- 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. Joris Van Damme
- implemented the robust Old JPEG decoder (as included in libtiff since version
- 3.9.0, there was another Old JPEG module in older releases, which was
- incomplete and unsuitable for many existing images of that format). JBIG
- module was written by Lee Howard and depends on JBIG library from the Markus
- Kuhn. Many other people have by now helped with bug fixes and code; a few of
- the more persistent contributors have been:
