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 unmodified library. If you use our work, you ought to acknowledge us.

Permission is NOT granted for the use of any IJG author's name or company name in

advertising or publicity relating to this software or products derived from it. This software

may be referred to only as "the Independent JPEG Group's software".

We specifically permit and encourage the use of this software as the basis of commercial

products, provided that all warranty or liability claims are assumed by the product vendor.

Software Foundation; 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.
