This software is copyright (C) 1991-1998, Thomas G. Lane.
All Rights Reserved except as specified below.
Permission is hereby granted to use, copy, modify, and distribute this software (or portions thereof) for
any purpose, without fee, subject to these conditions:
(1) If any part of the source code for this software is distributed, then this README file must be
included, with this copyright and no-warranty notice unaltered; and any additions, deletions, or
changes to the original files must be clearly indicated in accompanying documentation.
(2) If only executable code is distributed, then the accompanying documentation must state that “this
software is based in part on the work of the Independent JPEG Group”.
(3) Permission for use of this software is granted only if the user accepts full responsibility for any
undesirable consequences; the authors accept NO LIABILITY for damages of any kind.
These conditions apply to any software derived from or based on the IJG code, not just to the

ansi2knr.c is included in this distribution by permission of L. Peter Deutsch, sole proprietor of its
copyright holder, Aladdin Enterprises of Menlo Park, CA. ansi2knr.c is NOT covered by the above
copyright and conditions, but instead by the usual distribution terms of the Free Software Founda-
tion; principally, that you must include source code if you redistribute it. (See the file ansi2knr.c for full
details.) However, since ansi2knr.c is not needed as part of any program generated from the IJG code,
this does not limit you more than the foregoing paragraphs do.
The Unix configuration script “configure” was produced with GNU Autoconf. It is copyright by the Free
Software Foundation but is freely distributable. The same holds for its supporting scripts (config.guess,
config.sub, ltconfig, ltmain.sh). Another support script, install-sh, is copyright by M.I.T. but is also freely
distributable.
