1.0.5    2006 January 30
         Fixed typo in pod (oops!)

         Changed to a Module::Install-based build system

         Updated README file

         PODed INSTALL

         whirlpoolsum(1) utility

         removed examples/ directory, the Digest docs and t/ should be more than enough

         Updater ppport.h with Devel::PPPort

         Relicensed from GPL => GPL/Artistic, see COPYING for rationale.

1.0.4    2006 January 24
         - Added a clone() method that clones the state of the current object and
         - returns the cloned object.

         add and addfile now return current the object so ->add( "foo" )->digest
         works like it does in other digest modules.

         Added a b64digest method that is an alias for the base64digest method.

         Removed (add addfile reset) from @EXPORT_OK, 

         Updated the LICENSE section to the recommended FSF GPL notice

         b64digest no longer returns a trailing ==

1.0.3    2004 August 18
         Modified hashsize() to return number of bits, instead of bytes
         (to become consistent with Digest::SHA of Mark Shelor)

1.0.2    2003 July 29
         Minor code cleanup

1.0.1    Optimized even more
         Refined "files.pl" example script by including error-checking
