52063bb805SMatt Madiaansi2knr.c is included in this distribution by permission of L. Peter Deutsch,
53063bb805SMatt Madiasole proprietor of its copyright holder, Aladdin Enterprises of Menlo Park, CA.
54063bb805SMatt Madiaansi2knr.c is NOT covered by the above copyright and conditions, but instead
55063bb805SMatt Madiaby the usual distribution terms of the Free Software Foundation; principally,
56063bb805SMatt Madiathat you must include source code if you redistribute it.  (See the file
57063bb805SMatt Madiaansi2knr.c for full details.)  However, since ansi2knr.c is not needed as part
58063bb805SMatt Madiaof any program generated from the IJG code, this does not limit you more than
59063bb805SMatt Madiathe foregoing paragraphs do.

61063bb805SMatt MadiaThe Unix configuration script "configure" was produced with GNU Autoconf.
62063bb805SMatt MadiaIt is copyright by the Free Software Foundation but is freely distributable.
63063bb805SMatt MadiaThe same holds for its supporting scripts (config.guess, config.sub,
64063bb805SMatt Madialtmain.sh).  Another support script, install-sh, is copyright by X Consortium
65063bb805SMatt Madiabut is also freely distributable.

67063bb805SMatt MadiaThe IJG distribution formerly included code to read and write GIF files.
68063bb805SMatt MadiaTo avoid entanglement with the Unisys LZW patent, GIF reading support has
69063bb805SMatt Madiabeen removed altogether, and the GIF writer has been simplified to produce
70063bb805SMatt Madia"uncompressed GIFs".  This technique does not use the LZW algorithm; the
71063bb805SMatt Madiaresulting GIF files are larger than usual, but are readable by all standard
72063bb805SMatt MadiaGIF decoders.
