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
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.
