Here is an analysys of Netpbm copyrights done by Steve McIntyre
<stevem@chiark.greenend.org.uk> finishing on October 7, 2001.

It is based on Netpbm 9.20, so it doesn't cover material added since
then.



Copyright:
==========

Netpbm has a very complicated licensing setup, as it is a collection
of hundreds of small utility programs, each with an individual
copyright/license. From inspection of the source and documentation in
the package, I believe the following programs are DFSG-free. They have
a variety of licenses, which I have summarised below for convenience.

A:  The most common netpbm license - clearly the original from Jef Poskanzer:

    Permission to use, copy, modify, and distribute this software and its
    documentation for any purpose and without fee is hereby granted, provided
    that the above copyright notice appear in all copies and that both that
    copyright notice and this permission notice appear in supporting
    documentation.  This software is provided "as is" without express or
    implied warranty.

The core libp[gbnp]m library code all also seems to follow this license.

B:  The standard BSD license. See /usr/share/common-licenses/BSD

C:  GNU General Public License v2. See /usr/share/common-licenses/GPL.

D:  The Independent JPEG Group license:

    Permission is hereby granted to use, copy, modify, and distribute
    this software (or portions thereof) for any purpose, without fee,
    subject to these conditions: (1) If any part of the source code
    for this software is distributed, then this README file must be
    included, with this copyright and no-warranty notice unaltered;
    and any additions, deletions, or changes to the original files
    must be clearly indicated in accompanying documentation.  (2) If
    only executable code is distributed, then the accompanying
    documentation must state that "this software is based in part on
    the work of the Independent JPEG Group".  (3) Permission for use
    of this software is granted only if the user accepts full
    responsibility for any undesirable consequences; the authors
    accept NO LIABILITY for damages of any kind.

    These conditions apply to any software derived from or based on
    the IJG code, not just to the unmodified library.  If you use our
    work, you ought to acknowledge us.

    Permission is NOT granted for the use of any IJG author's name or
    company name in advertising or publicity relating to this software
    or products derived from it.  This software may be referred to
    only as "the Independent JPEG Group's software".

    We specifically permit and encourage the use of this software as
    the basis of commercial products, provided that all warranty or
    liability claims are assumed by the product vendor.

E:  This software is copyrighted as noted below.  It may be freely copied,
    modified, and redistributed, provided that the copyright notice is
    preserved on all copies.

    There is no warranty or other guarantee of fitness for this software,
    it is provided solely "as is".  Bug reports or fixes may be sent
    to the author, who may or may not act on them as he desires.

    You may not include this software in a program or other software product
    without supplying the source, or without informing the end-user that the
    source is available for no extra charge.
    
    If you modify this software, you should include a notice giving the
    name of the person performing the modification, the date of modification,
    and the reason for such modification.

F:  The program and documentation may be freely distributed by anyone in source
    or binary format. Please clearly note any changes.

G:  Public domain:

    This software is in the public domain.  Permission to use, copy,
    modify, and distribute this software and its documentation for any
    purpose and without fee is hereby granted, without any conditions or
    restrictions.

H:  Public domain, slightly different wording:

    Permission  to  use, copy, modify, and distribute this software and
    its documentation  for  any  purpose  and  without  fee  is  hereby
    granted,  without any conditions or restrictions.  This software is
    provided "as is" without express or implied warranty.

I:  A variation on the BSD license

    Permission to use, copy, modify, distribute, and  sell  this
    software  and  its  documentation  for any purpose is hereby
    granted without  fee,  provided  that  the  above  copyright
    notice  appear  in  all  copies and that both that copyright
    notice and this permission notice appear in supporting documentation,
    and  that  the  name  of the  Smithsonian Astrophysical
    Observatory not be used in advertising or publicity
    pertaining to distribution of the software without specific,
    written  prior  permission.   The Smithsonian  Astrophysical
    Observatory makes no representations about  the  suitability
    of  this  software for any purpose.  It is provided  "as is"
    without express or implied warranty.
    THE  SMITHSONIAN  ASTROPHYSICAL  OBSERVATORY  DISCLAIMS  ALL

    IMPLIED  WARRANTIES  OF  MERCHANTABILITY AND FITNESS, IN  NO

    OR ANY DAMAGES WHATSOEVER RESULTING FROM LOSS  OF USE,  DATA
    OR  PROFITS, WHETHER IN AN ACTION OF CONTRACT, NEGLIGENCE OR
    OTHER TORTIOUS ACTION, ARISING OUT OF OR IN CONNECTION  WITH
    THE  USE OR PERFORMANCE OF THIS SOFTWARE.
