Silicon Graphics has seen fit to allow us to give this work away.  It
is free.  There is no support or guarantee of any sort as to its
operations, correctness, or whatever.  If you do anything useful with
all or parts of it you need to honor the copyright notices.  It would
also be nice to be acknowledged.<p>

The libtiff software was written by Sam Leffler while working for
Silicon Graphics.<p>

The LZW algorithm is derived from the compress program (the proper
attribution is included in the source code).  The Group 3 fax stuff
originated as code from Jef Poskanzer, but has since been rewritten
several times.  The latest version uses an algorithm from Frank
Cringle -- consult <TT>libtiff/mkg3states.c</TT> and
<TT>libtiff/tif_fax3.h</TT> for further information.
The JPEG support was written by Tom Lane and is dependent on the
excellent work of Tom Lane and the Independent JPEG Group (IJG)
who distribute their work under friendly licensing similar to this
software.
Many other people have by now helped with bug fixes and code; a
few of the more persistent contributors have been:
