[FEATURE] added exportable function valid_isbn_checksum that takes care of all of the object stuff for you and just gives you the answer. In previous docs, this was called is_valid_checksum even though that conflicted with an object method. It was documented but never implemented. Now it's there. :) [BUGFIX] now should pass tests under 5.6.2, after a bit of backporting. Upgrade already people! :)
Changes for version 2.02_01 - 2007-08-17
Don't import import() from Exporter. There are a lot of people (apparently) using very old perls, not just CPAN Testers.
