ansi2knr.c is included in this distribution by per-
mission of L. Peter Deutsch, sole proprietor of
its copyright holder, Aladdin Enterprises of Men-
lo Park, CA. ansi2knr.c is NOT covered by the
above copyright and conditions, but instead
by the usual distribution terms of the Free Soft-
ware Foundation; principally,that you must in-
clude source code if you redistribute it. (See the
le 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 conguration script "congure" was
produced with GNU Autoconf.
It is copyright by the Free Software Foundation
but is freely distributable.
The same holds for its supporting scripts (con-
g.guess, cong.sub,ltcong, ltmain.sh). An-
other 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 mar-
ginal 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 les.
To avoid entanglement with the Unisys LZW
patent, GIF reading support has
been removed altogether, and the GIF writer
has been simplied to produce
uncompressed GIFs. This technique does not
use the LZW algorithm; the
resulting GIF les 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 prop-
erty of CompuServe Incorporated. GIF(sm) is
a Service Mark property of CompuServe Incor-
porated."

SIL OPEN FONT LICENSE Version 1.1 - 26 Feb-
ruary 2007
PREAMBLE
The goals of the Open Font License (OFL) are to
stimulate worldwide development of collabora-
tive font projects, to support the font creation
efforts of academic and linguistic communities,
and to provide a free and open framework in
which fonts may be shared and improved in
partnership with others.
The OFL allows the licensed fonts to be used,
studied, modied and redistributed freely as
long as they are not sold by themselves. The
fonts, including any derivative works, can be
bundled, embedded, redistributed and/or sold
with any software provided that any reserved
names are not used by derivative works. The
fonts and derivatives,however, cannot be re-
leased under any other type of license. The
requirement for fonts to remain under this li-
cense does not apply to any document created
using the fonts or their derivatives.
