page for device modification (in progress)
+
+To be improved
+--------------
+- Make WIA driver use use asynchronous network connections
+- Make wizard and property pages use asynchronous device I/O
+- Handling of rounding issues while converting between units of length
+
+Development and Build environment
+---------------------------------
+As stated before, this software package is currently being developed
+and build against Windows 7 as well as Windows Driver Kit 8.0.
+
+All Visual Studio project files are created, modified, tested and used
+with Visual Studio 2012. This version is also used to build the
+released driver packages as well as included libraries and applications.
+
+The installer is created and compiled using Inno Setup 5.5 or newer.
