This file contains information about the TWAIN 1.6 Software Development Kit
(SDK) for Windows NT on Digital(tm) Alpha(tm) processors.

For support and additional questions on this particular kit,

This kit is an adaptation of the TWAIN 1.6 SDK for Windows NT and Windows 95
for X86 processors as distributed by the TWAIN Working Group
(http://www.twain.org).

Here are the instructions for installing the kit:

(It is assumed that you have MS Visual C++ 2.0 or later for Digital Alpha).

- Save the TWAlpha.zip file to a temporary directory.

- Unzip the TWAlpha.zip file.

- Run setup.exe from the temporary directory.

The same documentation (*.doc, *.txt) files as for X86 processors apply
with the following exceptions:

- All references to "Alpha" in those documentation files are in the context
of "Alpha" versus "Beta" version releases rather than an Alpha processor.

- There are no 16-bit thunk related binary files since we do not know of any
native 16-bit TWAIN compatible applications for DIGITAL Alpha in existence.

- The relevant makefiles (*.mak) files have been modified to contain
relative paths instead of absolute paths. This allows for source files to
be installed in any subdirectory.

- The debug and release versions of object files will be generated in separate
subdirectories (i.e. ..\32\debug and ..\32\release).

- If your compiler and linker are not installed in paths assumed by the build
batch (..\BAT\*.bat) files, we suggest that you ignore these files altogether.
Instead, you may go to the appropriate subdirectory and build as follows:

	cd ..\CODE\twack\32
	nmake -f twack_32.mak CFG="Win32 Release"	OR
    nmake -f twack_32.mak CFG="Win32 Debug"

	cd ..\..\twsrc\32
	nmake -f twsrc_32.mak CFG="Win32 Release"	OR
	nmake -f twsrc_32.mak CFG="Win32 Debug"


Here are the default installtion directories for the kit:

C:\twack  (may be modified during setup)

	- twack_32.exe : TWAIN application for autotesting

C:\twack\CODE\twack

	- subdirectory for sample application and autotest source files

C:\twack\CODE\twsrc

	- subdirectory for sample Data Source files

C:\twack\CODE\twcommon

	- subdirectory for common header and source files

C:\Winnt  (or equivalent 'WINDIR' directory)

	- twain_32.dll : Data Source Manager DLL

	- twacker.ini : Data source initialization file

	- twsrc_32.ds : Data Source file will be in subdirectory ..\twain_32.

	- default.src : default scanner emulation

C:\temp (hardwired directory)

	- verify.tat : file for testing proper installation of the kit binary files

	- test?.tat : script files for additional testing

	- *.txt and *.doc documentation files

C:\	  (hardwired directory)

	- default.src and scanjet.src data source emulation

	- *.bmp : any bitmap image files (not provided in the kit)

or data sources, check the TWAIN Working Group Web site
