ansi2knr.c isincluded in thisdistribution bypermission of L.Peter Deutsch, soleproprietor ofits
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 FreeSoftware Foundationbut isfreely distributable.The sameholds forits supportingscripts
(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 GIFfiles arelarger than usual,but are readableby allstandard GIF
decoders.
