- This is Debian's prepackaged version of the `jpeg library' by the Independent
- JPEG Group.
-
- This package was created by Mark Mickan <mmickan@debian.org> from sources
- which can be found at ftp://ftp.uu.net/graphics/jpeg/jpegsrc.v6b.tar.gz
-
- It is partly based on the libjpeg6a package originally put together by
- Andy Guy <awpguy@acs.ucalgary.ca> and later maintained by Mark Mickan.
-
- Current Debian maintainer is Bill Allombert <ballombe@debian.org>.

- LEGAL ISSUES [ from README supplied with source - MM ]
- ============
-
- In plain English:
-
- 1. We don't promise that this software works. (But if you find any bugs,
- please let us know!)
- 2. You can use this software for whatever you want. You don't have to pay us.
- 3. You may not pretend that you wrote this software. If you use it in a
- program, you must acknowledge somewhere in your documentation 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) 1991-1998, 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 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,
- ltconfig, ltmain.sh). Another support script, install-sh, is copyright
- by M.I.T. but is also freely distributable.
-
- It appears that the arithmetic coding option of the JPEG spec is covered by
- patents owned by IBM, AT&T, and Mitsubishi. Hence arithmetic coding cannot
- legally be used without obtaining one or more licenses. For this reason,
- support for arithmetic coding has been removed from the free JPEG software.
- (Since arithmetic coding provides only a marginal gain over the unpatented
- Huffman mode, it is unlikely that very many implementations will support it.)
- So far as we are aware, there are no patent restrictions on the remaining
- code.
-
- 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."
