Many people have contributed to the development of SchemeChecker. I would like to thank the following:

- Giovanni Sarbia who created the ResSet external (for fixing incorrectly set bits) which was put to use from version 1.2.

- Lloyd Wood who sent me lots of bug reports, comments and suggestions.

- Tom Connolly who wrote the external versions prior to 1.2 used to fix incorrectly set bits.

- Luciano de Castro who discovered two very serious bugs in the 'final candidate' versions.

- Scott Hunter who made the original SchemeChecker icon.

- Virginia B. Lindsey who made sure the new icon looked consistent in all bit-depths.

- Scott Naness, Jeremy Gale, Virginia B. Lindsey, Ed Deans, David Artur Daix, Chris Barnett, Bruce Bennet and Eric Blair who sent me feedback, comments and bug reports during the many beta versions.

And, last, but not least, I would like to thank Gregory D. Landweber for making Kaleidoscope.
