ANNOUNCING AFFLIB 2.2

I'm happy to announce the release of AFFLIB 2.2. You can download it
from the standard location at http://www.afflib.org/

Version 2.2 brings several important new features to AFFLIB:

 * AIMAGE now computes SHA256 when an entire image is acquired,
   in addition to also calculating MD5 and SHA1. 

 * Support for AFFLIB running under Windows has been greatly
   expanded. Now AFFLIB compiles on both Cygwin and Microsoft VC++
   (version 2005). Extensive documentation is included in the Win32
   directory for both downloading and installing the (free) Microsoft
   build tools, and for compiling AFFLIB.
