Major contributors
------------------
Special thanks are due to Russell Lang, for the GSview for Windows program,
for contributing most of the code for the Microsoft Windows and OS/2
environments, and for the original version of the PNG driver; to Tim
Theisen, for the Ghostview program for X Windows and for major contributions
to the development and support of code for the X Windows environment; and to
the Independent JPEG Group, for creating the JPEG DCT library that
Ghostscript uses.
