IJG license

Description
In plain English: 


We don't promise that this software works. (But if you find any bugs,
please let us know!) You can use this software for whatever you want.
You don't have to pay us. 
You may not pretend that you wrote this software. If you use it
in a program, you must acknowledge somewhere in yourdocumentation
that you've used the IJG code. 
 

In legalese: 

The authors make NO WARRANTY or representation, either express or
implied, with respect to this software, its quality, accuracy,
merchantability, or fitness for a particular purpose. This software is
provided "AS IS", and you, its user, assume the entire risk as to its
quality and accuracy. 

This software is copyright (C) 1991-2010, Thomas G. Lane, Guido
Vollbeding. 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 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. 

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 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, ltmain.sh). Another support script,
install-sh, is copyright by X Consortium but is also freely
distributable. 

The IJG distribution formerly included code to read and write GIF
files. To avoid entanglement with the Unisys LZW patent, GIF reading
support has been removed altogether, and the GIF writer has been
simplified to produce "uncompressed GIFs". This technique does not use
the LZW algorithm; the resulting GIF files are larger than usual, but 
are readable by all standard GIF decoders. 

We are required to state that "The Graphics Interchange Format(c) is
the copyright property of CompuServe Incorporated. GIF(sm) is a
Service mark property of CompuServe Incorporated."
