Records from the Fedora Core License Audit

Only changes are some minor email obfuscation and the removal of phone numbers.

Netpbm

Netpbm and friends are a huge mess of mixed code, some without attribution. Starting with the excellent copyright analysis done by Debian, found here:
http://packages.debian.org/changelogs/pool/main/n/netpbm-free/netpbm-free_10.0-8sarge3/netpbm.copyright
In addition, the LZW patent has expired, so ppmtogif is ok. Fedora Core's netpbm-progs package doesn't have jbigtopnm or pnmtojbig (later removed from the SRPM). The badly licensed hpcdtoppm isn't in the Fedora package in either source or binary format. This only leaves the bits that are listed in the Debian copyright as "Unknown, So Not Distributed". So, lets try to resolve those:
pamchannel: Public Domain (OK)
pamtopnm: Public Domain (OK)

pbmtolps (netpbm)

Greg Roelofs helped me find the author of pbmtolps, George Phillips.
He chose LGPL for the license of this code.

Hi, Tom.  I've picked a license.  Here's what I believe to be an
official,
authoritative and legally binding statement.

To whom it may concern, I, George Phillips the sole author of pbmtolps,
place
the source code for pbmtolps under the GNU Lesser General Public License
(http://www.gnu.org/copyleft/lesser.html).

George,

Thanks for taking the time to clear this up. We just need you to let us
know what license the pbmtolps code is under.

Here is a list of licenses from the Free Software Foundation:
http://www.fsf.org/licensing/licenses/index_html#GPLCompatibleLicenses

Start with the GPL Compatible Free Licenses, and move down (there are
Non-Free Licenses at the bottom, if you choose one of those, it will not
make it into Fedora).

Some of the other pieces of code in the netpbm packages have been
licensed under the GPL, BSD, and Artistic licenses.

When you've picked one, email me back and let me know. We'll add the
license to the code and include it with Fedora!

Thanks again,

~tom

Very much so, thanks!  I'll forward this on to Tom 'spot' Callaway, who's
the Red Hat guy (or one of them) taking the lead on this stuff.

I appreciate the response!

pbmto4425 (netpbm)

Contacted author, this code is GPL.

First email:

I am indeed the Robert Perlberg who wrote pbmto4425.  I'm amazed that
anyone still cares about that program.  *I* don't even use it any
more.  :-)

I'm not sure what you're looking for in the way of licensing info.
It's just something I posted to net.sources a long time ago.  So, yes,
it is freeware, open source code.  That is, until people stop using
high resolution color graphics displays and go back to using ASCII
terminals, then I'll really clean up, baby!  :-)

Thank for your interest.

I was thinking more along the lines of pbmto4425 being covered by the
GPL.

I am aware that it has been a part of Linux since the first version of
Linux I ever saw.  My coworkers were quite impressed when I pointed it
out.  I was quite surprised when it was made part of netpbm.

pbmtoln03 (netpbm)

Contacted author, code is Perl Artistic.

Tom,

Gee, that was a long time ago, but yes, I am the one.

I think I would have been assuming that my contribution would have
fallen under whatever license pbmplus was using at the time.

If you can not find such an attribution, then I am happy for this module
to be accessible under the Perl Artistic License (1997).

Yes, that is me. I can't remember what license I originally put it under. I'm
happy to put in under the same license as Jef Poskanzer used for the rest of
PBM, if that helps.

That would be the MIT license:

Also, we're missing license attribution for pktopbm.c and ppmtopjxl.c,
would you like to have these be MIT licensed as well?

Thanks in advance,
