What's new in this version:
Revised for Leopard (Mac OS X 10.5) and Snow Leopard (Mac OS X 10.6); universal binary, including 64-bit. [The earlier PPC-only version, compatible with earlier systems and including source code, is still available.] Thorough code revision, many miscellaneous bug fixes. Much nicer "card" display. Animated card replacement. Help documentation now included.
